Package: amanda-server
Version: 1:3.5.4-2
Severity: important
Dear Maintainer,
After upgrading from bookworm to trixie, any unreachable DLE accessed
over ssh will cause the planner to fail and the whole amdump job to fail
with MISSING status for every DLE.
Removing all offending DLEs from the disklist will let the amdump
proceed correctly, including dumping DLEs reachable over ssh.
From that known working config, consider the following:
- Re-adding a single DLE for a host that is unreachable will again cause
the planner to fail and the whole amdump to fail, with every DLE
reporting MISSING.
This is a regression from bookworm.
- Adding a DLE for an unresolvable hostname, with a bsdtcp dumptype will
correctly report a problem with that DLE only, the amdump will proceed
as expected.
- Switching the dumptype of that unresolvable hostname DLE to one with
auth=ssh will again cause the planner to fail and the whole amdump to
fail.
Those last 2 steps should provide an easy way to reproduce the bug.
end of the planner debug log:

Additionally, amcheck will exit early with a disklist containing
problematic ssh DLEs, without correctly reporting the problem. It will
not output any "Amanda Backup Client Hosts Check" section, though the
error "ssh: Could not resolve hostname failure-host: Name or service not
known" will be in the server host check section.

Switching the offending DLE dumptype to a non ssh type will correctly
produce the following output:
Amanda Backup Client Hosts Check
--------------------------------
ERROR: failure-host: selfcheck request failed:
resolve_hostname(failure-host): Name or service not known
It will also report problems with other clients, which it didn't when
the problematic failure-host DLE was type=ssh.
