April 18, 20233 yr Hey Gang, I'm a very novice linux user, just know enough to get around and follow instructions for the most part. I recently started getting the following error when trying to ssh to my armbian box from an up to date macbook. Unable to negotiate with <ip address> port 22: no matching host key type found. Their offer: rsa-sha2-512,rsa-sha2-256,ecdsa-sha2-nistp256,ssh-ed25519 I've read online that you can get around this with "-oHostKeyAlgorithms=+ssh-dss" temporarily, but I cant seem to find a guide on how to regenerate the host keys on armbian to match more current standards (or what I assume is ssh's up to date minimum) Does anyone have a quick guide on how to do this? Currently running: Welcome to Armbian 23.02.2 Jammy with Linux 5.15.93-rockchip64
April 18, 20233 yr Armbian does not mess with ssh settings besides allowing root login. It uses default values that userspace packages ship. Therefore also hostkey generation is straight forward as plain Debian/Ubuntu on x86.
April 18, 20233 yr Author Thank you for the response Werner. Do you think this is an issue on my client (MacOS) or the server (Armbian/Ubuntu) side?
