Lab 3:
Useful links: netperf, altq-tips.txt, netperl
manual
Note: Please check lab note and useful links to understand how to use the tools for this experiment before coming for lab session.
Lab 2:
Useful links: tcpdump, tcptrace, sock options
Special Instruction: Before coming
to do this lab every group needs to find an IP address of a machine with large RTT ( >
700ms) and also
discard server running there. To
find this do ping to random machines from windows machine and pick few IP
addresses which have large
RTT. Then try to telnet those IP addresses for
port 9 or discard. If succeeds then means discard server is running there.
Command:
telnet x.y.z.w 9
or
telnet x.y.z.w discard
Useful commands:
1. To get analysis of tcpdump output (in long
format)
tcptrace -l filename
2. To get congestion window graph
tcptrace -N filename
3. To get all graphs
tcptrace -G filename
4. To send data using sock (sends
16 packets, each packet size is 1024 bytes to discard server of aludra)
sock -i -n16 aludra.usc.edu discard
5. To run tcpdump only for port 9 and get binary
output,
tcpdump -w filename -i xl0 port 9

Useful links: ifconfig, route, netstat, ping , traceroute ,tcpdump, Zebra (Please check man pages
properly and create your own configuration file for zebra).
Sample configuration files for Zebra: (zebra.conf, ripd.conf, ospfd.conf)
Lab 4: (start from

Useful links: tcpdump, tcptrace, sock options
Useful commands:
1. To get analysis of tcpdump output (in
long format)
tcptrace -l filename
2. To get congestion window graph
tcptrace -N filename
3. To get all graphs
tcptrace -G filename
4. To send data using sock (sends
16 packets, each packet size is 1024 bytes to discard server
(port 100) of 192.168.4.1 windows machine)
/bin/sock -i -n16 192.168.4.1 100
5. To run tcpdump only for port 100,
tcpdump -i xl1 port 100
6. To run tcpdump only for port 100 and
get binary output,
tcpdump -w filename -i xl1 port 100
