SSH-MITM
Server for security audits supporting public key authentication
...This allows SSH-MITM to accept the same key as the destination server. If publickey authentication is not possible, the authentication will fall back to password-authentication. When publickey authentication is possible, a forwarded agent is needed to login to the remote server. In cases, when no agent was forwarded, SSH-MITM can rediredt the session to a honeypot.
