How to install Wireshark to monitor your network – or use with NMAP packet scanner
Step 1 – Download Wireshark
Run as Administrator
Step 2 – Install
Disk space needed is 112 mb
Choose if Start Menu or Desktop Icon is preferred
By default it installs into the directory c:\ Program Files\ Wireshark
Install WinPcap – as Wireshark won’t work otherwise
Step 2 – Install WinPcap
Wireshark won’t install unless WinPcap is installed. Watch out for a second install to be launched. If you’re not looking for it, you could miss it.
Wireshark will now completely install for you.
If the install hangs half way through, it’s because WinPcap has not been installed yet.
Start > All Programs > Wireshark Icon
Select your Interface (ie Wired or Wireless)
Then Capture Options
Promiscuous Mode > Start
Promiscuous mode means that it picks up packets and data for all devices on the network
That’s it – Wireshark will now listen in to all transmissions
Wireshark launches – by default it’s split into 3 panes
The top pane shows IP’s & protocols
You can filter these results by protocol and by IP, and I’ll cover that another time.
For now, select the Protocol header – and your results will sort by protocol.
HTTP ONLY is now displayed
It’s File > Quit to exit.
