You are correct. Everything was running as nobody. For some reason when I let root read the gentuner file it started working.

My Linux box took a dump. I'm switching my server back to windows for now. Is there an externaltunerplugin type thing for windows? Something where I can run a script to change channels on my DirecTV boxes over the network?

That is exactly what I'm looking for, but it appears that it does not work with SageTV V9.

It does work. You just have to use a different registry key:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Frey Technologies\Common\EXEMultiTunerPlugin

I updated my gentuner script from the first page of this thread to support Genie mini clients. It works well with EXEMultitunerPlugin. I updated the code block on the first page, but I'll also leave a copy here in case anybody wants to use it.

tune.pl.txt
  • I installed strawberry perl on my windows box.
  • I made a batch file called tune_it.bat to call my perl script. This may not be needed, but I was troubleshooting the issue of having the wrong registry key and this works. The batch file simply contains: C:\Strawberry\perl\bin\perl.exe C:\TuneChannel\tune.pl TUNE %*
  • My registry key is:
    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Frey Technologies\Common\EXEMultiTunerPlugin
    command REG_SZ c:\TuneChannel\tune_it.bat %DEVICE% %CHANNEL%

I'm back to trying (and failing) to get gentuner working on a v9 Linux server. My source lists as a 'Generic Stub Device', and when I try to change the Tuning Device from the list, there are no devices that show up.

In the old 32-bit version of the tuner there was a remotes config file in which the devices were defined. Apparently gentuner does not recognize the config file. How are the sources enumerated such that they appear in the pick list? Is there specific syntax or location for these data?

The devices are defined in the gentuner script itself, which you have to customize for your own setup depending on how you are tuning. I don't remember seeing a gentuner example that reads from the remotes file, although of course someone could have created one. The docs are here: https://github.com/jwittkoski/Generi...ster/README.md and there are some example gentuner files in that repo as well.

Can you describe what types of tuners you are using?

You can test gentuner by running the gentuner script directly. I recommend testing it this way before trying to configure anything from within Sage.

For example:

Code:
$ cd /opt/sagetv/server/
$ ./gentuner REMOTES
FiOS-TV-1
FiOS-TV-2
FiOS-TV-3
$ ./gentuner TUNE FiOS-TV-1 504
$
--John

$
--John
Here is my confusion on these examples:
  • I understand that "gentuner" is the tuning script; which HAS to be named "gentuner"
  • I don't know what 'REMOTES' means in this context; is it an argument of the gentuner command?
  • I assume the 'FIOS-TV-#' are devices, but are there supposed to be files with corresponding names?
  • What is the 'TUNE' term? Is it a command, an argument, a filename? is it required?
My script just passes two arguments (channel number, tuning device) to a simple wget command. In the old (32-bit) tuning command it read the Tuning Devices list from a separate configuration file, but once those were defined all of the commands were controlled by the script.

I'm just having trouble trying to understand the structure and requirements of this version of the tuner ...

Edit: I also should have mentioned that when I tried to run the gentuner from a command line I get a 'permission denied' warning.

I'd recommend that you read the README the jpwegas linked to, since, I think it covers all your questions, and, it's there to help understand the requirements of gentuner.

I'd also look at some of the example scripts, like this one...
https://github.com/jwittkoski/Generi...gentuner.IPSTB

since they pretty show how it all works (but read the README first).

On unix systems, scripts will need the execute bit set in order to be run.

chmod +x gentuner

I've seen the README file(s) and examples, but the issues I mentioned are not addressed in those documents.

I have the gentuner script set as executable; it's was executable in its prior incarnation in v7 32-bit. I can run it from a command line (albeit only preceded by 'sudo') and it executes the channel change. The issue I have is in getting a list of Tuning Devices into the Sage sources setup dialog. I am stuck at a "Generic Stub Device", with no other Tuning Device options ...

To summarize the README for your questions:
  • If gentuner gets a REMOTES argument, it should return the names of the "remotes" you want to expose.
  • The device names are specified in gentuner itself. There is no need to read anything from a file (unless you want to modify your customer gentuner to do that, which seems overkill).
  • If gentuner gets a TUNE argument, it should tune the channel specified using the remote name specified.

The gentuner.IPSTB is a very simple example of a working script for a single remote. It only needs to do 3 things:
  • Return "OK" when it sees the "CAN_TUNE" argument
  • Return a list of remotes when it sees the "REMOTE" argument
  • Tune the channel when it sees the "TUNE" argument

To test your script:
  • When you run "./gentuner CAN_TUNE" it should print "OK".
  • When you run "./gentuner REMOTES" it should list your remotes(s).
  • When you run "./gentuner TUNE STB1 504" it should tune device STB1 to channel 504 (assuming in this example you have changed gentuner so that your remote is named "STB1")

From your description, it sounds like those commands work as expected, so the fact that you have to run it using 'sudo' makes me suspect that your problem is the user that is running the SageTV process cannot run the gentuner script.

Who is Sage running as? What are the permissions for the gentuner script? Can you post the gentuner script you are using?

Just to be clear, SageTV uses the output of "./gentuner REMOTES" to populate the tuning devices within Sage. If it can't run the gentuner script it will not be able to create the list. That's why I suspect it is a permission issue.

How are the device names specified in gentuner? Is there a "REMOTES" clause or identifier? The posted examples don't show lists of defined Tuner Devices. The "./gentuner REMOTES" command does not return anything, because the Tuning Devices are not defined anywhere. That is my major issue. The script is really simple, just two (SageTV-defined) arguments of Tuning Device and Channel. If I enter "[sudo]./gentuner DSS6 340" it tunes channel 340 on the device I have defined in the script as the active Tuning Device.

The problem is my not knowing how to populate the Tuning Device options within Sage ...

You must modify the gentuner script to return the names you want to appear in SageTV. They can be whatever you want.

For example, in gentuner.IPSTB, it's this line:

https://github.com/jwittkoski/Generi...uner.IPSTB#L23

SageTV uses the output of "./gentuner REMOTES" to populate the tuning devices within Sage.

Can you post your version of gentuner?

Near as I can tell, the Sage server is running as "user #2000". I have no idea what that means. The gentuner script is running as "root".

This is running under Ubuntu 18.04, so I don't know how or why these permissions were set, or what they should be. I may just have to scrub this Sage install and start from scratch ...

The owner of the gentuner executable on disk doesn't have to be the same as the one running it. When SageTV runs it, it will run as the user that SageTV is running as.

To check on the user the SageTV process is running as, you can:

Code:
ps -ef | grep -v grep | grep sage.Sage | cut -d" " -f1
In my case the user is 'sagetv', but it may be something different on your box.

To test the gentuner script as the user that SageTV runs as, run this, replacing USER with the user SageTV is running as from the above command:
Code:
su - USER -c "/opt/sagetv/server/gentuner REMOTES"
Can you post the output of the above command and also post the output of:
Code:
ls -la /opt/sagetv/server/gentuner

If it’s not running as the same user who owns the file, it needs to have execute permissions for all users:

chmod a+x gentuner
