    Sorry. None of the two medications did solve the problem on neither of my two computers.

    Yeah, this didn’t work for me either. I still have to wait 10-15 seconds for it to ask for a password. This is on my local network behind my firewall.

    I finally got this fixed with a slightly different approach.

    Added that config to the client and all is good now.

    You can also speed it up with a UseDNS no in sshd_config. (OpenSSH FAQ)

    or you can add the remote ip and host to your hosts (/etc/hosts) file.

    Just give it a name u want if u cant resolve the host name of the ip.
