I updated motherboard on x240 computenode, now the ethernet interfaces show up as eth2 and eth3 previously it was eth0 and eth1.
I tried to delete /etc/udev/rules.d/70-persistent-net.rules file but the problem still persists on bootup it says that eth3 and eth2 cannot be recognized or mapped. The new mac addresses are clearly illustrated and mapped to name file eth2 and eth3.
I did change in file ifcfg eh2 and eth3 and change its name to eth0 and eth1 respectively. But this too had little effect, do i need this change to be done in 70-persistent file as well. E.g change name filed to match the entry in ifcfg?.
Is there a way i can bring the old mapping back? Thanks.
