1.首先從網路上找到 socks5-v1.0r11.tar.gz ，還有一個是補丁包，那個包沒有下，所以有什麼用我不知道。
2.講socks5-v1.0r11.tar.gz解壓倒文件夾，利用下面這個命令，其實這幾步網路上的資源很豐富，但我這裡力求詳細和全面。
解壓上述壓縮包，執行tar xvzf socks5-v1.0r11.tar.gz
解壓縮后在目錄下產生一個 socks5-v.1.0r11的目錄。
3.進入該目錄，運行./configure .這一步我順利通過。
4.接著運行make,在編譯的過程中遇到了問題，讓我花了好長時間，在編譯clients/ftp/ftp.c文件時，在command函數處出現問題，提示說arargs方法在gcc4.1.2中已經過時，不能用了。但是網上我沒有找到可用的解決方法。所以只有自己解決，具體問題是varargs.h和stdarg.h的不兼容，就是說在處理不確定個數的參數的時候方法不同，現在的gcc已經用了stdarg方法，已經不用ararg的方法。兩者的差異在於，va_start()函數的參數個數不同，格式也不一樣，下面我同時列給出我修改的代碼和原來的代碼：
原來的代碼：
#include .... int command(va_alist) va_dcl { va_list ap; char *fmt; int r; Sig_t oldintr; abrtflag = 0; if (debug) { printf("---> "); va_start(ap); fmt = va_arg(ap, char *); if (strncmp("PASS ", fmt, 5) == 0) printf("PASS XXXX"); else vfprintf(stdout, fmt, ap); va_end(ap); printf("\n"); fflush(stdout); } if (cout == NULL) { perror ("No control connection for command"); code = -1; return (0); } oldintr = Signal(SIGINT, cmdabort); va_start(ap); fmt = va_arg(ap, char *); vfprintf(cout, fmt, ap); va_end(ap); fflush(cout); cpend = 1; r = getreply(!strcmp(fmt, "QUIT")); Signal(SIGINT, oldintr); if (abrtflag) { kill(getpid(),SIGINT); } return(r); } |
修改過的代碼：
//#include #include .... /*VARARGS*/ int command(const char *args,...) { va_list ap; char *fmt; int r; Sig_t oldintr; abrtflag = 0; if (cout == NULL) { perror ("No control connection for command"); code = -1; return (0); } oldintr = Signal(SIGINT, cmdabort); fmt = args; va_start(ap,args); // fmt = va_arg(ap, char *); vfprintf(cout, fmt, ap); va_end(ap); fflush(cout); cpend = 1; r = getreply(!strcmp(fmt, "QUIT")); Signal(SIGINT, oldintr); if (abrtflag) { kill(getpid(),SIGINT); } return(r); } |
這個函數修改過以後，後面還有一個文件clients/telnet/commands.c中的call（）函數也要做類是的修改。
這裡我推介大家看看有關va_start(),va_end的文章；想更深層的可以看看標準c語言中的va函數的用法。
5.當編譯完全通過以後，運行make install 。
此時可以說工作已經完成了一半，接下來就是要建立以個配置文件sock5.conf,關於這個配置文件倒是比較簡單，網路上別的資源也很多，在此就不累述。
6.本以為已經沒有什麼問題了，卻發現運行程序時又出現問題了。剛開始我是使用socks5 -f -s 能運行，但是在另外一台機子上用qq程序進行登錄測試，顯示代理伺服器正常，但是無法傳輸數據，顯示如下：

進行了好幾次重複都不行，具體問題在哪裡還沒找到。後來看到網上有人提議說利用這個命令可以試一下：socks5 -p -f,測試成功。
