I have a issue with Nagios-server-nrpe.
Server is running Ubuntu 18.04 with nagios-server-nrpe version 3.2.1.
Client is running Ubuntu 16.04 with nagios-server-nrpe version 2.15
So it can't handshark together with dh key too small.
Everyone can help me fix this issue. offer a solution to replace.

Hello,

New security features were added in version 3. You can either upgrade the client to version 3 or try using the -2 option in your check command to force version 2 packets.
