I am using the most verbose debug option of ssh (concretely: OpenSSH_8.2p1) ssh -vvv
and I am wondering what information the output exposes.
Of course the output contains the username and the server one is trying to connect to, however there is quite a lot more.
What information is exposed by this debug information? What could an attacker do with this information?
For example, would it be safe to send the output to a service desk or ask in an internet forum for help with a problem and giving the output of ssh -vvv
without replacing some information? Would that allow or help a third party to access the server, break the encryption, etc.?
