Installing tshark Only. Note: If you have not used tshark before, you should install the wireshark package as above before limiting yourself to the CLI. If you want to install just tshark and no Qt/GUI components, this is possible on various linux distributions. The package is called tshark or wireshark-cli depending on the platform.

with the advent of ipv6, these columns are hard to quickly identify with a particular system. I was wondering if there is an option to use the 'ethers' table, when an entry exists, in place of the ip address in either the source or destination columns? asked 17 Jul '13, 14:15 proj964 edited 18 Jul '13, 06:08 cmaynard ♦♦ |
If you want to show the MAC addresses, or the names corresponding to the MAC addresses, in the columns in the packet summary, go to Edit -> Preferences, select 'Columns', and for the 'Source' and 'Destination' columns, select 'Hardware src addr' and 'Hardware dest addr', respectively. To get the addresses mapped to names, however, you'll have to add the names to the 'ethers' file; that will not happen automatically, except in cases where packets such as ARP packets, allowing Wireshark to infer the MAC address to IP address mapping and thus to translate the IP address to a host name, are in the capture. (No, Wireshark does not automatically map MAC addresses to host names.) This will, of course, not give useful information for packets that didn't originate and terminate on your LAN segment, but that are being routed through your network. answered 17 Jul '13, 23:03 Guy Harris ♦♦ |

This article will explain how to use wireshark to capture TCP/IPpackets. Specifically I will show how to capture encrypted (HTTPS)packets and attempt to document the 'dance' a client and server do tobuild an SSL tunnel.
What is Wireshark?
Wireshark is a network protocol analyzer for Windows, OSX, and Linux. Itlets you capture and interactively browse the traffic running on acomputer network. Similar software includes tcpdump on Linux.
Install Wireshark
First step, acquire Wireshark for your operating system.
Ubuntu Linux:sudo apt-get install wireshark
Windows or Mac OSX: search for wireshark and download the binary.
How to capture packets
This is Wireshark's main menu:
To start a capture, click the following icon:
A new dialog box should have appeared. Click start on your preferredinterface:
You are now capturing packets. The packet information is displayed inthe table below the main menu:
Now browse to an HTTPS website with your browser. I went tohttps://linkpeek.com and after the page completely loaded, I stopped theWireshark capture:
Depending on your network, you could have just captured MANY packets. Tolimit our view to only interesting packets you may apply a filter.Filter the captured packets by ssl and hit Apply:
Now we should be only looking at SSL packets.
Next we will analyze the SSL packets and answer a few questions
1. For each of the first 8 Ethernet frames, specify the source ofthe frame (client or server), determine the number of SSL records thatare included in the frame, and list the SSL record types that areincluded in the frame. Draw a timing diagram between client and server,with one arrow for each SSL record.
2. Each of the SSL records begins with the same three fields (withpossibly different values). One of these fields is “content type” andhas length of one byte. List all three fields and their lengths.
