I would recommend that too. Attached is a revised version of the exploit I 
posted earlier with a couple more targets.... it also works against lsh 
running 'daemonic', ie. started as a daemon and not just against lshd running 
in the foreground.

The only caveat is that the exploit must be the first thing to connect to lshd  
otherwise the exploit becomes a DoS.

More advanced exploits that work _every_ time should be expected.
