HI there
I have an issue where BackupPC can't backup some hosts anymore. Let me
explain
* I backup a bunch of servers behind bastion hosts. SSH tunneling is
configured in ~backuppc/.ssh/config
* Some of the host behind the bastion do not have a corresponding
public DNS entry published
* For all of my hosts, the name of the machine is meaningless. It's
something like client1_machine3. The DNS name is always set in the
ClientNameAlias
* For host behind a bastion, I change the PingCmd to $pingPath -c 1 -w
3 bastion.host.net so the bastion is pingued and its latency can be
checked
Until now, I had a wildcard DNS CNAME entry for the domain of my backup
servers, which made everything working. But as I'm changing the backend,
and don't want a wildcard (* IN CNAME foo.bar) entry, I'm now facing the
issue that, hosts behind a bastion, without a corresponding DNS entry
won't backup anymore. The error is
2018-11-23 08:59:53 Can't find host ldap.client1.fr via NS and netbios
2018-11-23 08:59:53 can't ping (client = client1_ldap); exiting
Of course it can't find it, and it doesn't need to because everything
will be done through an ssh tunnel, defined in .ssh/config.
With my previous setup, it would have looked for ldap.client1.fr, and
wouldn't have an anwser, and then, it would have looked for
ldap.client1.fr.firewall-services.com which would get caught by the
wildcard entry, and then, the backup could run. But the DNS answer
itself was meaningless, and not used at all.
Is there a way to disable this lookup for such cases ?
Regards, Daniel
