Section 2: finding a cisco router
Finding a cisco router is a fairly easy task, almost every ISP will route through at least one cisco router. The
easiest way to find a cisco router is to run a traceroute from dos (type "tracert" and then the IP address of
anyone's computer), you can trace pretty much anyone because the trace will show all of the computer systems between your computer and their computer. One of these systems will probably have the name "cisco" in it's name. If you find one like this, copy down it's IP address.

Now you have the location of a cisco router, but it may have a firewall protecting it, so you should see if it's
being blocked by pinging it a couple times, if you get the ping returned to you, it might not be blocked. Another way is to try to access some of the cisco router's ports, you can do this simply by using telnet, and opening a connection to the router on port 23.. If it asks for a password, but no username, you are at the router, but if it wants a username aswell, you are probably at a firewall.
