Have you done a packet trace on the bacula server? May be (guessing here) as a part of the upgrade that host-based firewalling got enabled?

Lars,

    Well, truth be told, I was doing this locally on the server. For sake of experimentation, though, I ensured bconsole.conf was proper on my desktop, and ran bconsole while doing a trace.

    All that happens, is five packets:

47902 > bacula-dir [SYN]

    Server acknowledges:

bacula-dir > 47902 [SYN, ACK]

47902 > bacula-dir [ACK]

    Client responds with call to director:

47902 > bacula-dir [PSH, ACK]

0000 00 24 81 f8 08 08 00 1d 92 b6 98 70 08 00 45 00   .$...... ...p..E.

    Server Acknowledges...then, nothing happens at all after this:

bacula-dir > 47902 [ACK]

0000 00 1d 92 b6 98 70 00 24 81 f8 08 08 08 00 45 00   .....p.$ ......E.

    So what's puzzling here, is that the server is listening and even responding, yet it seems like it's hung on the response for some reason. That, or perhaps there's some communication problem in the package of bacula-console I'm working with, both in ressu's 3.0.2 and the original 2.4.4, with this director.

    I may have to go back to 2.4.4 sadly, if I can't fix this - which would bring several other bug investigations back to a standstill. I am currently using ressu's PPA on this .deb package. I will try to switch to the current unstable Ubuntu development repo's, see if maybe that package is happier, but, I still can't resist the urge to find out what's really going on here...
