nrpe won't connect - contradictory messages in log

Dear Richard,

Curious. In the present case both systems had NRPE compiled on the same day
with the same flags from the same tar. But one of the systems - the client
in this case - does have an older, inactive installation of Nagios on it.
Looking at NRPE's config log, it doesn't look like NRPE picked up anything
from that. And the directories used are totally different. Nor was any
version of NRPE installed before.

I'm leaning towards the guess that NRPE has a bug when compiled in the
current Ubuntu Hardy environment, and concluding that since I'm not changing
that environment soon, I'd better use SSH instead.

Thanks again,
Whit
