unable to bind UNIX socket to /var/run/bitlbee.sock

[fuze]

Hello,

I am using Bitlbee version 1.2-3 on a Ubuntu 8.04 server setup. Bitlbee worked fine until yesterday when there was a power interruption at my house and the server fell out. After rebooting I find this error in my /var/log/daemon.log when I start bitlbee using "sudo /etc/init.d/bitlbee start":

bitlbee[4932]: Unable to bind UNIX socket to /var/run/bitlbee.sock: Permission denied

I am running the default configuration (which worked up until the power interruption yesterday). I've tried restarting the server properly and reinstalling bitlbee via repositories, but no help. The user & group bitlbee are present on the system.

[fuze]

I changed permissions on /var/run to 777 and after that the bitlbee.sock was made while starting bitlbee. However, I can't connect using 'irssi -c localhost' like I used to do before.

I'm guessing something was corrupted by the power interruption just shutting down the server instantly. Don't know how to solve this or where to start looking though.

This message should be a red herring, /var/run/bitlbee.sock isn't essential for anything.

Is the BitlBee process running at all? Does lsof show it listening on a TCP socket?

[fuze]

snipped output of 'lsof | grep bitlbee':

bitlbee 6341 bitlbee 0u unix 0xcb96d400 16184 socket bitlbee 6341 bitlbee 1u unix 0xc904aa00 16185 socket bitlbee 6341 bitlbee 2r REG 8,1 33563 854039 /usr/share/bitlbee/help.txt bitlbee 6341 bitlbee 3u 0000 0,6 0 529 /anon_inode:[eventpoll] bitlbee 6341 bitlbee 4u unix 0xcb96d200 16180 socket bitlbee 6341 bitlbee 5u unix 0xcb96da00 16181 socket bitlbee 6341 bitlbee 6u IPv4 16183 TCP *:ircd (LISTEN)

So yes, it is listening I guess?

Sorry for the formatting.

Definitely looks like it is, yes. On all addresses, not just localhost.
And you get connection refused when connecting to localhost:6667?

[fuze]

It keeps hanging here:

16:04 -!- Irssi: Looking up localhost
16:04 -!- Irssi: Connecting to localhost [127.0.0.1] port 6667

Whereas yesterday it would just connect within the second.

[Wilmer van der Gaast <wilmer@…>]

What happens when you type "telnet localhost 6667"?

[fuze]

The same thing, nothing happens..

[Wilmer van der Gaast <wilmer@…>]

Odd. When you try to restart BitlBee, does it really restart? Can you use strace to see what the process is currently doing?

[fuze]

strace on the pid gives this (while trying to connect to it with irssi):

Process 6533 attached - interrupt to quit
clock_gettime(CLOCK_MONOTONIC, {20132, 807382782}) = 0
epoll_wait(3,

Restarting bitlbee gives a new pid so I guess it is restarted properly?

[wilmer]

Yeah, that sounds like a successful restart.

Looks like my last comment got lost: When you connect, do you see any activity in the strace output at all?

[wilmer]

BTW, with nothing happens, do you mean that you don't get any connection, or that the connection is silent? As-in do you see this:

tewilmer@veer:~$ telnet localhost 6667 Trying ::1... Connected to localhost. Escape character is '^]'.

Or nothing after "Trying"?

[fuze]

I see nothing after trying. Also in the strace nothing pops up while I try to connect.

[Wilmer van der Gaast <wilmer@…>]

It's starting to sound more like a firewall issue... BitlBee is listening on localhost, and even "telnet localhost 6667" doesn't get a connection. Can you check your firewall (ufw?) rules?

[wilmer]

I guess it was indeed the firewall?
