mpd and ncmpcpp

well I installed ncmpcpp, but when ever I try to run it I get this:

Cannot connect to mpd: problems connecting to "localhost" on port 6600: Connection refused

I have no clue what mpd was/is, so I installed it.. and ran "mpd"

unable to bind port 6600: Address already in use
maybe MPD is still running?

I am not familiar with mpd so I dont know what to do... I tried searching around but didnt find anything that solved my problem. Thankshave

Re: mpd and ncmpcpp

Hmm, could you paste your .mpdconf here?

Re: mpd and ncmpcpp

Ok. Do you by any chance start mpd at boot or as a daemon (/etc/rc.d/mpd start)?
Because in that case, as normal user you have no permissions to play music. You can fix this by either specifying a user in the conf file (look under "daemon options") or just run mpd as a normal user from CLI.

Re: mpd and ncmpcpp

You better just start mpd as a user. Much less hassle.
And be sure you have write permissions for /var/lib/mpd/

Re: mpd and ncmpcpp

I use mpd as a daemon on my laptop and it works just fine.  You just have to make sure you change this line:

user                            "mpd"

And replace "mpd" with your user in quotes.

Re: mpd and ncmpcpp

ncmpcpp? Good choice On the first run, I also had some problems getting mpd to work, but the hints given above are exactly those, which I had wrong, so I'm sure you'll get it to work.

Re: mpd and ncmpcpp

Alright. As for the folders you have specified, you have to make sure they exist. Also, I would recommend, at least for testing purposes, to run mpd as normal user via command line (just running "mpd"), so you will be able to see some debugging output.

Re: mpd and ncmpcpp

[k0rfain@core ~]$ mpd
unable to bind port 6600: Address already in use
maybe MPD is still running?

and im sure all of the folders are there(just checked, will re-check later)... Im not sure what the problem is. why so much work to get an audio player to work anyway

Re: mpd and ncmpcpp

Did you check whether mpd is actually running?

ps aux | grep mpd

Re: mpd and ncmpcpp

What is the output of the following?

ls -l /var/lib/mpd /var/log/mpd /var/run/mpd

Re: mpd and ncmpcpp

Those are the wrong permissions.. make sure you go through the ArchWiki :: Mpd - Quick Single User Installation section.

Re: mpd and ncmpcpp

Also, you need to kill mpd before you run it as a user, so:

killall -9 mpd; mpd

You might need to run the first command as root, or with sudo.
