intranet connections

What is persistent connection? In fact, persistent connections are relative to common short connections, that is, to maintain the connection between the client and the server for a long time. The common short connection procedure is as follows: Connection-data transmission-close connection; The persistent connection is usually: Connection-data transmission-keep connection... -Close connection; T

Label: The current summary of the statement, in view of the data connection is very useful, after writing the program while testing the code side to see the release of database connections to help optimize the analysis of a robust system program. 1.SQL code1.select Count (*) from v$processSelect COUNT (*) from v$process--current number of database connections 2.SQL code1.s

Label:data queries involving two of tables in a database are typically implemented using a connection method. Connections are divided into inner and outer connections. Internal connection: The connection result contains only the rows that meet the join criteria, and the two tables participating in the connection should meet the join criteria. External connection: The result of the join cont

, and the financial report system could not handle statistics, all services were interrupted for about five hours, resulting in loss of material and reputation of the company. The final reason is that our company only has a simple access firewall at the internet exit. The company's website and email server are located in the external interface area of the firewall and use public IP addresses. Because the website is attacked and implanted with ARP spoofing Trojans, all office and business PC gate

Rogue DHCP server Intranet attack test Intranet penetration is usually Based on ARP attacks, but ARP attacks are too costly to the Intranet and are easy to detect. Today we are talking about DHCP-based attacks. DHCP-based attacks are easy to understand. First, hackers use their own hosts to forge a DHCP server by forging a Mac address and exhausting the IP addres

Web intranet penetration implementation based on HTTP/2 HTTP/2 introduces the binary frame separation layer to split requests and responses in HTTP/1.1 into finer-grained frames ), in this way, priority, traffic control, and Server Push are implemented. HTTP/2 can open multiple streams on a single TCP connection to achieve multiplexing; HTTP/2 uses a static dictionary, a dynamic dictionary, and a Heman encoding to compress the request/response header

Today, colleagues have a demand, hope that the Web server in the Nodejs of the corresponding site can support intranet access, and later found to modify the hostname attribute in Express for their own intranet IP can be. But the problem is that our machines are automatically acquired intranet IP, then this time the death of the hostname will not be able to use th

User features of Intranet Security Cases There are a large number of design documents, survey data and other value information that need to be protected with emphasis. In particular, the survey data has been included in the scope of national defense strategic information and needs to be protected with emphasis; The design documents submitted for the customer are relatively large, and the editing software of each professional department of the Design I

An SSRF vulnerability in zhihu main site can detect the Intranet The https://www.zhihu.com/question/38548957/answer/77482000 was found to answer this question.It is really a bit interesting. I answered the question of the subject using actual vulnerabilities. Is intranet security really not heavy? With this vulnerability, I can detect and access the intranet of

In our ongoing build, there is an error alert in the construction of the project. Or the communication between the developers, progress reporting of the transaction, is inseparable from a communication tool. That's The mail. It is certainly not the best option for us to assume the use of third-party mail platforms in our project development. Because the third-party mail needs to support the external network, but the external network is not particularly reliable, if there is a problem with the ne

Whether php can obtain the user's intranet ip address from the internet. if the user connects to the Internet through a router or other devices, php can be used to obtain the intranet ip address of the user, that is, 198. xxx. xxx. ip address like xxx. This refers to access from Internet users, rather than obtaining the intranet where the server host is located!

In our continuous construction, errors or communication and progress reporting between developers are all inseparable from a communication tool, that is, emails. If a third-party email platform is used in our project development, this is definitely not the best choice, because third-party emails require Internet support, but the Internet is not particularly reliable, if there is a problem with the Internet connection, it will not be necessary to delay our construction period. In addition, many p

Today colleagues have a demand, hope that the Web server in the Nodejs of the corresponding site can support intranet access, and later found that the change in express hostname properties for their own intranet IP can be.
