Something like this happened to me just a few days ago. I bought two identical motherboards, but only 1 CPU (awaiting a free CPU from a friend). I wanted to test both mboards right away, in case any of them was dead. I built a machine around the first mboard, and then installed Lenny using a daily-build Debian-installer CD from March. It all worked fine, including the NIC being autodetected as "eth0", etc. Then, I swapped in the other mboard. All worked just as well, except the NIC didn't seem to be detected. Upon closer inspection, I found (via 'dmesg | less') that the kernel was seeing it just fine but udev was renaming the NIC from "eth0" to "eth1". The problem turned out to be relatively simple. A list of devices discovered by udev is kept in /etc/udev. The MAC address of the NIC on the first mboard was stored in a "persistent rules" file there, and udev has been written to assume that any device it discovered in the past may suddenly reappear someday. In short, udev was preserving the "eth0" name for the NIC from the first mboard, and was assigning "eth1" to the NIC on the second mboard. This sounds very similar to the problem you are having! ;) My advice is: 1) Go to /etc/udev/rules.d in a terminal. 2) Run 'grep eth *'. (In my case, the file I found with the problem was called 'z25_persistent-net.rules'.) 3) Use your favorite editor (as root, or with 'sudo' or 'su -c', etc.) to alter the configuration to your liking. In my case, I commented out the line that was assigning "eth0" only to the MAC address of the NIC on the first mboard, and then edited "eth1" to "eth0" on the line identifying the MAC address of the NIC on the second mboard. 4) Run 'ifup eth0'. In my case all was well. HTH, Dave Witbrodt -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
