2. I just get confused in app names in Synaptic and want to install apps without using DVD easily.
man apt man apt-getTo install from network you have to modify /etc/apt/sources.list with (if you using debian stable):
deb http://ftp.us.debian.org/debian stable main contrib non-free deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free deb http://security.debian.org/ wheezy/updates main contrib non-free next do: apt-get update
It would be great for this newbie to be properly guided.
