Re: DHCP and domain name
Actually, I got that in /etc/network/interfaces:
# The primary network interface
auto eth0
iface eth0 inet dhcp
So, it looks like at the start of the system, it run a DHCP request. It's strange...
For the question 2), I meant that if you do a DHCPREQUEST, the dhcp send you, in the DHCPACK, a domain, I just wanted to be able to access this value, if it's stored somewhere.
For the question 3), I wanted to know why the command "hostanme --fqdn" returns me:
localhost.localdomain.
I found out that it was the value stored in /etc/hosts.
But the problem is still there, I don't know why there is this value in /etc/hosts and not something like debian.mydomain with mydomain equal to the value that the DHCP gave me at the beginning (cf 2)).
Thanks for the answers.

Assume "less /etc/network/interfaces" shows you something where you
can see...
iface eth0 inet static
address 192.168.0.72
netmask
255.255.255.0
gateway 192.168.0.1
...which means that whenever your system boots up your computer will
have 192.168.0.72 as its IP. If you do a "dhclient" as mentioned above
you probably get a new IP from some DHPC-Server somewhere in your
network.
Maybe this is what is going on on your system.
I did not understand what you meant in (2) and (3).
Cheers
Sam
