Linux下成功安装和配置Sock5代理的过程

来源:赛迪网 作者:sixth
　　 

1.首先从网络上找到 socks5-v1.0r11.tar.gz ，还有一个是补丁包，那个包没有下，所以有什么用我不知道。

2.讲socks5-v1.0r11.tar.gz解压倒文件夹，利用下面这个命令，其实这几步网络上的资源很丰富，但我这里力求详细和全面。

解压上述压缩包，执行tar xvzf socks5-v1.0r11.tar.gz

解压缩后在目录下产生一个 socks5-v.1.0r11的目录。

3.进入该目录，运行./configure .这一步我顺利通过。

4.接着运行make,在编译的过程中遇到了问题，让我花了好长时间，在编译clients/ftp/ftp.c文件时，在command函数处出现问题，提示说arargs方法在gcc4.1.2中已经过时，不能用了。但是网上我没有找到可用的解决方法。所以只有自己解决，具体问题是varargs.h和stdarg.h的不兼容，就是说在处理不确定个数的参数的时候方法不同，现在的gcc已经用了stdarg方法，已经不用ararg的方法。两者的差异在于，va_start()函数的参数个数不同，格式也不一样，下面我同时列给出我修改的代码和原来的代码：

 

原来的代码：

 

 

#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);
}

 

修改过的代码：

 

 

//#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);
}

 

这个函数修改过以后，后面还有一个文件clients/telnet/commands.c中的call（）函数也要做类是的修改。

 

这里我推介大家看看有关va_start(),va_end的文章；想更深层的可以看看标准c语言中的va函数的用法。

 

 

5.当编译完全通过以后，运行make install 。

 

此时可以说工作已经完成了一半，接下来就是要建立以个配置文件sock5.conf,关于这个配置文件倒是比较简单，网络上别的资源也很多，在此就不累述。

 

6.本以为已经没有什么问题了，却发现运行程序时又出现问题了。刚开始我是使用socks5 -f -s 能运行，但是在另外一台机子上用qq程序进行登录测试，显示代理服务器正常，但是无法传输数据，显示如下：

进行了好几次重复都不行，具体问题在哪里还没找到。后来看到网上有人提议说利用这个命令可以试一下：socks5 -p -f,测试成功。
