How to access the Web site on one of the machines in the LAN from the external network? Just set the mappings on the router? I was connected to the extranet via the LAN. I now have a new website in my local through Dreamweaver (station name: www.abc.com) How can I get access from the extranet? (That is, you can access it by typing www.abc.com on an external W

Recently, the company has been developing remote video and remote monitoring projects. We just have time to summarize them, I don't know much about it, just follow the feeling; Query a lot of information, all scattered, some good information on foreign websites, Many of them are implemented using C and C ++. I have limited technical skills and can only use C !! In the early stage of winform testing, it was just a simple step and a simple test. After the core functions were initially p

tools may be different. (For example, Wireshark may not populate the data segment, while sniffer may capture the data segment) Addressing Ethernet uses a 6-byte physical address provided by the NIC, which is usually expressed in hexadecimal notation. Example: 06: 01: 02: 01: 2C: 4B The Unicast address, multicast address, and broadcast address source address are always one Unicast address (because the frame only comes from one site). The destination address can be a unicast address, it can also

first of all, you have to break the net .

On October 11, October 1, the national day was over. I got up at 6.3 in the morning and got to work at half past seven. The weather was very good. But the road was cold and clear. It is estimated that everyone is sleeping ..First, plug in the network cable and open the computer. ah, oh .. cannot access the Internet .. test .. ah, oh .. still cannot access the Internet .. think about the reason .. nothing bad recently .. no LJ website .. and yesterday

Ubuntu is a great Linux operating system, but how to connect to the Internet with Ubuntu is a big hurdle for new users who just installed it. Now record the process of surfing the Internet under Ubuntu.★clientAfter extracting the client, copy it to the desktop of your Ubuntu system (you can put it in other places, just think it's easier to put it on the desktop), open the directory and look inside the file.★ Change File permissionsOpen terminal, switch to this folder below,Then switch your users

The steps are as follows: First, the reason analysis:Microsoft has added a new security mechanism to Windows 10, and the lack of access to the password is thus being judged unsafe by the system. Second, the solution:method One:You can set up an administrator user with a password on a shared computer, or add a password to a single previous account.Method Two:If you feel the loss of the password is too cumbersome, you can do the following:1, press the WIN+R input regedit return to open Registry Ed

I mainly use QQ and MSN for online chat. Other skype and others can be used in Ubuntu. I will not describe it here. 1. The most frequently used chat software for MSN chat in Ubuntu may be GAIM, but now it has been changed to Pidgin. Note: Gaim has been renamed Pidgin. After more than a year of beta, the official version of Pidgin2.0.0 was finally released. To dow

Using Linux to implement TCP-mode-based network chat programsThe two main components are: Server and client. The server program is primarily responsible for listening to messages sent by the client. The client needs to log on to the server side in order to achieve normal chat functionality. The program uses processes and shared memory to send message

Recently, in Socket network socket programming, the client and server are always unable to respond in synchronous and asynchronous communication, but the communication chat function has been completed in TCP programming, the following is a brief description of the source code and detailed comments of the TCP chat I recently learned. TCP is a transport layer proto

Before I begin, I'd like to describe what this so-called communication program is all about. The communication program is similar to a weak version of QQ, login needs to register, after successful login, you can achieve instant communication, group chat, private chat, but also can be transmitted documents. Let's get to the last picture Server side: Client Login: Client main interface: The so-called real-ti

This article describes a network service program similar to the chat server function in the Boost.asio sample code, including the Muduo implementation of the client and service side. The main purpose of this example is to describe how to handle subcontracting and to initially involve Muduo multithreaded functionality.

In the recent study of the Netty framework, the use of learning materials is Li Linfeng's "Netty Authority Guide." There are few books on Netty in China, and this book is a good entry resource. I always feel that learning a new framework, in addition to the source code of the research framework, should also use the framework to develop a practical small application. To this end, I choose Netty as a communication framework, the development of a simulation QQ
