[Bro] Interesting observation with ssh on non-ssh port

I resolved to get monitoring of large amounts of outbound data (the 
exfiltrate and largeTx type scripts) working today.  My test setup is 
two internal machines (192.168.1.).  My hope was that I could just test 
scp'ing a file from a machine running bro.  I haven't got any scripts to 
function, so I looked at the conn.log.  Interestingly, the port I run 
ssh on doesn't show up.  I see my connected sessions fine in ssh.log, 
but there's no trace of it in conn.log.  This obviously explains why I 
couldn't get the large outbound transfer scripts working, but now I'm 
curious...is there a reason why this TCP session doesn't show up in 
conn.log?  Running bro 2.2...thank you.
