That sounds a ton like the problem I am having. I had originally configured mine to act as a server, thinking "I might like to put some things on the web, and it would be convenient to have them straight in my linux box." I too have a firewall, and I too suddenly experienced the internet going down.
More than that -- if I try PING to my next link, it doesn't work. But if I reboot into Windows, everything is fine. Well, sort of. I think that one of these times I took my ISP's network down, and it stayed down until someone rebooted *their* system. Aside from that, Windows internet still operates (same computer) but Linux' network capability has progressed to being completely down, all the time. The guys at the ISP think that the problem is a configuration problem of some sort. But they did allow for the possibility that it could be some kind of a virus, perhaps. Let me ask you -- assuming that it is something having to do with the internet server or the firewall -- what programs would I have to uninstall to get rid of both the internet servers and the firewall, and all their support systems? I just ran ifconfig, and got back no collisions. eth0 Link encap:Ethernet HWaddr 00:E0:7D:78:55:D8 inet addr:192.168.13.1 Bcast:192.168.13.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:18 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:1084 (1.0 KiB) TX bytes:180 (180.0 b) Interrupt:10 Base address:0x1040 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:3924 Metric:1 RX packets:80 errors:0 dropped:0 overruns:0 frame:0 TX packets:80 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5207 (5.0 KiB) TX bytes:5207 (5.0 KiB) sl0 Link encap:Serial Line IP inet addr:192.168.13.1 P-t-P:192.168.13.254 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:10 RX bytes:0 (0.0 b) TX bytes:252 (252.0 b) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
