[coLinux-users] Help need with udev: renamed network interface eth0 to eth2

[Frank C. <vfc...@go...>]

I installed an ubuntu Gutsy and later upgraded them to Hardy Heron,
but it seems that some of the networking settings carried over, and as
I have to run them all at the same time I just want to make sure the
problems don't happen again. I am afraid to reboot them in case they
lose their settings.

I have used the info in this link
http://colinux.wikia.com/wiki/Wubi#udev:_renamed_network_interface_eth0_to_eth2
to fix the problem temporarily, but I am not sure what mac addresses
they will be given if I reboot them. I just want to have a way of
ensuring that the interfaces are given unique mac address when they
restart.

These are the current ifconfig settings and the contents of the
/etc/udev/rules.d/70-persistent-net.rules, they are all derived from
the same image.
