Computer Networks
Practical exercises #17
- If you're on the Bendigo campus, do a traceroute from one of the
department's Unix systems to a host outside La Trobe University.
Also try a traceroute to La Trobe's Web proxy,
proxy.latrobe.edu.au
. Which router do you think
is the one which blocks ougoing TCP port connections to port 80 ?
This may need some thought!
- Many businesses with Internet connections use any or all of
circuit-level gateways, application gateways and packet filtering
firewalls. Can you discover any? If you're outside La Trobe
University, can you discover if your connection to the Internet has
any firewall characteristics? NB: It is regarded as
extremely rude to attempt to establish connections
to systems where they are obviously not wanted. Use lots
of caution!
- Look up some firewall-related
web sites.
