As a followup to this, I've been informed by two people now[*] that Linux
boxes will respond to SYN|FIN with a SYN|FIN|ACK on an open port.
Therefore this probably indicates that the SYN|FIN packets were not only
an attempt to get past poorly designed firewalls, but probably an attempt
to ID the system being probed as a Linux box as well.
