Nagios nrpe on Remote host

[Alloo, Vincent]

Atul,
I don't know if it can help, but here my nrpe xinetd conf:

% cat /etc/xinetd.d/nrpe 
# default: on
# description: The rshd server is the server for the rcmd(3) routine
and, \
#       consequently, for the rsh(1) program.  The server provides \
#       remote execution facilities with authentication based on \
#       privileged port numbers from trusted hosts.
service nrpe
{
        flags                   = REUSE
        disable                 = no
        socket_type             = stream
        wait                    = no
        user                    = nagios 
        log_on_failure          += USERID
        server                  =  /apps/nagios/nrpe/nrpe 
        server_args             =  -c /db/sysadmin/nagios/nrpe.cfg
--inetd 
}
