[Bug 174211] Re: SMBD hangs on startup if lo is down

[Steve Langasek]

Not related to upstream bug #4052.

port 631 is the ipp port.  I can't reproduce this problem here with the
current version of Samba, but it appears that your server is set up with
'load printers = yes' and is trying to read the list of available
printers from the local cups server.  Yes, if your system needs to
connect to localhost and can't find a route to it, this is the behavior
that will result.  I submit that this is a misconfiguration of your
network interfaces, not a bug in samba; if you had no network interfaces
enabled, then at least the connection attempt would have failed
immediately, but to have some network interfaces up without lo being one
of them is going to confuse a number of applications, not just samba.

As a workaround, you can either bring the lo interface up (as it should
be), or you should be able to stop samba from looking for cups on
startup by setting 'load printers = no' or 'printing = bsd'.  Either
way, I don't think it's the samba package is responsible for
compensating for misrouting of 127.0.0.1, so I'm marking this bug as
invalid.
