network setup from command line

[bentaylor]

pretty new to linux, but have recently set up a server and (intentionally) haven't installed graphical components 'cos i won't need them.
The server hasn't got a network card yet, so if I just whack a cheap one in will it recognise it automatically?

And when I've done this, how do I then do all that business of telling it what it's ip address is, what the default gateway is etc from the command line?

Depends on your system. Probably.

And when I've done this, how do I then do all that business of telling it what it's ip address is, what the default gateway is etc from the command line?

ifconfig eth0 192.168.0.2 netmask 255.255.255.0 up
route add default gw 192.168.0.1

Or similar.

great, that works... how do I now set the default DNS server ?

Add them to /etc/resolve.conf and restart networking.
Mine is:

# Generated by dhcpcd for interface br0
nameserver 208.67.222.222
nameserver 208.67.220.220

i don't think it's saved it permanently as I just had to reboot and it didn't save...was back to 'network unreachable' when i booted up again.
How can I get it to permanently set the network settings, like do I need to store them in a file somewhere?
Cheers

On gentoo it's in /etc/conf.d/net:

config_eth0=( "192.168.0.3 netmask 255.255.255.0 brd 192.168.0.255" )
routes_eth0=( "default via 192.168.0.1" )
