I'm running a probe with no arguments with NRPE v4.0.3 on a RHEL7.9 remote server.
I keep getting error:
NRPE: Unable to read output
When I run:
sudo journalctl -u nrpe --since "1 hour ago"
on the remote server,
I always get the same error:
WARNING: my_system() seteuid(0): Operation not permitted
I parsed a few topics regarding that last error, but none seems to address my issue.
Here is the most valuable insight on this issue:
On more than a dozen other RHEL servers (6.9, 6.10, 7.9) with the same NRPE version, the same code executed with NRPE works perfectly.
I keep trying to figure out which configuration box I didn't ticked, because the error clearly doesn't seem to come out of the code.
Could you please review my issue?
