After some brief testing of latest -master, noticed that e.g. mpd (musicpd)
listens on *:6600 (got that info from sockstat(1)), but I could connect to
that port on only one IP. localhost (::1 or 127.0.0.1) did not work, but one
probably not much help w/r/t 2.6 - but I was able to use gmpc
to toggle back btw 10.x & 127.0.0.1 on my workstation
(in case this wasn't tested elsewhere)
