RE: Comcast Cable Setup Security Issue

["Steve Hillier" <securityfocus () mastermindtoys com>]

I have e3xperience similar problems here in Canada with Rogers Cable.
Every time you deal with tech support, one of the first things they ask
you is to disable any personal firewall software you have installed for
the duration of the support call. I was also asked to make sure my
computer was connected directly to the cable modem, not through my
router.

To add to their sins, Rogers has just recently teamed up with Yahoo! to
provide mail and personal webspace services. This is all fine and good,
except that you cannot access any of their services on-line unless you
use Internet Explorer or Netscape. So poor Opera users like myself are
stuck using an unsecure browser to view our email and maintain our
accounts on the web. (Once I get a little less frustrated, I think I'll
download Firefox and see if that makes a difference.)

Needless to say, I'm not pleased with Rogers, their "technical" support,
or their decision to alienate some of their more web-savvy users. I like
to think that I do a good job keeping my machine secure from all the wee
beasties on the Internet, but help like I get from Rogers doesn't make
my job any easier.

Guess I'll just have to switch ISPs.
