Enable fetching known host key automatically if left blank (if feasible)

[canedmonkey]

Hi,

Thanks for this app and all the hard work.

Please could you provide some info on what should go into the 'Known Host Key' field. In my experience the known host file is created by the ssh client when first connecting so I've no idea what key goes in one. I tried it with the Public Key that i generated and placed on the server but I still get 'Not in Known Host File' error

Thanks

Generally the easiest way to get the host public key - if you're using OpenSSH on the server (which people mostly are) is from one of the .pub files under /etc/ssh. A host can have multiple keys in different formats but a good choice would be /etc/ssh/ssh_host_ed25519_key.pub

For example, that file might contain something like:

ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIETq1gBzwvN2I9W/RM4b16hjTpOW76HEoKVadR/pyc6c root@server

To change this into 'known_hosts' format you should remove the comment from the end and add the server name at the start:

server.example.org ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIETq1gBzwvN2I9W/RM4b16hjTpOW76HEoKVadR/pyc6c

Let me know how you get on.

Perfect, thank you

I've reopened this as a reminder to see if there is a way to tweak the app to be able to fetch the host key automatically, not quite sure but seems worth some thought.
