Failed to bind to '127.0.0.1:6600': Address already in use

Question

I'm using ubuntu 12.10 for my MPI(message passing interface) configuration I have installed mpd after installation I have start mpd, it is started normally no error message display but when I'm trying to run the command "mpd &" it gives me error message "Failed to bind to '127.0.0.1:6600': Address already in use" I have tried many solutions but the result is same.

root@ub0:~# service mpd start

Starting Music Player Daemon mpd
[ OK ] root@ub0:~# service mpd restart

Stopping Music Player Daemon mpd
[ OK ] Starting Music Player Daemon mpd
[ OK ] root@ub0:~# mpd &

[1] 2881 root@ub0:~# Failed to bind to '127.0.0.1:6600': Address already in use

[1]+ Exit 1 mpd

Solution

You're getting the error because it's already running:

[ OK ] Starting Music Player Daemon mpd

You don't need to start it by hand (by doing mpd &), your init system is taking care of that.

Unless I'm misunderstanding something, you're trying to run the daemon twice. It should be pretty obvious why this fails; the first time it ran, it bound that address, and running it again fails to bind to it because the first instance is already bound.

Assuming this is TCP, and you know the port number (e.g. your 6600), use lsof -itcp:6600 -stcp:listen to find out what's running already on that port. More generic: lsof -i :6600 ...
