Wireshark is a popular network protocol analyzer that can be used to capture and analyze network packets. In this tutorial, we will learn how to install Wireshark on OpenBSD.
Before installing Wireshark on OpenBSD, you must have access to an OpenBSD system with superuser privileges.
The first step is to update the OpenBSD package repository by running the following command:
pkg_add -u
This will update the package repository to the latest version.
To install Wireshark, run the following command:
pkg_add wireshark
This will download and install the latest version of Wireshark on your OpenBSD system.
By default, Wireshark will not run as a regular user. Therefore, you need to give the user permission to capture packets.
To configure Wireshark to run as a regular user, run the following command:
sudo chown root:wireshark /usr/local/bin/dumpcap
sudo chmod 4755 /usr/local/bin/dumpcap
This will change the ownership of the dumpcap binary to root:wireshark and set the SUID bit on it. This will allow regular users to capture packets.
To launch Wireshark, run the following command:
wireshark
This will launch Wireshark GUI. You can use the GUI to capture and analyze network traffic.
To capture packets, select the interface you want to capture packets from and click on the "Start" button. Wireshark will start capturing packets on the selected interface.
In this tutorial, we learned how to install Wireshark on OpenBSD. We also learned how to configure Wireshark to run as a regular user and how to capture packets using Wireshark GUI.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
