nagios check_nrpe help

Hi,
I hope this is the right group for my question.
I have some problem using check_nrpe plugin in nagios.
When I try to add the -a option to add some commands option i receive
this output : " CHECK_NRPE: Received 0 bytes from daemon. Check the
remote server logs for error messages. "
I use this command from my nagios server :

../check_nrpe -H hostname -c check_load -a 1,1,1 2,2,2


When I use : "./check_nrpe -H hostname -c check_load " I receive the
correct output.
In the client machine the nrpe.cfg have the line :

command[check_load]=/usr/local/nagios/libexec/check_load -w 1,1,1 -c
2,2,2

How should I configure my nrpe.cfg and how can I pass the commands
argument through the check_nrpe plugin ?

Thank you.
Bye
