Re: Increase in Sub7 scans

Generally speaking, most kids at home have more bandwidth to play with 
then they do at school.  The average school might have a T1.  Some might 
have a couple.  Most of the schools I've dealt with only have a 256, 512, 
or 768k frame-relay connection.  The ones that have a T1 to play with 
barely touch it.  I've gotten over 2Mb/sec out of my cable modem here in 
a podunk corner of Kansas.  I got even better from SWB DSL before I 
moved.  Dialup is on the decline for the most part.  DSL/Cable is on the 
rise.  That at least holds true to parents with kids or reasonably saavy 
college kids.  The only people I've found to be buying dialups are people 
who can't afford cable/dsl at the moment, are beginners and they don't 
think they need the glory of something faster, or they realize that all 
they'll do is send email and view a few webpages.  Most everyone else 
(that can get it) goes for something with a little more umph.  The 
University I currently work for only has 2 T1s.  We got the 2nd in 
December.  This summer we'll go to 6 I-MUX.  That's my take on the 
situation.

Cheers,
  Justin

FWIW, the number of port 111 probes I've logged have more the quadrupled 
since mid May.

School's out!  :-(

Eh? Is this the collective experience of others? I would have thought
the exact opposite, what with high-bandwidth connections at most schools
but not at home.

Respond to me privately, I'll summarize.

Since February, I've been receiving tcp port scans for the default sub7 
port
(27374) at a rate of approximately 3-4 per day.  Starting on June 8th to
present, I've been receiving them at 9 times that rate.
