Questions about inferred state machines for OpenSSH
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

Bug report: first_kex_packet_follows behaviour seems wrong
...ansport-24, page
19, where the behaviour of first_kex_packet_follows is specified.
I've got an ssh client that sends an SSH_MSG_KEXINIT message and specifies
only 'diffie-hellman-group1-sha1' as key exchange algorithm. It sets
first_kex_packet_follows to true, and immediately sends the
SSH_MSG_KEXDH_INIT message. The ssh server (openssh-3.9p1) specifies three
key exchange algorithms in its SSH_MSG_KEXINIT message:
'diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellm
an-group1-sha1'. This results in diffie-hellman-group1-sha1 being the
algorithm used. So, I would thin...

Silly question on DH key exch in ssh
...at to send then?
(the hint from Markus Friedl with kexdh.c didn't help me much because I'm
not familiar with c++
and I could not find a line of code where neither the server is expecting
another message after
sending SSH_MSG_KEXDH_REPLY nor where the client is sending another message
after
SSH_MSG_KEXDH_INIT. (before sending SSH_MSG_NEYKEYS))
Thanks a lot,
S. Gloeckner
