Wait, I have just realized that in order to let mpd.service open both IPv4 and IPv6 ports I *need* net.ipv6.bindv6only = 1 (I have settted it now from /etc/ sysctl.d/bindv6only.conf)
I also observe that mpd.socket will not open the IPv4 port no matter the value of net.ipv6.bindv6only. Now I'm even more confused. -- 1: Una computadora sirve: * Para tratar de dominar el mundo, un caso conocido de esto fue el de Skinet Damian Nadales http://mx.grulic.org.ar/lurker/message/20080307.141449.a70fb2fc.es.html Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
