Generic Agent cmd execution [Solved]

[ronil21]

Hi,

I'm tring to run custom scripts by generic agents jobs on OTRS 6.0.26 in a CentOS system. However is not working.
I've tried to disable firewall and selinux. I've already have checked the permissions on my script and the script file log. Both has the otrs user as owner and makes part of apache group.

The interesting thing of this is that I am able to run the same script on the OTRS in a Ubuntu system. I just have problem on CentOS.

Somebody can share some tip to help me to solve this?


Thanks.

Hi,

Let's start by showing us your GenericAgent configuration.

Hi,

Is it the same command as under the other OS? I never tried two arguments, I would chmod+x the script and just put /opt/otrs/bin/ping.sh in.
Did you tested the script by executing it with the OTRS user?

- Roy

[ronil21]

Yes, is the same command in both systems.
No, I didn't test the script using the otrs user by cli. I will try now and also try execute the command without the "/bin/sh" arguments.

Soon I will update this forum.


Thank you.

Interesting, with the OTRS user by cli is not working the script is not running. I will check that. But do you have some tip? Because the script theoretically already have the necessary permissions.

5658149 0 -rw-r--r-- 1 otrs apache 0 Fev 26 12:30 testeping.log


Thanks

Hi,

Is there any error during execution? I suggest to fix your script first until you run it through the GenericAgent

[ronil21]

There is no error on execution. However I've change now the directory where my script was. Now it is on "/opt/otrs" and now by cli with the OTRS user the script runs, but still is not working from the GenericAgent.

[root@srv-otrs otrs]# su - otrs -c '/opt/otrs/ping.sh'
[root@srv-otrs otrs]# cat ping.sh
#!/bin/sh

ping -c 3 www.google.com.br >> testeping.log
[root@srv-otrs otrs]# pwd
/opt/otrs

Hi


Set the SysConfig MinimumDebugLevel to debug execute the GA and check otrs and web server log.

Hey,

You're most likely just having a permission problem.

Code: Select all

touch /opt/otrs/testeping.log
/opt/otrs/portal/bin/otrs.SetPermissions.pl

CMD: /opt/otrs/ping.sh and get sure that the Generic Agent is having a match =).
The apache log, as told already, will tell you if there are any problems.

Best regards
Emin

Edit: Get sure to use an absolute and not a relative path in your script.

[ronil21]

Roy,

Was a permission problem in the log file of the script. I could solve changing the path to the file

[root@srv-otrs otrs]# tail -f /var/log/httpd/error_log
Module: ModPerl::RegistryCooker::default_handler (v1.99) Line: 173
Module: ModPerl::Registry::handler (v1.99) Line: 32

/opt/otrs/ping.sh: line 3: testeping.log: Permission denied
/opt/otrs/ping.sh: line 3: testeping.log: Permission denied
/opt/otrs/ping.sh: line 3: testeping.log: Permission denied
/opt/otrs/ping.sh: line 3: testeping.log: Permission denied
/opt/otrs/ping.sh: line 3: testeping.log: Permission denied
/opt/otrs/ping.sh: line 3: testeping.log: Permission denied
/opt/otrs/ping.sh: line 3: testeping.log: Permission denied


Before was:
[root@srv-otrs otrs]# cat ping.sh
#!/bin/sh

ping -c 3 www.google.com.br >> testeping.log

And now is:
[root@srv-otrs otrs]# cat ping.sh
#!/bin/sh

ping -c 3 www.google.com.br >> /opt/otrs/testeping.log


Thank you very much for you help

[ronil21]

Was exactly this.

Thank you all.

Hi,

First of all: please don't hijack old threads. Second: are you sure you know what you're doing there? You start an OTRS GenericAgent module with the bash?
