The operating system’s kernel provides access to virtual machines as well as packets being sent and received.Ī mirror port on a switch is eth0, which is also the port that is linked to a WiFi network. A virtual interface is a non-physical port that is present in the same way that a physical port is it can be either veth, docker, tun, or tap. If you sniff br0, you’ll get packets from all of the physical interfaces connected to it at once. This program is unquestionably possible, but it will only reveal internal traffic – no data from other computers. A loopback interface is any interface that begins with lo (for example, lo0). How do you know which interface to look for when sniffing on a computer? The command line allows you to see a list of all interfaces available. This article will explore the fundamentals of Linux packet interfaces and explain how they work within the overall Linux network architecture. The interface packets use in Linux is a critical element of this system, and understanding how it works is essential for any network administrator. A key component of Linux is its packet-based networking layer, which provides the foundation for data transmission and communication between computers. It is used in a variety of applications, from home computers to large-scale enterprise networks. The Linux operating system is one of the most popular and powerful operating systems available today.
