Hi guys, and another feature request for sshd which I would classify as really useful. And I think this behaviour is currently not available (If yes, sorry, I must have missed it): > I believe that the sshd should log which RSA key was used to connect to > an account. When there are a number of keys in the authorized_keys file > it is often useful to know which one was used for each
