Well that me realize that if I ifconfig while pinging shows the interface as up, I have an IP . . . if I do it while the interface is down, I have no IP. Maybe it's the DHCP server? I'm going to try using static IP and see if that works . . . .
IMHO, it is due to the fact that the iface is getting an IP address according to the zero conf standard by the OS... I do not remember exactly in which range... But I think it is the expected behavior.

Here, if you compare with the loopback interface, you can see that the *inet* and *Mask* field are missing...
I think you've forgotten to give a IP address to the network interface:
$ ifconfig eth0 <ip_address_of_the_interface>
It should solve your problem.
Hope it helps.

Well, I tried setting it to static, and that didn't work. It got the IP, worked for a while . . . and then stopped. Still. Grrrrr.
As a temporary solution, I made a script:
while [ true ] do if [ ! "`ifconfig eth0 | grep 'inet addr'`" ] then ifconfig eth0 192.168.1.115 fi done
And that sort of keeps it up, but it's about the stupidest solution possible. Not even a solution, really.
I would suspect that it has something to do with the card itself, but it works under Windows 98, and I find it difficult to believe that it would work better under Windows 98 than GNU/Linux ;)
If anybody has other suggestions / magical solutions / whatnot, that'd be grand :)
