Enabling AHCI after Windows 7 installed on IDE Mode

2012-02-06T13:54:00.001-08:00

If there is any chance that you guys installing windows 7 while in IDE mode for your SATA drives (just like me) and now want to change it to AHCI mode in the bios only to get windows startup crash, here is the step.

in the BIOS, change back the SATA mode to IDE, start windows normally and do below step :

1. start "Regedit"
2. Go to : HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services
3. Open msahci
4. In the right field double click on "start".
5. In the value Data field enter "0" and click "ok"
6. exit "Regedit"

restart your PC, back to BIOS again, and change the SATA mode to AHCI, your windows should start without any problem.

TP-Link TL-MR3420 Wireless router is compatible with Nokia E52 Phone

2011-06-20T06:10:00.000-07:00

I just realized today that my TP-Link Wireless router is supporting Nokia E52 phone on its native firmware, without any additional modem firmware.

although on their website, nokia support isnt mentioned anywhere, it does detect the nokia phone as 3G USB modem, here is the "officially" modem support from their website.

and here is my TL-MR3420 configuration that shows Nokia E52-1 as 3G USB Modem.

if somebody mind to ask, why I use my expensive phone as 3G modem on wireless router ???, why not ??, I have unlimited data plan on the phone, and the router is charging the phone too on its USB port. :-D

==========================

update for firmware version :

Firmware Version: 3.11.10 Build 100901 Rel.52652n
Hardware Version: MR3420 v1 00000000

Got error code 2869 on Vista or Seven ??

2011-06-02T06:28:00.000-07:00

Basically this error is coming from MSI packages that build for system before Vista, means, installation process is not compatible with new security schemes that applied on Vista and 7.

on EXE file type installation, we can right click on the icon and choose "Run As Administrator", but on MSI packages, we dont have that option, here is the work around to get MSI packages run under administrator privileges.

1) Copy the .MSI file to the root directory of main hard drive (i.e. C:\).

2) Open Windows Notepad.

3) Copy this text into windows notepad:

msiexec /i C:\program_name.msi

4) Replace the text "program_name" in with the actual name of the .MSI file .

5) Click File -> Save ...

Instead of saving it as a .txt file, change the file name to installer.bat.

Save the file to place where we can find it easily, ie desktop.

6) right click on the file and select Run as Administrator.

Make Fedora Linux as Xserve file server for Mac

2011-05-24T18:41:00.000-07:00

Apple need afp to connect to other server, and that means linux need to run one.

first install netatalk and avahi.


#yum install avahi netatalk

for RPM package, on my case, I use Fedora 9, so here is the RPM that my linux has :

avahi-0.6.22-10.fc9.i386, netatalk-2.0.3-21.fc9.i386

Configure Appletalk Netatalk


# vi /etc/atalk/afpd.conf
- -noddp -tcp -uamlist uams_randnum.so,uams_dhx.so,uams_dhx2.so -nosavepassword -advertise_ssh

# vi /etc/atalk/netatalk.conf

Change the following values:


ATALKD_RUN=no
PAPD_RUN=no
CNID_METAD_RUN=yes
AFPD_RUN=yes
TIMELORD_RUN=no
A2BOOT_RUN=no

Configure Netatalk to share home folders


# vi /etc/atalk/AppleVolumes.default

allow: users and groups allowed to access share

rwlist: users and groups allowed read and write access

Change <users> to your users separated by commas jim.bob.doug
Change <@group> to your groups separated by commas @accounting, @marketing (keep the @ infront of the group name)
* Users and Groups must already exist in Linux

Add for Users Home Folders


~/ "$u" allow:<users> rwlist:<user>,<@group> cnidscheme:cdb

Add a folder:


/home/folder <share_name> allow:<users>,<@group> rwlist:<users>,<@group> cnidscheme:cdb options:usedots,upriv

Configure Avahi and mDNS (linux version of bonjour)

We need to configure Avahi and mDNS so the Mac computers on the network can find our Appletalk file server

We need to create a service file for our afpd service:


# vi /etc/avahi/services/afpd.service

Add the following:


<?xml version="1.0" standalone='no'?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<name replace-wildcards="yes">%h Xserve</name>
<service>
<type>_afpovertcp._tcp</type>
<port>548</port>
</service>
<service>
<type>_device-info._tcp</type>
<port>0</port>
<txt-record>model=Xserve</txt-record>
</service>
</service-group>

Add mDNS to nsswitch


# vi /etc/nsswitch.conf

Add mdns to the line hosts:


hosts:      files dns mdns

add static route after vpn interface up on Mac OSX

2011-02-04T18:13:00.000-08:00

to do this on mac is simply create a script and put it under /etc/ppp/ , and name it ip-up, here is my example, on script you can see I need both 10.10.20.0/24 and 10.10.10.0/24 to be routed to ppp interface after vpn interface get connected.



bash-3.2# 

bash-3.2# cat /etc/ppp/ip-up 

#!/bin/sh 

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/System/Library/CoreServices; export PATH

 

ifppp=$(ifconfig ppp0 | grep inet | awk '(print $2}') 

/sbin/route add -net 10.10.20.0/24 $ifppp 

/sbin/route add -net 10.10.10.0/24 $ifppp 



bash-3.2#

DG31PR Geekbench result on Mac OSX vs Windows7

2011-01-08T00:33:00.000-08:00

This is the reason I keep my DG31PR mobo to run hackintosh, instead of installing it with Msoft OS, named Windows 7.

Geekbench 32bit result show different performance between OSX 10.5.8 and Windows 7, and honestly, I can feel this system run better on OSX compare to Windows 7.

another reason why I use this OSX, its solve the audio problem on DG31PR, this motherboard known to has bug on its onboard audio chip, some people solve it by adding a soundcard, but I found installing OSX make the problem goes away.

while using Windows 7 (and XP too), I got no sound on audio output in random situation, almost everytime I start my computer, I got no sound, restarting the PC sometimes solve the problem, but mostly not, but when running OSX, only sometimes I got no sound, and on this situation restarting the PC always solve the problem.

Well, now I am a Mac User :D.

There was an error while gathering this information fix

2010-11-28T03:01:00.000-08:00

Really annoying to get "There was an error while gathering this information" on System profiler, after hours looking through internet, several try and noresult, finally get it fixed, here is the step.

remove :

/System/Library/SystemProfiler/ SPPlatformReporter.spreporter
/System/Library/SystemProfiler/ SPiPlatformReporter.spreporter

get from any MacOSX DVD installation using pacifist the original for those file above, copy them from DVD to above directory, remove /System/Library/Extensions.mkext and reboot. it should get it fixed.

I got this instructions from this link, but instead using 10.4.10 DVD (as it said on that page instructions), I am using any DVD that available on my shack, and found iatkos 10.5.4, currently I am running 10.5.8 system, installed through ideneb 1.5.1.

side note : you need to have this SMBIOSEnabler.kext installed on your system too, and edit the contents of /System/Library/Extensions/SMBIOSEnabler.kext/Contents/Info.plist to reflect your system info.

Nvidia XFX GF 9400GT 550M 512MB on 10.5.8 osx

2010-11-27T05:54:00.000-08:00

I can confirm that XFX GF 9400GT PCI-E card (Product Code: PV-T94G-YAK2) can run on OSX 10.5.8 (with ideneb 10.5.1) installation (then do the combo upgrade from mac website) with full QE/CI support.

things you need are :

nVidia Driver from this link or this link.
osX86Tools
edit com.apple.Boot.plist under /Library/Preferences/SystemConfiguration/

here is procedure to edit that com.apple.Boot.plist

1. Open osX86Tools.
2. Click on Add EFI Strings/Boot Flag and open it
3. now do these steps:
4. Click GFX String [On upper Left]
5. On Graphics Card, Drop down the list and choose Custom Geforce [should be at very last]
6. On the box Type 'nVidia Geforce 9400 GT'
7. Select 512MB as cards Memory and click OK
8. Select VGA / DVI-I as display output configuration (NVCAP) note : this one need to be correct, I tried the DVI-I / VGA before, and it didnt work.
9. Copy Hexadecimal EFI String box contents and paste it to previous OSx86Tools windows called Boot Editor on the box above "Apply Changes to com.apple.Boot.Plist button.
10. close all and then restart the machine, your screen will now ready and good to go like mine, as you see on the snapshot above, its feed 24 inch screen with 1920x1200 resolution, nice...

other link to read, the same nvidia 9400 chipset video card but different brand.

What is the Windows 7 edition that is best for me ?

2010-11-16T21:39:00.000-08:00

Linux USB Drive boot problem

2010-08-21T17:35:00.000-07:00

Universal-USB-Installer.exe from http://www.pendrivelinux.com is great tool to make any linux boot on USB flash drive, but one weird thing happened to me, I bought couple 4Gb USB flash, none of them work and giving this Syslinux load error :

No Default or UI Configuration Directive found!...

but when I use my smaller flash drive (ie 1Gb and 512Mb) it work just fine.

figured out for a while, typed this on the prompt below that error message :

grub# vmlinuz initrd=initrd.gz pmedia=cd

with that line typed after the error, my usb boot work just fine, then I checked what files are inside my flash drive, I found there is no syslinux.cfg, only isolinux.cfg, so I renamed the file to syslinux.cfg, and bam, every time I rebooted the machine, it work without any intervention.

I know since long time ago, isolinux.cfg is for CD boot, and for HDD boot, it use syslinux.cfg, but not sure why my 1Gb and 512Mb flash drive able to boot its linux kernel with isolinux.cfg.

anyway, just change isolinux.cfg to syslinux.cfg, and it will take care the problem.

openvpn simple command

2010-07-03T23:53:00.000-07:00

here is two simple command to have openvpn tunnel up between server and client on linux system

on server :

/usr/local/sbin/openvpn --port PORT --proto udp --dev tun0 --bcast-buffers 512 --fast-io --ifconfig 192.168.20.1 192.168.20.2 --comp-lzo --comp-noadapt --daemon --route some_net its_masking 192.168.20.2 --keepalive 30 90

on client :

/usr/local/sbin/openvpn --remote SERVERADDR --port PORT --proto udp --dev tun0 --bcast-buffers 512 --fast-io --comp-lzo --comp-noadapt --daemon --ifconfig 192.168.20.2 192.168.20.1 --keepalive 30 90 --float

Audiocodes Hunt Group routing table and its Routing Manipulation

2010-06-07T14:24:00.000-07:00

After configuring audiocodes to work with asterisk, one thing need to be done properly, to make audiocodes just route the ip call to PSTN the way asterisk want it.

on my case here, I have my asterisk adding prefix 011 and 012 before sending it to any FXO gateway attached to my asterisk, the problem is audiocodes by default will use hunting system and use any available FXO to make a call, which I dont want it to be happen as every port is attached to different provider and I want the call to be routed properly to save the cost (and cost calculation is done on asterisk).

two configurations need to be done on audiocodes for this case :
1. Protocol Management -> Manipulation Tables -> IP Tel Destination Numbers, below is the screen shot.

2. Protocol Management -> Routing Tables -> IP to Hunt Group routing, below is the screen shot.

by looking at both screen shot above, we will get the idea easily.

Intel T7300 on Sony Vaio VGN-NR220E

2010-06-01T12:49:00.000-07:00

This is another upgrade for my 2 years old Sony Vaio VGN-NR220E. As previous project done to this low cost laptop (I got it for only US$ 320, on BestBuy sale) that changed it from Windows Vista to Windows XP and then to MacOSX Leopard 10.5.2, everything was fine except the horse power that come with this laptop, Intel T2330, is not really a horse power, more like mule power :D.

Last week, I look for the replacement of its processor, I was looking for T8100 processor initially, as other guy do the upgrade on this laptop with success ( this link ), but after looking around at ebay, this processor is still damn expensive, even used one, the price never below US$80.

Well, then I had to lower my expectations, I only need faster processor, bigger cache, and most important thing, can do virtualization, so T7300 is my next choice, if this laptop can do T8100, so it should be able to do T7300.

finally after 2 weeks restless bidding on ebay, got a bargain price at US$48, it used one but come with 30 days warranty, not bad at all.

now I am a happy user, my MacOSX Sony Vaio is run faster then before, I completely migrated my XP to run under MacOSX with Virtual machine that utilize its intel VT-x hardware virtualization, sweet.......

below pictures are for comparison of the core size between T2330, T8100 and T7300.

Disable copy and paste into form text field

2010-05-31T16:19:00.000-07:00

People sometimes got lazy just to enter information such thing like this below :

your email :
confirm your email :

the second question to confirm your email address, or to be exact, to retype again the email address is having a purpose to minimize the typo or any other problem like incorrect email address, or by mistake, entering another person email address.

but because of laziness, many times for second question, people just do copy and paste, ctrl-c and ctrl-v to that column, so at this point, the purpose of having second question is no longer valid anymore.

to prevent such behaviour, here is simple trick on the HTML form.

<input type="text" class="medium" name="contactEmail2" id="contactEmail2" onCopy="return false" onDrag="return false" onDrop="return false" onPaste="return false" tabindex="23"/>

with that addition, people are no longer able to do paste/ctrl-v into it.

I always need this once a while and always forgot it, so this is my note on ipv6 for linux (Fedora flavor of course :) ).


/sbin/vconfig add eth0 600
/sbin/ifconfig eth0.600 up
/sbin/ifconfig eth0.600 inet6 add 2001:AA00:F:F::2/64
/sbin/route -A inet6 add ::/0 gw  2001:AA00:f:f::1

Patch Asterisk 1.4 to work with MagicJack.

2010-03-07T16:26:00.000-08:00

I know, its against MagicJack TOS but I have to do this because that small MJack USB phone adapter is hot, I really dont like to have it that way while attached in my laptop.

once MagicJack guys can fix that issue, I will back again to use that phone adapter, here is the suggestion for you guys, put some power management control on that adapter, and just enabled the rest of device (that make it hot) only when there is a call placed, seems simple ha ? yes it is dude.

and why I bother to use MagicJack with Asterisk and not using any SIP Adapter directly ?, because I dont know how to configure SIP adapter to work with MagicJack server .. :D

here is the step (I use Asterisk 1.4.24, not sure if this work on 1.6).

1. go to asterisk source, on this directory ../asterisk-1.4.24/channels
2. download chan_sip patch
3. patch -l chan_sip.c < mjack_patch_chan_sip.patch
4. rm chan_sip.o chan_sip.so
5. cd ..
6. make
7. cp channels/chan_sip.so /usr/lib/asterisk/modules/chan_sip.so
8. start asterisk /usr/sbin/asterisk -Fvvvvvvvvvv
9. have fun.

Configuring Audiocodes MP108 MP104 FXO with Asterisk

2009-10-15T22:49:00.000-07:00

Audiocodes MP108 FXO is 8 FXO port on single device, its really well built, but with that, it comes with a lot of setting to deal, basically audiocodes is not simple FXO gateway which normally relies on asterisk to do the switching/PBX stuff, I hope that I can disable all the functionality and just use this gateway with asterisk.

ok now how to set this audiocodes just to forward all call come from PSTN that connect on FXO port to asterisk and vice versa, forward all call from astersik to any available FXO port, this is the few step that will make audiocodes work with such configuration.

Step 1:

Configure audiocodes to have registration account with asterisk, this can be done easily with "Protocol Management -> Protocol Definition -> Proxy&Registration", fill on "Proxy IP Address", "Enable Registration : Yes", "Username", "Password", and "Authentication Mode : Per Endpoint".

Step 2:

Configuring "Protocol Management -> Endpoint Phone Number", this is important part for make each FXO port on audiocodes registered with asterisk, in here, under "Channel", you can fill with either 1, 1-2, 1-8, 3-4, or whatever you want to have, this means that port 1, or port 1-2, etc will registered on astersik with userid/username filled on "Phone Number", yes, that is correct, "Phone Number" on this configuration page is AlphaNumeric, the password is using global "Password" on First step.

next, on same page configure "Hunt Group ID", this is another important configuration which make audiocodes forward incoming call from asterisk to any available FXO. Hunt Group ID is number from 0 to any, I put 1.

Step 3:

to make audiocodes forward call from FXO to asterisk, configure "Endpoint Settings -> Automatic Dialing", I have 777 number on asterisk to handle all incoming call, so I put "Destination Phone Number" as 777 so every incoming call on FXO will be forwarded to 777 on my Astersik.

Step 4:

this is the last configuration that everyone need, forward call from asterisk to any available FXO. in "Routing Tables -> IP to Hunt Group Routing Table" configure under "Dest. Phone Prefix" with "*" (or any prefix that you might have), "Source Phone Prefix" with "*", "Source IP Address" with "*", "Hunt Group ID" with any number you configure on Step 2, in my case, 1.

thats it, all configurations are complete. the audiocodes now can forward the call from FXO to asterisk, and vice versa.

step 3 and step 4 basically the configuration that need to have if audiocodes reporting error such "[ERROR] #0:TrunkGroup::AllocateEndPoint- Can't find EndPoint for phone number"

SELinux is preventing the mysqld from using potentially mislabeled files

2009-08-30T15:10:00.000-07:00

"setroubleshoot: SELinux is preventing the mysqld from using potentially mislabeled files, ...., For complete SELinux messages. run sealert -l ...."

above error is appear after I manually copy Mysql data files from /var/lib/mysql directory from one server to another new server, I usually choose this direct copy path to create another identical mysql server machine for its effectiveness, its faster compare to use the regular mysql tool.

but when the linux machine has SElinux enabled on it, direct copy will resulting the file unreadable from mysql server point of view, it will showing above error, to make these data file readable on mysql simply issue this command :

chcon --reference=/var/lib/mysql new_db_directory/*

Ubuntu gutsy got "package is missing, has been obsoleted etc"

2009-08-18T21:01:00.000-07:00

Its sucks maintaining an old server while upgrading the OS is not an option, especially if said machine is just work fine and serve well with its obsolete hardware and not worth enough to put some additional investment, except just add a hard drive.

while trying to update using apt-get, if one got the :
"package is missing, has been obsoleted, or is only available from another source" error, update the content of /etc/apt/sources.list with below entry, all obsolete ubuntu now filed under old-releases.ubuntu.com server :

running asterisk with SELinux enabled

2009-08-10T16:33:00.000-07:00

The common problem on asterisk running on top of linux with SELinux enabled is the error while trying to load the codecs

the error usually said :

loader.c:359 __load_resource: /usr/lib/asterisk/modules/codec_g729.so: cannot restore segment prot after reloc: Permission denied

The majority of user just disabling the SELinux, but if that is not an option, just change the context of said file above wiith this command :

chcon -t texrel_shlib_t /usr/lib/asterisk/modules/codec_g729.so

Unlock Linksys Sipura SPA 2102

2009-05-31T01:44:00.000-07:00

To unlock this linksys SPA 2102, just do exactly the step for unlocking Sipura SPA2100 on my other post.
I did it three times, all SPA-2102 no matter the model number, either SPA-2102-R, SPA-2102-NA or SPA-2102-SF, all can be unlocked using same step.

note: the only difference on my case with Linksys SPA, the file name on web server is spaMAC.cfg compare to Sipura SPA2100 that use spaMAC.txt as default.
