How can I set the domain name in GNU/Linux?, I am using Crunchbang and I need to set the domain name for my LAN network.
EDIT: Let me talk more about my problem: I need to configure a LAN network for three or four PCs with GNU/Linux(college project):
PC1: acting as server -- hostname = "server" -- GNU/Linux Debian Squeeze PC2: client 1 -- hostname = "crunchbang" -- GNU/Linux Crunchbang PC3: client 2 -- hostname = "acer" -- GNU/Linux Debian Squeeze
Crunchbang is based on debian then "I think" there is no much difference.
I am guiding me with this document and there says that the domain name for all hosts in the network must be the same.
The OS in PC1 and PC3 are fresh installations, Crunchbang is the OS what my friend have in his laptop.
When I installed debian in PC1 and PC3 I set the domain name and the host name but now only the last is present.
