Nmap help documentWhat is nmap?
Nmap (Network ER) is an open-source Network detection and security audit tool. Its design goal is to quickly scan a large network. Of course, it is no problem to scan a single host with it.
We recommend that you use ctrl + f for search.
In fact, it is also convenient for you to remember at the same time

Ant's buildfile is written in XML. Each buildfile contains a project.
Each task element in buildfile can have an id attribute that can be used to reference a specified task. This value must be unique. (For details, refer to the following task Section)

-1.7.0. after entering the e-disk, run the ant command to view the running result, as shown in:
Because the basedir value is set, the value of the basedir attribute is changed to the value set by the reader. You can remove the basedir attribute of the project element and run ant to check the running result. The basedir value is E:/, which is the parent directory of the ant component file. Sometimes, you may want to get the names of all targets in a
The android source code of Freescale imx53 has been compiled together over the past few days. Today, when compiling Android kernel, we found that the driver modules configured in the make menuconfig mode are not compiled.
Previously, the kernel was compiled by running the following command according to the original documents:

By checking the makefile of the kernel, you can find some clues. Now you can record your work notes as follows:
