can not get out

aleskx · Posted: Thu Jan 08, 2004 4:11 pm Post subject: can not get out

new to Gentoo... everything looks ok, but I can not access network. I have installed Gentoo and I know that my network card works because portion of install came from various remote sites ... plus I have replaced the card physically while trying to resolve this - it is definitely not hardware

gentoo machine ip is 192.168.26.158, the other machine is 192.168.26.157(WinXP), alive, networked and well

any help will be greatly appreciated.

here are my config files/diagnostics (commented lines removed for brevity):

I would say that it seems as if your gentoo box is connected fine, but only the windows box doesn't respond.

Are you running a firewall at the windows box? If so, you should make sure windows box doesn't reject "icmp" traffic, because that is what ping is. Ofcourse you could also just shut the firewall down briefly for testing.

Maybe there could be other other causes, but I don't know.

Windows XP has a built-in firewall that may be on. I don't think it is turned on by default, but you should check it anyway. If you don't know how to get to it, I think you can get there by going to control panel->Network Connections->Your connection->TCP/IP Properties->Advanced->Firewall or something. I am pretty sure that it is in the TCP/IP properties under adnvaced somewhere.

Can your windows box surf the net? Can it ping your gentoo box? If it can surf, but can't ping, try running an ftp server on the gentoo box and accessing it from the windows box. Or you could use telnet or ssh (putty works well in windows as a client) or any other server that doesn't use ICMP.

Look at all those TX errors on your ifconfig output. Are you sure you don't have a hardware problem? Have you tried swapping eth cables? What does dmesg say? Maybe try using the mii-tool, etc?

Hey,
Well you might not be entirely crazy... I'm having the same problem and I'm certainly not new to gentoo.

Are you using the 2.6.1 kernel? I'm thinking there might be something in there that is the problem, heres why:
-System w/ 2 network cards.
-On several 2.4.xx kernels, both net cards worked fine.
-Upgraded to a custom compiled 2.6.1-gentoo kernel.
-Now, neither net card works.
-The status and config of both cards seem to show that they are optimal. The only problem occurs when actually trying to send or recieve packets. (even mii-tool says they work fine).
-I have a network with 3 other computers, all working fine over a switch, of which I cycled the power just incase -- no effect.
-Reverting to a 2.4 kernel on a knoppix cd, I can use both cards again.

This suggests that:
1. It isn't a hardware problem
2. It isn't a problem with the individual net card drivers
3. Something else in the kernel is the source of the problem

So, its possible that I've compiled out something in the kernel that is needed (although I've been through the config twice and can't see anything). However, I think what I'll do now is just start adding a bunch of options back in to the kernel and see if any of them make it work. Otherwise, try a different 2.6 kernel I guess... Anybody have any other suggestions?

Thanks.
Brian

Just for giggles, what is the result of a traceroute to the windows box.
