Sorry guys, by the replies i'm getting i think i wasn't
clear enough in my first post. Thanx to all that replied,

By successful connection i meant a client successfully autheticating, 
i.e. getting a shell (could also be getting a port redirected, by i
don't actually use that in my setup).

After a successful login via ssh (brute-forcing a password,
or any other means) an attacker could escalate to root and
wipe the syslog. If he were to kit me, the only ways i would
have to know that something fishy was going on would be by
the tripwire check (that i do less often than i should) or
by the odd trafic that he would generate.

So basically i would want snort to be able to tell me something
along the lines of: ip x.x.x.x logged on to DMZ1 using ssh.
