#947: Incorrect size calculation for SSH failed/successful heuristic
------------------------+---------------------
 Reporter:  grigorescu  |       Type:  Problem
   Status:  new         |   Priority:  Low
Milestone:  Bro2.2      |  Component:  Bro
  Version:  git/master  |   Keywords:
------------------------+---------------------
 We're getting a lot of false positives for successful SSH logins from a
 source that we recently blackholed. I suspect what's happening is that the
 retransmissions keep bumping up the size of the connection, until it
 crosses the threshold for a "successful" connection.

 With the changes from #730: Find and fix tcp sequence counting bugs, is it
 possible to improve the accuracy of the reported size?
