I didn't see any ftp scans from t-dialin.net, but I did see several
tries for http (1080 and 80) as well as tries for pop servers (110).

I don't normally see a lot of scans for ftp daemons.  Usually they are
trying for http and pop servers or open mail relays.

However, checking my logs, I did see a big spike in probes for tcp port
23 between 8 and 20 Oct.  These were mainly from two subnets, sonic.net
and adelphia.net.  This activity seemed to tail off almost entirely
after 21 Oct.
