Question

愚蠢的问题，但我不擅长从shell配置。我想在启用-DGAPING_SECURITY_HOLE选项的情况下重新编译我的netcat版本（请参阅section 0x1）。我在我的电脑上下载了源代码，我可以通过运行来正常安装：

$ ./configure
$ make

但是如何在Unix系统上启用此选项？谢谢。（这也是一个班级项目。实际上并没有试图破解......哈哈）

Answer 1

./configure  --enable-DGAPING_SECURITY_HOLE

./make

cd src

./netcat --help

Answer 2

阅读您链接的manual？它说：

- = *编译Netcat * = -

[ Enable -DGAPING_SECURITY_HOLE ]
  While this option makes netcat very powerfull, it is also a huge risk in the wrong hands.. 
   Damn hackers.

[ Enable -DTELNET ]
  Without this option netcat will be unable to connect to a telnet server. Telnet servers &
   there clients auto negotiate there options before the login prompt is displayed. Enabling 
   this option allows netcat to support this functionality.

  # DFLAGS = -DTEST -DDEBUG
  DFLAGS = -DGAPING_SECURITY_HOLE -DTELNET
  CFLAGS = -O

因此，编辑makefile并调整DFLAGS的设置。它还暗示可能是默认值。

Answer 3

尝试这样做：

./configure -DGAPING_SECURITY_HOLE
make Linux

如何用选项重新编译netcat？
