network setup from command line

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.

Code:

---

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:

Code:

---

# 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:

Code:

---

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