Cisco vs. 6.9

[Kash, Howard M CIV USARMY ARL (US)]

As another data point, Cisco devices are also unable to scp to a system running version 6.8.  So the incompatibility was introduced between 6.7 and 6.8.

I've been debugging all day and it seems like 6.8 is skipping or adding an extra increment to the packet sequence number.  The debug output from 6.7 has:

  MAC #6 ok
  done calc MAC out #7
  MAC #7 ok

but 6.9 skips #7 and goes to 8:

  MAC #6 ok
  done calc MAC out #8

This is when the connection is closed by the Cisco device.
