Re: Can't get network to work

Problem:
On a fresh install of Debian 3.0r3 Woody (2.2.20-idepci kernel) off the
.iso from the server, the neworking doesn't work.  I'm on an AMD Athlon
with a 21140-based on-board ethernet chip (lspci and WinXP both say so)

SO I KNOW IT CAN WORK.

HOWEVER, after booting, eth0 is only configured for a 192.168 address,
NOT what the dhcp in my dsl modem should be giving it.  I run ifup eth0
and I get a series of "SIOCSIFADDR: No such device" errors.  Ditto if I
run dhclient directly.

Again, more research, and I am told to type, "modprobe tulip".  Ok, now
there is no error. (apparently, insprobe pci_scan and then insprobe
tulip does the same thing)

I type, "ifdown eth0" and then "ifup eth0", and nope, still the same
SIOCSIFADDR errors.
I added 'alias /dev/eth0 tulip' in the /etc/modutils/aliasas file and then ran update-modules. /etc/modules.conf has this entry. Reboot, and same problems. 

During boot, it appears to find the nework card just fine (tulip.o comes
up, and lspci gives all the details about the card). Also, the
SIOCSIFADDR messages are repeated there as the dhcp tries to come up. Then during modprobe in boot it says "Can't locate module eth0:0", with a bunch of IO types errors (all-caps). 


For networking in Debian, you need to be concerned with four basic things:
1) Inserting the correct module - "modprobe tulip" should do this on a boot-by-boot basis. Adding "tulip" to "/etc/modules" should allow the system to handle this step automatically.
2) Your "/etc/network/interfaces" file needs to be correctly configured for static/dhcp. "man interfaces" will give you more info; Ron's suggestion is accurate for DHCP.
3a) If using dhcp, you need to install a dhcp client, such as "aptitude install dhcp-client" or similar. 
3b) If using static, you need to configure "/etc/resolv.conf".

4) [Re]start networking. "/etc/init.d/networking restart".
As I've never had to add anything to "/etc/modutils/aliases" for a first ethernet card (and am not quite familiar with it), I'd first try removing that entry you made and then add "tulip" to "/etc/modules" and then reboot.
