No network on freshly installed Debian
First, get the list of recognized interfaces with an /sbin/ifconfig -a
.
If you don't see any eth*
interfaces, and you have an Ethernet adaptor installed, it wasn't detected. These days this is quite rare unless you have a card needing a firmware image to be loaded.
Assuming you find an eth0
interface, you want to issue an /sbin/ifconfig eth0 up
to bring it up. Then a dhclient eth0
to get an IP via DHCP. If you want to set an IP address manually it's /sbin/ifconfig eth0 {ip address} netmask {net mask}
; you'll also want to edit /etc/resolv.conf
to point to your DNS servers (use 8.8.8.8 and 8.8.4.4, which are Google's public DNS servers, if you are in a pinch.)
apt-get
and all that should work now.
Next, type man interfaces
which will explain how to edit /etc/network/interfaces
and get Debian to do all this automatically for you at next reboot.

I installed Debian Squeeze (using the cd1 image) without an Ethernet cable plugged in, telling the installer to "configure later" the network.
Now, when I boot, I have no network manager nor
ifconfig
(if I type that command in a terminal it replies:command not found
, except as root where I see alo
interface).How should I enable the network?

ifconfig
is/sbin/ifconfig
which isn't in a user'sPATH
on Debian. You will need to call it with the full path as a user. -
