its up and running as we speak ... im posting via eth0 ...

im also noticing very poor performance

Check and see if /proc/net/dev exists and is populated. That's where the information displayed in ifconfig comes from. If it's not there you probably need to go back through your kernel config and go back over your network options to make sure they make sense -- use the gentoo defaults as a guide.

Fix the ifconfig problem first so we can see if you are getting a lot of errors or something else that's obvious.

the slow side of things turned out to be a bad nic on the other machine ... this one is seeing no probs outside ifconfig being empty

I have been monitoring it with the nms and it shows no errors at all that way ... but the other box has some here and there

cat /proc/net/dev

88956 err's for that one

hrmm, not much to go on then. ifconfig isn't a huge or complicated program, so this has to be a disconnect somewhere. Changes to the kernel would seem to not matter, because the data is populated, ifconfig just isn't able to read it. Restrictions on reading /proc would be a possibility, but I assume that you've tried it as root and it has the same problem. ifconfig doesn't really depend on anything except glibc -- I guess it's possible there's a problem there.

Permissions on /proc/net/dev maybe? Version of ifconfig (it's in the net-tools package)? Any unusual kernel patches or mods? Version of glibc? Did either of you try re-emerging net-tools? Anyone not on x86?
