Securing remote server access is paramount for system administrators and developers. While it’s common practice to disable root login over SSH due to security concerns, there are scenarios where enabling it is necessary, such as when managing a remote server without a user account or for specific administrative tasks. This article guides you through enabling SSH root login on Ubuntu or Debian Linux servers or desktops, ensuring you can access your system with the necessary precautions.

An intrusion detection system (IDS) is an important security tool for system administrators. Its purpose is to notify us whenever it detects that a potential intrusion has occurred. When an attacker compromises a system, one of the first things they will usually do is attempt to change file permissions, attempt to escalate to the root user account, or start modifying system files. The IDS is configured to monitor for these changes and make us aware of them if they occur.

There are a plethora of tools available for the Raspberry Pi that system administrators can use to monitor network traffic. Newer Raspberry Pi models even come with a built in WiFi chip in addition to the traditional Ethernet port, giving us even more options for connecting to networks and monitoring traffic. Network monitoring can be useful for troubleshooting connectivity problems or identifying bottlenecks that are slowing down connections.

In this tutorial, we will go over various tools that can be used to monitor the network traffic on a Raspberry Pi. Along with default utilities on Raspberry Pi OS, additional packet sniffing and network analyzer tools such as Wireshark can be installed and used to gather information on network traffic. Let’s see how to use them.

The AVIF (AV1 Image File Format) is gaining popularity for its impressive compression capabilities without sacrificing image quality, making it a preferred choice for web developers and photographers alike.
