I'm having a strange issue with the check_dhcp plugin v1.4.16 on SL6.
Permissions on the file are 4750, owner is root, and group is nagios;
the nagios user is a member of the nagios group. The partition was
mounted with the suid option enabled. SELinux is disabled.

Hello,
occasionally our DHCP server check goes through two state changes in one
second. See below. No other service behaves this way. It makes me think
that the check_dhcp plugin sometimes sends two results in quick
succession instead of one. Or maybe Nagios runs the check twice?
It does not occu
Hi All,
I've been tearing my hair out and unsuccessfully googling this problem for what

Check the archives -- this one comes up a lot.
The short answer is that check_dhcp needs root privileges to work
correctly.

the first test just checks to see if someone gives a dhcp lease.
the second will fail unless that specific server gives a dhcp lease.
it's possible you have a dhcp server trying to give a 0 second lease or
the plugin may have a bug, are you sure it said 1 DHCPOFFER and max
lease time 0 seconds?

I suspect you want $USER1$, not $USERS1$. That error code often
