Tip: Resolving ethernet (eth) detection issues using udev in Debian Lenny
Purpose: This post is an update to one my previous posts which talks about how to resolve issues with your network/ethernet (eth) interfaces in Debian Etch. Basically the technique to resolve in Debian Lenny is almost the same as mentioned in the previous post. The only thing that changed in Debian Lenny, because of a newer version of udev package, is the names of the file to delete.
Note: Debian Etch (4.0) users click here. Debian Lenny (5.0) users please continue reading…
Before you read any further I highly encourage you to read the previous post to under what kind of problem are we talk about. Basically from Debian Lenny onwards you delete the following two files instead of the “25_persistent-net.rules” and ” z45_persistent-net-generator.rules” files
Just delete the following two files by giving the commands:
# cd /etc/udev/rules.d
# rm 70-persistent-net.rules 75-persistent-net-generator.rules
Now restart your system and your network/ethernet detection problems should go away!

Very useful tip, specially every time you clone a Debian installation to another machine (or virtual machine, i.e. “vboxmanage clonevdi” in VirtualBox). Thanks you!
