How to resolve "/bin/ping Unknown status" problem in nagios

Nagios is a free and open source computer-software application that monitors systems, networks and infrastructure. Nagios offers monitoring and alerting services for servers, switches, applications and services. It alerts users when things go wrong and alerts them a second time when the problem has been resolved.

Some times we may get a ping error in newly installed nagios.

This is simply a permission problem caused by the script /bin/ping.

So the problem can be solved by running the below command.

#chmod u+s /bin/ping
