handshake failed no matching key exchange algorithm #345

Closed yakir12 closed 5 years ago

yakir12 commented 5 years ago

Hi! The client is Ubuntu 18.04.1, the server is Debian 11, I can ssh fine to the server with the same settings specified in the ftp-remote-edit server settings, I can sftp and get and put files, but still get a handshake failed no matching key exchange algorithm error whenever I test the server via the ftp-remote-edit server settings. Any clue what I should try?

Thanks in advance!

P.S. I couldn't find any documentation.

Hi @yakir12,

the error message is thrown by the sftp library if no matching authentication method can be found. We use the ssh2-sftp-client library. Have you checked here if other users might have the same problem?

yakir12 commented 5 years ago

Sorry, so is ssh2-sftp-client a dependency for the client, server, or both? I installed it on both the client and server but that did not resolve the issue. Or am I supposed to do something more than just 

(sudo) npm install ssh2-sftp-client

Have you checked here if other users might have the same problem?

While there are a number of similar issues, I couldn't find one that worked for me. Apologies if I missed it (and a typo I just found in my original post).

The problem was that I had specified a specific KexAlgorithms in my sshd_config. The person who solved this was Joshua Gentry on this Discourse topic.
