Hi Karen, I found a reference at Dreamhost wherein a user says that Support hold him that "diffie-hellman-group1-sha1 was recently removed for security concerns". This is 26 days ago. The reference URL is: https://discussion.dreamhost.com/t/ssh-issue-with-key-exchange-algorithms/68... It may be that your SSH client does not support newer DH modes, for example group 14. Is there a way you can find out what key exchange modes and ciphers your SSH client supports? Regards, Mike On 10/2/18, Karen Lewellen via talk <talk@gtalug.org> wrote:
Hi folks, The accessible ssh client I use provides a way to send dh keys when I use ssh TELNET to reach a location. I have a bell dsl account, and since the first of July I have not been able to reach dreamhost who hosts my office shell. While I have not ruled out Bell as the problem, it started one day when they claimed to have a service interruption, and refuse to discuss Linux at all, I want to see if something else might have happened. With very few exceptions, every place where I visit involving port 22 presents the same dh key exchange failure. Was openssh updated on June 29 2018? Hosting companies who use some different Linux options for their shell services, scientific for example, still work. Shellworld does too, but we use a different port for ssh and the administrator still allows most public keys. can anyone provide wisdom here? Thanks, Karen
