I've tried using both os.system as well as subprocess.call to invoke an external command that is not working for me. It has something to do with the command I am trying to run, which is squeezy, a command line interface for logitech media center. I've been able to use os.system as well as subprocess.call successfully in an agi using other commands, but not squeezy. I can get squeezy to work using both os.system as well as subprocess.call in an external python script if I copy out the revelant chunk of code, but it will not work in an agi. It works in an external python script if I run it as either root or asterisk, so I don't think it is a permissions issue... If I try to run squeezy in the agi using subprocess.call or subprocess.check_call, the python agi dies right there if I use os.system, the command still doesn't run as expected, but the agi continues normally. I don't know how to capture any useful output since the agi dies if I try to use subprocess.check_call. I don't see any of the regular python error messages in my asterisk CLI output, the only output I see I generate myself with agi.verbose How can I get to what is happening in the agi? Can the python errors/output be redirected somewhere I can see them? I have been debugging my issues using external python scripts to test, but in this case my issue goes away in the external script... I would appreciate any advice :) thank you very much to all for the wonderful piece of software, it is so nice to be able to use python for agi scripts! |

ok, I redirected stderr to a file, here it is:

Try passing the full path for ‘squeezy’.

thanks Daniel, that did the trick
I guess /usr/local/bin/ is not in the path used by agi's.... seems so odd
though that it would work if I ran it outside of an agi as the asterisk
user, I would think the paths would be the same since both run as the
asterisk user...
anyway, it works now, which is what's most important to me :)
thanks again!
