It's an academic paper. The best antedote would be to publish a nicely
researched reply paper.
Meanwhile, I'm probably one of those guilty of too large a reduction of
TTLs. I remember
there are many sites and isps like mit and kaist. there are few

Totally agreed. The paper
You could setup a Linux/Solaris (or other) device (It would need
to be GigE capable) and span all of the data to that port and then use
either iptables/ipchains to log the data and drop what don't need or use
ethereal/tcpdump to capture the data using filters to weed out the

Thanks for all the replies. The best solution was by Boyan Krosnov who
suggested the following:
Configure the GE port where the traffic comes in from the fiber tap in a
separate new vlan A, access mode.
Configure fastethernet X to be in access mode for vlan A.
Configure a static mac entry for vla
Just a suggestion, but make sure that your mail servers have the correct reverse DNS. AOL has been rejecting mail for any mail servers that have incorrect or no reverse DNS entries.

You might be able to do what yo want by hard-coding the CAM entries in the
catalyst so that it forwards the MAC addresses you're concerned about to
the port in question, but, that may or may not achieve what you want,
depending
on the makeup of the MAC addresses in the 300mbps traffic and whether

I think you're confusing your OSI layers here, routers route and

If you're spanning 300 megabits per second, what you'll need is a
gigabit card for the span port on the 3550 (or directly connected to
the passive tap you've installed).
