So your daemon seems to work Any reasn you want to use Inetd instead?

Seems like you set up xinetd to use the nrpe configuration as an xinetd
configuration. It would be analogous to running Apache httpd with
Nagios's configuration: it just can't work.

You'll have to read more about Xinetd to set it up. Alternatively you
can run nrpe as a stand-alone daemon (as the first command above) and it
should work.

That is actually configured on the remote server in NRPE. Then on the
Nagios server you run:
/path/to/check_nrpe -H <hostaddress> -c check_disk1

You need NRPE running only on the remote systems, and check_nrpe on the
Nagios server. In practice though I run NRPE on the Nagios server too so
that my commands are defined the same way for both remote and local servers.
