AW: SOLVED -- NRPE - Error - Could not complete SSL handsha ke

[Greg King]

Thanks for the suggestion Sven.

Yes - even though the doc says it is ignored if xinetd is used. However I had a error in the nrpe file in xinetd.d. When I corrected it, everything worked as expected.
Here's what I have in each config file:
---nrpe.cfg---
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
allowed_hosts=127.0.0.1,192.168.2.106,192.168.2.109
---/etc/xinetd.d/nrpe
    ...
    only_from       = 192.168.2.106 192.168.2.109 127.0.0.1
