NAS-WOL-handling by runeaudio

al.einstein

Hi there,

i´m using an selfmade NAS/Homeserver running Openmediavault 1.13 as storage for my music-collection and mounting the CIFS/SMB-Share in runeaudio workes nicely. The problem is: the NAS isn´t running all the time and must be WOLed by the client (which works perfectly with an Openelec-RPi2 and an i3-based Mediaportal-HTPC).

My first Question is: how can i make Runeaudio send a WOL-Packet prior to playback?
Weird thing happens when i choose a file from the playlist to be played while the NAS is still asleep.......playback starts (clock ticks up) but there´s no output, understandably.

My second Question is a little bit more complicated:

Same NAS is able to set itself to sleep-mode on various preconditions (i.e. checking for specific IP-adresses or monitoring the amount of data traffic). In my case the NAS checks if there are SMB/CIFS-Connections on Port 445. Server-Logs tell me that runeaudio doesn´t seem to close this connection after playback has stopped, so the NAS stays awake. Again: Openelec and Mediaportal work perfectly on that topic.

Is there a way to close the connection automatically - lets say - 5 mins after playback has stopped?

Cheers

Hi Al, here is some answers for you.

You have to follow this guide and install the proper software.
Than you have to hook the WOL command with the system. I suggest you to not hook with playback commands but hook it with system startup, it is an easier task. You can do that in an easy way by adding this line:

sysCmd('wol MACADDRESS');

at the beginning of the RuneAudio system worker (rune_SY_wrk), before this line should be fine.

You are right, RuneAudio is intended to handle network connections in a permanent way, so this behaviour is expected. But you can tweak the mount string acting on this line of code.

Hi and thanks for the answer,

hooking the wol-command to the system startup won´t work because - sorry not to mention that - i´m using an Raspberry Pi which basically runs all the time.

I´m not into Linux very much, so is there an option to "dismount" a network drive after a specific time?

Hi Al,
you can simply schedule a cronjob that execute the unmount command at a specific time.

You can create a script that stops MPD and unmount your mountpoint; for example you can call it umount-rune.sh and put into /root/ directory:

umount-rune.sh

#!/bin/bash
mpc stop
umount /mnt/MPD/NAS/<mountpoint name>

and then you need to schedule it by editing the system schedule /etc/crontab

# execute the umount-rune.sh script at 15:30 every day.
30 15 * * *       root      /root/umount-rune.sh

If CRON package isn't istalled, you have to install it using pacman

pacman -S cronie

You can use the same approach to auto-mount your NAS mount point at a specific time.

Ciao.

Hi Orion,

okay, the NAS could be unmounted at a specific time with "cron"......but can it be unmounted just after playback has been stopped?

To clarify things: choosing a song/album/playlist etc. for playback wakes the NAS via WOL and starts playing the music normally. When Playback has ended the NAS should automatically be unmounted and the connection via SMB/CIFS be dropped.

Fundamental Question: would it be easier on that topic to use NFS or DLNA?

Cheers

EDIT: I dicovered another very unpleasing behavior of my RPi running Runeaudio: if another client wakes my NAS runeaudio connects automatically an therefore keeps it awake even if there is no playback from RPi at all.........
