com.jcraft.jsch.JSchException: UnknownHostKey

by

I would either:

  1. Try to ssh from the command line and accept the public key (the host will be added to ~/.ssh/known_hosts and everything should then work fine from Jsch) -OR-

  2. Configure JSch to not use “StrictHostKeyChecking” (this introduces insecurities and should only be used for testing purposes), using the following code:

    java.util.Properties config = new java.util.Properties(); 
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);

Option #1 (adding the host to the ~/.ssh/known_hosts file) has my preference.
