It is very convenient to develop MIS system on internet/intranet based on ASP technology, first of all, it borrows ADO technology and concept, and accesses database through ODBC, and achieves full flexibility and multi-platform, in addition, because of ASP using VBS and JS scripting language, It also ensures that most developers quickly enter the development process and reduce the learning process. However, because the ASP is based on the Internet/

Often the company's development environment will be arranged in the intranet, and then there will be a common server for everyone to develop, test, so often there will be SSH connection server, or local MySQL client connection server needs, I personally experienced the company often occurs ssh/ MySQL connection to the public server is very slow, because the SSH service and MySQL service by default will be at the time of the DNS reverse parsing process

From the first day of commercial use, LAN technology has been adopting an open and shared resource-based model. While pursuing high convenience, security will inevitably be affected, which is also the most important cause for the problem of Intranet security from the beginning. The fineness and depth of management often determine the final level of an Intranet security system. The solutions with higher leve

have been paying attention to network security for a long time generally believe that the changing trend of Enterprise Intranet security applications is actually a realistic portrayal of the rapid development of networks, today, enterprise users are very clear that they want to protect "information" rather than "Information Systems ". "Information" is everywhere in the network and constantly flowing in the network. Today, the transformation of custom

For the intranet computer is able to access through the router, because the router assigned an IP address, so that the computer has an identity, if the router can not be assigned to the computer IP situation, then we have no way to the Internet. First, the emergence of IP can not be assigned to the phenomenon is most of the client can not log in, can not get IP after login or very slow, in the operating system command prompt in the use of Network com
