The ports and protocols used by the Samba service:1) Port 137 (UDP)-NetBIOS name service; NMBD2) port 138 (UDP)-NetBIOS Datagram Service 3) port 139 (TCP)-File and print sharing, SMBD (SMB (Server Message Block) protocol, mainly used on LAN, file sharing protocol) 4) port 3 (TCP)-for LDAP (Active Directory Mode) 5) port 445 (TCP)-NetBIOS service uses this port in WinDOS 2000 and later versions (Common Internet File System , CIFS, which is the SMB prot

the transport layer, whether it is a WEB server or browser client, you have to change the big, the movement is too large)2. Use a new protocol alone to wrap up the HTTP protocol(The so-called "http over SSL" is actually a layer of SSL encapsulation outside of the original HTTP data.) HTTP protocol of the original GET, POST and other mechanisms, basically intact)For example: If the original HTTP is a plastic pipe, easy to be punctured, then the new de

Introduction to TCP/IP and other network protocols 1. TCP/IP is a communication protocol for the Internet. Computer Communication Protocols are descriptions of the rules that computers must comply with in order to communicate with each other. TCP/IP refers to the Transmission Control Protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol ). TCP/IP defines how electronic devices (such as

less reliable.In order to improve the reliability of the network, the TCP protocol was born, did not send a packet is required to confirm, if a packet is lost, it is not confirmed, the sender know it is necessary to re-send the packetBoth TCP packets and UDP packets are embedded in the data portion of the IP packet, and the TCP packet has no length limit. Theoretical no limited, in general, the lenght of TCP is no longer than the Lenght of IP package to ensure Singal TCP package don ' t need to

mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data. Regarding the relationship between TCP/IP and HTTP protocol, the network has a relatively easy to understand: "When we transmit data, we can only use the (Transport Layer) TCP/IP protocol, but in that case, if there is no application layer, it will not be able to identify the data content, if you want to make the transmitted data meaningful, You must use th

For network security, this is a more complex structure and engineering. Many factors can affect our network environment. In the network, we define various network security protocols for effective protection. Next we will compare and analyze different protocols. SSL and IPSec (1) SSL protects the security of data transmitted on the transport layer. In addition, IPSec also protects the security of data packet

The foundation of the network is the establishment and application of many computer network protocols. So how can we understand this concept? The following describes the overview of computer network communication protocols. Network Communication Protocol (Network Communication Protocol )) it is a set of definitions of the Information Format for communication between computers and the transfer content that c

Cp http udp: All are communication protocols, that is, the rules observed during communication. Only when both parties "speak" according to this rule can the other party understand or serve it. Relationship Between tcp http and UDP: TCP/IP is a protocol group, which can be divided into four layers: network interface layer, network layer, transmission layer and application layer.The IP protocol, ICMP protocol, ARP protocol, RARP protocol, and BOO

Multicast routing is a good technology. It broadcasts data over the Internet. Unlike broadcast, due to broadcast storms, the router prohibits cross-route transmission of broadcast data. Multicast solves this problem. Currently, m$ software such as NetMeeting and WMS are widely used in multicast. Here we will discuss how to build your Linux into a multicast router.(Generally, gateways and routers do not support multicast data packets ). 1. Transmission Protocol Network Cameras provide many IP-b

handshake protocol. SSL is developed by Netscape to protect Web communication. The current version is 3.0. The latest version of TLS 1.0 is a new protocol developed by IETF (engineering task group). It is based on the SSL 3.0 protocol specification and is a later version of SSL 3.0. The difference between the two is very small. it can be understood as SSL 3.1, which is written into RFC.SSL (Secure Socket Layer) is developed by Netscape to ensure the

How should we understand network communication protocols? Can we fully master the increasingly complex network structures? We need to rely on network communication protocols for learning and understanding. Network Communication Protocol (Network Communication Protocol )) it is a set of definitions of the Information Format for communication between computers and the transfer content that can be accepted by

The HTTP protocol defines eight methods or "actions" to indicate different ways to manipulate the resources specified by the Request-uri.The details are as follows:OPTIONS: Returns the HTTP request method that the server supports for a specific resource. You can also test the functionality of your server with a request to send a ' * ' to the Web server.HEAD: Ask the server for a response that is consistent with the GET request, except that the respons

protocol is Neighbor Discovery (ND), which is developed for IPv6. To be available in VPC, the Linux kernel supports other Neighbor protocols, such: the neighbor protocol used by DECnet. What is the neighbor protocol proxy? If a host intercepts the traffic sent to another host and processes the traffic in place of the latter, the host is a proxy. The proxy server of the neighbor protocol is a host that responds to the solication request for a request

Description of some network protocols DICT: a dictionary server protocol. Dict servers and clients use TCP port 2628 FILE: Mainly used to access files on local computers, just like opening a file in Windows Explorer. FTP: (File Transfer Protocol, FTP) is the Protocol for transferring files from two computers on the TCP/IP network. FTP is one of the earliest protocols used on the TCP/IP network and the INTER

form of a custom uri-scheme, webview triggers a unsupportedurischemeidentified event, indicating that WebView does not recognize this protocol and whether to deal with it depends on you.The webview of the UWP can only handle protocols such as HTTP, HTTPS, Ms-appx-web, and Ms-local-stream, and will trigger unsupportedurischemeidentified events for other protocols

The reason why routers can run normally is the result of a lot of different protocols working together, why can the protocols coexist without affecting each other? This is what the following is about, the concepts of routing protocols running. VRF: One of the security initiatives of routing protocols is routing isolat

SRTP srtcp Reference rfc3711 Secure real-time transmission protocol (secure real-time transport protocol or SRTP) is a protocol defined based on the real-time transport protocol or RTP, the aim is to provide encryption, message authentication, integrity assurance and replay protection for data in real-time transmission protocols in unicast and m

TCP provides reliable data transmission in IP environment, and it provides services including data transfer, reliability, effective flow control, full duplex operation and multiplexing.
