Well with the new ION proxy authentication I was forced to change the my laptop’s name. I use windows 7 and UBUNTU 9.04 which the ION people obviously could not change. So I decided to change its name myself for the first time.
1. Open Terminal and then type
2. gksudo gedit /etc/hostname
3. gedit will open your computer name
4. change it and enter the regular proxy order(for MITians)
5. Your net will work.
6. Be thankful you wont need to restart your computer in linux as in case of windows
