The development environment is:Apache + python + django+ Eclipse (development environment)To achieve the purpose:On the Web page, add the upload file control. Then read the CSV file and parse the CSV file.Operation Steps:Django is the design pattern of MVC (model M, view V, controller C)1. Build your own model from Django's basic model.Add the following code to the myforms.py file, and the data for this model can be used in the HTML-displayed form data. fromDjangoImportForms fromDjango.views.dec
Use Nginx and iptables for access control (IP and MAC)
The previously configured server is public to the entire intranet. Besides indirectly accessing various services through nginx on port 80, you can also bypass nginx, it is wrong to directly access the corresponding service by using IP addresses and ports, so we need to make some restrictions, because only services are provided to specific people, And the lan ip address and MAC address are fixed, so you can use the White List directly, and re
the sample analyzed in this article, the main program creates a mail slot and acts as a mail slot server, while the code injected into each process serves as the client, they write the obtained credit card numbers into the mail slot and then transmit them directly to C2 through the mail slot.
At the beginning of program execution, the program calls the CreateMailslotA function with the mail slot name \ mailslot \ LogCC as the parameter.
If the mail slot fails to be created, the program will e
This task was taken over from Mr. Mi (the blog of MI Xinjiang. The purpose is to add restrictions to the examination system to prevent students from logging on outside of the examination in the LAN.
It sounds easy to filter IP addresses. The final result is to verify the IP address and decide whether to have the permission to access the examination system. But it is not easy to do well. Next, we will summarize the development process.

2) Dependency conflicts • Dependency conflicts do not need to be concerned. For example, two open-source third-party libraries reference different log4j versions, because the new version of log4j is compatible with the old version. We can thin

The previous example uses the/causes operation to list only the information of chainone, which is not filled with the import is the root cause of the rejection of addin. The/causes operation can be used in the normal and/verbose options.

In most cases, mefx can diagnose the root cause of a cascade fault. However, mefx will not be able to diag

Fix uipi Problems
Applications designed based on operating system behaviors before Windows Vista may want Windows messages to be freely transmitted between processes to complete some special work. When these applications run on Windows 7, because of the uipi mechanism, such message transmission is blocked, the application may

After ios9, you must add LSApplicationQueriesSchemes (whitelist) to the info. plist file to start the app you want to start. The URL of the app you want to launch is added to the whitelist

In the project, the words in the whitelist need to be extracted from the stem.
Whitelist may be as follows:
