You won't be able to telnet back from the client to the server unless 
you're also running nrpe on the server.
As long as you can telnet server to client on that port, you're fine.

Also nrpe uses TCP only (I believe.)

Like David says, try su'ing to the Nagios user and running the command 
manually.

If all else fails, please post back the following:

1. The output of "check_nrpe -H <nrpe_client> -c <remote_command>" run 
as the Nagios user
2. The Nagios command definition for your check_nrpe command
3. A Nagios service definition that uses the check_nrpe service on the 
relevant host
