Note: If you are using the Ubuntu Mininet 2.0.0d4 package, it uses a slightlyĭifferent syntax for Topo() - e.g. Part 3: Mininet Command-Line Interface (CLI) Commands.Everything in its own Namespace (user switch only).Fixing error: “ Could not load the Qt platform plugin 'xcb'”.Running Wireshark with X11 tunneling and ssh.If Wireshark is not installed (command not found error).The entire walkthrough should take under an hour. The walkthrough assumes that your base system is the Mininet VM, or a native Ubuntu installation with all OpenFlow tools and Mininet installed (this is usually done using Mininet’s install.sh). And you have just located the password and username you have entered on the unprotected login page - whether or not the password and username are correct are irrelevant.This walkthrough demonstrates most Mininet commands, as well as its typical usage in concert with the Wireshark dissector. Once you get there look in the red text paragraphs and try to find what I was able to locate in the picture. Then you will right click on it and go down to 'FOLLOW' then to 'TCP STREAM'. You can see exactly what I am talking about if you follow the pictures above. Then at the far right of the packet in the info section you will see something like '.login' or '/login'. This drastically narrows the search and helps to slow down the traffic by minimizing what pops up on the screen. By filtering this you are now only looking at the post packet for HTTP.

Wireshark comes with the option to filter packets. HTTP (Hyper Text Transfer Protocol) is the protocol we will be dealing with when looking for passwords. The second step to finding the packets that contain login information is to understand the protocol to look for.
