Final Project X-Messenger servers Final project X-Messenger servers X-Messenger is an instant messaging tool launched by xuanyuan high-end it training center. It supports text chat, file transmission, friend management, and other instant messaging functions. As one of the final projects of the Linux C ++ series courses, the objective is to train students in C ++ basics, C ++ standard libraries

Preface: After a brief introduction to the network layer protocol and HTTP protocol in the previous topic, I believe that you have a general understanding of the protocols in the network. This topic will define a Web server for the HTTP protocol, you can view the desired webpage by entering a URL in the browser. In this process, the browser is only a client.Program) Send user requests to the server through the HTTP protocol. The server receives the sent HTTP requests and then processes and res

How does a user's request interact with the Web server (apache,nginx,iis,light) and the backend's dynamic language (such as PHP) and return the results to the user? This article discusses the personal point of view, may be wrong, welcome to shoot bricks, study together. I. First clarify several concepts for follow-up instructions CGI: (Common Gateway Interface) an intermediate layer in which HTTP servers interact with back-end programs such as PHP. W

Connection between WinNT, Linux, Unix, and other servers-Linux Enterprise Application-Linux server application information. For details, refer to the following section. Since Novell NetWare uses the IPX/SPX protocol, access to NetWare resources in Windows NT is converted through the Protocol. The Windows NT Server provides the GSNW gateway service, allowing Dos/W

Web|web Service |web Server | security | Attack the second type of security issue we want to discuss involves private data under the server's Common directory. Many web space providers provide only "web space", which maps the root of a user's FTP directory to the root of a Web server. That is, users can access the server directory "/home/www/servers/www.customer.com/" via FTP, while anyone can access it through the URL "http://www.customer.com/". FTP-

With the expansion of Linux enterprise applications, there are a large number of network servers using the Linux operating system. Linux server security can be more and more attention, here according to the depth of the attack on the Linux server in the Level form, and propose different solutions. The definition of a Linux server attack is that an attack is an unauthorized behavior designed to hinder, damage, weaken, and compromise the security of a L

Introduction to HTTP protocol Hypertext Transfer Protocol (HTTP) is located in the TCP/IP protocol application layer, is the most well-known protocol, but also one of the most core protocols in the interconnection network, the same, HTTP is based on C/s or B + + model implementation. In fact, the browsers we use, such as Netscape or IE, are the clients that implement the HTTP protocol, and some common Web server software such as Apache, IIS, and ipla

Let's introduce Rsync and inotify.1. rsyncCompared with the traditional methods of CP and Tar Backup, rsync has the advantages of high security, fast backup, support of incremental backup, and so on, rsync can solve the requirement of low-real-time data backup, such as regular backup file server data to remote server, regular data mirroring for local disk, etc.With the expansion of application system scale, the security and reliability of data also pu

disk to the OS cache. Because this copy is done in the kernel, sendfile () is more effective than combining read () and write () and turning off the discard buffer (more on sendfile) Tcp_nopush tells Nginx to send all headers in a packet, not one after the other. Tcp_nodelay told Nginx not to cache data, but a paragraph of the send-when the need to send data in time, you should set this property to the application, so send a small piece of data inf

Tips for optimizing Nginx servers This article mainly introduces some tips for optimizing the Nginx server, including the configuration suggestions for the HTTP module and the Events module. For more information, see Most Nginx installation guides tell you the following basic knowledge-install through apt-get and modify the configurations here or there. Well, you already have a Web server! In addition, in most cases, a regular nginx installation can w

Servers constitute the most basic elements in the network infrastructure and are also the most critical part of network security. Although Unix servers are well known for their security and reliability, they do not mean they are impeccable. In addition, the security of UNIX servers affects or determines the security of the basic network structure. In general, we

When Server Load balancer is used to deploy two site servers, there are several problems and their solutions. 1. when you copy the published site file to the IIS Directory, prepare IIS support for the Framework, and visit the website, the Service unavailable word always appears, depressing .... search and find the solution:Open the attributes of the IIS websites folder, and go to the service tab. Select Run WWW Service in IIS 5.0 Isolation Mode.Fo

A VPS can be divided into multiple virtual hosts, so that you can do a number of sites (how much can be placed by the server assigned to this VPS how large configuration). This is the author of the interface of the VPS, installed is the WIN2003 system, the server is similar, is not very common computer system like? NBSP; web Hosting : Virtual hosting is a network server on the partition of a certain amount of disk space for users to place

application layer is quite broad, what's even more surprising is that Samba Server can also be used as a WINS Server. If it is used with DHCP Server, it can manage large NT/2000 domains. samba should be mainly used in networks where Windows and Linux systems coexist. If a network environment is a Linux or Unix system, it is better to use NFS if Samba is not necessary; Samba has two servers: smb and nmb.

For SQL Server2000, open the SQL Server client ready to connect, and when the list of servers is pulled out, all SQL Server servers are listed for the entire LAN. So I found out that this UDP packet was broadcast from 1434 Port (192.168.0.255) on my own Machine (192.168.0.1), and then the SQL Server server in the entire LAN started responding to this UDP packet, My client can get all of the server informati
