Just bought a new pc/laptop?

The best thing to do is create a clone image from your new pc/laptop before you start configuring or installing anything. Over the time, if you need to refresh your OS, it'll just take 10 minutes to restore from clone image and you'll have that new pc/laptop feel again.

Google on how to create clone image...or email to me personally if you want a tip!

Convert back from Ext3 to Ext2.

Forwarding Remote Desktop

I require forwarding of a remote desktop because a pc with windows XP is in different network segment than my laptop. In between, there is a linux server which is accessible by both my laptop and that XP pc.

To enable a Remote Desktop Connection, first I must log in to the linux server using Putty.exe via ssh connection. Set tunnelling in putty like this,

L1234 192.168.200.10:3389

From my laptop, connect to XP pc with Windows Remote Desktop application to 127.0.0.1:1234


Note :
The key is not to configure using the same port number 3389. In this example, I use port 1234.

Streamline SATA driver for HP CQ40

I am trying to install win XP on a HP CQ40 laptop which was actually build for Vista.
First problem is that it will not be able to detect a SATA hard disk. You can try to disable SATA in BIOS but my CQ40 does not come with that option.

I had to download a SATA driver and then try to integrate it into existing winXP cd. A process called streamlining. Need to have:

1. SATA driver file
2. nLite program
3. WinXP CD
4. blank CD and an ISO burner software

SED-insert quotes symbol

SED (stream editor) is a program to replace text in a file. Its easier to use VI, but sometimes, VI program is not available. Like in my case, I logged into z/Linux Server from Mainframe z/VM panel. I cant login remotely via SSH because network conf file (/etc/sysconfig/network/ifcfg-qeth*) is missing an important " symbol.

IPADDR="192.168.1.233

Typical SED command. Example to change ip from .233 to .234
sed -i ifcfg-qeth* -e 's/233/234/g'

but to add symbol " will not work straight away because ' and " is part of SED input.

Solution : use " twice, like this.
sed -i ifcfg-qeth* -e 's/233/234""/g'

Result :
IPADDR="192.168.1.234"


Thanks to Wan Uni Azran for helping me figure this out!
