      I'm curious if anyone else has been getting port 109 SYN/FIN
scan's lately? (src 109 -> dst 109).  I've gotten them from two separate
sources, several days apart (looks like a sequential scan of multiple
class A networks), and I thought it was a bit odd, since last time I
heard, POP2 was a virtually abandoned protocol (at least I've never seen
it in use, and I've been mucking around on the net for a long time now),
and in this day and age, a SYN/FIN scan is almost certain to set off
IDS's.

        I haven't seen any scans, but I know there are some agencies that
unwittingly do have POP2 enabled.  As recent as 1996, Sun Microsystems was
shipping Netra i systems (Solaris 2.4) with POP2 enabled.  Unfortunately,
those "easy-to-use" systems often fell into the hands of people who just
plugged 'em in, turned 'em on, and dropped them on the 'net.  Offhand, I'd
guess that there are at least a half-dozen Netra i's still running (and
probably with their default installs) where I used to work full time.
