Just found the e-mail for my dreamhost contact. Will share all of your brilliant deductions with them. My only guess now is that there is something wrong with how my account is configured on their eugene.dreamhost.com server, since elementary, security and keys should work the same through out! Thanks so much. Kare Watson On Thu, 4 Oct 2018, Mike wrote:

Got it! So you can definitely connect outbound on port 22! And yes, I was probing dreamhost.com on port 22. They got some 'splaining to do. I suggest you might want to hit up their support folks again armed with the information that your SSH client is using:

diffie-hellman-group-exchange-sha1 OR diffie-hellman-group1-sha1 for key exchange, ssh-dss for host key, and aes128-cbc and hmac-sha1 for session encryption.

Good luck, Watson! Let us know what explanation they offer...

Cheers, Mike
