I received a couple of weird INCOMING entries in the log.

DATE           TIME        SCR       SCR_PORT      DEST         DEST_PORT
08/25/2001 13:24:52  192.168.1.8      80          <my ip address>      3976

08/25/2001 23:25:38  192.168.1.9      80          <my ip address>      4450

My guess is that someone in your neighborhood is leaking out these
packets. Quite likely because someone is being used as amplifier.

            Don't meddle in the affairs of sysadmins,
            for they are subtle and quick to anger.
