In 2020, researchers from the University of California and Tsinghua University found a new method to execute DNS cache poisoning attacks. Unfortunately, Linux, a very reliable OS, was the object of the DNS cache poisoning attack.
What is DNS cache poisoning?
A DNS cache poisoning (DNS spoofing) is a cyberattack that pollutes the cache on DNS resolver servers. This can cause the user to be redirected to the attacker’s server instead of the right one.
Are you a network administrator and want to gain insight into your network’s traffic? Then, the Traceroute command is here to your rescue! This simple yet powerful network diagnosis tool measures the latency of a connection to a given destination and provides a complete route path and associated latency. In this blog post, we’ll deeply dive into the Traceroute command and discuss how to use it, why to use it, and its benefits. So let’s get started and learn more about this invaluable networking tool!
What is the Traceroute command?
The Traceroute command is a powerful network diagnostic tool used to measure a connection’s latency to a given destination. When executed, this command sends a series of ICMP packets to the target, each with an increasing TTL value. As the responses are returned from each hop in the route to the destination, the Traceroute command can display the route path and associated latency. It can help network administrators find latency issues, track down errors, and understand the route path between two points. It is a valuable tool for troubleshooting and understanding networks.
