Hi @std
On my instance I can find this particular check in $OMD_ROOT/lib/nagios/plugins. As
far as I can see, the permissions are as follows:
-rwxr-x--- 1 root omd 269480 Apr 14 19:08 check_icmp*
Owner is root, group is omd. In my installation, the setuid bit isn’t set, but it probably works because it’s owned by root. Try finding out where your check_icmp plugin is located and inspect its permissions.
HTH,
Thomas
