Till now I was successfully running Nagios 2 on FreeBSD but I have to move to linux. I was able to compile and install but I have a problem starting it. When I did:
I got this message:
Warning: Could not set effective GID=502
Warning: Unable to change supplementary groups using initgroups() – I hope you know what you’re doing
Warning: Could not set effective UID=503
Nagios 2.0b2 starting… (PID=28934)
Do you know what that is and what to do with it as I’m new to linux?
