No such errors are logged by amanda's own tools on that machine. I just
spent over an hour reading thru them after grep failed to find an error
or or fail in the lot of them.
ip a output looks normal after a reboot. But its offline as soon as
amanda starts. Firewall rule? I haven't run iptables on any of these
machines since forever but with systemd taking over, I've no clue how to
disable it if it is running. htop see's nothing that looks like
iptables, has it been renamed?
Thanks
