In my case i.e "/usr/sbin/exim" , i have already set that path in script.

Ok, let's check sudoers and make sure it's a valid configuration:

sudo -v

Getting no output.

Ah, I think I see, change your /etc/sudoers entry from this:

Code: Select all

nagios          ALL=NOPASSWD:/usr/sbin/exim

To this:

Code: Select all

nagios          ALL=(ALL) NOPASSWD:/usr/sbin/exim

It's because it's trying to sudo -u (run it as a different user).

I have change it as per your direction but no effect.

Moreover i have using xinetd on client machine:

Code: Select all

cat /etc/xinetd.d/nrpe 
# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
        flags           = REUSE
        socket_type     = stream
        port            = 5666
        wait            = no
        user            = nagios
        group           = nagios
        server          = /usr/sbin/nrpe
        server_args     = -c /etc/nagios/nrpe.cfg --inetd
        log_on_failure  += USERID
        disable         = no
        only_from       = NMS IP Address
}

I have also restart both services nrpe and xinetd after any change.

Try running these commands on the remote server and see what the output gives you:

Code: Select all

su - nagios
/usr/bin/sudo -u root /usr/sbin/exim -bpc

Essentially, what it does is it runs that command and puts the output into a variable, it then checks the variable to see if the output is NULL and if it is it throws the error you are seeing.

root@server [~]# cat /etc/passwd | grep nagios
nagios:x:988:984::/var/spool/nagios:/sbin/nologin

Code: Select all

root@server [/usr/lib64/nagios/plugins]# sudo -u nagios exim -bpc
exim: permission denied

Can you try changing your /etc/passwd for nagios to:
- Note: You may need to change /bin/bash to whatver the location is of the executable.

Code: Select all

nagios:x:988:984::/var/spool/nagios:/bin/bash
