1 backgroundWhile learning some of the vulnerabilities on Linux systems, it often requires "field testing", but debugging on a Linux system is not very convenient, because the Linux comes with the GDB debugging tool is really not very human, even if there is a gdbtui such as "pseudo-graphical interface debugger", also with Ida The debugger, such as pro, is far ap

The reason is that after the change of UTF-8, the original code in the Chinese is not automatically converted to UTF-8 encoding, but the display is Chinese rather than garbled, so you need to remove all the Chinese and then typ

the interface sending buffer. For TCP interfaces, the default value is 2048. For the low-tide limit of UDP usage, because the number of bytes in the available space in the sending buffer is never changed, as long as the buffer size of the UDP interface sending is greater than the low-tide limit of the Set interface, this UDP interface is always writable. UDP has no sending buffer, only the size of the sending buffer.

ArchitectureValgrind includes some of the following tools:
Memcheck. This is the most widely used tool in Valgrind, a heavyweight memory checker that discovers most memory errors in development, such as using uninitialized memory, using freed memory, memory access, and so on. This is also the part that this article will focus on.
Callgrind. It is primarily used to check for problems that occur during function calls in the program.
Cachegrind. It is primarily used to check for p

I found that some students often spend a long time learning how to use a compilation tool when learning a language.RealIt's quite confusing.. There are not only many compilation tools, but also continuous elimination. We know that the C compilation tools are (turboc, Vc, Vim, ADS .......) if we spend a lot of time mastering them, it would be a great tragedy. It is vital that we spend a lot of time learning a language. I hope you only have a rough understa

Sendmail
In recent years, the security of Sendmail has improved a lot (in the past, it was usually a program that hackers attacked ). However, Sendmail still has a serious problem. Once a security vulnerability occurs (for example, a Linux kernel error occurs recently), Sendmail is a program that has been attacked by hackers, because Sendmail runs with root permission and the code is huge and prone to problems.
