Permission denied nrpe error

[Mukarram Syed]

Thanks Marc for your response.  I changed the
following:

Here is my new /etc/xinetd.d/nrpe file

-rw-r--r--    1 root     root          427 Nov 16
14:23 nrpe

# default: on
 # description: NRPE
 service nrpe
 {
         flags           = REUSE
         socket_type     = stream
         wait            = no
         user            = nagios
         server          =
/usr/local/etc/nagios/libexec/nrpe
         server_args     = -i
/usr/local/etc/nagios/etc/nrpe.cfg
         log_on_failure  += USERID
         disable         = no
         only_from       = 127.0.0.1 10.0.250.20
 }

I changed the path of the nrpe.cfg file and put the
file name.  When I do this from the remote host
(nagios server, gaia):

gaia# ./check_nrpe -H triton -p 5666
CHECK_NRPE: Error receiving data from daemon.

On the client (triton), I am getting the following
errors in the /var/log/messages:

Nov 16 14:40:11 triton nrpe[31973]: Unable to open
config file '//nrpe.cfg' for reading 
Nov 16 14:40:11 triton nrpe[31973]: Config file
'//nrpe.cfg' contained errors, bailing out...

Here is the permissions on the nrpe.cfg (it is set to
777):

[root at triton xinetd.d]# cd /usr/local/etc/nagios/etc
[root at triton etc]# ls -lart
total 12
drwxr-xr-x    4 nagios   root         4096 Nov 16
14:21 ..
-rwxrwxrwx    1 nagios   root          605 Nov 16
14:21 nrpe.cfg
drwxrwxrwx    2 nagios   root         4096 Nov 16
14:22 .

Also, I read in the users list that it could be a
problem with the checkcommands.cfg file.  Here is
mine:

# 'check_nrpe' command definition
define command{
        command_name    check_nrpe
        command_line   
/usr/local/etc/nagios/libexec/check_nrpe -H
$HOSTADDRESS$ -C $ARG1$

When I run the following command from gaia (server) to
triton (client) is get the output as shown:
gaia# ./check_nrpe -H triton -p 5666
CHECK_NRPE: Error receiving data from daemon.

Help is appreciated.

Thanks
