Use the default mininet VM on VirtualBox and set up host-only adapter and internet connection.
Start the VM, run $ ifconfig to get its host-only IP address, then minimize it.
Open a terminal on the local machine and SSH into the VM using the IP address from above.
Run $ git clone https://github.com/nicholaslum444/cs4226-mininet ~/submission.
Leave the terminal open for editing files if needed.
Open another terminal on the local machine and SSH to the VM.
Navigate to pox directory $ cd ~/pox.
Create a softlink to controller file: $ ln -s ~/submission/controller.py ~/pox/pox/misc/controller.py.
Create a softlink to policy file: $ ln -s ~/submission/policy.in ~/pox/policy.in.
Run $ ./pox.py log.level --DEBUG pox.misc.controller.
Leave the terminal open so that the controller can continue running.
Ensure POX is running first; See above.
Open another terminal on the local machine and SSH to the VM.
Navigate to the submission folder $ cd ~/submission.
Run mininet: $ sudo python mininetTopo.py.
Leave the terminal open to interact with mininet.
Run POX and mininet as above.
On mininet, run > pingallfull. All hosts should be reachable. Note the RTT for the host pairs.
Run > pingallfull again. All hosts should still be reachable. The RTT of the host pairs should be significantly smaller than before.
Exit mininet once completed.
On mininet, open the xterm windows for all the hosts: > xterm H1 H2 H3 H4 H5 H6 H7.
On the xterm of H1, run: # iperf -s -D -p 4001 && iperf -s -D -p 5000. This opens port 4001 (banned) and port 5000 (allowed).
On the xterm of H4, run: # iperf -c 10.0.0.1 -p 5000 -t 5 && iperf -c 10.0.0.1 -p 4001 -t 5. The second command should not work.
On the xterm of all other hosts, run: # iperf -c 10.0.0.1 -p 5000 -t 5 && iperf -c 10.0.0.1 -p 4001 -t 5. Both commands should work.
On the xterm of H4, run: # iperf -s -D -p 4001 && iperf -s -D -p 5000. This opens port 4001 (banned) and port 5000 (allowed).
On the xterm of H1, run: # iperf -c 10.0.0.4 -p 5000 -t 5 && iperf -c 10.0.0.4 -p 4001 -t 5. The second command should not work.
On the xterm of all other hosts, run: # iperf -c 10.0.0.4 -p 5000 -t 5 && iperf -c 10.0.0.4 -p 4001 -t 5. Both commands should work.
On the xterm of H2, run: # iperf -s -D -p 1000 && iperf -s -D -p 5000. This opens port 1000 (banned) and port 5000 (allowed).
On the xterm of H5, run: # iperf -c 10.0.0.2 -p 5000 -t 5 && iperf -c 10.0.0.2 -p 1000 -t 5. The second command should not work.
On the xterm of all other hosts, run: # iperf -c 10.0.0.2 -p 5000 -t 5 && iperf -c 10.0.0.2 -p 1000 -t 5. Both commands should work.
On the xterm of H5, run: # iperf -s -D -p 1000 && iperf -s -D -p 5000. This opens port 1000 (banned) and port 5000 (allowed).
On the xterm of H2, run: # iperf -c 10.0.0.5 -p 5000 -t 5 && iperf -c 10.0.0.5 -p 1000 -t 5. The second command should not work.
On the xterm of all other hosts, run: # iperf -c 10.0.0.5 -p 5000 -t 5 && iperf -c 10.0.0.5 -p 1000 -t 5. Both commands should work.
Finally, close all the xterm windows and exit mininet once completed.
Start mininet.
On mininet, the bandwidths reported by the following commands should be representative of 100Mbps:
# H1, H4, H5
iperf H1 H4
iperf H1 H5
iperf H4 H5
# H2, H6
iperf H2 H6
# H3, H7
iperf H3 H7The bandwidths reported by the following commands should be less than 50Mbps:
# H1:x H2, H3, H6, H7
iperf H1 H2
iperf H1 H3
iperf H1 H6
iperf H1 H7
# H2:x H1, H3, H4, H5, H7
iperf H2 H3
iperf H2 H4
iperf H2 H5
iperf H2 H7
# H3:x H1, H2, H4, H5, H6

iperf H5 H7
# H6:x H1, H3, H4, H5, H7
iperf H6 H7
# H7:x H1, H2, H4, H5, H6Exit mininet once completed.
