Problems with nrpe and nagios 3

[Dunn, Larry]

Good morning group!
 
I am still relatively new to nagios and trying to implement nrpe with
nagios 3 at my site.  I believe I have everything setup correctly on
both the nagios server and the client.  When I try to use check_nrpe to
run a script on the client side I am getting the error:
 
    nrpe[]: Error: Request packet had invalid CRC32.
    nrpe[]: Client request was invalid, bailing out...
 
I am running the nagios server on solaris 9 and the client is running
Redhat Linux WS 3 update 6. The version of check_nrpe is 1.9 but the
version of nrpe is 2.12.  I have the system setup to execute the nrpe
daemon through xinetd on the linux client.
 
The server_args line in the nrpe startup file under /etc/xinetd.d has
the following arguments listed per a suggested issue on the internet
asking to redirect standard error to /dev/null:
 
    server_args    = -n -c path_to_nagios/etc/nrpe.cfg --inetd 2>&1
/dev/null
 
Also my only_from config is setup to allow the client to receive
requests from the nagios server only.
 
    only_from       = ipaddress_of_nagios_server
 
 
Any help or suggestions are appreciated.
