[mythtv-users] MythBuntu Frontend Not Connecting (Unknown socket closing)

[jmk]

Hi,

I recently had a failing drive in my Gentoo-based Myth backend. I've
purchased replacement drives and decided to just build a new Ubuntu
Server 10.10-based backend on them. I've installed everything and
imported a dump of the previous MySQL database from before the drive
crash. The backend now starts fine and my Mac and Gentoo frontends work.
Unfortunately, my MythBuntu primary frontend will not connect.

Both the Ubuntu Server and MythBuntu hosts are running the same version
of Myth:
MythTV Version   : df2d58b
MythTV Branch    : fixes/0.24
Network Protocol : 63
Library API      : 0.24.20101129-1
QT Version       : 4.7.0

On the backend, I see only the following logged when the MythBuntu
frontend connects:
2010-12-11 14:49:27.095 MainServer, Warning: Unknown socket closing
MythSocket(0x7f101c0ddf20)

On the frontend, I see:

I've initially tried alternate LocalHostName values on the frontend,
thinking a "new" frontend may have better luck. I'm at a loss why the
other two frontend ends function fine, but this one will not connect.

Any suggestions?
Thanks,
Joe
