Open the Command Prompt window and set the working folder to C: Program FilesSupport Tools.3. Run the following command to verify that an existing IPSec Policy is specified for the computer:Netdiag/test: ipsecIf no policy is specified, you will receive the following message:IP Security test ......: Passed IPSec policy service is active, but

Find the service name with the specified port and protocol if you want to find a network service, it is best to know which port the service is running on TCP or UDP protocol. If you know the port that the Network service uses, you can call the Getservbyport () function in the socket library to get the name of the service.Technical Point decomposition:1, define the Find_service_name () function, note the code indentation in the function2, Getservbyport (Port,port_type), through the port lookup se

Protocols and ports used by Windows Server Failover ClusterThe Windows server Cluster service, the Cluster service, is used to control server cluster operations and to manage the internal flat file database of the cluster. A cluster is a collection of standalone servers that are combined and serve as a separate entity for external service. The cluster that the user sees is a separate system. If a node fails

In the previous post, "Installing, Deploying DPM 2010 Server," We went to work with you on how to complete the installation of DPM, posting today, mainly to chat with you about the DPM 2010 installation process, which ports we need to open, here, We use Group Policy to introduce how to open ports for DPM, and, of course, you can have the policy of opening ports f

Redis Research (13)-security and communication protocols, redis research communication protocols I. Security Salvatore Sanfilippo, author of Redis, once published the Redis declaration, which mentions Redis to be concise and beautiful. Redis does not do much work at the security level.1. trusted environmentThe Redis security design is based on the premise that "Redis runs in a trusted environment". During t

Open source is already widely used in today's software industry, but does open source mean that users can do whatever they want to do with open source code? The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensation. There are many open-source

The usage of softswitch protocol is described in four special protocols. Next we will give a brief introduction to several main Softswitch protocols, such as H.248/MEGACO, Media Gateway Control Protocol MGCP), and Session Initiation Protocol SIP. Main protocols used by Softswitch The softswitch system involves many Softswitch

The routing information protocol, that is, the RIP Protocol. This protocol is one of the earliest in the routing protocol family. It plays a fundamental role in the development of some subsequent protocols. So let's compare several protocols. The Routing Information Protocol (Routing Information Protocol) is an ancient Routing Information Protocol based on the distance vector algorithm. It selects the optim

A Preliminary Study on WCF-17: the equivalence of WCF data protocols, a preliminary study on wcf-17 protocolsData contract equivalenceFeatures If the client successfully sends data of a certain type to the service or the service successfully sends the data to the client, the receiving end does not necessarily have to send data of this type. The only requirement is that the two types of data protocols sho

How to quickly learn about network protocols and network protocolsI. What is the network protocol? Generally speaking, network protocols are a bridge between networks for communication and communication. Only computers with the same network protocol can communicate and communicate information. This is like the various languages used for communication between people. Only when the same language is used CAN c

Network transmission protocol or communication protocol for shortProtocol) refers to the common language for computer communication. Currently, the most popular computer communication is network communication. Therefore, the "Transfer Protocol" generally refers to the transmission protocol for computer communication, such as TCP/IP and NetBEUI. However, the transfer protocol also exists in other computer forms of communication, such as communication between objects in object-oriented programming

OC-Concepts and usage of protocols, oc-concepts of protocols In the previous article, we introduced the class extension in OC: Extend. The protocol in OC is equivalent to the interface (abstract class) in Java, but the name in OC is more vivid, because when we are learning interfaces in Java, it can be seen that the interface is equivalent to a contract (Protocol), marking its implementation class. Of cour

Escape characters in communication protocols and escape characters in communication protocolsEscape characters in communication protocolsPurpose: make the communication content more secure and reliable in the communication protocol.For example: if you need to customize a communication protocol, the most basic thing you need is a frame header and frame tail flag, only the recipient of the communication knows when the communication starts and ends.

DHCP can automatically assign an IP address to each computer in the LAN, complete the TCP/IP protocol configuration for each computer, including the IP address, subnet mask, gateway, and DNS server. In this way, the Administrator does not need to manually configure the TCP/IP protocol for each computer in a LAN, especiall

protocol used by this file transfer process is called the FTP protocol. File transfer in FTP establishes two TCP connections, respectively, to the control connection to use when sending a transmission request and to the data connection that is used when the data is actually transferred. Remote login (telnet and SSH) is a feature that logs on to a remote computer and enables programs on that computer to run. Remote logins commonly used telnet and ssh two kinds of
