I was wrong. That was my own Nagios server, which is running under
Ubuntu. I recently upgraded it to Ubuntu 17.04, and the nrpe plugin is
at version 3, so it tries to connect with protocol version 3 first, then
2. This gives the warnings I reported... :-)

Yes, I know. Actually the NRPE agent is using TCP wrappers, which I am
using to "protect" the agent. It's not a firewall, but it should do its
job. Thanks for the heads up! :-)
