Hi
I want to backup some cluster that needs a script to know what
machine is the master. So this mean that i can not use the
ClientNameAlias directly, but i'm using it to define the cluster name
so i can use more freedom for the backup name.
As backuppc uses the netbios if the dns fails, I'm trying to
"abuse" the NmbLookupFindHostCmd and by running manually i can see it is
working... the problem is that via backuppc, it then tried to do the
reverse NmbLookup for that IP and of course, it fails. As the $host in
NmbLookupCmd is the IP, i can not know what cluster it should return for
the reverse lookup. So the end result is the error:
"Dump failed: host clusterA has mismatching netbios name"
So is there any workaround for this? What other people that
need to get the host by a script do?
@Craig Barratt: How about adding a option to disable the
reverse netbios lookup?
Thanks

I do something similar. The key is to set $Conf{NmbLookupCmd} to empty string. There is a condition in BackupPC_Dump that checks $Conf{NmbLookupCmd} eq "" and returns without doing the mismatch check.
Now that I think about it, this might be a bug. $Conf{FixedIPNetBiosNameCheck} reads like it's supposed to control whether or not to perform this check. The entire condition reads:
return if ( $hostIP eq $host && !$Conf{FixedIPNetBiosNameCheck}
|| $Conf{NmbLookupCmd} eq "" );
I think that && should be a ||
