Help with Jail rc.d script not executing on startup

[FrankWard]

I've created a Jail with the Subsonic streamer. I've set up the script as /etc/rc.d/subsonic and set permissions with chmod 777 and chmod +x. I've added the enable command in rc.conf. When I run "/etc/rc.d/subsonic start" from the CLI it works and the web UI is accessible. However, it doe not execute the script when the jail is rebooted. Here are my scripts. Is there anything I'm missing?

/etc/rc.conf

Code:

subsonic_enable="YES"

/etc/rc.d/subsonic

Code:

#!/bin/sh

. /etc/rc.subr

name="subsonic"
rcvar="subsonic_enable"

start_cmd="${name}_start"
stop_cmd=":"

load_rc_config $name

subsonic_start()
{
echo "Running Subsonic"
/var/subsonic/subsonic.sh
}
run_rc_command "$1"

Thanks!

Installing the subsonic-standalone port or binary pkg should place the appropriate service file under:
/usr/local/etc/rc.d/

Why did you create one from scratch?

* Not available as a binary pkg

I did some research before installing and came across this thread which says the plugin was not available. I did more research and saw much of the same about Subsonic not being available, so I followed the steps taken to install it manually. Please point me to the plugin version if you know where I can find it. Also, I didn't see any default service file created using the Subsonic Stand-Alone Installation.

I've been running Subsonic for years and have a lifetime license, so I wanted to port my old data into it along with the license which worked fine with my current setup. I just can't get the RC to launch the default subsonic.sh script created by the installer.

I can adopt a different solution such as crontab, etc., but I'd like to also know why this approach using RC doesn't work. If anyone can tell me what I might be doing wrong with the RC approach I'd appreciate it.

FreeBSD package != TrueNAS plugin. But apparently subsonic is not available as a package. You could still install from ports, though:

FreshPorts -- www/subsonic-standalone: Subsonic streaming media server, standalone version

Subsonic instantly transports your media to any HTTP connected device regardless of bitrate. You can stream to multiple players simultaneously. Subsonic is designed to handle very large music collections. By using transcoder plug-ins, Subsonic supports on-the-fly conversion and streaming of...

www.freshports.org

Now to debug problems with startup scripts you can place these two lines in your rc script after the #!/bin/sh:

Code:

set -x
exec >/tmp/subsonic.log 2>&1

Then restart your jail and check that logfile.

It's available in the Ports Collection, under www/subsonic-standalone

I kid you not: I thought to myself "I bet Patrick just jumped in here with more useful information than I can provide. I hope he has!"

Thanks, mate

Hey I learned something new from this thread, which I wasn't familiar with before (being a FreeBSD newbie): software with a "restricted" license is not made available as a binary pkg.

(I'm not sure why, as it probably gets into the weeds of licensing, legality, and FreeBSD philosophy and packaging rules.)

 

[Patrick M. Hausen]

If the copyright holder of that piece of software explicitly forbids distribution in binary form, that is that. About their motivation one can only speculate.

Thank you for the info!

First, if I set it up in crontab with (@Reboot sh /var/subsonic/subsonic.sh) it works fine. So, this is just my curiosity to understand how jails work a bit better.

The log shows that the RC script is working and starting Subsonic, but the process is not running, so I check another log and see (/var/subsonic/subsonic.sh: java: not found). I updated the script to the correct location of Java and it's now loading.

Can anyone explain why the Jail can't see Java in the path but the shell and crontab can?

During the startup phase /usr/local/bin is not in the search path. It's good practice to call everything with full absolute paths in rc scripts, anyway.
Glad I could help.

Jails as commonly used in TrueNAS are a full virtual FreeBSD installation. That's why I am sometimes frustrated with users complaining about the lack of plugins or docs etc. It's a lightweight "virtual machine". The FreeBSD handbook applies. Case closed in my opinion.

Q: "But how do I install guacamole?"
A: Create jail, enable SSH in jail, start jail, pkg install guacamole-server; pkg install guacamole-client

That's it. Plain FreeBSD. I'm simplifying a bit, of course, but essentially there is no magic involved. Jails are brilliant.

Agreed. Thanks again.
