Dec 1 03:27:37 mx sshd[743]: Accepted password for mxadmin from 192.168.3.3 port 4321 ssh2


What does "Failed none " means ?

The first[1] step in the SSHv2 authentication is to request an authentication with a method of "none". If the server requires no further authentication then it must allow the "none" authentication to succeed, otherwise it must reply with a list of authentications that the server allows.


It's normal, but it's usually only logged at LogLevel VERBOSE so it doesn't normally make it to the log files.

[1] From memory I think the spec says it's optional but almost all clients implement it.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
