* Sepcial thx lion for his htran.c for win,Thank you:)
*
* Complie : gcc -o lhtran lhtran.c -lpthread
*
* Usage ./lhtran
* : ======================== Packet Transmit Tool V1.01 For Unix/Linux ====================
* : =========== Code by lion & bkbll, Rewritten by W.Z.T, Welcome to http://tthacker.cublog.cn ==========
* :
* : [Usage of Packet Transmit:]
* : HTran - [-log logfile]
* :
* : [option:]
* : -listen
* : -tran
* : -slave
* 2013 10 03 在mac os 10.8.5 编译提示 cast to pointer from integer of different size
* 添加arpa/inet.h
* 删除(char *)
* 正常编译通过，运行没问题
