Hi. On a Dell 4400, 1.6ghz pci based system which has two ethernet cards installed, running 32 bit FC5 latest kernel, 2.6.17-1.2139_FC5, I have the following emergency. (This machine was upgraded from FC4 to FC5 yesterday and was rebooted yesterday, a-ok, before the current problem struck.) My config did NOT use eth1 (was deactivated), only eth0, and was the only nic physically connected to the router. Tonight after a reboot, this cpu ceased seeing the lan, and others coudn't ping it as well. Fiddling around in back of the machine I noticed that the eth0 card was loose in the socket. I brought down the system, re-inserted the card, but still didn't work. So, I assumed that maybe the card burnt out since it was loose. No sweat, I thought, that is why I have the spare nic. I ran the networking applet, deactivated eth0, activated (and plugged in) eth1, tried service network restart, it showed eth1[ok] but.... no bytes, 0, nadda. Same after a reboot. I then copied /etc/sysconfig/networking/devices/ifcfg-eth0 over to ifcfg-eth1, UNPLUGGED eth0 from the router, set the ip address in eth1 to the same as eth0 had, rebooted but still -NADDA-. The queer thing is that it insists the both eth0 and eth1 are active, regardless as to how I set it via the applet. (It reverts to active.) Fwiw, I do NOT have the NetworkServices daemon active. Hopefully I missed doing something elementary. Your help is mostly appreciated. -nat
SOLVED!! I suddenly remembered that a long time ago, when I had network problems, I SHUT DOWN the ROUTERS, after changing nics (or whatever it was then). So, this is what I did now, and voila! Thank you all, and hope this helps. -nat ps. um Forgot to methion I also turned the routers back on<g>.
