Installing GNS3 in Ubuntu 12.04 LTS X64

As i have read from several blogs Linux performs a bit better than Windows. Then I started to install variety of Linux OS on my desktop dual booting with Windows 7.

Till I decided to keep my desktop case open and switch the SATA cable manually to my two HD one with Win7/Windows 2003 Server and one HD dedicated to Linux. So far I feel more comfortable with CentOS then later i find out that i could change Ubuntu Unity to the old Gnome Desktop. I decided to stick to Ubuntu as most applications I frequently utilized is easy to install via Ubuntu Software Center.

There are still cases that I could work faster on some Windows application since i just started to learn Linux. I started to keep some notes online as I'm frequently reformatting my hard disk. This is the first one you might find it useful if you want to try GNS3 on Linux.
