Got the following error: CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

Client:
nmap -p 5666 192.168.1.10

5666/tcp open nrpe

but other servidor : I (0.3.9.327 2011-08-16) seem to be doing fine...

In nagios server:
nmap -p 12489 192.168.1.10
12489/tcp open unknown

Are you trying to pass arguments in your commands? Have you change the following line in the nrpe.cfg file from this:
to this:

CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

Did you check the logs on the remote box?
