Traditionally, WLAN is the supplement and extension of wired LAN. It has the advantages of flexibility, mobility and low investment cost. It is favored by home network users, small and medium office users, enterprise users and telecom operators. One of the fastest growing industries in the entire data communication field.
A local area network is generally built by a unit, and its management and use are controlled within the unit or department, and the owner of the network is responsible for management and maintenance. Local area networks generally focus on the processing of shared information, usually without a central host system, but with some shared external devices.
LAN has the following three advantages:
1. The information transmission rate is high, the delay is small, and the bit error rate is low. The transmission rate of the LAN is generally 10-100Mbit/s, and the transmission delay is generally several milliseconds to tens of milliseconds. Because the local area network generally uses wired transmission media to transmit information, and there are dedicated communication lines between the two sites, the bit error rate is low, only 10?12 to 10?8.
2. The geographic coverage is relatively small. The local area network is mainly used for the internal networking of the unit, and the scope is within an office building or a concentrated building group, generally within a few kilometers.
3. Easy to install, maintain and expand. Due to the small scope of LAN applications, the application software running on the network mainly serves the unit. Therefore, whether it is a hardware system or a software system, the installation cost of the network is low, the cycle is short, and maintenance and expansion are very convenient.
How to access SVN in LAN without LAN tools?
The editor's previous work often involved post-maintenance of the client's server. Usually, the client's database was backed up to a copy on his own server. When doing maintenance, after modifying the program on his own server, the program was copied to the client's Republished on the server. The disadvantage of doing this is that the data of the own server and the server of the customer cannot be synchronized at the same time. If there are multiple customer systems that need to be maintained at the same time, it is very inconvenient.
To solve this problem, it is necessary to find a method to publish the LAN SVN server to the external network, so that the customer's server can directly load the SVN code of the own server. After doing a lot of research and comparison, the editor found that using Jinwanwei's fast analysis intranet penetration function can achieve external network access to SVN. The server is in the company's intranet and has no public network IP and no router management authority. Quick analysis can solve these problems, and it can be published without copying again, saving time and effort. Let's see the detailed steps.
1. Register for a quick analysis account
Log in to the official website of Jinwanwei Quick Analysis: http://www.kuaijiexi.com/ to register an account. (You can also download the client on the official website first, and register an account on the client)
2. Download and install the quick analysis client
After downloading and installing the quick analysis client, enter the registered account password and log in.
Click "Add Mapping" in the upper left corner of the client
3. Fill in the mapping information
Mapping name: custom, easy to distinguish and mark.
Public port type: Refers to the port used for external network access, which is selected according to the application requirements of your own scenario.
Intranet address: Intranet access fixed address. It can be a fixed intranet IP or a computer name. If the mapping is used locally on the server, it is recommended to fill in the 127.0.0.1 format.
Application port: subject to actual conditions, do not fill in randomly.
Click OK, and an external network access address will be generated.
4. Connection detection
So far, the port mapping of the server has been completed. Computers on the external network can access the generated external network access address through a browser, or download the SVN client to access, and then they can access the SVN in the LAN.
Quick Resolution is one of the earliest intranet penetration service providers in China with tens of millions of users. Intranet penetration service can also be realized without public network IP, and file transfer, upload and other operations can be performed within the company's LAN.
