Whether you are a server administrator, a network administrator, or a VMware administrator, you use a protocol analyzer, also known as a data packet analyzer or a "sniffer", as a common tool for analyzing network problems. These software applications can analyze network traffic in real time, allowing you to view packets that pass through the

Linux Virtual Machine simulated configuration Network Routing environment-lite version, linux Virtual MachineNetwork Routing must be configured at home or in the company, so it is very important. Today, I will give you a small experiment on configuring network routing, for your reference only. 1. First, let's briefly i

Gigabit and two HBA ports as an example, after the above 10 Gigabit, virtualization, and FCoE combination, you only need a pair of Redundant Dual-active 10-Gigabit CNA (Converged Network Adapter) NICs to complete all the original functions. In addition, the storage I/O performance is improved by 10%, and the CPU usage is reduced by 8%, wiring management complexity is reduced by 80%, interface card cost is reduced by 40%, access switch cost is only 1/

VLAN (Virtual LAN) technology is an important technical measure to ensure the safe and stable operation of large networks. with the active participation of many vendors and the widespread acceptance of end users, it has been widely used in actual network construction. The reason why VLAN technology is attractive is that it has enhanced its network management func

the Virtual Private Network VPN function, and advanced security features, currently priced at 1850 yuan, is a top-level enterprise wireless hotspot application solution.Linksys VPN wireless router WRV54G is an avant-garde, modern, and can be placed upright, like a radio. It is a wireless access point, fully compatible with 802.11b/G networks, and has four built-in full-duplex M switches. Finally, the route

directly connected to the IP network, they do not need the first PPP dial-up connection. They can directly establish a virtual path with the PPTP server. The biggest advantage of PPTP is Microsoft's support. Another advantage is its support of traffic control, which ensures no congestion between the client and the server and improves communication performance, minimize packet loss and resend. PPTP gives th

partition function and can be divided into multiple virtual bridges. When Partitioning in this way, the broadcast information will be restricted to those ports with the virtual bridge and the corresponding VLAN, rather than being sent to all ports. Limiting broadcast in a VLAN does not prevent the system in a VLAN from accessing the system connected to the same bridge and belongs to a different VLAN. Howev

Data center network administrators now need to "reconnect" physical resources and virtualization workloads to learn how they are used and how they are managed. From the perspective of management and monitoring, this requirement for connecting physical resources and virtual workloads will drive a part of the entire virtualization industry.
