On a Linux server or on a Windows server, You can use this command to create a Web service that can be accessed quickly in the intranet, as long as you install Python. In the directory where you want to build the Web service, use the python3.x built-in method:Python-m Http.server 80008000 is the port number of the link, so that the local in the browser can access the directory through http://localhost:8000, and the LAN, such as other computers, can b
Problem Description:
1, the PIX placed in a fixed IP environment (external network for fixed IP), and set the correct ACL allow ICMP release, this case intranet can be normal Internet access can also ping the extranet.
2, and then put the PIX in the ADSL environment (with PIX to dial), ACL or before the same, PIX under the intranet computer can only surf the internet, can not ping the extranet.
Solution:
One, the internal LAN all use the private address on the network, under the normal circumstances, the internal computer in the direct use route external access, will because the computer uses is the Internet reservation address, but is filtered by the router, thus causes cannot access the Internet resources, The solution to this problem is to use the NAT address translation function provided by the routing operating system to convert the private address of I

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

Intranet Security Status Quo Analysis
The theory of Intranet security is relative to the traditional network security. In the traditional network security threat model, it is assumed that all the personnel and devices in the Intranet are secure and trusted, while the external network is insecure. Based on this assumption, Internet security solutions such as anti-
Most enterprises pay attention to improving the border security of enterprise networks, but do not mention their investment in this area, but the core intranet of most enterprise networks is still very fragile. Enterprises have also implemented corresponding protection measures for internal networks, such as installing network firewalls and intrusion detection software that may easily reach tens of thousands or even hundreds of thousands. They also ho
Almost all enterprises have paid more attention to network security. They have successively purchased firewalls and other devices to block security factors from the Internet. However, Intranet attacks and intrusions are still rampant. Facts have proved that the company's internal insecurity is far more terrible than the external harm.
