设置proxychains

设置ProxyChains

sudo apt-get install proxychains
sudo gedit /etc/proxychains.conf

修改端口：

# defaults set to "tor"
socks5 	127.0.0.1 1088

1088为梯子端口号，从agent软件中获取

然后运行

sudo proxychains wget  google.com

结果：

疑难杂症

出现报错

ERROR: ld.so: object 'libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

$ proxychains ping google.com
ProxyChains-3.1 (http://proxychains.sf.net)
ERROR: ld.so: object 'libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
PING google.com (142.251.43.14) 56(84) bytes of data.

问题:
libproxychains.so.3 找不到
解决：
先找一下libproxychains.so.3 在哪里
得知位置：libproxychains.so: /usr/lib/x86_64-linux-gnu/libproxychains.so.3

whereis libproxychains.so.3  
libproxychains.so: /usr/lib/x86_64-linux-gnu/libproxychains.so.3

修改：/usr/bin/proxychains

code /usr/bin/proxychains

#!/bin/sh
echo "ProxyChains-3.1 (http://proxychains.sf.net)"
if [ $# = 0 ] ; then
	echo "	usage:"
	echo "		proxychains <prog> [args]"
	exit
fi
#export LD_PRELOAD=libproxychains.so.3
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
exec "$@"

验证修改：

sudo cat /usr/bin/proxychains
#!/bin/sh
echo "ProxyChains-3.1 (http://proxychains.sf.net)"
if [ $# = 0 ] ; then
	echo "	usage:"
	echo "		proxychains <prog> [args]"
	exit
fi
#export LD_PRELOAD=libproxychains.so.3
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
exec "$@"

验证是否配置成功

$ sudo proxychains wget  google.com

ProxyChains是什么：
ProxyChains是Linux和其他Unices下的agent工具。它可以使任何程序通过agent上网，允许TCP和DNS通过agent隧道，支持HTTP、SOCKS4和SOCKS5类型的agent服务器，并且可配置多个agent。ProxyChains通过一个用户定义的agent列表强制连接指定的应用程序，直接断开接收方和发送方的连接。
