SSH session logging

NETCONF
1

Hello,

Is there a way to enable more verbose SSH session logging that displays the SSH authentication and encryption algorithms were negotiated for the session?

For example, something like the ssh -vvv output.

debug1: SSH2_MSG_KEXINIT sent
debug1: SSH2_MSG_KEXINIT received
debug1: kex: algorithm: curve25519-sha256
debug1: kex: host key algorithm: ssh-ed25519
debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: compression: none
debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: compression: none
debug1: expecting SSH2_MSG_KEX_ECDH_REPLY
debug1: Server host key: ssh-ed25519 SHA256: …

Best Regards,
Matt

The built-in SSH daemon does not log that info. You would have to use an external SSH server such as OpenSSH if you want the SSH daemon to log that info.
