Name based SSH proxy
...nformation is covered by integrity checks and which is not. I found a method which would work according to the RFC, but it turns out OpenSSH doesn't behave as specified by the RFC. One thing I found was RFC 4253 saying: An implementation MUST respond to all unrecognized messages with an SSH_MSG_UNIMPLEMENTED message in the order in which the messages were received. Such messages MUST be otherwise ignored. Later protocol versions may define other meanings for these message types. However what I found OpenSSH to be doing was for every unrecognized message it would either ignore it and not...

Dear all, For my thesis, I've been working on automatic inference of state machines for SSH servers. I ran into a couple of particularities regarding OpenSSH's inferred state machine, and was hoping some of you might be interested. Maybe you can even shed some light on it. Setup: I'm using LearnLib's (Java) version of the L* learning algorithm [1] to come up with sequences of
