Many thanks to all the good people who replied. I agree with those who prefer editing text files to using (e.g.) linuxconf, but it's hunting down those files which is causing me trouble.
I put 3c59x into /etc/modules and that did part of the trick. Then edited /etc/network/interfaces so now eth0 is starting at boot. So far so good. I'm still not getting any packets out, though. I have nameservers in /etc/resolv.conf. I have *no idea* where to configure a default gateway. Do I need to do a 'route add'? Some documentation I've seen makes reference to "/etc/init.d/network" but that file isn't present on my machine. Furthermore, is there anything else I need to do to get a working 'net connection? Done: bring up interface, nameservers; doing: gateway. Thanks again, Randall
