Message type 80 is SSH_MSG_GLOBAL_REQUEST, and RFC4254 section 4 says "Note
that both the client and server MAY send global requests at any time, and
the receiver MUST respond appropriately."

Any idea what the message is?  It'd be nice if the client showed the whole
packet, but failing that you could build a server with "./configure
--with-cflags=-DPACKET_DEBUG" then pick the packet out of the server-side
debug logs.

The only global message I can think of is the protocol keepalives, in which
case you could try setting "ClientAliveInterval 0" in sshd_config to see if
that helps.

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