Comcast's phone support department is the *worst*, WORST, I've ever dealt
with. I think they are outsourced, they have to go by a script, and many of
them probably hardly know what a computer even is. Once I called because of
a problem on their network, and I told the person on the phone that
There's a tool out there called tracesroute (note the s) that will also
provide the AS number of every ip it lists.

I've got a cisco MC3810 with a bunch of DSL customers on it. CEF is
enabled, but when I do a show int stat, I see that almost 100% of the
outbound packets on the ethernet interface are process switched, and not
being matched in the route cache. The Input looks just fine, and the other

Not sure on the MC3810 (never used one), but I know that many of the
other Cisco routers didn't do CEF on ethernet until later revisions of
code... There are other factors that kick it out of CEF as well.. I

I don't think the purpose was to DoS them. It looks like some of them were
hosts on Comcast's cable network, probably some user machines being used to
host the second part of the payload.
I just want to know what the second part of this thing does. It's better
than watching TV. :)
If you're looking at the Packeteer to put some limits in place based on

What kind of metrics are you looking for? Netflow type info? How fat is

There exists an intermittent problem on your network which occurs every

everytime I call your support department, I just get someone who does not

that means you instantly need two, doubling the price.
Same thing with the Cisco CSS. Even without a hard drive, you should have 2
of them anyway.
We all hedged bets that Cisco was going to absorb the CSS and
just make it
a software feature on the Catalyst switches. I haven't heard of that
actually happening yet though.
If they did that, how would they sell the CSS hardware? :)
I would think that the closest you are going to get to
If the servers are in two separate locations, like two datacenters on either
side of the country, you are stuck with DNS-based load balancing. Like
others have mentioned, Cisco, F5 and others have products which will handle
this for you and take into account some other factors when directing
