Cenzor wirtualnego świata
Problem jako taki udało mi się rozwiązać ale może komuś się przyda.
Zainstalowałem mpd oraz dwa klienty -- gmpc i sonata . W obu przypadkach nie szło się podłączyć do mpd. Config /etc/mpd.conf był domyślny. Znalazłem wątek sprzed 5 lat -- http://forum.dug.net.pl/viewtopic.php?id=12005 i po przejrzeniu go ustaliłem co nasŧepuje:
W pliku /etc/mpd.conf widnieją wpisy:
bind_to_address "localhost" port "6600"
lsof zwraca:

A mimo to, przy odpaleniu gmpc dostałem komunikat:

W sonacie z kolei dostałem coś takiego:
morfik:~$ sonata

...Po wyexportowaniu:
export MPD_HOST=127.0.0.1 export MPD_PORT=6600
Sonata się łączy ale gmpc dalej pluje błędami.
Okazał się winny adres ip. W gmpc były dwa profile jeden Music Player i drugi Default. Ja wybrałem ten pierwszy chyba nie muszę pisać dlaczego. Tam w polu komputer jest fe80::3e4a:92ff:fe00:4c5b . W default było zaś, nie pamiętam już co. xD W każdym razie w tym pięcioletnim wątku ludzie mieli się upewnić, że używają localhost, to wpisałem localhost. Dostałem poniższy błąd
Jun 23 11:03 : client: libwrap refused connection (libwrap=mpd) from [::1]:34955 Jun 23 11:03 : client: libwrap refused connection (libwrap=mpd) from [::1]:34958 Jun 23 11:03 : client: libwrap refused connection (libwrap=mpd) from [::1]:34960 Jun 23 11:03 : client: libwrap refused connection (libwrap=mpd) from [::1]:34962 Jun 23 11:03 : client: libwrap refused connection (libwrap=mpd) from [::1]:34964 Jun 23 11:03 : client: libwrap refused connection (libwrap=mpd) from [::1]:34965
To zmieniłem na 127.0.0.1 i problem się rozwiązał. Co ciekawe, to przy fe80::3e4a:92ff:fe00:4c5b w iptables można było zaobserwować przypisanie zapytań do regułki z
12 2475 REJECT udp -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
Ale wyłączenie zapory nic nie zmieniło.
Przy okazji znalazłem trochę nieaktualny poradnik od mpd http://jakilinux.org/aplikacje/uzywaj-mpd-i-ncmpcpp … fesjonalista/ . Z niego się dowiedziałem, że można mpd startować per user i całą konfigurację trzymać w katalogu /home/morfik/ . Wystarczy skopiować zawartość /etc/mpd.conf i wrzucić ją do ~/.mpdconf oraz stworzyć katalog ~/.mpd/ a w nim odpowiednie pliki:
mkdir -p ~/.mpd/playlists touch ~/.mpd/mpd.db touch ~/.mpd/log
mpd będzie działać lokalnie przy odpowiednim dostosowaniu ~/.mpdconf (jeszcze się temu nie przyglądałem zbytnio) oraz wydawaniu polecenia mpd jako zwykły user. Poza tym, przy używaniu mpd > alsa> pulse dźwięk jest bardzo zniekształcony ale przy bezpośrednim przesyłaniu do pulse już jest wszystko w porzadku.
Póki co, trzeba ubijać i gmpc/sonatę + mpd by zatrzymać dźwięk. W przypadku ubicia samego klienta, dźwięk jest dalej odtwarzany. W przypadku gdy chce się konfigurować mpd per user, trzeba wyłączyć domyślnego demona w pliku /etc/default/mpd :
START_MPD=false
W przeciwnym wypadku dostaniemy błąd:
[....] Starting Music Player Daemon: mpdFailed to bind to '[::1]:6600': Address already in use no message buffer overruns failed!
Obra programy zjadają razem 50MiB:
# ps -eo "%mem user args" --sort -%mem | grep mpd 0.8 morfik mpd # ps -eo "%mem user args" --sort -%mem | grep gmpc 1.7 morfik gmpc
Także, wszystko jest na najlepszej drodze by amaroka się pozbyć o ile tylko uda mi się dostosować klienta.

Na kilku komputerach już instalowałem i nie ma żadnych problemów.

Generalnie nie trzeba exportować:
export MPD_HOST=127.0.0.1 export MPD_PORT=6600
Samo zmienienie adresu z localhost na 127.0.0.1 pomaga, praktycznie w każdym kliencie. Trochę lipa z tymi textowymi klientami tam ciągle trzeba wpisywać --host 127.0.0.1 --port 6600. xD
No i dobrze, że jest możliwość update bazy, bo jak tagi zmieniłem to nie mogłem ich uaktualnić, a tak można to zrobić przez:
mpc --host 127.0.0.1 --port 6600 update

Te wszystkie textowe klienty chcą tego, nie mogli w nich zdefiniować domyślnych opcji? W sumie to już lepiej jest wyexportować te zmienne i mieć święty spokój. xD
Przecież te problemy występują tylko u ciebie :)
Ustaw wszystko raz dobrze i nic więcej nie będzie trzeba dopisywać.
