Instalasi GNS3 Graphical Network Simulator

2011-01-23T00:51:00.001+07:00

GNS3 is a Graphical Network Simulator that allows emulation of complex networks. You may be familiar with VMWare or Virtual PC that are used to emulate various operating systems in a virtual environment. These programs allow you to run operating systems such as Windows XP Professional or Ubuntu Linux in a virtual environment on your computer. GNS3 allows the same type of emulation using Cisco Internetwork Operating Systems. It allows you to run a Cisco IOS in a virtual environment on your computer. GNS3 is a graphical front end to a product called Dynagen. Dynamips is the core program that allows IOS emulation. Dynagen runs on top of Dynamips to create a more user friendly, text-based environment. A user may create network topologies using simple Windows ini-type files with Dynagen running on top of Dynamips. GNS3 takes this a step further by providing a graphical environment.
GNS3 allows the emulation of Cisco IOSs on your Windows or Linux based computer. Emulation is possible for a long list of router platforms and PIX firewalls. Using an EtherSwitch card in a router, switching platforms may also be emulated to the degree of the card’s supported functionality. This means that GNS3 is an invaluable tool for preparing for Cisco certifications such as CCNA and CCNP. There are a number of router simulators on the market, but they are limited to the commands that the developer chooses to include. Almost always there are commands or parameters that are not supported when working on a practice lab. In these simulators you are only seeing a representation of the output of a simulated router. The accuracy of that representation is only as good as the developer makes it. With GNS3 you are running an actual Cisco IOS, so you will see exactly what the IOS produces and will have access to any command or parameter supported by the IOS. In addition, GNS3 is an open source, free program for you to use. However, due to licensing restrictions, you will have to provide your own Cisco IOSs to use with GNS3. Also, GNS3 will provide around 1,000 packets per second throughput in a virtual environment. A normal router will provide a hundred to a thousand times greater throughput. GNS3 does not take the place of a real router, but is meant to be a tool for learning and testing in a lab environment. Using GNS3 in any other way would be considered improper.

How To Disable Picture And Fax Viewer

2011-01-19T14:50:00.001+07:00

We all know that WinXP likes to keep itself held together, and how it doesnt like you uninstalling certain components. Well The Picture and Fax Viewer, is one of these programs which can cause problems if removed incorrectly. It can be disabled safely as follows:

[Start] [Run] type regedit and click [OK]

Navigate to :

HKEY_CLASSES_ROOT/ SystemFileAssociations/ image/ ShellEx/ ContextMenuHandlers

then delete the Folder ShellImagePreview under ContextMenuHandlers

Note: If you want to restore the Picture and Fax Viewer :

Create the ShellImagePreview folder and create the String Value (Default)
Assign it the value {e84fda7c-1d6a-45f6-b725-cb260c236066}

NOTE: This tweak doesnt uninstall the program. It removes the association and therefore it cannot be run.

Check For Dos, Check to see if you are infected.

2011-01-19T14:38:00.000+07:00

When you first turn on you computer (BEFORE DIALING INTO YOUR ISP),
open a MS-DOS Prompt window (start/programs MS-DOS Prompt).
Then type netstat -arn and press the Enter key.
Your screen should display the following (without the dotted lines
which I added for clarification).

-----------------------------------------------------------------------------
Active Routes:

   127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1

--------------------------------------------------------------------------------

If you see anything else, there might be a problem (more on that later).
Now dial into your ISP, once you are connected;
go back to the MS-DOS Prompt and run the same command as before
netstat -arn, this time it will look similar to the following (without
dotted lines).

-------------------------------------------------------------------------------------

Active Routes:

  Network Address Netmask Gateway Address Interface Metric

  TCP 216.1.104.70:139 0.0.0.0:0 LISTENING
  UDP 216.1.104.70:137 *:*

--------------------------------------------------------------------------------

What you are seeing in the first section (Active Routes) under the heading of
Network Address are some additional lines. The only ones that should be there
are ones belonging to your ISP (more on that later). In the second section
(Route Table) under Local Address you are seeing the IP address that your ISP
assigned you (in this example 216.1.104.70).

The numbers are divided into four dot notations, the first three should be
the same for both sets, while in this case the .70 is the unique number
assigned for THIS session. Next time you dial in that number will more than
likely be different.

To make sure that the first three notation are as they should be, we will run
one more command from the MS-DOS window.
From the MS-DOS Prompt type tracert /www.yourispwebsite.com or .net
or whatever it ends in. Following is an example of the output you should see.

---------------------------------------------------------------------------------------

Tracing route to /www.motion.net [207.239.117.112]over a maximum of 30 hops:

3 108 ms 116 ms 119 ms www.motion.net [207.239.117.112]
Trace complete.

------------------------------------------------------------------------------------------

You will see that on lines with the 1 and 2 the first three notations of the
address match with what we saw above, which is a good thing. If it does not,
then some further investigation is needed.

If everything matches like above, you can almost breath easier. Another thing
which should you should check is programs launched during startup. To find
these, Click start/programs/startup, look at what shows up. You should be
able to recognize everything there, if not, once again more investigation is
needed.

-------------------------------------------------------------------------------------------

Now just because everything reported out like we expected (and demonstrated
above) we still are not out of the woods. How is this so, you ask? Do you use
Netmeeting? Do you get on IRC (Internet Relay Chat)? Or any other program
that makes use of the Internet. Have you every recieved an email with an
attachment that ended in .exe? The list goes on and on, basically anything
that you run could have become infected with a trojan. What this means, is
the program appears to do what you expect, but also does just a little more.
This little more could be blasting ebay.com or one of the other sites that
CNNlive was talking about.

What can you do? Well some anti-virus software will detect some trojans.
Another (tedious) thing is to start each of these "extra" Internet programs
one at a time and go through the last two steps above, looking at the routes
and connection the program uses. However, the tricky part will be figuring
out where to tracert to in order to find out if the addresses you see in
step 2 are "safe" or not. I should forewarn you, that running tracert after
tracert, after tracert might be considered "improper" by your ISP. The steps
outlined above may not work exactly as I have stated depending upon your ISP,
but with a true ISP it should work. Finally, this advise comes with NO
warranty and by following my "hints' you implicitly release me from ANY and
ALL liability which you may incur.

Other options

Display protocol statistics and current TCP/IP network connections.
Netstat [-a] [-e] [-n] [-s] [-p proto] [-r] [intervals]

-a.. Display all connections and listening ports.
-e.. Display Ethernet statistics. This may be combined with the -s option.
-n.. Diplays address and port numbers in the numerical form.
-p proto..Shows connections for the protocol specified by proto; proto may be
TCP or UDP. If used with the -s option to display per-protocol statistics,
proto may be TCP, UDP, of IP.
-r.. Display the routing table.
-s.. Display per-protocol statistics. By default, statistics are shown for TCP
UDP and IP; the -p option may be used to specify a subset of the default
interval..Redisplay selected statistics, pausing intervals seconds between each

Getting started with Linux

2011-01-19T14:32:00.000+07:00

What is Linux?
Trying it out
Installing
What to do now
The Console

Intro:
This tutorial is written with the total Linux n00b in mind.
I've seen too many n00bs get totally left in the dark by asking what
the best distro is. They seem to only get flooded with too many
answers in so short a time. I'm a little bit of a n00b too, so I know
how it feels. I will cover a grand total of two basic distros. You may
learn to strongly prefer other ones (I do!) but this is just to get
you started. I touch on a number of topics that would be impossible to
go into in depth in one tutorial, so I encourage you to actively seek
out more about the concepts I make reference to.

1. What is Linux?

Linux is basically an operating system (OS for short). The Windows
machine you're (probably) using now uses the Mcft Windows
operating system.

Ok, so what's so different about Linux?

Linux is part of a revolutionary movement called the open-source
movement. The history and intricacies of that movement are well beyond
the scope of this tutorial, but I'll try and explain it simply. Open
source means that the developers release the source code for all their
customers to view and alter to fit what they need the software to do,
what they want the software to do, and what they feel software should
do. Linux is a programmer?s dream come true, it has the best compilers,
libraries, and tools in addition to its being open-source. A
programmer's only limit then, is his knowledge, skill, time, and
resolve.

What is a distro?

A distro is short for a distribution. It's someone's personal
modification or recreation of Linux.

What do you mean by distros? I just want Linux!

Since Linux is open source, every developer can write his own version.
Most of those developers release their modifications, or entire
creations as free and open source. A few don't and try to profit from
their product, which is a topic of moral debate in the Linux world.
The actual Linux is just a kernel that serves as a node of
communication between various points of the system (such as the CPU,
the mouse, the hard drive etc.). In order to use this kernel, we must
find a way to communicate with it. The way we communicate is with a
shell. Shells will let us enter commands in ways that make sense to
us, and send those commands to the kernel in ways that makes sense to
it. The shell most Linux's use it the BASH shell (Bourne Again SHell).
The kernel by itself will not do, and just a shell on top of the kernel
won?t either for most users; we are then forced to use a distribution.

What distro is best?

This is not the question you want to ask a large number of people at
one time. This is very much like asking what kind of shoe is best,
you'll get answers anywhere from running shoes, hiking boots, cleats,
to wingtips. You need to be specific about what you plan on using
Linux for, what system you want to use it on, and many other things. I
will cover two that are quick and easy to get running. They may not be
the best, or the quickest, or the easiest, or the most powerful, but
this is a guide for getting started, and everyone has to start
somewhere.

How much does it cost?

computer + electricity + internet + CD burner and CDs = Linux
I'll let you do your own math.
Note however that a few do charge for their distros, but they aren't
all that common, and can be worked around. Also, if you lack internet
access or a CD burner or CDs or you just want to, you can normally
order CDs of the distro for a few dollars apiece.

2. Trying it out.

Wouldn't it stink if you decide to wipe out your hard drive and install
Linux as the sole operating system only to learn that you don't know
how to do anything and hate it? Wouldn?t it be better to take a test
drive? 95 out of a 100 of you know where I'm heading with this section
and can therefore skip it. For those of you who don't know, read on.

There are many distros, and most distros try to have something that
makes them stand out. Knoppix was the first live-CD distro. Although
most of the other main distros have formed their own live-CDs, Knoppix
is still the most famous and I will be covering how to acquire it.

A live-CD distro is a distribution of Linux in which the entire OS can
be run off of the CD-ROM and your RAM. This means that no installation
is required and the distro will not touch your hard disk or current OS
(unless you tell it to). On bootup, the CD will automatically detect
your hardware and launch you into Linux. To get back to Windows, just
reboot and take the CD out.

Go to the Knoppix website (www.knoppix.com). Look around some to get
more of an idea on what Knoppix is. When you're ready, click Download.
You'll be presented with a large amount of mirrors, some of which have
ftp and some of which have http also.

note: the speed of the mirrors vary greatly, and you may want to
change mirrors should your download be significantly slow.

Choose a mirror. Read the agreement and choose accept. You'll probably
want to download the newest version and in your native language (I'll
assume English in this tutorial). So choose the newest file ending in
-EN.iso

note: you might want to also verify the md5 checksums after the
download, if you don't understand this, don't worry too much. You just
might have to download it again should the file get corrupted (you'll
have to anyway with the md5). Also, a lot of times a burn can be
botched for who-knows what reason. If the disk doesn?t work at all,
try a reburn.

Once the .iso file is done downloading, fire up your favorite
CD-burning software. Find the option to burn a CD image (for Nero, this
is under copy and backup) and burn it to a disk. Make sure you don't
just copy the .iso, you have to burn the image, which will unpack all
the files onto the CD.

Once the disk is done, put it in the CD-ROM drive and reboot the
computer. While your computer is booting, enter CMOS (how to get to
CMOS varies for each computer, some get to it by F1 or F2 or F3, etc.)
Go to the bootup configuration and place CD-ROM above hard disk. Save
changes and exit. Now, Knoppix will automatically start. You will be
presented with a boot prompt. Here you can input specific boot
parameters (called cheatcodes), or just wait and let it boot up using
the default.

note: Sometimes USB keyboards do not work until the OS has somewhat
booted up. Once you?re actually in Knoppix, your USB keyboard should
work, but you may not be able to use cheatcodes. If you need to,
attach a PS/2 keyboard temporarily. Also, if a particular aspect of
hardware detection does not work, look for a cheatcode to disable it.
Cheatcodes can be found on the Knoppix website in text format (or in
HTML at www.knoppix.net/docs/index.php/CheatCodes).

Upon entering the KDE desktop environment, spend some time exploring
around. Surf the web, get on IM, play some games, explore the
filesystem, and whatever else seems interesting. When your done, open
up the console (also called terminal, xterm, konsole, or even shell)
and get ready for the real Linux. See section V for what to do from
here.

note: to function as root (or the superuser) type su.

It's not entirely necessary that you are a console wizard at this point
(although you will need to be sooner or later), but a little messing
around wont hurt.

Just as there are many Linux distros, so there are also many types of
Knoppix. I won?t go into using any of them, but they should all be
somewhat similar. Some of them include: Gnoppix, Knoppix STD, Morphix,
and PHLAK. Other distros also have live-CDs.

3. Installing

I will guide you through the installation of Fedora Core 2. The reason
I chose Fedora is because it contains the Anaconda installer, which is
a very easy installer.

Download the discs from here:
http://download.fedora.redhat.com/pub/fedo...ore/2/i386/iso/
If the link doesn?t work, then go to www.redhat.com and navigate your
way to downloading Fedora (odds are your architecture is i386).
You will want to download the FC2-i386-disc1.iso and burn it using the
method for Knoppix. Do the same for all the discs.

Note: do NOT download the FC2-i386-SRPMS-disc1.iso files.

Now, once you?re ready, insert disc 1 into the drive and reboot.

The installer should come up automatically (if not, then see the
Knoppix section on CMOS).

Note: installer may vary depending on version. Follow directions best
you can using your best judgement.

Language: choose English and hit enter
Keyboard: choose us (probably) and hit enter
Installation media: choose local CDROM (probably) and hit enter
CD test: you can choose to test or skip
Intro: click next
Monitor: choose your monitor to the best of your ability, if you?re unsure, choose on of the generic ones
Installation type: choose which ever you want (default should be fine)
Partition: choose to automatically partition (unless you know what you?re doing)
Partition: the default partitions should suffice.
Boot loader: choose your boot loader (grub for default)
Network settings: choose the correct settings for your network (generally, don?t mess with anything unless you know what you?re doing)
Firewall: you can choose a firewall if you want to
Language support: choose any additional language support you want
Time zone: pick your time zone
Root password: set your root password (root is the admin, or superuser; you want it to be very secure)
Packages: choose which packages you want to install. For hard drives over 10 gigs, you can go ahead and choose all packages (depending on how much disk space you plan on taking up later, note that most everything you?ll need is a package: the exception being large media files). You will generally want to install all the packages you think you?ll ever need. Two desktop environments aren't ecessary.Make sure you have at least one and the X window system! (if you want a GUI that is). I suggest you get all the servers too.Note: Knoppix uses the KDE Desktop environment.
Make sure everything is all right, and install
You can create a boot disk if you want

Note: Desktop environments might have a set-up once you enter them

4. What to do now

Now that you have a Linux set-up and running, there are many paths you
can head down. First, you should explore your GUI and menus. Browse
the web with Mozilla, get on IM with GAIM, play games, add/delete
users, check out OpenOffice, and anything else that might be part of
your daily use. Also, set up a few servers on your computer to play
around with, specifically SMTP (*wink*wink*), FTP (vsftp is a good
one), and either telnet or SSH (OpenSSH is a good one). The setup and
use of these are beyond the scope of this tutorial, but researching
them could prove to be very educational.

The filesystem
The Linux (and Unix) filesystem is different from the normal Windows
that you?re used to. In Windows, your hard drive is denoted ?C:\? (or
whatever). In Linux, it is called the root directory and is denoted
?/?. In the / directory, there are several default folders, including
dev (device drivers) mnt (mount) bin (binaries) usr (Unix System
Resources) home, etc, and others. I encourage you to explore around
the whole file system (see section V) and research more.

Once you are well situated, it?s time to get into the heart and power
of Linux: the console. The next session will guide you through it and
set you on the path to finding out how to do stuff for yourself. You
will (probably) want to start learning to rely less and less on the
GUI and figure out how to do everything through the console (try
launching all your programs from the console, for example).

5. The Console

The Console might look familiar to DOS if you?ve ever used it. The
prompt should look something like the following:

AvatharTri@localhost avathartri$

With the blinking _ following it. This can vary greatly as it is fully
customizable. Let?s get started with the commands.

First, let?s explore the file system. The command ls will "list" the
files in the current directory. Here?s an example:

AvatharTri@localhost avathartri$ ls

It should then display the contents of the current directory if there
are any. Almost all commands have options attached to them. For
example, using the -l option, which is short for "long" will display
more information about the files listed.

AvatharTri@localhost avathartri$ ls -l

We will get into how to find out the options for commands and what
they do later.

The second command to learn will be the cd command, or "change
directory". To use it, you type cd followed by a space and the
directory name you wish to go into. In Linux, the top directory is /
(as opposed to C:\ in Windows). Let?s get there by using this command:

AvatharTri@localhost avathartri$ cd /
AvatharTri@localhost /$

Now, we are in the top directory. Use the ls command you learned
earlier to see everything that?s here. You should see several items,
which are directories. Now, let?s go into the home directory:

AvatharTri@localhost /$ cd home
AvatharTri@localhost home$

And you can now ls and see what?s around. In Linux there are some
special symbol shortcuts for specific folders. You can use these
symbols with cd, ls, or several other commands. The symbol ~ stands
for your home folder. One period . represents the directory your
currently in. Two periods .. represent the directory immediately above
your own. Here?s an example of the commands:

AvatharTri@localhost home$ cd ~
AvatharTri@localhost avathartri$

This moved us to our user?s personal directory.

AvatharTri@localhost avathartri$ cd .
AvatharTri@localhost avathartri$ cd ..
AvatharTri@localhost home$

The cd .. moved us up to the home directory.
As you?ve probably noticed by now, the section behind the prompt
changes as you change folders, although it might not always be the
case as it?s up to the personal configuration.

You can use these symbols with the ls command also to view what is in
different folders:

AvatharTri@localhost home$ ls ~
AvatharTri@localhost home$ ls ..

And you can view what is in a folder by specifying its path:

AvatharTri@localhost home$ ls /
AvatharTri@localhost home$ ls /home

The last command we will cover as far as finding your way around the
filesystem is the cat command. The cat command will show the contents
of a file. Find a file by using the cd and ls commands and then view
its contents with the cat command.

AvatharTri@localhost home$ cd [directory]
AvatharTri@localhost [directory]$ ls
AvatharTri@localhost [directory]$ cat [filename]

Where [directory] is the directory you want to view and [filename] is
the name of the file you want to view. Omit the brackets. Now, if the
file you viewed was a text file, you should see text, but if it wasn?t,
you might just see jumbled garbage, but this is ok. If the file goes
by too fast and goes off the screen, don?t worry, we will get to how
to scroll through it later.

One of the most useful commands is the man command, which displays the
"manual" for the command you want to know more about. To learn more
about the ls command:

AvatharTri@localhost home$ man ls

And you will see the manual page for ls. It displays the syntax, a
description, options, and other useful tidbits of information. Use the
up and down arrows to scroll and press q to exit. You can view the
manual pages for any command that has one (most commands do). Try this
out with all the commands that you know so far:

AvatharTri@localhost home$ man cd
AvatharTri@localhost home$ man cat
AvatharTri@localhost home$ man man

One very crucial option to the man command is the -k option. This will
search the descriptions of manual pages for the word you specify. You
can use this to find out what command to do what you need to do. For
example, let?s say we want to use a text editor:

AvatharTri@localhost home$ man -k editor

And you should see a list of apps with a short description and the
word "editor" in the description.

With a blank prompt, you can hit tab twice for Linux to display all
the possible commands. For Linux to display all the commands beginning
with a certain letter or series of letters, type those letters and hit
tab twice.

Note: This is actually a function of BASH and not Linux, but BASH is
the default Linux shell.

Now that you know a little about moving around the filesystem and
viewing manual pages, there is one more trick that we will cover to
help you out. Remember how the man pages were scrollable as in you
could use the arrow keys to scroll up and down? That is because the
man pages use something called the less pager. We?re not going to go
into what this does exactly and how it works, but that?s definitely
something that you will want to look up. Here?s how to use the less
pager with a file:

AvatharTri@localhost home$ cat [filename] | less

That uses something called a pipe. The line is the vertical line above
enter on your keyboard. Briefly, what this does is take the output
from the cat command, and stick it in the less pager. By doing this,
you can view files that would normally run off the screen and scroll
up and down.

Some final commands to check out:

mkdir - make directories
cp - copy file
mv - move file
rm - remove file
rmdir - remove directory
grep - search a file for a keyword
pwd - display current working directory
top - display system resources usage (kill the program with control + c)

How to copy songs from your iPod to your PC

2011-01-19T14:12:00.000+07:00

A reader points out a straightforward way for Windows users to transfer music from an iPod to your hard drive, without extra software:

Connect the iPod to your PC. If iTunes starts syncing (ie erasing) your music automatically, hit the X in the upper right hand corner of iTunes display, to the left of the search box, to stop it.
In Control Panel, Portable Media Devices, double-click your iPod.
Navigate to the Music folder.
Select all the music folders, and drag and drop them into a folder on your hard drive, or directly into iTunes.

And you’re done! The iPod music folder structure is strange and inexplicable, but once you move your files into iTunes you can set it to automatically organize your folder by artist and album to clean that up. (To do this, in iTunes Edit menu, choose Preferences and in the Advanced tab, check “Keep iTunes Music Folder organized.”)

If you give this a go, lemme know how it goes. I’ll ammend the instructions with any additional info for other versions of Windows and iPods.

Just for the record, I did not write this article, but I would have known how to do this. But one thing I ahve noticed is that you do not need to go into the control panel. Instead just make explorer.exe show hidden folders. Then, navigate into the iPod directory, go into iPod_control, and follow step four of the article. Software

Hard drive gone bad

2011-01-19T12:07:00.000+07:00

The most common problems originate
from corruption of the master boot record, FAT, or directory.
Those are soft problems which can usually be taken care of
with a combination of tools like Fdisk /mbr to refresh the
master boot record followed by a reboot and Norton disk doctor
or Spinneret.

The most common hardware problems are a bad controller, a bad
drive motor, or a bad head mechanism.

Can the BIOS see and identify the hard drive correctly? Ifit can't, then the hard drives onboard controller is bad.
Does the drive spin and maintain a constant velocity? If itdoes, that's good news. The motor is functioning.
If the drive surges and dies, the most likely cause is abad controller (assuming the drive is cool). A gate allowing the current to drive the motor may not be staying open. The drive needs a new controller.
Do you hear a lot of head clatter when the machine is turned on and initialized (but before the system attempts to access the hard drive). Head clatter would indicate that the spindle bearings are sloppy or worn badly. Maybe even lose and flopping around inside.
There is always the possibility that the controller you are using in the machine has gone south.

If the drive spins, try booting to the A> prompt, run Fdisk and check to see if Fdisk can see a partition on the hard drive. If Fdisk can see the partition, that means that it can access the drive and that the controller electronics are functioning correctly. If there is no head clatter, it may be just a matter of disk corruption which commonly occurs when a surge hits you machine and overwhelms the power supply voltage regulator. It commonly over whelms the system electronics allowing an EM pulse to wipe out the master boot record, file allocations table, and primary directory. Fdisk can fix the master boot record and Norton Disk Doctor can restore the FAT and Directory from the secondaries.
The drive spins but Fdisk can't see it. Try the drive in another system and repeat the test to confirm that Fdisk can'tread through the drives onboard controller. If it sees it in another system, then your machines hard drive interface is bad. You can try an upgraded or replacement controller card like a Promise or CMD Technologies (there are others) in you machine after disabling the integrated controller in the BIOS, but if the integrated controller went south, it may just be symptomatic of further failures and you'd be wise to replace the motherboard. Trying the drive in another machine also eliminates the variable that your machines 12 volt power output being bad.
If you get head clatter but a constant velocity on the drive motor (no surging), you might try sticking the hard drive in the freezer for about 12 hours. This is an old trick from back in the days of the FM/ESDI driver era. This can cause the drive components to shrink enough to make the track marker align with the tracks. We don't see that kind of platter spindle wear much anymore, but back in the old days, the balancing and bearings weren't as good. Still, under the right circumstances, it might help. It would heppend on how old the drive is and how many hours of wear have occurred. You have to be quick to get your info off the drive when it works.Back then, the drives were much smaller, so there wasn't so much to copy. So, go after the important data first.
The drive doesn't spin. Either the onboard controller is bad or the motor is bad (assuming you did try the drive in another machine). It's time to hit the net and local independent shops to see if you can locate another drive of the same make and model that's good. Since the drive is probably an older drive and no longer in distribution, your best bet is to find an identical used drive. If you know someone with the same make and model, you might be wise to try and persuade them to sell you their drive with an offer of providing them with a free upgraded drive. If you can locate an identical drive, start with the controller replacement ...this is the simplest and least invasive. If swapping the controller doesn't roduce the desire result, you can tear into the drive and swap the motors. While you have both drive opened up to accomplish this, scrutinize the platters, heads and armatures. You might even hook the drive up and power it from a system with both drives attached. This way, you could see anything that deviates between the actions of both drives when they are initialized. Swapping patters is unlikely to produce any positive result. They are a balanced system likethe tires on your car and I suspect that the balance will be different for each drive as will other variables.
There's always Ontrack Corp. who will attempt to recoup your info starting at $500 and going up from there. They don't fix and return the drive either.If the info is all that important to you, I would seek some professional and experience technician in your locality who makes his living from servicing and building computer systems... not just selling them. If you have had much experience salvaging information from bad hard drives, your likelihood of success is low. In the case of soft corruption, all utilities have their eccentricities. Often times, Norton Disk Doctor will go too far (if you let it). It's wise to just let those utilities small steps and then have a look at the drive and see if you can copy it off. Norton will go so far as to rename directories and files, and even delete them or break them up into fragments which are useless

Delete An "undeletable" File

2011-01-19T11:54:00.000+07:00

Open a Command Prompt window and leave it open.
Close all open programs.
Click Start, Run and enter TASKMGR.EXE
Go to the Processes tab and End Process on Explorer.exe.
Leave Task Manager open.
Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in.
At the command prompt type DEL <filename> where <filename> is the file you wish to delete.
Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.
Close Task Manager.

Or you can try this

Open Notepad.exe

Click File>Save As..>

locate the folder where ur undeletable file is

Choose 'All files' from the file type box

click once on the file u wanna delete so its name appears in the 'filename' box

put a " at the start and end of the filename
(the filename should have the extension of the undeletable file so it will overwrite it)

click save,

It should ask u to overwrite the existing file, choose yes and u can delete it as normal

Here's a manual way of doing it. I'll take this off once you put into your first post zain.

Start
Run
Type: command
To move into a directory type: cd c:\*** (The stars stand for your folder)
If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1
Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.

10 Fast and Free Security Enhancements

2011-01-19T11:52:00.000+07:00

.

Before you spend a dime on security, there are many precautions you can take that will protect you against the most common threats.

Check Windows Update and Office Update regularly (_http://office.microsoft.com/productupdates); have your Office CD ready. Windows Me, 2000, and XP users can configure automatic updates. Click on the Automatic Updates tab in the System control panel and choose the appropriate options.
Install a personal firewall. Both SyGate (_www.sygate.com) and ZoneAlarm (_www.zonelabs.com) offer free versions.
Install a free spyware blocker. Our Editors' Choice ("Spyware," April 22) was SpyBot Search & Destroy (_http://security.kolla.de). SpyBot is also paranoid and ruthless in hunting out tracking cookies.
Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger service (this is unrelated to the instant messaging program). Open Control Panel | Administrative Tools | Services and you'll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. Bye-bye, spam pop-ups! Any good firewall will also stop them.
Use strong passwords and change them periodically. Passwords should have at least seven characters; use letters and numbers and have at least one symbol. A decent example would be f8izKro@l. This will make it much harder for anyone to gain access to your accounts.
If you're using Outlook or Outlook Express, use the current version or one with the Outlook Security Update installed. The update and current versions patch numerous vulnerabilities.
Buy antivirus software and keep it up to date. If you're not willing to pay, try Grisoft AVG Free Edition (Grisoft Inc., w*w.grisoft.com). And doublecheck your AV with the free, online-only scanners available at w*w.pandasoftware.com/activescan and _http://housecall.trendmicro.com.
If you have a wireless network, turn on the security features: Use MAC filtering, turn off SSID broadcast, and even use WEP with the biggest key you can get. For more, check out our wireless section or see the expanded coverage in Your Unwired World in our next issue.
Join a respectable e-mail security list, such as the one found at our own Security Supersite at _http://security.ziffdavis.com, so that you learn about emerging threats quickly and can take proper precautions.
Be skeptical of things on the Internet. Don't assume that e-mail "From:" a particular person is actually from that person until you have further reason to believe it's that person. Don't assume that an attachment is what it says it is. Don't give out your password to anyone, even if that person claims to be from "support."

Windows Xp Tips 'n' Tricks, Windows XP Tips 'n' Tricks

2011-01-19T11:46:00.000+07:00

Please note that some of these tips require you to use a Registry Editor (regedit.exe), which could render your system unusable. Thus, none of these tips are supported in any way: Use them at your own risk. Also note that most of these tips will require you to be logged on with Administrative rights.

Unlocking WinXP's setupp.ini
============================

WinXP's setupp.ini controls how the CD acts. IE is it an OEM version or retail? First, find your setupp.ini file in the i386 directory on your WinXP CD. Open it up, it'll look something like this:

ExtraData=707A667567736F696F697911AE7E05
Pid=55034000

The Pid value is what we're interested in. What's there now looks like a standard default. There are special numbers that determine if it's a retail, oem, or volume license edition. First, we break down that number into two parts. The first five digits determines how the CD will behave, ie is it a retail cd that lets you clean install or upgrade, or an oem cd that only lets you perform a clean install? The last three digits determines what CD key it will accept. You are able to mix and match these values. For example you could make a WinXP cd that acted like a retail cd, yet accepted OEM keys.

Now, for the actual values. Remember the first and last values are interchangable, but usually you'd keep them as a pair:

Retail = 51882 335
Volume License = 51883 270
OEM = 82503 OEM

So if you wanted a retail CD that took retail keys, the last line of your setupp.ini file would read:

Pid=51882335

And if you wanted a retail CD that took OEM keys, you'd use:

Pid=51882OEM

How do I get the "Administrator" name on Welcome Screen?
========================================================

To get Admin account on the "Welcome Screen" as well as the other usernames, make sure that there are no accounts logged in.

Press "ctrl-alt-del" twice and you should be able to login as administrator!

finally worked for me after i found out that all accounts have to be logged out first

Fix Movie Inteferance in AVI files
==================================

If you have any AVI files that you saved in Windows 9x, which have interference when opened in Windows XP, there is an easy fix to get rid of the interference:

Open Windows Movie Maker.
Click View and then click Options.
Click in the box to remove the check mark beside Automatically create clips.

Now, import the movie file that has interference and drag it onto the timeline. Then save the movie, and during the rerendering, the interference will be removed.

Create a Password Reset Disk
============================

If you’re running Windows XP Professional as a local user in a workgroup environment, you can create a password reset disk to log onto your computer when you forget your password. To create the disk:

Click Start, click Control Panel, and then click User Accounts.
Click your account name.
Under Related Tasks, click Prevent a forgotten password.

Follow the directions in the Forgotten Password Wizard to create a password reset disk.

Store the disk in a secure location, because anyone using it can access your local user account

Change Web Page Font Size on the Fly
====================================

If your mouse contains a wheel for scrolling, you can change font size on the fly when viewing a Web page. To do so:

Press and hold Ctrl. Scroll down (or towards yourself) to enlarge the font size. Scroll up (or away from yourself) to reduce the font size.

You might find it useful to reduce font size when printing a Web page, so that you can fit more content on the page.

WinXP Clear Page file on shutdown
=================================

WINXPCPS.REG (WinXP Clear Page file on shutdown)

This Registration (.REG) file clears the Page file when you power off the computer.
Restart Windows for these changes to take effect!
ALWAYS BACKUP YOUR SYSTEM BEFORE MAKING ANY CHANGES!

Browse to: HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ Session Manager \ Memory Management

and add the DWORD variable "ClearPageFileAtShutdown"=dword:00000001

You can also do this without reg hacking.
Go to Control panel Administartative tools, local security policy. then goto local policies ---> security options.
Then change the option for "Shutdown: Clear Virtual Memory Pagefile"

Group Policy for Windows XP
===========================

One of the most full featured Windows XP configuration tools available is hidden right there in your system, but most people don't even know it exists. It's called the Local Group Policy Editor, or gpedit for short. To invoke this editor, select Start and then Run, then type the following:

gpedit.msc

After you hit ENTER, you'll be greeted by gpedit, which lets you modify virtually every feature in Windows XP without having to resort to regedit. Dig around and enjoy!

Forgetting What Your Files Are?
===============================

This procedure works under NTFS.

As times goes along you have a lot files on your computer. You are going to forget what they are. Well here is way to identify them as you scroll through Windows Explorer in the future.

This procedure works under NTFS.

1.. Open up a folder on your system that you want to keep track of the different files you might one to identify in the future.

2.. Under View make certain that you set it to the Details.

3.. Highlight the file you want to keep more information on. Right click the file and you will get a pop up menu. Click on properties.

4.. Click on the Summary Tab (make sure it says simple not advanced on the button in the box), You should now get the following fields,

Title,Subject, Author, Category, Keywords, Comments

You will see advanced also if you have changed it to simple, Here will be other fields you can fill in.

5.. Next you can fill in what ever field you want.

6.. After you finished click the apply button then OK.

7.. Next right click the bar above your files, under the address barand you should get a drop down menu. Here you can click the fields you want to display.

8.. You should now see a list with the new fields and any comments you have done.

9.. Now if you want to sort these just right click a blank spot and then you sort the information to your liking.

Temporarily Assign Yourself Administrative Permissions
======================================================

Many programs require you to have Administrative permissions to be able to install them. Here is an easy way to temporarily assign yourself Administrative permissions while you remain logged in as a normal user.

Hold down the Shift key as you right-click on the program’s setup file.

Click Run as.

Type in a username and password that have Administrative permissions.

This will also work on applications in the Start menu.

Create a Shortcut to Lock Your Computer
=======================================

Leaving your computer in a hurry but you don’t want to log off? You can double-click a shortcut on your desktop to quickly lock the keyboard and display without using CTRL+ALT+DEL or a screensaver.

To create a shortcut on your desktop to lock your computer:

Right-click the desktop.
Point to New, and then click Shortcut.

The Create Shortcut Wizard opens. In the text box, type the following:
rundll32.exe user32.dll,LockWorkStation

Click Next.

Enter a name for the shortcut. You can call it "Lock Workstation" or choose any name you like.

Click Finish.

You can also change the shortcut's icon (my personal favorite is the padlock icon in shell32.dll).

To change the icon:

Right click the shortcut and then select Properties.
Click the Shortcut tab, and then click the Change Icon button.

In the Look for icons in this file text box, type:
Shell32.dll.

Click OK.

Select one of the icons from the list and then click OK

You could also give it a shortcut keystroke such CTRL+ALT+L. This would save you only one keystroke from the normal command, but it could be more convenient.

Create a Shortcut to Start Remote Desktop
=========================================

Tip: You can add a shortcut to the desktop of your home computer to quickly start Remote Desktop and connect to your office computer.

To create a shortcut icon to start Remote Desktop

Click Start, point to More Programs, point to Accessories, point to Communications, and then click on Remote Desktop Connection.

Click Options.

Configure settings for the connection to your office computer.

Click Save As, and enter a name, such as Office Computer. Click Save.

Open the Remote Desktops folder.

Right-click on the file named Office Computer, and then click Create Shortcut.

Drag the shortcut onto the desktop of your home computer.

To start Remote Desktop and connect to your office computer, double-click on the shortcut

Instantly Activate a Screensaver
================================

Turn on a screensaver without having to wait by adding a shortcut to your desktop:

Click the Start button, and then click Search.
In the Search Companion window, click All file types.

In the file name box, type *.scr

In the Look in box, choose Local Hard Drives (C or the drive where you have system files stored on your computer.

Click Search.

You will see a list of screensavers in the results. Pick a screensaver you want. You can preview it by double-clicking it.

Right click on the file, choose Send To, and then click Desktop (create shortcut).

To activate the screensaver, double-click the icon on your desktop

Add a Map Drive Button to the Toolbar
=====================================

Do you want to quickly map a drive, but can’t find the toolbar button? If you map drives often, use one of these options to add a Map Drive button to the folder toolbar.

Option One (Long Term Fix)

Click Start, click My Computer, right-click the toolbar, then unlock the toolbars, if necessary.

Right-click the toolbar again, and then click Customize.

Under Available toolbar buttons, locate Map Drive, and drag it into the position you want on the right under Current toolbar buttons.

Click Close, click OK, and then click OK again.

You now have drive mapping buttons on your toolbar, so you can map drives from any folder window. To unmap drives, follow the above procedure, selecting Disconnect under Available toolbar buttons. To quickly map a drive, try this option.

Option Two (Quick Fix)

Click Start, and right-click My Computer.
Click Map Network Drive.

If you place your My Computer icon directly on the desktop, you can make this move in only two clicks!

Software not installing?
========================

If you have a piece of software that refuses to install because it says that you are not running Windows 2000 (such as the Win2K drivers for a Mustek scanner!!) you can simply edit HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/ProductName to say Microsoft Windows 2000 instead of XP and it will install. You may also have to edit the version number or build number, depending on how hard the program tries to verify that you are installing on the correct OS. I had to do this for my Mustek 600 CP scanner (compatibility mode didn''t help!!!) and it worked great, so I now have my scanner working with XP (and a tech at Mustek can now eat his words).

BTW, don''t forget to restore any changes you make after you get your software installed

You do this at your own risk.

Use your Windows Key
====================

The Windows logo key, located in the bottom row of most computer keyboards is a little-used treasure. Don''t ignore it. It is the shortcut anchor for the following commands:

Windows: Display the Start menu
Windows + D: Minimize or restore all windows
Windows + E: Display Windows Explorer
Windows + F: Display Search for files
Windows + Ctrl + F: Display Search for computer
Windows + F1: Display Help and Support Center
Windows + R: Display Run dialog box
Windows + break: Display System Properties dialog box
Windows + shift + M: Undo minimize all windows
Windows + L: Lock the workstation
Windows + U: Open Utility Manager
Windows + Q: Quick switching of users (Powertoys only)
Windows + Q: Hold Windows Key, then tap Q to scroll thru the different users on your pc

Change your cd key
==================

You don't need to re-install if you want to try the key out ... just do this:

1. Go to Activate Windows
2. Select the Telephone option
3. Click "Change Product Key"
4. Enter NOT ALLOWED ~ Zabref
5. Click "Update"

Now log off and log back in again. It should now show 60 days left, minus the number of days it had already counted down.

Note: If your crack de-activated REGWIZC.DLL and LICDLL.DLL, you are going to have to re-register them.

Remove the Shared Documents folders from My Computer
====================================================

One of the most annoying things about the new Windows XP user interface is that Microsoft saw fit to provide links to all of the Shared Documents folders on your system, right at the top of the My Computer window. I can't imagine why this would be the default, even in a shared PC environment at home, but what's even more annoying is that you cannot change this behavior through the sh*ll
: Those icons are stuck there and you have to live with it.
Until now, that is.

Simply fire up the Registry Editor and navigate to the following key:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ My Computer \ NameSpace \ DelegateFolders

You'll see a sub-key named {59031a47-3f72-44a7-89c5-5595fe6b30ee}. If you delete this, all of the Shared Documents folders (which are normally under the group called "Other Files Stored on This Computer" will be gone.

You do not need to reboot your system to see the change.

Before: A cluttered mess with icons no one will ever use (especially that orpaned one). After: Simplicity itself, and the way it should be by default.

This tip For older XP builds
===================

Edit or remove the "Comments" link in window title bars

During the Windows XP beta, Microsoft has added a "Comments?" hyperlink to the title bar of each window in the system so that beta testers can more easily send in a problem report about the user interface. But for most of us, this isn't an issue, and the Comments link is simply a visual distraction. And for many programs that alter the title bar, the Comments link renders the Minimize, Maximize, and Close window buttons unusable, so it's actually a problem.
Let's get rid of it. Or, if you're into this kind of thing, you can edit it too.

Open the Registry Editor and navigate to the following keys:
My Computer \ HKEY_CURRENT_USER \ Control Panel \ Desktop \ LameButtonEnabled
My Computer \ HKEY_CURRENT_USER \ Control Panel \ Desktop \ LameButtonText

The first key determines whether the link appears at all; change its value to 0 to turn it off. The second key lets you have a little fun with the hyperlink; you can change the text to anything you'd like, such as "Paul Thurrott" or whatever.

Editing either value requires a restart before the changes take effect.

Before: An unnecessary hyperlink. Have some fun with it! Or just remove it entirely. It's up to you.

Rip high-quality MP3s in Windows Media Player 8
================================================

The relationship between Windows Media Player 8 and the MP3 audio format is widely misunderstood. Basically, WMP8 will be able to playback MP3 files, but encoding (or "ripping" CD audio into MP3 format will require an MP3 plug-in. So during the Windows XP beta, Microsoft is supplying a sample MP3 plug-in for testing purposes, but it's limited to 56 Kbps rips, which is pretty useless. However, if you have an externally installed MP3 codec, you can use WMP8 to rip at higher bit rates. But you'll have to edit the Registry to make this work.
Fire up the Registry Editor and navigate to the following key:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ MediaPlayer \ Settings \ MP3Encoding

Here, you'll see sub-keys for LowRate and LowRateSample, which of course equates to the single 56 Kbps sample rate you see in WMP8. To get better sampling rates, try adding the following keys (Using New then DWORD value):

"LowRate" = DWORD value of 0000dac0
"MediumRate" = DWORD value of 0000fa00
"MediumHighRate" = DWORD value of 0001f400
"HighRate" = DWORD value of 0002ee00

Now, when you launch WMP8 and go into Tools, then Options, then Copy Music, you will have four encoding choices for MP3: 56 Kbps, 64 Kbps, 128 Kbps, and 192 Kbps. Note that you will not get higher bit rate encoding unless you have installed an MP3 codec separately; the version in Windows Media Player 8 is limited to 56 Kbps only.

Find the appropriate location in the Registry... ...add a few DWORD values... ...And then you'll be ripping CDs in higher-quality MP3 format!

Speed up the Start Menu
=======================

The default speed of the Start Menu is pretty slow, but you can fix that by editing a Registry Key. Fire up the Registry Editor and navigate to the following key:
HKEY_CURRENT_USER \ Control Panel \ Desktop \ MenuShowDelay

By default, the value is 400. Change this to a smaller value, such as 0, to speed it up.

Speed up the Start Menu (Part two)
==================================

If your confounded by the slow speed of the Start Menu, even after using the tip above, then you might try the following: Navigate to Display Properties then Appearance then Advanced and turn off the option titled Show menu shadow . You will get much better overall performance.

Speed up Internet Explorer 6 Favorites
======================================

For some reason, the Favorites menu in IE 6 seems to slow down dramatically sometimes--I've noticed this happens when you install Tweak UI 1.33, for example, and when you use the preview tip to speed up the Start menu. But here's a fix for the problem that does work, though it's unclear why:
Just open a command line window (Start button -> Run -> cmd) and type sfc, then hit ENTER. This command line runs the System File Checker, which performs a number of services, all of which are completely unrelated to IE 6. But there you go: It works.

Do an unattended installation
=============================

The Windows XP Setup routine is much nicer than that in Windows 2000 or Windows Me, but it's still an hour-long process that forces you to sit in front of your computer for an hour, answering dialog boxes and typing in product keys. But Windows XP picks up one of the more useful features from Windows 2000, the ability to do an unattended installation, so you can simply prepare a script that will answer all those dialogs for you and let you spend some quality time with your family.
I've written about Windows 2000 unattended installations and the process is pretty much identical on Windows XP, so please read that article carefully before proceeding. And you need to be aware that this feature is designed for a standalone Windows XP system: If you want to dual-boot Windows XP with another OS, you're going to have to go through the interactive Setup just like everyone else: An unattended install will wipe out your hard drive and install only Windows XP, usually.

To perform an unattended installation, you just need to work with the Setup Manager, which is located on the Windows XP CD-ROM in D:\SupportTools\DEPLOY.CAB by default: Extract the contents of this file and you'll find a number of useful tools and help files; the one we're interested in is named setupmgr.exe. This is a very simple wizard application that will walk you through the process of creating an answer file called winnt.sif that can be used to guide Windows XP Setup through the unattended installation.

One final tip: There's one thing that Setup Manager doesn't add: Your product key. However, you can add this to the unattend.txt file manually. Simply open the file in Notepad and add the following line under the [UserData] section:

ProductID=RK7J8-2PGYQ-P47VV-V6PMB-F6XPQ

(This is a 60 day cd key)

Then, just copy winnt.sif to a floppy, put your Windows XP CD-ROM in the CD drive, and reboot: When the CD auto-boots, it will look for the unattend.txt file in A: automatically, and use it to answer the Setup questions if it's there.

Finally, please remember that this will wipe out your system! Back up first, and spend some time with the help files in DEPLOY.CAB before proceeding.

For Older builds or not using setupreg.hiv file
===============================================

Remove the Desktop version text

During the Windows XP beta, you will see text in the lower right corner of the screen that says Windows XP Professional, Evaluation Copy. Build 2462 or similar. A lot of people would like to remove this text for some reason, and while it's possible to do so, the cure is more damaging than the problem, in my opinion. So the following step will remove this text, but you'll lose a lot of the nice graphical effects that come in Windows XP, such as the see-through icon text.

To remove the desktop version text, open Display Properties (right-click the desktop, then choose Properties) and navigate to the Desktop page. Click Customize Desktop and then choose the Web page in the resulting dialog. On this page, check the option titled Lock desktop items. Click OK to close the dialog, and then OK to close Display Properties. The text disappears. But now the rest of your system is really ugly. You can reverse the process by unchecking Lock desktop items.

There's also a shortcut for this process: Just right-click the desktop and choose Arrange by then Lock Web Icons on the Desktop.

--------------------------------------------------------------------------------
Enable ClearType on the Welcome Screen!
=======================================

As laptop users and other LCD owners are quickly realizing, Microsoft's ClearType technology in Windows XP really makes a big difference for readability. But the this feature is enabled on a per-user basis in Windows XP, so you can't see the effect on the Welcome screen; it only appears after you logon.

But you can fix that. Fire up the Registry Editor and look for the following keys:

(default user) HKEY_USERS \ .Default \ Control Panel \ Desktop \ FontSmoothing (String Value)
HKEY_USERS \ .Default \ Control Panel \ Desktop \ FontSmoothingType (Hexadecimal DWORD Value)

Make sure both of these values are set to 2 and you'll have ClearType enabled on the Welcome screen and on each new user by default.

Stop Windows Messenger from Auto-Starting
=========================================

If you're not a big fan of Windows Messenger simply delete the following Registry Key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\MSMSGS

Display Hibernate Option on the Shut Down dialog
================================================

For some reason, Hibernate may not be available from the default Shut Down dialog. But you can enable it simply enough, by holding down the SHIFT key while the dialog is visible. Now you see it, now you don't!

Add album art to any music folder
=================================

One of the coolest new features in Windows XP is its album thumbnail generator, which automatically places the appropriate album cover art on the folder to which you are copying music (generally in WMA format). But what about those people that have already copied their CDs to the hard drive using MP3 format? You can download album cover art from sites such as cdnow.com or amguide.com, and then use the new Windows XP folder customize feature to display the proper image for each folder. But this takes time--you have to manually edit the folder properties for every single folder--and you will lose customizations if you have to reinstall the OS. There's an excellent fix, however.

When you download the album cover art from the Web, just save the images as folder.jpg each time and place them in the appropriate folder. Then, Windows XP will automatically use that image as the thumbnail for that folder and, best of all, will use that image in Windows Media Player for Windows XP (MPXP) if you choose to display album cover art instead of a visualization. And the folder customization is automatic, so it survives an OS reinstallation as well. Your music folders never looked so good!

Album cover art makes music folder thumbnails look better than ever!

Change the location of the My Music or My Pictures folders
==========================================================

In Windows 2000, Microsoft added the ability to right-click the My Documents folder and choose a new location for that folder in the sh*ll
. With Windows XP, Microsoft has elevated the My Music and My Pictures folders to the same "special sh*ll
folder" status of My Documents, but they never added a similar (and simple) method for changing those folder's locations. However, it is actually pretty easy to change the location of these folders, using the following method.

Open a My Computer window and navigate to the location where you'd like My Music (or My Pictures) to reside. Then, open the My Documents folder in a different window. Drag the My Music (or My Pictures) folder to the other window, and Windows XP will update all of the references to that folder to the new location, including the Start menu.

Or use Tweak UI

Add/Remove optional features of Windows XP
==========================================

To dramatically expand the list of applications you can remove from Windows XP after installation, navigate to C:\WINDOWS\inf (substituting the correct drive letter for your version of Windows) and open the sysoc.inf file. Under Windows XP Professional Edition RC1, this file will resemble the following by default:

[Version] Signature = "$Windows NT$"
DriverVer=06/26/2001,5.1.2505.0

[Components]
NtComponents=ntoc.dll,NtOcSetupProc,,4

MSWordPad=ocgen.dll,OcEntry,wordpad.inf,HIDE,7
ZoneGames=zoneoc.dll,ZoneSetupProc,igames.inf,,7

[Global]
WindowTitle=%WindowTitle%
WindowTitle.StandAlone="*"

The entries that include the text hide or HIDE will not show up in Add/Remove Windows Components by default. To fix this, do a global search and replace for ,hide and change each instance of this to , (a comma). Then, save the file, relaunch Add/Remove Windows Components, and tweak the installed applications to your heart's content.

Cool, eh? There are even more new options now under "Accessories and Utilities" too.

Remove Windows Messenger
========================

It seems that a lot of people are interested in removing Windows Messenger for some reason, though I strongly recommend against this: In Windows XP, Windows Messenger will be the hub of your connection to the .NET world, and now that this feature is part of Windows, I think we're going to see a lot of .NET Passport-enabled Web sites appearing as well. But if you can't stand the little app, there are a couple of ways to get rid of it, and ensure that it doesn't pop up every time you boot into XP. The best way simply utilizes the previous tip:

If you'd like Windows Messenger to show up in the list of programs you can add and remove from Windows, navigate to C:\WINDOWS\inf (substituting the correct drive letter for your version of Windows) and open sysoc.inf (see the previous tip for more information about this file). You'll see a line that reads:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7

Change this to the following and Windows Messenger will appear in Add or Remove Programs, then Add/Remove Windows Components, then , and you can remove it for good:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,7

Cisco Router Configuration Tutorial

2011-01-19T11:31:00.000+07:00

Cisco Inter-network Operating System:

Cisco IOS Modes of Operation
The Cisco IOS software provides access to several different command modes. Each command mode provides a different group of related commands.
For security purposes, the Cisco IOS software provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
The following table describes some of the most commonly used modes, how to enter the modes, and the resulting prompts. The prompt helps you identify which mode you are in and, therefore, which commands are available to you
Mode of Operation
Usage
How to Enter the Mode
Prompt
User EXEC
Change terminal settings on a temporary basis, perform basic tests, and list system information.
First level accessed.
Router>
Privileged EXEC
System administration, set operating parameters.
From user EXEC mode, enter enable password command
Router#
Global Config
Modify configuration that affect the system as a whole.
From privileged EXEC, enter configure terminal.
Router(config)#
Interface Config
Modify the operation of an interface.
From global mode, enter interface type number.
Router(config-if)#
Setup
Create the initial configuration.
From privileged EXEC mode, enter command setup.
Prompted dialog
User EXEC Mode:
When you are connected to the router, you are started in user EXEC mode. The user EXEC commands are a subset of the privileged EXEC commands.
Privileged EXEC Mode:
Privileged commands include the following:

Configure – Changes the software configuration.
Debug – Display process and hardware event messages.
Setup – Enter configuration information at the prompts.

Enter the command disable to exit from the privileged EXEC mode and return to user EXEC mode.
Configuration Mode
Configuration mode has a set of submodes that you use for modifying interface settings, routing protocol settings, line settings, and so forth. Use caution with configuration mode because all changes you enter take effect immediately.
To enter configuration mode, enter the command configure terminal and exit by pressing Ctrl-Z.
Note:
Almost every configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. For example, IP routing is enabled by default. To disable IP routing, enter the no ip routing command and enter ip routing to re-enable it.
Getting Help
In any command mode, you can get a list of available commands by entering a question mark (?).
Router>?
To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?).
Router#co?
configure connect copy
To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark.
Router#configure ?
memory Configure from NV memory
network Configure from a TFTP network host
terminal Configure from the terminal
You can also abbreviate commands and keywords by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the show command to sh.
Configuration Files
Any time you make changes to the router configuration, you must save the changes to memory because if you do not they will be lost if there is a system reload or power outage. There are two types of configuration files: the running (current operating) configuration and the startup configuration.
Use the following privileged mode commands to work with configuration files.

configure terminal – modify the running configuration manually from the terminal.
show running-config – display the running configuration.
show startup-config – display the startup configuration.
copy running-config startup-config – copy the running configuration to the startup configuration.
copy startup-config running-config – copy the startup configuration to the running configuration.
erase startup-config – erase the startup-configuration in NVRAM.
copy tftp running-config – load a configuration file stored on a Trivial File Transfer Protocol (TFTP) server into the running configuration.
copy running-config tftp – store the running configuration on a TFTP server.

IP Address Configuration
Take the following steps to configure the IP address of an interface.
Step 1: Enter privileged EXEC mode:
Router>enable password
Step 2: Enter the configure terminal command to enter global configuration mode.
Router#config terminal
Step 3: Enter the interface type slot/port (for Cisco 7000 series) or interface type port (for Cisco 2500 series) to enter the interface configuration mode.
Example:
Router (config)#interface ethernet 0/1
Step 4: Enter the IP address and subnet mask of the interface using the ip address ipaddress subnetmask command.
Example,
Router (config-if)#ip address 192.168.10.1 255.255.255.0
Step 5: Exit the configuration mode by pressing Ctrl-Z
Router(config-if)#[Ctrl-Z]
Routing Protocol Configuration
Routing Information Protocol (RIP)
Step 1: Enter privileged EXEC mode:
Router>enable password
Step 2: Enter the configure terminal command to enter global configuration mode.
Router#config terminal
Step 3: Enter the router rip command
Router(config)#router rip
Step 4: Add the network number to use RIP and repeat this step for all the numbers.
Router(config-router)#network network-number
Example: Router(config-router)#network 192.168.10.0
Note: To turn off RIP, use the no router rip command.
Router(config)#no router rip
Other useful commands

Specify a RIP Version

By default, the software receives RIP version 1 and version 2 packets, but sends only version 1 packets. To control which RIP version an interface sends, use one of the following commands in interface configuration mode:
Command
Purpose
ip rip send version 1
Configure an interface to send only RIP version 1 packets.
ip rip send version 2
Configure an interface to send only RIP version 2 packets.
ip rip send version 1 2
Configure an interface to send only RIP version 1 and version 2 packets.
To control how packets received from an interface are processed, use one of the following commands:
Command
Purpose
ip rip receive version 1
Configure an interface to accept only RIP version 1 packets.
ip rip receive version 2
Configure an interface to accept only RIP version 2 packets
ip rip receive version 1 2
Configure an interface to accept only RIP version 1 or 2 packets.

Enable or Disable Split Horizon

Use one of the following commands in interface configuration mode:
Command
Purpose
ip split-horizon
Enable split horizon.
no ip split-horizon
Disable split horizon.
Open Shortest Path First (OSPF)
Step 1: Enter privileged EXEC mode:
Router>enable password
Step 2: Enter the configure terminal command to enter global configuration mode.
Router#config terminal
Step 3: Enter the router ospf command and follow by the process-id.
Router(config)#router ospf process-id
Pick the process-id which is not being used. To determine what ids are being used, issue the show process command.
Router(config)#show process
Step 4: Add the network number, mask and area-id
Router(config-router)#network network-number mask area area-id
The network-number identifies the network using OSPF. The mask tells which bits to use from the network-number, and the area-id is used for determining areas in an OSPF configuration.
Example:
Router(config-router)#network 192.168.10.0 255.255.255.0 area 0.0.0.0
Repeat this step for all the network numbers.
To turn off OSPF, use the following command.
Router(config)#no router ospf process-id

Other useful commands

Configure OSPF Interface Parameters

You are not required to alter any of these parameters, but some interface parameters must be consistent across all routers in an attached network.
In interface configuration mode, specify any of the following:
Command
Purpose
ip ospf cost cost
Explicitly specify the cost of sending a packet on an OSPF interface.
ip ospf retransmit-interval seconds
Specify the number of seconds between link state advertisement retransmissions for adjacencies belonging to an OSPF interface.
ip ospf transmit-delay seconds
Set the estimated number of seconds it takes to transmit a link state update packet on an OSPF interface.
ip ospf priority number
Set router priority to help determine the OSPF designated router for a network.
ip ospf hello-interval seconds
Specify the length of time, in seconds, between the hello packets that a router sends on an OSPF interface.
ip ospf dead-interval seconds
Set the number of seconds that a router’s hello packets must not have been seen before its neighbors declare the OSPF router down.
ip ospf authentication-key password
Assign a specific password to be used by neighboring OSPF routers on a network segment that is using OSPF’s simple password authentication.

Interior Gateway Routing Protocol (IGRP)

Create the IGRP Routing Process

To create the IGRP routing process, use the following required commands starting in global configuration mode.
Step
Command
Purpose

router igrp autonomous-system enable an IGRP routing process, which place you in router configuration mode.
network network-number Associate networks with an IGRP routing process.

Disable Holddown

The holddown mechanism is used to help avoid routing loop in the network, but has the effect of increasing the topology convergence time.
To disable holddowns with IGRP, use the following command in router configuration mode. All devices in an IGRP autonomous system must be consistent in their use of holddowns.
Command
Purpose
No metric holddown
Disable the IGRP holddown period.

Enforce a Maximum Network Diameter

Define a maximum diameter to the IGRP network. Routes whose hop counts exceed this diameter are not advertised. The default maximum diameter is 100 hops. The maximum diameter is 255 hops.
Use the following command in router configuration mode.
Command
Purpose
metric maximum-hops hops

Configure the maximum network diameter.

To turn off IGRP, use the following command.

Router(config)#no router igrp autonomous-system
Border Gateway Protocol (BGP)

Enable BGP Routing

Use the following commands in global configuration mode.
Step
Command
Purpose

router bgp autonomous-system enable a BGP routing process, which places you in router configuration mode.
network network-number [mask network-mask] [route-map route-map-name]

Flag a network as local to this autonomous system and enter it to the BGP table.

Configure BGP Neighbors

BGP must completely understand the relationships it has with its neighbors.
Command
Purpose
neighbor {ip-address | peer-group-name} remote-as number
Specify a BGP neighbor.

Reset BGP Connections

Use either of the following commands in EXEC mode to reset BGP connections
Command
Purpose
clear ip bgp address
Reset a particular BGP connection.
clear ip bgp *
Reset all BGP connections.

To turn off BGP, use the following command.

Router(config)#no router bgp autonomous-system
How to read router/link status
Status of router and links can be easily determined by power LED of router and link LED of each interface (if any). However, you may find a transceiver connected to an AUI port looks like the following:
When this transceiver is correctly connected, the “POWER” LED should light. Similarly, the “LINK” and “POLARITY” LEDs should light when you inserted the cable into the RJ45 socket on the transceiver. (Note that to get this result; the other end of the cable should be connected to some other devices as well.) If these LEDs are not light, you probably have problems with the link (cable).
