Network error after MAC address change

Added about 2 years ago

After an hardware crash on hypervisor (VMWare, Hyper-v, KVM) all the network parameters are unset.

This is reproducible all the time when the MAC address of the MailCleaner change.

Udev store network informations in files (/etc/udev/rules.d/).
One of them are the persistemt rules which match network interface and IP with MAC address.

So if the network interface MAC address change, we have to remove the old MAC address assignation :

  • log in on the MailCleaner console as root
  • edit udev file : /etc/udev/rules.d/70-persistent-net.rules
  • remove the line containing the NAME="eth0" string
  • restart the MailCleaner
