Hi,
I recently made several changes to my network, and ever since my bacula backups
to the affected server error out after exactly 15 minutes. I don't know exactly
which change is the culprit, but I suspect it is somehow IPSec-related, and
would appreciate some help troubleshooting the problem.
I have servers in two locations: my main office with the bacula director and
SD, and several clients, and two remote servers in a data center 2000 miles
away. These servers only run the bacula-fd.
The director used to use SSH to connect to both remote servers, and this worked
reliably.
Recently, I implemented IPSec to one of the two remote servers. Director,
remote FD and SD can now connect directly to each other, without any other
tunnel (logically, IPSec is transparent). At the same time, I also switched my
Internet connection from Cable modem to DSL. The second server still uses the
SSH tunnel to do the backups.
Unfortunately, using IPSec, the backups seem to fail after 15 minutes; the
connection from FD to SD seems to get severed. The backups to the second
server, using SSH, work without a problem.
The director produces this log output:
