Basic Linux Commands List

2012-12-13T12:19:00.000-08:00

The purpose of this blog entry is to document a few basic Linux commands that i find useful. I'm fairly new to Linux and recording these commands gives me a point of reference and helps me remember them.

It's important to note that in Linux syntax is case sensitive.

I am using Ubuntu so my syntax may differ slightly to yours if you are using another distro. If you want to learn more about any of the commands i list try the following:

man command (e.g man ls)

or

command -h

or

command --help

The sections i have added so far are:

1. Users
2. Navigation
3. Files
4. Networking
5. Hardware
6. System Tools

I will add to this document as i learn more commands.

1. Users

To add a new user called bob:

adduser bob

To switch to a new user called bob:

su bob

To change bobs password:

passwd bob

To switch straight to root:

su

To run a command as root whilst logged in as another user:

sudo command

* this assumes you are in the sudo group.

To view which user you are currently logged in as use:

whoami

2. Navigation

To list directories use:

ls

To list all directories including hidden and permissions use:

ls -la

To list all directories in another folder use the following syntax:

ls -la /home/bob/

In the output anything preceded with a . is hidden.

To change directory use:

cd directory_name

Or the path:

cd /etc/directory_name

To move back in the directory structure use:

cd ..

or

cd ../..

To navigate directly to the root / directory:

cd /

To navigate directly to your home directory:

cd #

To print the current directory use:

pwd

3. Files

To view the contents of a file:

cat filename.txt

To delete a file:

rm filename.txt

To delete all files and directories and sub-directories (without prompting)

rm -Rf directory_name

To locate a file:

locate filename.txt

To change the owner of a file use:

chown bob filename.txt

To change the group ownership as well use:

chown bob:users_group filename.txt

To create a directory use:

mkdir mydirectory

To create a file use:

touch myfilename

To move or rename a file use:

mv file1 file2
To copy a file to bobs home directory use:

cp file1 /home/bob/

4. Networking

To obtain a DHCP address (on all interfaces):

dhclient

Or on just one particular interface:

dhclient eth1
To view the interface network properties:

ifconfig

To set the IP address of a interface:

ifconfig eth1 192.168.1.100/24

To change the MAC address of an interface:

ifconfig eth1 hw ether 11:22:33:44:55:66:77:00

To put an interface into promiscuous mode:
ifconfig eth1 promisc

To take an interface out of promiscuous mode:

ifconfig eth1 -promisc
To view the wireless interface settings:

iwconfig

To set the wireless interface to a particular wireless AP:

iwconfig eth1 essid my_wireless_network

To set the wireless interface to managed mode:

iwconfig eth1 mode managed

To set a wireless interface to monitor mode (for sniffing etc..)

iwconfig eth1 mode monitor

To configure WEP encryption on a wireless interface:

iwconfig eth1 enc {enc key}

To configure a wireless interface to use a particular channel:
iwconfig eth1 channel 3
To view the routing table:

route

To view the routing cache:

route -C
To set a static route to a network:

route add -net 172.16.1.1 netmask 255.255.0.0 dev eth1

To set a static route to a host:

route add -host 80.127.23.65 eth1

To delete a route:

route del -host 80.127.23.65 eth1
To add a default gateway of 192.168.1.1:

route add default gw 192.168.1.1

Tracerouting in linux uses UDP packets as oppose to Windows using ICMP.

To traceroute to a target (yahoo in my example) use:

traceroute www.yahoo.com

Another really cool program i found on my system for tracerouting and providing really useful diagnostic info is mtr:

mtr www.yahoo.com

Bear in mind that unlike traceroute mtr use ICMP echo requests.

To list all network connection (external):

netstat -punta

To list network statistics:

netstat -s

To list statistics on an interface:

netstat -i eth1

For a continuous listing on any netstat commands add -c to the command:

netstat -punta -c

To list any IPTables rules:

iptables -L -v

To quickly add a rule to drop ICMP requests:

iptables -A OUTPUT -p icmp -d 0/0 -j DROP

The above command appends (-A) a rule to the output (OUTPUT) chain telling it that ICMP (-p ICMP) from any destination (-d 0/0) should be dropped (-j DROP)

To remove your rule you can use the command:

iptables -F OUTPUT

To flush all rules use:

iptables -F

To remove any currently active rules:

iptables -X

The following rules can be used to rate limit connections to prevent brute-force login to port 21 (for FTP)
iptables -I INPUT -p tcp --dport 21 -i eth1 -m state --state NEW -m recent \

  --set

iptables -I INPUT -p tcp --dport 21 -i eth1 -m state --state NEW -m recent \
 --update --seconds 60 --hitcount 4 -j DROP

Using the rule above will drop any more than 3 connection attampts in 60 seconds from the same IP address.

(I will post a blog article on iptables rules)

Or to block icmp you could run or script the following command:

echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all

The default is 0, to to revert it back use:

echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all

To use a capture network traffic:

ifconfig eth1 promisc
tcpdump -i eth1 -vv

All the above commands assume the interface is eth1. If you are unsure which is your wireless interface run iwconfig and look for the interface with the wireless extensions.

5. Hardware

To list installed hardware (available on ubuntu):

lshw

To list all PCI devices:

lspci

To list all USB devices:

lsusb

To list the loaded modules

lsmod

Another useful trick i have found relating to hardware, is when i attach a new USB HDD and i am unsure of the what it will be called, i attach the device and then immediately look at /var/log/messages for the last entries. This usually gives me what i need. The tail command is useful here.

tail -n 10 /var/log/messages

This will display the last 10 lines of the log file.

To use tail and have it update (-s 2 will update every 2 seconds) as the log updates use the following command:

tail -n 10 -s 2 -f /var/log/messages

Running the dmesg command will also reveal useful information about hardware.

6. System Tools

To view free disk space use:

df -h

To view disk usage on the system use:

du

du can also specify a directory:

du /home/bob/

A useful tool for viewing running processes is top:

top

or for a more interactive version:

htop

You can also use ps to view process information.

To view a list of all running processes:
ps aux

To view a list of processes by a particular user (bob):
ps U bob

To view process in a tree:

ps -eH

To kill a process by it's PID (example of 28556):

kill 28556

Mounting Disks

To view a list of currently mounted file systems view /etc/mtab or use:

mount -L

To mount a disk first create a folder which you will mount it to:
mkdir /media/usb

mount - t ntfs /dev/sdb /media/usb

To unmount a disk:

umount /media/usb

SSH Tunnel

2012-12-13T12:16:00.002-08:00

SSH Tunneling

This is a quick blog post to let my mate Ollie know about a few ways that I use SSH and how it is useful.

Firstly, a SSH client connects to a SSH server, logs in with either a password or certificate and communicates over an encrypted tunnel. The beauty of SSH is that it is also easy to tunnel other types of traffic such as HTTP or VNC over the tunnel. This is useful for the following:

> Secure Administration of a remote server.
> Secure File transfer.
> Securing web traffic over a non-secure wired or wireless network.
> Bypassing of restrictions and filtering imposed on the local network.

Tools

> Privoxy
> SSH
> Screen

Setup

At home I have installed SSH on a server and started the service (/etc/init.d/ssh start) listening on port 22 for SSH traffic. I have set port forwarding up on my firewall to allow traffic to hit the server on this port. Usually I will set up a non-standard port but for the sake of an easy explanation I'll leave it at port 22.

On that server I have also installed pivoxy (apt-get install privoxy), and started it (/etc/init.d/privoxy start). By default, Privoxy binds to 127.0.0.1:8118 , and I have also installed Screen. Screen is a program that allows you to have multiple terminal sessions open at once and leave them running after disconnecting from the SSH server.

Connecting To The Server

From my client I connect to the server by using the following command:

ssh synjunkie@ssh_server_ipaddress

After logging in I can issue commands as if I'm sitting at the server. After connecting I would start Screen by issuing the `screen` command. If I wanted to connect to a previous screen session I would use `screen -r`

You navigate through Screen by issuing commands through key-bindings. A few of the ones I find most useful are:

Ctrl+a c new window
Ctrl+a n next window
Ctrl+a p previous window
Ctrl+a " select window from list
Ctrl+a A set window title
Ctrl+a ? show key bindings/command names
Ctrl+a d detach screen from terminal

Screen is great because you can leave a scan going in one session, irc in another and say a traffic capture in another.

Tunneling Traffic

as well as connecting to the server I might want to tunnel some traffic over SSH to my home server and then back out.

For this I would issue the following command on my client and log in.

ssh -NL 8118:localhost:8118 synjunkie@ssh_server_ipaddress

After setting up the tunnel I would go into the proxy settings on my browser and point them to localhost port 8118.

I hope this illustrates a couple of good uses for SSH.

SSH Tunneling Full Tutorial

SSH Tunneling the Pretty Way

This is just a quick post about a nice little tool I found that allows you to setup and save your SSH tunnels and then quickly bring them up when required. Why might you want to do this? Well theres plenty of reasons. They range from it feels geeky, to you're paranoid about those kids in the coffee shop with the "Hack Naked" stickers on there laptops, to just because you can.

Now this guide does assume that you have a SSH server that you can get too and its running Privoxy on port 8118.

The tool is Gnome SSH Tunnel Manager (gSTM) and is available from http://gstm.sourceforge.net the repositories.

apt-get install gstm

Now, a quick reminder of the manual way:

ssh -NL 8118:localhost:8118 synjunkie@ssh_server_ipaddress

Then point your browsers proxy at localhost:8118

And now the pretty way.

Create The Tunnel

Open gSTM from Applications > Internet Menu, and enter your SSH server details. Click Add to configure the port redirection settings and click OK.

Save the settings by clicking OK.

Now you have a tunnel that is saved for you and can be started by Clicking on the Start Button.

Configure The Browser

Now you need to tell Firefox to use your tunnel. Open Firefox Preferences from the Edit menu in Firefox and amend the network proxy settings.

Now you can safely browse the web

You could make this even more seamless by adding a Firefox extension to allow you to have multiple proxy configurations set up and simply select which one you want using drop down list on the toolbar. Switch Proxy works well for this.

Check The Tunnel

You can test that your traffic is being tunneled by using Netstat, Etherape, TCPDump or a number of other tools. Bellow I have used Netstat.

I can see that I am making connections to local port 8118 and that the only external web traffic is going to my SSH server.

When I used Etherape to check my traffic I saw that DNS was not tunneled so one thing to bear in mind is that if your attacker is using subverting your DNS, The whole tunnel will not work. Which I guess is better than it working and your data being stolen!

Free ICMP Tunnel

2012-12-13T12:10:00.002-08:00

On the computer network a person feels himself not comfortable with all those security measures implemented (firewalls, proxy servers, Router Access lists…), these measures are very important to protect users but even if all these perimeters are installed we can have a good opportunity to eliminate and bypass them.
Usually there are some standard protocol that are allowed on any network (HTTP/HTTPS, SMTP, POP…) and even for these protocols traffic do not directly go to outside network but it passes by NAT over getaways that will scan and block non legitimate packets.
ICMP protocol has been used by system administrators to send error messages—indicating, for instance, that a requested service is not available or that a host or router could not be reached and while ICMP is required and do not cause a big threat from the security prospective you can find it enabled on most network.

Now there are many programs that allows user to create ICMP Tunnel for having a full access to internet such as (Simple ICMP tunnel, ICMP Shell and PingTunnel), the concept of ICMP tunneling works by injecting arbitrary data into an echo packet sent to a remote computer. The remote computer replies in the same manner, injecting an answer into another ICMP packet and sending it back as a result client performs all communication using ICMP echo request packets.
What I suggest is to use Ping tunnel (Ptunnel) by Daniel Stodle which provides the following functionality:
* Tunnel TCP using ICMP echo request and reply packets
* Connection are reliable
* Handles multiple connection
* Acceptable bandwidth (150 kb/s downstream and about 50 kb/s upstream)
* Authentication to prevent others from using the proxy.

You will need to have 2 machines that runs ptunnel one Client and the second is the ICMP proxy server, On the client:
# ./ptunnel -p -lp -da -dp [-c ] [-v ] [-f ] [-u] [-x password]
On the proxy server:
# ./ptunnel [-c ] [-v ] [-f ] [-u] [-x password]
For Example:
# ./ptunnel -p 192.168.X.X -lp 4567 -da HomeserverIP -dp 80
Do not forget to configure your proxy browser settings to localhost on port 4567 and set the password on both side for authentication. you can use ptunnel for other TCP protocols such as SSH or pop the most important is to change the port value accordingly.The only negative point by using ICMP tunneling that bandwidth are not perfect but acceptable.

Google Maps for iOS Download Now

2012-12-13T12:05:00.001-08:00

To say that Apple Maps for iOS 6 has been a blunder is quite the understatement. Ever since iOS 6 was released to the public a few months ago, complaints began rolling out about the mapping services. Everything from misplaced roads, to wonky directions, to horrible rendering of terrain became fodder for the online media and even mainstream media -- not to mention Apple's customers and Apple's competitors.

Things got so bad that Apple CEO Tim Cook even apologized to Apple customers

However, even as Apple is looking to improve its native Maps application on a continuing basis, Google is looking to offers users a seasoned alternative -- Google Maps. The refreshed Google Maps app for iOS has all the goodies (and more) that users loved before Apple decided to give the application the boot for its own homegrown solution.

Street View, transit directions, walking directions, traffic data, and restaurant reviews (provided by Zagat) are all included. And in case you were wondering, yes, turn-by-turn navigation is front in center in the new Google Maps iOS app.

For users of Android smartphones, none of this stuff is really news to you -- you've been enjoying such functionality for years. However, for Apple customers that have complained about Apple's native Maps app, you now can install an alternative that appears to be better in nearly every way.

Samsung Exec Praises Apple Ecosystem, Uses iPhone and iPad at Home

2012-12-13T12:03:00.002-08:00

Samsung exec shows Apple some love

Samsung and Apple definitely have an awkward relationship. Samsung is one of Apple's top suppliers for components in its popular iPad and iPhone mobile devices. However, Apple is currently embroiled in a bitter "thermonuclear war" with Samsung over claims that the South Korean electronics giant has ripped of its patented designs and technology.

Despite the fact that Apple is looking to have numerous Samsung products banned from the market, it was revealed that Samsung President and Chief Strategy Officer Young Sohn actually has quite a bit of love for Apple and its products in an interview with MIT Technology Review. Sohn praised Apple tie-ins like iCloud, stating, "If you look at the strengths of Apple, in a way it’s not the product per se. It’s that consumers like their ecosystem such as iCloud. I like that my family 6,000 miles away in Korea is able to see my schedule and see all of my contacts and photos."

Sohn went on to state that he not only uses a Mac at home, but he also has an iPhone and an iPad. Being that Sohn is a high-ranking executive at Samsung, he naturally also owns a Samsung Galaxy smartphone (Sohn joined Samsung in August, so we can only assume that he's sporting a Galaxy S III).

Puzzled by the admission of a person in his position using Apple products, interviewer Jessica Laber asked for an explanation. Sohn responded:

At work I’m using Samsung devices; Apple at home, mainly because all of my systems and files are done that way. That’s sticky, you know? However, I did figure out how to sync all of my contacts and all of my schedules between the two different systems. You can do it. It’s a bit of work, but it is possible.

We're sure that the top brass at Samsung aren't exactly thrilled that Sohn is extolling his love for Apple products in an interview, especially considering that the company makes comparable devices to all of the ones that he uses at home. But it's nice to see a high-level exec keeping an open mind about the competition.

iPhone 5 Full Review

2012-12-13T12:01:00.001-08:00

The last significant redesign of the iPhone platform came in 2010 with the iPhone 4. It was an update that literally touched all aspects of the device, from SoC to display to baseband and of course, chassis. Last month’s launch of the iPhone 5 is no different in magnitude. The sixth generation iPhone makes some of the biggest changes to the platform since its introduction in 2007.
Visually the device begins by evolving the design language of the iPhone 4/4S chassis. From the launch of the iPhone 4 it was quite obvious that Apple had picked a design it was quite proud of. Thus it’s not too surprising that, from a distance, the iPhone 5 resembles the previous two iPhone models. We’ll get into material differences shortly, but what make the iPhone 5 design such a radical departure is its larger display.
All previous iPhones have maintained the same 3.5-inch, 3:2 aspect ratio display. With the rest of the world quickly moving to much larger displays, and with 16:9 the clear aspect ratio of choice, when faced with the decision of modernizing the iPhone platform the choice was obvious.

The iPhone 5 embraces a taller, 4-inch, 16:9 1136 x 640 display opting to lengthen the device instead of increasing its area in both dimensions. The result is a device that is distinctly an iPhone, albeit a modern one. The taller display doesn’t do much to make desktop web pages any easier to read as a result of the width staying the same. Those longing for an HTC One X or Galaxy S 3 sized device running iOS are out of luck. Reading emails and typing are both improved though as there’s now more room for lists and the keyboard no longer occupies as much of the display. The taller device can be more awkward to use if you have smaller hands, but the added screen real estate is honestly worth it. Once you get used to the iPhone 5’s display, going back to the older models is tough.
The taller chassis went on a diet as well. The iPhone 5 is now considerably thinner and lighter than its predecessor, which is yet another factor that contributes to it feeling more modern.

Internally the device changes are just as significant, if not more, than those on the outside. The iPhone 5 includes LTE support, which in areas where LTE networks are deployed can be enough reason alone to warrant an upgrade.
The iPhone 5 also includes a brand new SoC from Apple: the A6. For the first time since the introduction of the iPad, Apple has introduced a major branded SoC on an iPhone first. The iPhone 4 used the A4 after it debuted on the iPad, and the 4S picked up the A5 months after the iPad 2 launched with it. The A6 however arrives first on the iPhone 5, and with it comes two of Apple’s first, custom designed CPU cores. We’ve always known Apple as a vertically integrated device and software vendor, but getting into CPU design takes that to a new level.

There’s a lot to talk about when it comes to the new iPhone. Whether it is understanding the architecture of the A6 SoC or investigating the improved low light performance of the iPhone 5’s rear facing camera, we’ve got it here in what is easily our most in-depth iPhone review to date. Let’s get started.

Design

Section by Vivek Gowri
The iPhone 4, when it launched, represented a clean break for Apple's industrial design. It replaced the soft organic curvature of the iPhone 3G/3GS with a detailed sandwich of metal and glass, something that arguably brought the feel of a premium device to a new level. Obviously, Apple had their fair share of issues with the design initially, and nothing could match the sinking feeling of dropping one and shattering the glass on the front and back simultaneously, but it was a small price to pay for the jewel-like feel of the device. Combined with the (at the time) incredible pixel density of the then-new Retina Display, the iPhone 4 was a revolution in hardware design. The chassis has aged remarkably well over the last two-plus years, so naturally it's a hard act to follow.

The 5 keeps a similar design language to the 4, keeping roughly the same shape as before but with a taller and thinner form factor. At first glance, the 5 actually looks almost the same as the 4, with an unbroken glass front face, prominent corner radiuses, the familiar home button, a rectangular cross-section, and metallic sides with plastic antenna bands. However, those metallic sides are part of an anodized aluminum frame that makes up a majority of the body, and that's where the industrial design diverges from the 4 and 4S.
In contrast to the predominantly glass body of the previous generation iPhone, the 5 is almost entirely aluminum other than the glass front face and two small glass windows at the top and bottom of the back. It's a return to the original iPhone/3G/3GS-style of construction, with the front glass clipping into a unibody chassis. It's a significant departure from the 4 and 4S, where the stainless steel band in the center was the main housing that the front and rear panels clipped into. That was pretty radical way of doing things, so it's not all that surprising to see Apple revert to a more conventional and less complex method for the 5.

The aesthetic is actually pretty awesome, especially in the black version. The combination of black glass and off-black aluminum (Apple is calling it slate) gives the 5 an almost murdered out look that's three parts elegant and one part evil. The white and silver model has a classy look that's much friendlier in appearance than the black one. The color schemes and overall design aesthetic remind me of the Dell Adamo, one of my favorite notebook designs of all time. The similarities may be purely coincidental, but it's interesting to note nonetheless and should give you an idea of how premium the industrial design is.

All three previous iPhone body styles had very similar dimensions, so the biggest question with the 5 was how much the larger display would do to change that. Unlike many Android manufacturers, Apple still believes in things like small pockets, small hands, and one-handed smartphone usage. With the 5 being vertically stretched but no wider than the previous iPhones, the biggest impact on in-hand feel is actually the thinner body. If you're used to a larger Android or Windows device, the change seems radical, but even compared to the 22% thicker iPhone 4S, it feels a good deal smaller.
It's not just the minimized z-height though, the 25% weight loss is definitely also a factor. Even a few weeks later, I still find it striking how much less substantial it feels than the 4 and 4S. The densely-packed glass body just had a reassuring weight to it that the 5 simply lacks. But as you get used to the new form factor, you realize how far Apple is pushing the boundaries of ultrathin design. When the 4th generation iPod touch came out, I told Brian that I wanted an iPhone with that form factor - well, the 5 is essentially there (0.3mm thicker and 11 grams heavier, but close enough). It's pretty impressive to think about. If you thought the 4S was one of the best phone designs on the market in terms of aesthetics and build quality, the iPhone 5 just pushes that advantage further.

Add Yahoo Messenger online status to your web or blog

2012-06-22T01:26:00.000-07:00

Actually has a lot of tutorials that discuss about add YM (Yahoo Messenger) online status on your web/blog, but still many are not successful, which may be due to lack detailed descriptions or perhaps difficult to understand.
For those who want to display YM online status on your website or blog, or even on a forum posting that is usually useful if you sell online through a forum, can use the following ways which may be easily understood.
Copy and paste the following script code on a web page/blog/forum post that you want to show your YM status.

<a href=”ymsgr:sendIM?YM_id”><img border=0 src=http://opi.yahoo.com/online?u=YM_id&m=g&t=1 /></a>

Use the following script if you use WordPress blog (can use in your widgets).

<a href=”http://edit.yahoo.com/config/send_webmesg?.target=YM_id&.src=pg”><img border=”0?src=”http://opi.yahoo.com/online?u=YM_id&m=g&t=1&l=us”></a>

Next step:
- Replace “YM_id” with your YM account. For example: if your YM account are “qblog@yahoo.com”, then you only need to type “qblog” without “@yahoo.com”.
- Replace the “t=1″ in accordance with the picture that you like from the options shown below.

Creating a Subdomain On Localhost

2012-06-22T01:22:00.000-07:00

Create subdomains through cPanel or DirectAdmin is quite easy, but what if you want to create subdomains on localhost or local computer?
Here’s a guide to make a subdomain on localhost using WAMP.

1. Open the file called ‘hosts’ in the directory C:\Windows\System32\drivers\etc\ using any text editor. Add a new line with subdomain you want to ceate (for example: subdomain.localhost), so that it becomes like the example below.

127.0.0.1 localhost

127.0.0.1 subdomain.localhost

Then save and close the file.

2. Open the ‘httpd.conf’ file from the Wamp tray icon menu or in the directory C:\wamp\bin\apache\Apache2.2\conf\, and find the following line.

#Include conf/extra/httpd-vhosts.conf

And un-comment it by removing the ‘#‘ from the start of the line.

3. Open the ‘httpd-vhosts.conf’ file in the directory C:\wamp\bin\apache\apache2.2\conf\extra\, you should find 2 virtual hosts in there (dummy-host.localhost and dummy-host2.localhost). Delete both (the entire block), then replace with the following line.

<VirtualHost *:80>
ServerAdmin admin@localhost
DocumentRoot “c:/wamp/www/”
ServerName localhost
ErrorLog “logs/localhost_error.log”
CustomLog “logs/localhost_access.log” common
</VirtualHost>
<VirtualHost *:80>
ServerAdmin admin@subdomain.localhost
DocumentRoot “c:/wamp/www/subdomain”
ServerName subdomain.localhost
ErrorLog “logs/subdomain_error.log”
CustomLog “logs/subdomain_access.log” common
</VirtualHost>

And finally, restart Apache from the Wamp tray icon menu.
If you run into problems after the restart, check the Apache error log. You may also need to restart your PC for Windows to pickup the changes you made to the Hosts file.

SMS (Short Message Service) is a very popular service which used to send a short message to someone via cell phone. To send a message would require a gateway to the dissemination of information by using SMS.

Are you interested to create your own sms gateway, so you can provide a free sms service on your sites?

Nowadays, many websites that provide a free sms service, even now you can also create your own free sms service on your website in a way that is not too difficult.

How to build your own sms gateway?

1. First you need Gammu software and MySQL. Gammu is an application to build a sms gateway which connects between the mobile operator with the internet. Even Gammu can also be used to make a voice call and is available for Windows and Linux platforms. While MySQL is used as database server.

You can download Gammu application here.

2. Then install Gammu in the root directory or in the C drive on Windows platform.

3. Perform Gammu configuration by editing the “GAMMURC” file located in the Gammu installation directory. You’ll find the two parameters that you have to fill the ‘Port’ and ‘Connection’.

‘Port’ parameter must match with the the cell phone port number which attached to computer. Make sure that your cell phone driver already installed properly on the computer. To find the cell phone port number can be seen on the “Phone and Modem Options” in the Contorl Panel.

example:

Port = com3:

Connection = at115200

4. Next, do test the connection by going into the Gammu installation directory via DOS Command Prompt, then type “gammu identify” command like the example below.

example: C:\gammu>gammu identify

If you see information about your cell phone connection, such as Model, Revision, Manufacture, and IMEI, then the configuration has been successfully done, but if it does not show information about your cell phone connection, then it is likely configuration is not correct, check the parameters of the ‘Port’ and ‘Connection ‘in step no. 3.

5. The next step is to create the MySQL database are Gammu required as SMS Gateway. You can also use other server database application that you are more familiar know other than MySQL.

Create a database using phpMyAdmin, as for example with the name ‘sms’. Then create new tables are needed for Gammu. You can see the Gammu required database tables in the ‘mysql-table.sql’ file located on the Gammu installation directory.

6. Perform configuration daemon on Gammu SMS for automated reading process SMS messages sent or received and then stored in a database.

Open the file ‘SMSDRC’ located on Gammu installation directory, then edit using a text editor such as Notepad. The following parameters must be configured:

port = port number
connection = connection type
service = mysql (if using MySQL)
user = username account on the server
password = password defined for the username account on the server
pc = IP address or host name of the server (default: localhost)
database = sms (adjust with the database name that you created)

7. If you want to run Gammu as a Windows service, you can use the command “gammu-smsd -c smsdrc -i” (without quotes) via DOS Command Prompt. If successful, you will see Gammu applications on Windows Services list.

8. The final step is to connect the SMS Gateway with your website. To perform this step you will need the public IP (the IP you get from the ISP you use) or IP hosting your web server and a PHP script to perform the process of sending a message.

scripts example:

Copy the script below and paste it into Notepad or other text editor and save with the name “form_sms.php” (without quotation marks).

<form name=’formSMS’ action=’send_sms.php’ method=’post’>
<table width=’250px’>
<tr>
<td><a style=’text-decoration:none;’ href=”http://your_domain/form_sms.php” alt=”Free SMS” target=”_blank”><b>Free SMS by Qblog</b></a></td>

</tr>

</table>
</td>
</tr>
<tr>
<td><input class=’btn-submit’ type=’submit’ name=’btnSubmit’ value=’Send’/></td>
</tr>
</table>
</form>

“send_sms.php” script.

<?php

mysql_connect("dbhost", "dbuser", "dbpass");

mysql_select_db("sms");

$phone = $_POST['noTelp'];

$message = $_POST['shortMessages'];

$query = "INSERT INTO outbox (DestinationNumber, TextDecoded, CreatorID) VALUES ('$phone', '$message', 'Gammu')";

$result = mysql_query($query);

if ($result)

echo "SMS sent";

else

echo "SMS failed";

?>

Upload both files on your web server, and specify its location. If you put it on the root, it can be accessed at the URL http://your_domain/form_sms.php

You can see examples of websites that provide free sms service on http://bloqita.net . Bloqita is a blog media network which has many features and facilities of social networking as a media gathering place for bloggers, and one of those features is a free sms service.

How To Unlock ZTE Modem

2011-12-03T09:19:00.000-08:00

Many broadband users usually buy ZTE modems with internet data packages from various network operators such as T-mobile, Three, Orange and Verizon for connecting to the internet. However, most of the mobile network companies lock their modems to avoid using with another network companies. Therefore, most of the people need to unlock their modems for using with other networks. In this article, I will discuss about unlocking ZTE HSDPA modems. Here, I used dccrap in this unlocking process so that before you connect the modem to the USB, you need to put an invalid operator SIM Card. Hence, the software can identify your modem for unlocking. Let's see how to do this process step by step. You can get unlocking software from the below links.

First of all, put an invalid SIM card to the modem and remove memory card if it already contains a memory card. Then, connect the modem to the USB port on you PC. Close the ZTE software if it automatically opens when the modem connect to the PC. Now, extract the downloaded folder and run the dccrap.exe

Choose ZTE datacards in a select manufacture option and then press the search button below. Hence, it will detect the modem and display the details of the modem.

Now, you can click Unlock button for unlocking the modem. While i was taking these screen shots, i don't have a modem for unlocking. So, you will see that the unlock button is disabled in the below screen shot. But, in actual case, unlock button will be enabled for unlocking.

Your modem will be unlocked instantly........

2011-12-03T08:52:00.000-08:00

Huawei internet modems are the most popular modems in the market. When you buy a modem from the market, it is probably locked to a single mobile operator such as T-mobile, 3, Orange, Vodafone or Verizon. Therefore, you can use that modem only with one operator. Sometimes, Locking to one operator is annoying for most of the modem users. So, You must unlock your Huawei modem to use with any SIM. Today, I'm going to discuss on unlocking a Huawei modem within several minutes. Using this method, unlock code can be easily calculated by entering the IMEI number of the modem.

Download the huawei unlock pack from the download links and run the Huawei Unlocker.exe. Enter the IMEI number of the modem to the application and click on Calculate button. It will generate both Unlock Code and Flash Code. Insert the modem into the USB port without having a SIM card.

Copy the Unlock Code and then run the HUAWEI MODEM Code Writer.exe. Now, Click on the "Please Selecet Com Port " button.
After, Click on the Detect button then it will detect your 3G modem, select the 3G modem and click Accept button.
Press the Unlock Modem button, it will open a small window

Press the Unlock Modem button, it will open a small windowas shown in figure below.

Paste the Unlock Code that we copied earlier and click OK button to unlock the modem. Then, it will successfully unlock your modem.

Now, you can use that modem with any SIM card without any trouble.

How to enable Task Manager,Folder Options and Registry editor in windows

2011-12-03T02:49:00.000-08:00

In Some computers, when the user clicks Alt+ctrl+del, it does not popup the task manager. It happens mostly after attacking a malware. Also when user access into the registry editor by typing start > run > then type "regedit" without having quotes, it says Regitry Editor has been Disable by Administrator. This is also due to a malware attack. Therefore, in such a situation you can use this tricks for solving them. Sometimes your computer may not display Hidden Files and Folders due to same problem.

In windows xp , open windows explorer by clicking on My Computer

select tools > Folder options > view

then you can tick the "show hidden files,folder ...."

In windows 7 & vista

open windows explorer by clicking on My Computer

click organise " select folder and search options"

then you can tick the "show hidden files,folder ...."

But you can not simply do this when the malware is attacked to the PC.

you can use this RegistryFix.exe application for enabling Registry editor

http://www.mediafire.com/?0q6i5wg7h9rb9v7

download the application using above link and simply double click on it to run

you can use this TaskManagerFix.exe application for Enabling Task manager

http://www.mediafire.com/?vz8t3vyy3le7z9c

download the appplication and simply double click it

If your PC does not display Hidden Folders(in folder options) , you can run this application to solve that problem

Then click on Repair Button

http://www.mediafire.com/?xpz5qoah43eb322

Also there are some other methods for doing that...

There is a registry hack to enable or disable Windows NT TaskManager. The same registry hack applies to Windows 2000 and Windows XP.

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\Policies\System
Name: DisableTaskMgr
Type: REG_DWORD
Value: 1=Enablethis key, that is DISABLE TaskManager
Value: 0=Disablethis key, that is Don't Disable, Enable TaskManager

As part of the enhanced management available in Windows 2000 and Windows XP, rather than risking a registry change, as an administrator you can enable or disable Windows 2000 Pro or Windows XP Pro's TaskManager using Group Policy Editor. This can be applied to the local policy. Note: if you are trying to override your organizations group policy, you can't. As soon as you re-authenticate to the domain, the domain or OU Group Policy will rewrite the registry setting. But if the TaskManager was accidently disabled or you need to control this item for a set of standalone boxes this is for you.

How To Disable USB Ports To Prevent Malware Infection

2011-12-03T02:39:00.000-08:00

Many people use USB flash drives for transfer files, they often plug their Flash drives for many computers. Therefore, most of the usb drives are contained malwares, viruses etc. On the other hand, these USB drives are the spreaders of that kind of malicious applications. If you can disable or lock USB port temporarily, they can not be able to plug their Flash drives to your Computer or Laptop. There are several ways for disabling USB ports such as using Regstry Editor, Disabling autorun and using software. Today i am going to discuss about how to disable and enable the USB ports.

First, you need to go to Registry Editor (Start > Run > type " regedit " without having quotes).

* in the Registry Editor, Go to HKEY_LOCAL_MACHINE >SYSTEM>CurrentControlSet >services>USBSTOR
Double click on the start key which is in the right side. Then it will open a window, you will see Value Name and Value data. In the value data field , you can change the value to 4 to disable USB ports. When you change that value to 3 it will enable USB Ports.

You can also write a Registry Key for doing this process, simply open the Notepad and write below code exactly as it is. Then, save it by giving a name with .reg extension and set ANSI as Encoding.
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor]
"start"=dword:00000004

Change the Save as type to "All Files" and give a name with .reg (ex: Disable_usb.reg) as shown in below figure.

Now,you can also make reg file for enabling USB Port by changing dword value to 00000003.
By double clicking these two reg files, it can be easily Disable and Enable USB Ports. Remove the USB Drive and again plug for applying these settings. I have made these Registry Files for you so, if you unable to make these files download it from here Download.

There is a small application available for Disabling and Enabling USB Ports called USB Port Locked 2.0. Using this application, it may be easily done.

Convert Images To .txt

2011-12-03T02:35:00.000-08:00

Recently, i found small application called Image2Txt that can convert images into text format using PHP code. Also, it is very easy to use even for a person who do not have good knowledge about computers. Resolution and character number settings determine the length of the characters in rows and columns. in resolution, the lowest value 2 provides the maximum possible resolution for the selected image.

When you increase the value which greater then 2, the character’s size and resolution may reduced. Hence, at the beginning you need to do is simply install the application and click on the open image to load the image. Select any image and Change the Resolution value. After selecting a image it will display in the application. Then, click on the Convert button. When you click on the Convert button, it will convert the image into text so you can copy that the generated text into a text editor like Notepad.

Original image that i got for convert to text

Convert RAM Into Graphic Card

2011-12-03T02:27:00.000-08:00

This tutorial should help you get started with using the basic features in 3D Analyze. Most games will use roughly the same settings in order for it to run, but some games will require specialized settings. This tutorial will not cover that, but if you come across a game such as this you can search the forums for help or experiment with settings yourself to try and get the game to run.

So, how to use 3D Analyze:

1. Download 3D Analyze 2.36, you can get it from the 'Downloads' page.
2. Extract 3D Analyze to a folder, and run 3D Analyze.exe.
3. Once it has opened click on 'SELECT', and browse for the .exe file for the game you want to run.
4. You will usually want to tick all of the options under 'Hardware Limits'. Some games only need 'emulate HW TnL caps', so
you might need to experiment around.
5. Try running the game by clicking on 'RUN'. If it doesn't work, then there are a million things to try. I'll only list a few.
6. Some games will also need you to check 'force SW TnL' under 'Performance'. Not all games need it though, since 'force SW
TnL' roughly equates to 'emulate HW TnL'.
7. Specific games have built-in solutions, so if you're playing one of the games listed under 'Game/Demo Fixes', check the game
you're playing.
8. Some games will only recognize certain 3D card brands and models. If so, enter the values of the given cards in the 'VendorID'
and 'DeviceID' section. Only 4 types/models can be emulated though, so experiment around with the 4 values given.
9. If it still doesn't work, then check and search the forums. Someone might have discovered the settings you need.
10. If, and only if there are no previously discovered settings, post a new message asking for help.

You can download 3DAnalyzer from here Download
you can Virtually emulate NVIDIA GeForce TI 4600,NVIDIA GeForce FX 4900 ULTRA,ATi Radeon 8500, ATi Radeon 9800 PRO

2011-10-27T09:04:00.000-07:00

If you are Blackberry users and looking for some cool applications for your Blackberry phone. Then you come to the right place. Because i am going to share the 10 application you should have on your Blackberry phone.

1. Facebook
The application lets you update your own status and view your friends’ posts, as well as upload and tag photos right from your phone. We also like the improved photo viewing experience from within the app. Facebook even leverages BlackBerry push technology, so you get messages and updates in real time. Our favorite feature is the calendar integration; the application reminds you of every Facebook event and of your friends’ birthdays.
Price:$ Free

2. Gmail Client
Gmail client is the next most useful and must-have Google app for your BlackBerry. This app gives you almost the same functionality as the Web-based Gmail by giving you access to your contact list, sent and archived mail as well as the labels functionality.
Price:$ Free

3. Google Latitude
Latitude allows a mobile phone user to allow certain other people on his or her Gmail contact list to track where he or she is. These people can track the user (or more accurately, his or her phone) on Google Maps via their own iGoogle accounts. The user can control the accuracy and details of what each of the other users can see — an exact location can be allowed, or it can be limited to identifying the city only.
Price:$ Free

4. Google Mobile
Helps you to get the whole Google experience right on your BlackBerry mobile. It has Gmail, Google Maps and Google Sync plus links to Google’s mobile-optimized Web services such as Web search, Google Reader, Google Docs and Picasa.
Price:$ Free

5. Google Talk
You also need to communicate with your non-BlackBerry using friends. This app sports an interface similar to the BlackBerry Messenger and is as robust as other paid IM client for the BlackBerry.
Price:$ Free

6. BBNotePad
BBNotePad is a free text file editor/creator application for BlackBerry. It simply lets you save, edit, & create text files on your BlackBerry SD card or memory. The developer also added some more functionality in this release.
Price:$ Free

7. TwitterBerry
Twitter addicts know that a key purpose of the service is to stay in touch with your friends and colleagues on the go. While you can do that with SMS messages or Twitter’s WAP page, TwitterBerry is a far better way. The app aggregates status updates and offers simple, one-click delivery of your all-important 140-character missives—perfect for that inspired existential insight that pops into your head while you’re waiting in line at the bank.
Price:$ Free

8. Pandora for BlackBerry
Pandora Radio is your own FREE personalized radio now available to stream music on your BlackBerry. Just start with the name of one of your favorite artists, songs or classical composers and Pandora will create a “station” that plays their music and more music like it.
Price:$ Free

9. ShoZu
ShoZu makes sending your BlackBerry pictures to your favorite social networking sites—including Facebook, Flickr, Twitter, WordPress, and YouTube—easy. Once you’ve installed the application and chosen your destinations, each time you take a picture or record video, you’ll be able to upload that media to them. We like that on a Symbian S60 ShoZu automatically asks to upload a new photo to your site of choice; on a BlackBerry, however, you have select which social networking sites to use for each upload. You can also use ShoZu for BlackBerry to add descriptions and titles to your photos before uploading them, but we weren’t able to read comments on the photos or geotag them from our BlackBerry—two features we were able to use on the S60 version and we hope will be added before ShoZu leaves beta.
Price:$ Free

10. Mobipocket Reader
Given the fact that BlackBerry devices are not the best for eBook reading, this app fully utilizes the devices display to bring you a decent reading experience. And since it supports the .mobi format, you are assured that you’ll have plenty of eBook titles to chose from and download on your BlackBerry devices. You can also convert PDFs or Word files on your PC and transfer them to your BlackBerry device.

Speed Up Your Server Performance With Nginx

2011-10-27T09:02:00.000-07:00

Apache is one of the best well known web server, that run in all platform, but usually on Linux in production mode. Apache supports a variety of features, many implemented as compiled modules which extend the core functionality. Both static files (css, js, html, image files) and dynamic files (php, pl, py, etc.) are served equally using same amount of resources. Which will cause bottleneck in system performance when your website have lot of static files and lot of traffic.

To prevent this, we can use nginx (read: engine x) to serve static files and use apache to serve dynamic files. To do this you can configure both nginx and apache web server to work together. Where nginx installed as reverse proxy. So nginx will filter all the requests, where static files will serve by nginx and dynamic files will pass to apache.

This technique will certainly improve your server performance, since nginx is incredibly fast in serving static files and apache will use resources efficiently (because only serve dynamic files/server script). And the next step is load balance the nginx with other nginx. So it is possible for you to make your own cdn (content delivery network). So you just need to buy another small server just in another location to serve your visitors from nearest location to your server.

What Is Squid Proxy Server

Squid is a Unix-based proxy server that caches Internet content closer to a requestor than its original point of origin. Squid supports caching of many different kinds of Web objects, including those accessed through HTTP and FTP. Caching frequently requested Web pages, media files and other content accelerates response time and reduces bandwidth congestion.
A Squid proxy server is generally installed on a separate server than the Web server with the original files. Squid works by tracking object use over the network. Squid will initially act as an intermediary, simply passing the client's request on to the server and saving a copy of the requested object. If the same client or multiple clients request the same object before it expires from Squid's cache, Squid can then immediately serve it, accelerating the download and saving bandwidth.

Internet Service Providers (ISPs) have used Squid proxy servers since the early 1990s to provide faster download speeds and reduce latency, especially for delivering rich media and streaming video. Website operators frequently will put a Squid proxy server as a content accelerator, caching frequently viewed content and easing loads on Web servers. Content delivery networks and media companies employ Squid proxy servers and deploy them throughout their networks to improve the experience of viewers requesting programming, particularly for load balancing and handling traffic spikes for popular content.
Squid is provided as free, open source software and can be used under the GNU General Public License (GPL) of the Free Software Foundation. Squid was originally designed to run on Unix-based systems but can also be run on Windows machines.
Squid was originally an outgrowth from the Harvest Project, an ARPA-funded open source information gathering and storage tool. "Squid" was the code name used to differentiate the project when development in the new direction was initially begun.
