Update Wireshark on Ubuntu Terminal

Wireshark is a powerful tool for capturing and analyzing network packets. In this guide, we will show you how to update Wireshark on your Ubuntu terminal.

To start, you can use dumpcap, which is part of Wireshark, to capture packets without the need for a graphical user interface (GUI). To do this, open your terminal and type:

`dumpcap -i -b filesize:100000 -b files:20 -w mycapture.pcapng`

update wireshark ubuntu terminal

This command captures packets in a ring buffer, allowing you to capture packets continuously without exhausting disk space. The `-i` flag specifies the interface number, which can be listed using `dumpcap -D`. The `-b` flag sets the file size and number of files, while the `-w` flag specifies the output file.

You can also use dumpcap with the `-h` flag to see all available options.

For example, if you want to capture packets on a specific interface, you can type:

`dumpcap -i 1`

This will start capturing packets on interface number 1.

If you want to filter traffic within any of the private network spaces, you can use the `tcp.port` or `udp.port` filters. For example, to see all traffic on port 80, you can type:

`tcp.port=80`

You can also use display filters to see specific types of packets. For example, to see all incoming and outgoing traffic for a specific address, you can type:

`display filter ip.addr = 1.2.3.4`

Replace `1.2.3.4` with the relevant IP address.

To exclude packets from a specific IP address, you can use the following filter:

`ip.addr != 1.2.3.4`

You can also use display filters to see traffic going to or coming from a specific address. For example, to see all incoming traffic for a specific address, you can type:

`display filter ip.src = 1.2.3.4`

To see all traffic going to a specific address, you can type:

`display filter ip.dst = 1.2.3.4`

Finally, if you want to see all current UDP or TCP packets, you can type `udp` or `tcp` in the Filter bar or in the CLI.

For more information on display filters, see the wireshark-filter(4) manual page. For more information on capture filter syntax, see the pcap-filter(7) manual page.

By following these steps, you should be able to update Wireshark and start capturing network packets on your Ubuntu terminal.
