How To Install Wireshark on Debian 11

This guide intends to teach you to Install Wireshark on Debian 11.

Wireshark is a free open-source tool that analyzes network traffic in real-time for Windows, Mac, Unix, and Linux systems. It captures data packets passing through a network interface (such as Ethernet, LAN, or SDRs) and translates that data into valuable information for IT professionals and cybersecurity teams.

Wireshark is a type of packet sniffer (also known as a network protocol analyzer, protocol analyzer, and network analyzer). Packet sniffers intercept network traffic to understand the activity being processed and harvest useful insights.

Steps To Install Wireshark on Debian 11

To install Wireshark, you need to log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide on Initial Server Setup with Debian 11.

Install Wireshark Network Analyzer on Debian 11

The Wireshark package is available in the default Debian repository.

First, update your local package index with the command below:

sudo apt update

Now use the following command to install Wireshark:

sudo apt install wireshark -y

The system by default only lets users with sudo access capture network data, if you also want the non-root users to use the Wireshark to analyze the network then select the Yes option otherwise let the No be selected and simply press the Enter key.

When your installation is complete, verify it by checking the Wireshark version:

apt policy wireshark

  -f <capture filter>      packet filter in libpcap filter syntax
  -s <snaplen>, --snapshot-length <snaplen>
                           packet snapshot length (def: appropriate maximum)
  -p, --no-promiscuous-mode
                           don't capture in promiscuous mode
  -I, --monitor-mode       capture in monitor mode, if available
  -B <buffer size>, --buffer-size <buffer size>
                           size of kernel buffer (def: 2MB)
  -y <link type>, --linktype <link type>
                           link layer type (def: first appropriate)
  --time-stamp-type <type> timestamp method for interface
  -D, --list-interfaces    print list of interfaces and exit
  -L, --list-data-link-types
                           print list of link-layer types of iface and exit
  --list-time-stamp-types  print list of timestamp types for iface and exit

Capture stop conditions:
  -c <packet count>        stop after n packets (def: infinite)
....

If it doesn’t work, install it by using the command below:
