Problem in running Nagios NRPE

[vincenthui]

Hi,

I installed NRPE v2.12 to monitoring my Scalix Email Server, however, I cannot run the check_nrpe command which included sudo command such as check_services.py. The error "NRPE: Unable to read output" shown.

I already visudo nagios for the script folder. I have tested to run sudo /check_services at command line without problem only cannot run on check_nrpe.

Thanks,
Vincent

Be sure your /etc/sudoers file contains this:
#Defaults requiretty
