mpd fails to bind to 6600

I am trying to run mpd with a systemd user script.

When I run the service it fails with the following:

Nothing at all is running on port 6600. I am sure of this.

lsof -i :6600

returns nothing.

Re: mpd fails to bind to 6600

Run that lsof as root.

In any case there are two separate issues and mpd fails due to misconfiguration in the config file, so you might want to check/post that.

(And don't use the -x option when posting a journal to the boards, it's jarring to read and largely useless fluff)

Re: mpd fails to bind to 6600

I ran lsof as root. Nothing.

here's my mpd .conf

# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This 
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory		"/mnt/sparrow/media/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use 
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory		"/mnt/sparrow/media/music/.mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the 
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file			"~/.mpd/database"
# 
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog.
#
log_file			"~/.mpd/log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file			"~/.mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server 
# state will be reset on server start up.

#
# This setting specifies the group that MPD will run as. If not specified

# This setting sets the address for the daemon to listen on. Careful attention

# Audio Output ################################################################

Re: mpd fails to bind to 6600

I should note. When I run this as a root systemd service, it binds to port 6600.

Re: mpd fails to bind to 6600

Is the port maybe in a TIME-WAIT status? https://vincent.bernat.ch/en/blog/2014- … tate-linux

ss -tepan '( sport = 6600 )'

Re: mpd fails to bind to 6600

sorry. the issue was in my config.
