Problem after each reboot

Hi,

After each reboot, I get a "The server is not accessible. Please try again later" error. I'm running Ubuntu Server 12.04, Serviio 1.0.1 and ffmpeg built from the source on the serviio download page.

I'm even running the serviio process using "root" to make sure it has all the required rights.

Here's the detail log:

check the permissions of the folders and files. Make sure they are set correctly. Also set the permission of the /tmp/Serviio/ directory

Here's the permissions:

The temp transcoding folder for serviio is /tmp/Serviio
The movie I'm trying to play is /home/media/video/movie.mkv


/tmp

  Code:

drwxrwxrwx   8 root root  4096 Sep 16 14:09 tmp

Since the serviio service is autostarted when the server boots using "root" I though it would have all the autorities it needs...

[npuser]

Try deleting 'serviio' folder inside /tmp [Default temp transcoding folder] and let the process auto created it using the proper permission. Or use -DdefaultTranscodeFolder=/home/somefolder/temp system variable to override the default tmp tc location.

NPuser

I've deleted the "Serviio" folder inside /tmp and rebooted. Tried streaming again to the TV and got the same server not accessible error...

The "Serviio" folder has been automaticaly recreated though:

  Code:

drwxr-xr-x 2 root     root     4096 Sep 17 17:53 Serviio

What else can I try?

I tried a couple of things and I found out that when I do

sudo service serviio stop
sudo service serviio start

Everything works! But when I reboot I get the same error again. So it seems that after a reboot, the serviio service is started automatically (without me doing a sudo start) but it's missing rights.

Here's the complete steps I took to install serviio:

cd /opt
sudo wget http://download.serviio.org/releases/se ... nux.tar.gz
sudo tar -zxvf serviio-1.0.1-linux.tar.gz
sudo mv serviio-1.0.1 serviio
sudo rm -f serviio-1.0.1-linux.tar.gz

sudo ln -s /opt/serviio/bin/serviio.sh /usr/bin/serviio

sudo useradd -d /opt/serviio -r serviio
sudo usermod -a -G root serviio
sudo chown -R serviio:serviio /opt/serviio

sudo nano /etc/default/serviio

sudo update-rc.d serviio defaults



What is wrong with this setup that makes the automatically started service after a reboot missing rights?
(As I said, I even tried running the service as root in the deamon script configuration with the same results.)

Thanks.

Anyone got an idea why I can't autostart the service correctly (with "serviio" or "root" user).

I always have to do
sudo service serviio stop
sudo service serviio start

for serviio to work

I had the same problem with Ubuntu 12.04, but have fixed it.

NB "service start ..." and "service stop ..." are *so* ubuntu < 12.x

I suspect that's where the problem lies, specifically with the upstart script. When the system starts it will start services in the newer "start ..." upstart manner, and this doesn't work for Serviio with the script I had previously.

I just rewrote my upstart script, and the start/stop commands now work. Serviio now starts up with the system perfectly.

  Code:

root@Tobermory:~# cat /etc/init/serviio.conf
# Serviio - media server
#
# Serviio is a free media server. It allows you to stream your media files
# (music, video or images) to renderer devices (e.g. a TV set, Bluray player,
# games console or mobile phone) on your connected home network.

start on        started networking

script
        exec /usr/local/bin/serviio/bin/serviio.sh
end script



Thanks

Yes, that did it! Thanks a lot.

This method starts the deamon as root, is it ok to do that?
Is there a way to start it using the "serviio" user?

Depending on how open your system is to the outside world or people who are not you.

I will look at changing user later. I know it can be done.

Try this:

  Code:

# Serviio - media server
#
# Serviio is a free media server. It allows you to stream your media files
# (music, video or images) to renderer devices (e.g. a TV set, Bluray player,
# games console or mobile phone) on your connected home network.

start on        started networking

setuid <user>
setgid <group>

script
        exec /usr/local/bin/serviio/bin/serviio.sh
end script

change <user> and <group> to the name and group you desire.

That should do it.
