Step 4: If We want to continue the live capturing then we can keep capturing the packet and if we want to stop capturing then we can click on stop capturing packet menu in the toolbar. Wireshark will keep capturing live packets untill we stop capturing. Step 3: Once we select the interface then Wireshark starts capturing packets and showing the list of packets and live to capture packet window. Here we need to select the appropriate interface through which we want to capture the packets. Step 2: We need to start the Wireshark with administrative permission it will show the below window. Wireshark is available to download and install on all the most used platforms. Source: Download Wireshark Step 1: First we need to download and install Wireshark on our machine as per our operating system. Whenever we want to do an analysis of any data packet the the first step is to capture the packet which is coming and outgoing then we use packet analyzer tool named Wireshark. Wireshark is having a nice interface through which we can differentiate the data as per the different parameters and then we can analyze the packet transfer process. It works similar to tcpdump in linux but the problem is that there is no GUI for tcpdump.
Originally the name of the tool was Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues. It is used for network troubleshooting, analysis, software and communications protocol development, and education. You'll probably want to filter the traffic to just display the server in question.Wireshark is a free and open-source packet analyzer. Once you have all the traffic flowing past your computer's NIC, grab a packet sniffer (I actually prefer Windows Network Monitor over Wireshark) and start grabbing the packets. This will probably only work if the traffic you're trying to capture doesn't originate from the machine you're using to capture the packets, otherwise you're going to run in to some more messy configuration. If you need all the traffic, even the router, place a hub after your router and hook a computer to it. If you only have a switch, I suppose you could rig one computer as a gateway and point the second computer towards it, but that's messy. A hub will send all network traffic to all ports, where a switch will only send it to its intended destination. If you need both, hook the computers up to a hub and then to the router.
You could do this in a number of ways, the simplest of which is probably to identify if you truly need the traffic from both computers or just the traffic from a single computer. First you're going to have to get in between all that traffic.
