Mirroring, technology, typically refers to the process of replicating or duplicating the display of one device onto another. For example, screen mirroring allows you to display the screen of a smartphone, tablet, or computer onto a larger screen like a TV or projector. In network or server contexts, mirroring involves duplicating network traffic from one … Read more
Port forwarding and VPN (Virtual Private Network) serve different purposes in networking but can sometimes complement each other depending on the specific use case. Port forwarding involves redirecting incoming network traffic from one port on a router or firewall to another port on a different device or server within a private network. It is commonly … Read more
STP (Spanning Tree Protocol) in routing and switching is a network protocol used to prevent loops in Ethernet networks where multiple paths between switches could cause broadcast storms and network instability. STP operates by dynamically selecting a single “root bridge” among interconnected switches and then disabling redundant paths to ensure a loop-free topology. It accomplishes … Read more
Port forwarding is used to redirect incoming network traffic from one port on a router or firewall to another port on a different device or server within a private network. It enables external users or devices to access specific services or applications hosted on devices behind the router or firewall. Common applications include hosting websites, … Read more
VLAN tagging offers several benefits in network management and operation. It allows network administrators to logically segment a physical network into multiple virtual LANs (VLANs), each representing distinct broadcast domains. By assigning VLAN tags to Ethernet frames, switches can identify and forward traffic based on VLAN membership, regardless of the physical port the traffic enters. … Read more
The functions of MAC (Media Access Control) encompass several key roles in computer networking and communication protocols. Firstly, MAC addresses uniquely identify devices within a network, serving as their physical address. This allows devices to communicate with each other over Ethernet or Wi-Fi networks, ensuring data packets are correctly routed to their intended destinations based … Read more
VLAN tagging is essential for segmenting and organizing network traffic within a single physical network infrastructure. It allows network administrators to logically group devices into separate broadcast domains, or VLANs, regardless of their physical location on the network. By assigning VLAN tags to network frames, switches can direct traffic more efficiently, improving network performance and … Read more
Wireshark captures packets by monitoring network interfaces in promiscuous mode, allowing it to intercept and record all packets passing through the interface. When Wireshark is running, it captures packets by listening to the network traffic on the specified interface or interfaces, capturing both incoming and outgoing packets for analysis. To capture HTTP packets specifically in … Read more
Wireshark is primarily used as a network protocol analyzer, allowing users to capture and inspect the data packets traveling over a computer network. Its core functionality includes capturing network traffic in real-time or from stored files, analyzing packet contents at various layers of the OSI model, and providing detailed insights into network protocols and communications. … Read more
Netstat is a command-line utility used to display network statistics on Unix-like operating systems and Windows. It provides information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. Netstat allows users to monitor active network connections, view open ports, and track network traffic in real-time. The netstat statistics command, often used with … Read more
