nrpe won't connect - contradictory messages in log

[Whit Blauvelt]

Hi,

This is with nrpe-2.12, built from tar:

On the remote host:

daemon.log:Jul 28 13:22:42 system2 nrpe[7460]: Starting up daemon
daemon.log:Jul 28 13:22:42 system2 nrpe[7460]: Listening for connections on port 5666 
daemon.log:Jul 28 13:22:42 system2 nrpe[7460]: Allowing connections from: 127.0.0.1, 192.168.250.1
daemon.log:Jul 28 13:22:52 system2 nrpe[7470]: Host 192.168.250.1 is not allowed to talk to us!
daemon.log:Jul 28 13:27:46 system2 nrpe[8013]: Host 192.168.250.1 is not allowed to talk to us!

On the main nagios system:

root at system1:/opt/nagios/plugins# ./check_nrpe -H 192.168.250.2 -c check_swap
CHECK_NRPE: Error - Could not complete SSL handshake.

root at system1:/opt/nagios/plugins# ./check_nrpe -n -H 192.168.250.2 -c check_swap
CHECK_NRPE: Error receiving data from daemon.

I'm see other discussions here that suggest there could have been a
compile-time problem with the SSL libraries. I'll check that. Even if turns
out so, should that effect connecting without SSL, as in the last example?
These two boxes are connected by direct cable, no need to encrypt. And
they're exchanging other traffic constantly on this link, so it's known
good.

What's with the contradiction between "Allowing connections from: 127.0.0.1,
192.168.250.1" and "Host 192.168.250.1 is not allowed to talk to us!"? It
seems on the surface like that second message is wrong - that host
192.168.250.1 obviously _is_ allowed to "talk to us," but the transaction's
failing on another level. Is there a bug here in the choice of error message
to present?

Thanks,
Whit
