Da qualche mese il mio PC ha smesso di vedere alcune cartella condivise che avevo sul NAS QNAP TS-412.
PC e NAS sono sullo stesso gruppo di lavoro, son collegati in ethernet, il collegamento tramite FTP funziona e anche tramite SSH. Dovrei avere già attivato SMB e tutto.
Prima dal computer facendo \\NAS\Multimedia o con l'ip entrava chiedendomi i dati di login senza problemi. Ora invece, anche tramite il programma QNAP QFinder quando provo a collegare l'unità di rete o aprirlo in esplora risorse mi dice "Impossibile accedere al dispositivo e alla cartella condivisa. Verificare la connessione di rete, il nome utente e la password e che il dispositivo sia stato acceso."
Collegandomi in ssh e facendo smb2status mi risponde:
smbd (samba daemon) Version 4.4.16
smbd (samba daemon) is running.
max protocol SMB 3 enabled.
Ho provato anche dalla TV e pure da lì non mi vede più le cartelle.
Ho dato un occhio nella configurazione in /etc/config/uLinux.conf e ho trovato questo:

WARNING: socket options = TCP_NODELAY SO_KEEPALIVE SO_SNDBUF=65536 SO_RCVBUF=65536
This warning is printed because you set one of the
following options: SO_SNDBUF, SO_RCVBUF, SO_SNDLOWAT,
SO_RCVLOWAT
Modern server operating systems are tuned for
high network performance in the majority of situations;
when you set 'socket options' you are overriding those
settings.
Linux in particular has an auto-tuning mechanism for
buffer sizes (SO_SNDBUF, SO_RCVBUF) that will be
disabled if you specify a socket buffer size. This can
potentially cripple your TCP/IP stack.
Getting the 'socket options' correct can make a big
difference to your performance, but getting them wrong
can degrade it by just as much. As with any other low
level setting, if you must make changes to it, make
small changes and test the effect before making any
large changes.
