How To Install dsniff on CentOS 8

dsniff is Tools for network auditing and penetration testing

Introduction

In this tutorial we learn how to install dsniff on CentOS 8.

What is dsniff

A collection of tools for network auditing and penetration testing. Dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf and webspy allow to passively monitor a network for interesting data (passwords, e-mail, files). Arpspoof, dnsspoof and macof facilitate the interception of network traffic normally unavailable to an attacker (e.g, due to layer-2 switching). Sshmitm and webmitm implement active monkey-in-the-middle attacks against redirected SSH and HTTPS sessions by exploiting weak bindings in ad-hoc PKI.

We can use yum or dnf to install dsniff on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install dsniff.

Install dsniff on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:
