Is it really running and listening on all interfaces?
netstat -lnp | grep -i nrpe

Make sure to enter all the "allowed_hosts=" in your nrpe config.
Try entering the real ip of the machine you want to check even though you run  
check_nrpe  from the same machine.
For example if the address of the machine is 192.168.0.5 add this ip to the 
allowed hosts.

Hope that helps.
