Unhappy Internet stopped working


Slackware 11
2.6
Comcast

It worked up until 06/03/07 then nothing.

I have two Ethernet ports on an Asus A7N8X Deluxe MB.

ETH0 is connected to cable modem
ETH1 to LAN

ifconfig eth0 up activates ETH0

dhcpcd -d eth0 up times out and ETH0 does not show up with an ifconfig

It works fine under WIN XP duel boot for some games and other Win junk.

Any ideas where to look. Nothing really strange in the logs I am stumped

For some games? so it works only some of the time in windows as well or all the time? do you ever time out surfing the web in windows? in linux, when you try to dhcp, have you tried rebooting the cable modem before hand? im also guessing that you are making linux act as a firewall and supplying dhcp to other pc's on your network? do you remember installing anything around the time it stopped working? have you tried to get it working using the other NIC?

No it always works under Windows. I have IP masquerading and forwarding set up and I made no changes to the Linux setup. I have not tried it with the other NIC. It just stopped working. Strange. I guess I should disable the IP masquerading and forwarding and see if that is the problem. I don't see why that would break it as I did not change anythig Yes I did try rebooting the modem.

The darn thing just started working again on it's own with no intervention by me I think it has something to do with the DHCP lease. I think COMCAST renewed the lease while I was in windows and the Linux lease had not expired. There was a service disruption and I think that this was the cause. I probably could have deleted the lease and renewed it and that probably would have fixed it. Am I way off base here or is this a possiablity?

usually when you reboot the cable modem it releases and renews. however i don't think you are too far off. i've noticed that on my ipcop router when and in that day i've dual booted to windows and linux in one of the stats page it shows 2 of my pc's. for some reason it see's my linux box as a different pc even though same mac and ip for my nic. really odd.
anyways, glad you got it working.

I've had similar problems with my setup, but by switching all my computers to static IPs, but leaving DHCP on, seemed to solve any problems. The DHCP catches any computers that i am reinstalling the OS on, or friends laptops.

I find that if the network isn't working, the best thing is to reboot EVERYTHING. This usualy works for me.

I am glad everything is now working for you

Yes I guess I wont know for sure unless it happens again. I thought there for a second that Comcast had gone all medieval on Linux.

Hum I have to delete /etc/dhcpc/dhcpcd-eth0.info or it does not work. There has to be something off somewhere. I just don't know where I got to fix this or at least figure out how and why it went south

Now it does not seem to work at all. I need a dhcpcd expert as I don't seem to find anything that makes any sense to me.

I reinstalled Slack and now it's working again. There did not seem to be anyway to get it to work. I know that is incorrect but I just got fed up with it. Now I have to see how much of my system is still intact as I just did an install over top the old one since it was the same verison of Slackware.

Do you need dhcpd?

What if you manually assign your IP, Gateway, DNS? (/etc/rc.d/rc.inet1.conf /etc/resolv.conf)
