Check_radius return Auth error when runned from cron job

[pa4rm]

I’ve configured one service for radius check. Cron job execute this check within “/opt/librenms/services-wrapper.py 1”.

When “/opt/librenms/services-wrapper.py 1” runs from cron job, check_radius service will return Auth Error. However if I start “/opt/librenms/services-wrapper.py 1” manually, check_radius service return Auth OK.

Anyone an idea what can be reason for this issue?

Are you running the services-wrapper.py script as the same user as your cron? Should be librenms user.

You are right @laf. Manually I run the wrapper as a root. After a troubleshooting I found that my “/etc/radiusclient/server” has not appropriate file permissions to be read by “librenms” user. After correcting permissions everything works fine.
Thank you very much
