Ping check is failing..Can you let me know how do i get this working?

This is most likely a permissions issue. Can you verify the permissions on the "check_icmp" plugin, and correct them if necessary?

The same issue and a solution to the problem are described in the forum post below:

Let us know if this helped. Thank you!

I changed the permission as listed in the link you sent:
The permissions are changed to:

r-sr-sr-t

Howerver it still does not work

Hello, This issue still persists. I don't know what i am missing.Can you please help me?

I also get this:


Warning: This plugin must be either run as root or setuid root.

These are the correct permissions (from a clean install of Nagios XI):

Code: Select all

ls -la /usr/local/nagios/libexec/check_icmp
-rwsrwxr-x 1 root nagios 191923 Jul  2 00:34 /usr/local/nagios/libexec/check_icmp

Make sure that your permissions are the same, then test running the plugin from the CLI, for example:

Code: Select all

/usr/local/nagios/libexec/check_icmp -V

Did this help?

[nagios@nagios3 libexec]$ ls -la /usr/local/nagios/libexec/check_icmp
-r-xr-xr-t. 1 root nagios 182123 Apr 9 2016 /usr/local/nagios/libexec/check_icmp
[nagios@nagios3 libexec]$ /usr/local/nagios/libexec/check_icmp -V

Nope its says u need to sun as root

[nagios@nagios3 libexec]$ ls -la /usr/local/nagios/libexec/check_icmp
-r-xr-xr-t. 1 root nagios 182123 Apr 9 2016 /usr/local/nagios/libexec/check_icmp

Your permissions are NOT the same as the ones I showed you. I would recommend running the command above (outlined in red) in order to fix your problem.

Example:

Code: Select all

chmod u+s /usr/local/nagios/libexec/check_icmp

[smapple]

[nagios@nagios3 libexec]$ sudo chmod 775 check_icmp
[nagios@nagios3 libexec]$ /usr/local/nagios/libexec/check_icmp -V
