[Pkg-mpd-maintainers] Bug#813754: Bug#813754: Bug#813754: Can't open port 6600 when run syste, -wide vis systemd

[Matthew E. J. Draisey]

I just fixed a situation where I couldn't get mpd to work over my home network.
I think it may be this same issue.

On my system

    # sysctl net/ipv6/bindv6only
    net.ipv6.bindv6only = 1

netstat would show init listening on [::]:6600 but doesn't report the
IPV6_V6ONLY socket state so I had missed there was no socket listening on ipv4.

Adding

    [Socket]
    BindIPv6Only=both

to the mpd.socket unit fixed my problem.
