Define session? One single TCP connection? If that is what you mean, then
you are dead wrong. OpenSSH for one sets the TOS flags for a TCP connection
*after* it has logged in successfully. This provided some weird behaviour in
interacting with multipath uplinks, as suddenly the (already set up)
connection got routed out a different interface.
Doei, Arthur.
