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

1. Overview of Intranet Security After the 21st century, with the rapid increase of information technology in China, the Intranet Information security has received more and more attention. In just a few years, Intranet security products and vendors have emerged. However, it is worrying that although many products and vendors provide services with the concept of

Intranet SecurityThe problem has been hard to solve since the beginning. The most important cause is that LAN technology has been adopting an open and shared resource model since the first day of commercial use. While pursuing high convenience, security will inevitably be affected. According to various published survey data, even in the most optimistic circumstances, the loss caused by Intranet security pro

Intranet SecurityFor enterprises, the problem should start from four levels and take into account the internal network security of the enterprise comprehensively. In terms of it o M, the security of user behavior should be determined. Finally, when users pass layer-by-layer security checks, in addition, enterprises also need to check the security of their infrastructure configurations to ensure boarding security. In response to the above problems, ac

In the TCP/IP protocol, three IP address zones are reserved for private addresses with the following address ranges:10.0.0.0/8:10.0.0.0~10.255.255.255172.16.0.0/12:172.16.0.0~172.31.255.255192.168.0.0/16:192.168.0.0~192.168.255.255So, go directly to the code:Public Static BooleanInternalip(String IP) {byte[]Addr= Ipaddressutil.textToNumericFormatV4(IP);returnInternalip(Addr);}Public Static BooleanInternalip(byte[] addr) {Final byteB0= addr[0];Final byteB1= addr[1]; //10.X.X.X/8 Final bytes

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
