Thanks Todd, Did a fresh install. Added the following line to sshd_config but then sshd won't come up: KexAlgorithms +diffie-hellman-group1-sha1, +diffie-hellman-group-exchange-sha1 Dennis Sent: Friday, June 17, 2016 at 7:09 PM From: "Todd C.

Newer versions of OpenSSH don't accept these weak key exchange algorithms by default: diffie-hellman-group1-sha1 diffie-hellman-group-exchange-sha1 You can add them back in /etc/ssh/sshd_config using the KexAlgorithms setting. See sshd_config(5) for details. Also see http://www.openssh.com/legacy.html - todd
