Hi,

Many thanks for your report. Are you using any other web server? I guess mympd is started by a service and it is not needed to run the command in CLI.

Hi Michalng, thank you for your support.

I installed a fresh dietpi image, additional software: pihole, shairport-sync and mympd. i use mympd in my browser (ip-adress:1333). because i could not access mympd i was trying 'mympd' in the terminal. this is where i found the warning and error message:

Joulinar is right that myMPD is started as system service. Starting it manually from the command line uses an unintended user and unintended options due to missing command arguments, like port 80 which is used by a regular webserver.

To start/stop/restart myMPD, do it via its systemd service, like:

systemctl restart mympd

If you cannot access, debug it via:

journalctl -u mympd

[Joulinar]

as well you can check LISTEN ports to check if myMPD is running on correct port

ss -tulpn | grep LISTEN

[sofad]

this is what i did:

systemctl restart mympd

ss -tulpn | grep LISTEN

--> mympd is not running / listening

[Joulinar]

looks like config option for web server port is incorrect. That's why mympd is trying to start with port 80, which of course is failing as port 80 is already used by the web server serving PiHole.

Unkown config option: webserver - webport

let me have a look

[Joulinar]

ok found it, the web server port option changed. You would need to adjust /etc/mympd.conf

remove webport = 1333 and adjust httpport = 80 to httpport = 1333

Once done restart service systemctl restart mympd.service

[MichaIng]

Many thanks guys! Fix has been merged. I'll also add a MOTD hack fix, as it's a trivial string replace here 😉.

Quick fix:

sed -i "s/'webport/'httpport/g" /boot/dietpi/dietpi-software

[MichaIng]

Also, we need to disable the option on Debian Stretch, since myMPD now requires MPD v0.20.0 at least, while Stretch ships v0.19.21:

• https://github.com/jcorporation/myMPD/releases/tag/v7.0.0
• https://packages.debian.org/stretch/mpd

... ah no wait, we ship own v0.20.23 packages for Stretch 👍: https://dietpi.com/downloads/binaries/all/

Thank you very much!
