One of my CentOS 5 server was mistakenly installed Desktop Environment (GNOME) during the OS installation. Most of the time, i just use Command Line (CLI) to manage the Centos Server. So, i decided to completely to uninstall it in order to save some Hard Disk.
Before you remove all the GUI package, please disable GUI first. It is because after you remove the Gnome and X Windows, CentOS will still try to load X Window. If you want to prevent the GUI from loading but want the rest of the system to load as usual, you need to make a change to “/etc/inittab”. Read the rest of this entry »

Recently i just change to new Mac machine. I would like to transfer SSH keys from my existing Mac machine to my new Mac machine instead if generating new SSH key for my Mac machine.
Now i going to show your how to move SSH keys from my existing Mac Machine to my new Mac machine.

For example using rsync command to transfer SSH key from existing Mac to new Mac machine.
The easier way is using the Finder to copy the SSH keys. First you’ll want to show hidden files in OS X open up the .ssh (~/.ssh) directory on existing Mac machine and backup .ssh directory to your external drive. After that, you just need to transfer the .ssh directory that you already backup to your new Mac machine on ~/.ssh directory.

I just brought new MacBook Pro. I plan to replace the existing SATA Hard Driver with an SSD (Solid State Drive) in order to get better performance of my MacBook Pro. By replace the Hard Drive with an SSD, my Mac will boot faster, copy files in the blink of an eye, and make the system more responsive when multitasking.
To change the Hard Drive in MacBook Pro, it’s fairly easy to do it. Below is the video clip to show you how to do it:-
