Issue: When a shared folder is mounted in HyperTerminal, when communication between the Board and the virtual machine is established, the "Mount-t nfs-o nolock 192.168.0.234:/root/bc/host" command is found to fail to run the hello executable file in HyperTerminalWorkaround: After the failu
This app is the love of countless otaku, also known as the "gun artifact", its registered users have reached 80 million, but heard that they are very strict protection of the app, to prevent users from packaging two times. Now let's analyze How secure this app is . First, we analyze the next two packaging protection, we first go online to find the app's installation package, unpacking-- > Pack-and-run. found that when we log in, we will be prompted that the signature information is inconsistent,

Compile driver module and test program
There are two methods of compiling in Makefile, which can also be compiled using GCC on this machine or cross compiler, which is compiled by the cross compiler.
Test driver
If you compile with GCC, you need to set up the device node with the following command, an

There may be some gaps with the expected results. The actual command has been run, but the returned results are not visible. because this is a real GIF file, the returned results are not displayed, to verify whether the command is actually executed, we perform the file upload command. As expected, the file has been successfully uploaded to the server. The advantage of this fabricated scheme is that it has good hiding ability. Not to mention the problem. If you want to see the returned results, t
