Cox and Linux - info needed

[Jeffrey Pyne]

Technically, Cox' ToS makes running any services verboten.  However, near as
I can tell, they are not doing any port filtering to prevent this.  They do
port scan occasionally, but it always comes from an IP address (usually the
same one) in the 24.x.x.x block.  So, theoretically, one could have web,
mail, DNS, etc. running on a segment on one's LAN.  And one could
theoretically have, for example, an OpenBSD firewall that allows access to
these services in your "DMZ" by redirecting this traffic with ipfilter and
ipnat.  And one could theoretically block access from the entire 24.x.x.x
block (one might block the whole range just in case Cox decided to change
the host from which they do their port scanning-- although they haven't in a
while).  So if Cox were to theoretically scan your theoretical IP address
looking for theoretical services, none would appear (in theory).  And if one
had friends or family on the 24.x.x.x block (e.g. Sprint/Speedchoice users,
or other Cox users), one could, in theory, put a rule in this theoretical
OpenBSD firewall to allow the specific IP address of these friends/family to
access your theoretical services.  Not that _I_ would *ever* do this, mind
you.  It's against the ToS, after all.  ;-)  ("Nudge, nudge, wink, wink.
Say no more....  A nod's as good as a wink to a blind bat.")

So if you want to run services on Cox' network, it can be done.  However, if
you want to have more than just a personal web server that you and your
friends and family access from time to time, and your site is going to be
generating lots of traffic, you should probably go with Cox @Work.  Same
network (I think), it just costs more.  But services are "allowed."

Theoretically yours,
Jeff

Thanks for the Qwest info.  It would seem Qwest "is less than optimal" 
for running web/DNS/mail at home.  What about Cox@home?  Is it any 
better for this?

I had a really good experience with cable in Hawaii (typically > 2mbit,
sometimes as high as 5mbit), yet L.A. blew chunks (typically 15-20Kbit
and totally useless Friday/Saturday night).  I have 640K ADSL from Qwest 
now (in A.J.) and I love it (except for the Intel 2100 WinCableModem).

George
