| Summary | 0003822: Network card order naming | ||||
| Description | This problem isnt specific to CentOS, its the Linux kernel itself. Linux really have to set a standard how to name network cards. Right now the first card that is found is named eth0 and 10 ns later, one more card is found, and its named eth1. 14 ns later, one more card is found and its named eth2. If the computer is rebooted, the card that was eth1 might be named eth0 and eth1 will be named eth2. And eth0 will be named eth1. As you understand, this is a problem. So pretty please, with suger on top. WAIT until ALL cards are detected. THEN name them. IN THE SAME ORDER ALL THE TIME. It doesnt matter what order. Just do the same all the time. AND NEVER CHANGE THAT UNTIL THE UNIVERSE CEASE TO EXISTS AND MANKIND DIES :) I have seen this problem so many times during the 10 years I have worked with Linux. COLD reboot, eth0 is eth0 and eth1 is eth1. WARM reboot, eth0 is eth1 and eth1 is eth0. Or whatever. ITS ANNOYING. It doesnt happend with every computer or all the time but it does happend. Its time to solve this. It doesnt get more funny than this. My BGP router/gateway/firewall computer with 3 network card has exactly this problem. COLD reboot gives a specific network card order (the wrong one!) and warm gives and other. Warm reboot gave a random network card order before this; rmmod e100 rmmod e1000 sleep 1 modprobe e1000 modprobe e100 fix in rc.sysinit directly after "Start up swapping". It took like 6 hours before I realized that its the only workaround that will work. Nothing else helped. Its NOT funny to reboot a BGP router all the time, the world will not be happy. I pulled the plug so I wouldnt annoy the world however. This is intel network card specific but the problem is deeper than just intel network cards. 1. WAIT until ALL cards are detected. 2. THEN name them. 3. IN THE SAME ORDER ALL THE TIME. 4. ???? 5. PROFIT!!!! | ||||
