TShark is a network protocol analyzer. It lets you capture packet data from a live network, or read packets from a previously saved capture file, either printing a decoded form of those packets to the standard output or writing the packets to a file. TShark’s native capture file format is libpcap format, which is also the format used by tcpdump and various other tools.
Without any options set, TShark will work much like tcpdump. It will use the pcap library to capture traffic from the first available network interface and displays a summary line on stdout for each received packet.
What tshark is capable.
TShark is able to detect, read and write the same capture files that are supported by Wireshark. The input file doesn’t need a specific filename extension; the file format and an optional gzip compression will be automatically detected. tshark is a detailed description of the way Wireshark handles this, which is the same way Tshark handles this.
If the -w option is not specified, TShark writes to the standard output the text of a decoded form of the packets it captures or reads. If the -w option is specified, TShark writes to the file specified by that option the raw data of the packets, along with the packets’ time stamps.
When writing a decoded form of packets, TShark writes, by default, a summary line containing the fields specified by the preferences file (which are also the fields displayed in the packet list pane in Wireshark), although if it’s writing packets as it captures them, rather than writing packets from a saved capture file, it won’t show the “frame number” field. If the -V option is specified, it writes instead a view of the details of the packet, showing all the fields of all protocols in the packet.
With tones of options , permentation and combination we can do mant thing. Yes we can call it a tradisnal ump and analyze network traffic but with much added flavors.
