gnome-desktop

[Gunawan]

Hi,
Again I would like to learn.
Though I have successfully install squid and shorewall
sudo apt-get install squid
sudo apt-get install shorewall
both program install from the cd.
I would like to know how to change the package so ubuntu will read.download 
package from internet.

because if I run this command
sudo apt-get install gnome-desktop
it will say package not found.

I have add
http_proxy=http://myproxy:port
ftp_proxy=ftp://myproxy:port

because myproxy require windows domain authentication I add my user

http_proxy=http://DOMAIN\user:password@myproxy:port
ftp_proxy=ftp://DOMAIN\user:password@myproxy:port

Can I install additional software for my ubuntu server from the internet?
Regards,
Gun
