Since yesterday, my IP resets every 2-3 minutes and I have to repeatedly add "ifconfig eth0 192.168.xx.xx" and "route add default gw 192.168.xx.xx" to it to keep it running. Can't seem to find the solution after a few google searches. Any one has any idea what's wrong? I have dual boot and windows xp is working just fine on the same lan. -- TopBot. <fieldset></fieldset> </blockquote></div></div> Hi, I have had a comparable problem from W7. In my case I had IPV6 and IPV4 both open, which was causing the problems. As soon as I had only one open, I had no problem. I am not saying this is your problem, just something to look at. The other thing is, that a change in computer behaviour is always the result of a change in the configuration or software. You might want to retrace your steps and find out what you or the system changed in the past few days. Could easily be an (automated) update somewhere. P.S. are you posting for Kubuntu or ubuntu? Crossposts are often not appreciated. I removed the ubuntu address from my post. <div>-- Kind regards, Guus Bonnema.</div> </div> </blockquote></div> Here's what the IP resets to (settings before and after the reset respectively): root@bt:~# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:1a:92:95:81:ca inet addr:192.168.93.92 Bcast:192.168.93.255 Mask:255.255.255.0 inet6 addr: fe80::21a:92ff:fe95:81ca/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:34391 errors:0 dropped:0 overruns:0 frame:0 TX packets:18367 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:15099569 (15.0 MB) TX bytes:4144722 (4.1 MB) Interrupt:20 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:8203 errors:0 dropped:0 overruns:0 frame:0 TX packets:8203 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:491832 (491.8 KB) TX bytes:491832 (491.8 KB) root@bt:~# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:1a:92:95:81:ca inet6 addr: fe80::21a:92ff:fe95:81ca/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:41153 errors:0 dropped:0 overruns:0 frame:0 TX packets:22356 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17502811 (17.5 MB) TX bytes:4992366 (4.9 MB) Interrupt:20 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:8398 errors:0 dropped:0 overruns:0 frame:0 TX packets:8398 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:502020 (502.0 KB) TX bytes:502020 (502.0 KB) ...settings are lost/initialized after the reset I think. My lan uses switches and a server which is connected to the main server; our IPs are static on the lan with no restrictions. All my auto updates are off and I did not change any settings. It just started to happen since a day ago. Yes, I posted to both lists (I'm subscribed to both), my bad if that's not the norm here. -- TopBot.
