Bugzilla Bug 125356

please see bug #102926 and bug #98428 for reference.
hpssd.py, even if started manually, does not run. However, there is no error
message. (Doesn't run when started by init.d/hplip):

stilgar ~ # /etc/init.d/hplip restart
 * Stopping hpiod ...                                                          
                                      [ ok ] * Stopping hpssd ...

 [...]
 6374 ?        Ss     0:00 /usr/sbin/hpiod

this causes the probe script to fail:
stilgar hplip # ./probe -busb

You cannot simply hardmask a working package (hpoj) just because there's a more
bleeding-edge one, if that one's not working. Can you?

hplip works for me.

You realize you posted your results after you tried to stop hplip? (but I see
what you mean though, if it was running in the first place /var/run/hpssd.pid
would have been created)

Anyway, dou you mind posting the output you get when you run
/usr/share/hplip/hpssd.py manually?

Exactly, there was no point in posting the output of start, because there's
none.
I wanted to show, that the process is not being started.

stilgar hplip # ps ax | grep hpssd

Indeed, it should show something like

10382 ?        S      0:00 /usr/bin/python /usr/share/hplip/hpssd.py

Can you run it with -ldebug? I was hoping to see some useful error message:
/usr/share/hplip/hpssd.py -ldebug

Have you tested 0.9.8-r2/contacted upstream about this? I can't really tell why
the daemon does not start for you (in case -ldebug doesn't help).

this is all I get in my syslog:

Mar  7 19:24:45 stilgar python: hpssd [DEBUG] Exception: 95 (Unable to bind to
socket)
Mar  7 19:24:45 stilgar python: hpssd [ERROR] Server exited with error: Unable
to bind to socket

And not really very informative. It says quite the same thing than probe does.

No, I've not yet tried 0.9.8, nor have I contacted upstream, although I've been
crawling through the official forums, with no luck at all.

Same thing happens with 0.9.8

I found what was causing the problem. Running hpssd.py with the -ldebug switch
returned the following:

May 12 20:30:58 stilgar python: hpssd [ERROR] Server exited with error: Unable
to bind to socket
May 12 20:31:24 stilgar python: hpssd [ERROR] Server exited with error: Unable
to bind to socket
May 12 20:31:50 stilgar python: hpssd [DEBUG] Exception: 95 (Unable to bind to
socket)
May 12 20:31:50 stilgar python: hpssd [ERROR] Server exited with error: Unable
to bind to socket

after a little googling, I found out, that this might be caused by a missing
127.0.0.1 localhost
entry in /etc/hosts and indeed, I had changed it to match my ssh tunnel
