check_icmp issues warning and does not run

[Nguyen, Tham]

Okay the problem is solved.

 

Before I had this in the localhost.cfg:

 

define service{

use                                           generic-service

host_name                                sun-ae-server001

service_description                     ICMP

check_command                       check_nrpe!check_icmp

}

 

Changed this line check_nrpe!check_icmp to check_icmp and it worked fine.

 

The setuid bit works though; just the config file is not set properly.  The error message (Warning: This plugin must be either run as root or setuid root ) is ambiguous!!!

Thanks Mathieu for your response.  However, after changing the setuid bit, I am still receiving the same error message (chmod u+s check_icmp).

 

-rwsrwxrwx 1 root   root    85170 May 15 16:26 check_icmp

 

 

ICMP   UNKNOWN   05-29-2008 13:42:24   0d 0h 22m 58s   3/3   Warning: This plugin must be either run as root or setuid root.

This file is OWNED by "root", not RUN as "root".

Your Nagios process is probably running as "nagios". Therefore 

"check_icmp" is run as "nagios", not "root" by the Nagios process.

 

My understanding is that you should change the file's permission and set 

the "setuid bit" in order to allow "nagios" to run this file as "root".
