[SOLVED] mpd error: Failed to bind to '127.0.0.1:6600': Cannot assign requested address

273 · 05-28-2012, 07:03 PM

I installed mpd following the instructions here:
http://crunchbanglinux.org/forums/to...ate-mpd-guide/
Basically install using apt-get, stop and disable running it as a service and create the config and other files in home directory.
When attempting to start mpd for the first time I receive the following error and mpd fails to start:

Code:

Failed to bind to '127.0.0.1:6600': Cannot assign requested address

I saw mention somewhere that commenting out

Code:

bind_to_address                "localhost"

works for some but I just receive a different error:

Code:

listen: bind to '0.0.0.0:6600' failed: Address already in use (continuing anyway, because binding to '[::]:6600' succeeded)

This looks better but a the next step the following happens:

Code:

me@pc1:~$ mpc update
error: Timeout while connecting

When mpd is running I see the following:

Code:

root@pc1:~# netstat -a |grep 6600
tcp6       0      0 [::]:6600               [::]:*                  LISTEN

When it's not I see nothing when running that command.
I'm beginning to think there's something weird going on with my networking. Any ideas what could cause this?

It looks like something was already bound to the port for ipv4 but not ipv6 ... stop mpd and try:

Code:

netstat -tnlp | grep 6600

.. hopefully this will show the offending process.

Yes, that what I thought was going on. There doesn't seem to be anything using the port though:

Code:

root@pc1:/home/me# netstat -tnlp | grep 6600
root@pc1:/home/me#

OK, this is odd, I changed the following in the config file:

Code:

bind_to_address         "192.168.2.100" #LAN IP

Now when I run mpc locally specifying the local machine using it's hostname, localhost, loopback or LAN IP I get the timeout error, but accessing it from my netbook on the same LAN works.

This is too weird. I can control mpd from my netbook fine using mpc, ncmpcpp and an MPD screenlet when I tell mpd to listen on 192.168.2.100 but anything I start on the PC running mpd just times out...

Is iptables running ?

I don't see it in the output of lsmod. I am wondering if this is part of a bigger problem though because, for example, conky can no longer query hddtemp.

It turns out ifupdown was missing after an update, so re-installing it fixed this.

Slightly worrying ... better make sure nothing else is missing
