|Re: [PLUG] Endian firewall - was Swapping motherboards|
Any Endian firewall gurus? Per below, I replaced the motherboard in my
Endian firewall, which runs RHEL. I tried to do a recovery from the original
media, but that package does not seem to provide a recovery option.
So no great loss, I have the weekly backups. I reloaded from the original
2.5.1 install CD, and could talk to it over the green network connected to
the native LAN port on the Atom motherboard. I also have a two port PCI LAN
adapter for the other two legs, which is unchanged after swapping
motherboards, so the only LAN adapter with a different MAC address is the
one on the motherboard.
I had no problems restoring the configuration from the backup, however after
I do I can no longer talk to the firewall on any LAN port. Where, for
instance, is the interfaces file that is under /etc/network on Debian
Any other ideas?
You'll want to boot from the install media into rescue mode. That will give
a root prompt with the on-disk system mounted under the /mnt/sysimage/
directory. You should then be able to run something like:
# chroot /mnt/sysimage/

I had an Atom motherboard die and replaced it with a slightly later
Atom board, both dual core and only slightly different in

error to the effect
mkrootdev UUID . Not found
Followed by a bunch of mount errors. The boot device is a SATA SSD. Is
it the fact that the UUID of the SATA port has changed? Can I replace
it with the current UUID, and where would I find it?
The OS is RHEL, not that it ever gets that far.
