Strange Network Devices after Linux Restore

Postby Rapajez » Fri Jun 15, 2018 10:34 am

All,

I have 4 Dell Precision 7720 laptops, all running Red Hat Enterprise 6.

I was able to create full backups to both external DVD, and USB Storage Drives without an issue. No issues backing up Laptop A, and restoring to Laptop A.

However, when I backup Laptop A, and restore to Laptop B, I end up losing my primary Ethernet interface "eth0". I somehow end up with a new interface "eth1". I'm trying to figure out where the configuration for the new interface is coming from. Nothing in /etc/sysconfig/networking-scripts; nothing obvious in /etc/udev.

Not sure where to start looking. Any tips?

Will provide additional information as needed.

If anyone else runs into this, I had to edit/remove the /etc/udev/rules.d/70-persistent-net.rules file before backing up.

This file contained the MAC address of the source laptop, and any laptop I restored to would think it had two devices (one from the source laptop, and one from the destination laptop).

whenever I've had linux networking issue with the NIC being found, generally
in a vm, deleting that file always seems to fix it up.
