Hi Y'all,
We have two RHEL 6 servers, one is running bacula-dir and bacula-sd
(with a lot of disk storage for the backups), and the other is the
client we want to back up from running bacula-fd.
Both servers are behind different firewalls, and each has a public IP
address that is configured for 1:1 NAT to the internal server. I can
telnet from the director to the client on port 9102 and connect OK, and
the client can telnet to the storage daemon on the other server on port
9103 and connect OK. So, I think the network path is working.
What appears to happen is that we start the backup job, and it connects
and begins transferring and then almost immediately stops and then times
out. It transfers like 800 bytes and seems to just sit there. This is
what it looks like on the different status reports from bconsole on the
directory node:

So, the storage says it transferred 52,038 bytes almost immediately
after the job started and then transferred no more, I check for a while
after. Sometimes it tranfers only 800 bytes then just waits.
Eventually the job times out with:
15-Jun 02:00 bacula-dir JobId 15: No prior Full backup Job record found.
15-Jun 02:00 bacula-dir JobId 15: No prior or suitable Full backup found in
catalog. Doing FULL backup.
15-Jun 02:00 bacula-dir JobId 15: Start Backup JobId 15,

It *does* seem like the FD can connect back to the DIR and SD, so I don't know
why it would stop transferring immediately after starting and then eventually
time out. I've confirmed my firewalls are not timing out the connections. I
also have "Heartbeat Interval = 60" in the SD, DIR and FD config files. But
the reason I don't think it's a firewall timeout is because it almost
immediately stops transferring after only like 1 second.
Anyone have any ideas as to what is happening?
Thanks in advance!!
