一、配置proxychains

# vim /etc/proxychains.conf

# proxychains.conf  VER 3.1
#
#        HTTP, SOCKS4, SOCKS5 tunneling proxifier with DNS.
#	

# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see  chain_len) from the list.
# this option is good to test your IDS :)

# Make sense only if random_chain
#chain_len = 2

# Quiet mode (no output from library)
#quiet_mode

# Proxy DNS requests - no leak for DNS data
proxy_dns 

# Some timeouts in milliseconds
tcp_read_time_out 15000
tcp_connect_time_out 8000

# ProxyList format
#       type  host  port [user pass]
#       (values separated by 'tab' or 'blank')
#
#
#        Examples:
#
#            	socks5	192.168.67.78	1080	lamer	secret
#		http	192.168.89.3	8080	justu	hidden
#	 	socks4	192.168.1.49	1080
#	        http	192.168.39.93	8080	
#		
#
#       proxy types: http, socks4, socks5
#        ( auth types supported: "basic"-http  "user/pass"-socks )
#
[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
# socks4 	127.0.0.1 9050
socks5  127.0.0.1 1080

二、安装shadowsocks

# apt install python-pip && pip install shadowsocks

三、配置shadowsocks

# mkdir /home/ss && cd /root/home && vim ssserver.json

{
    "server": "my_server_ip", // 这里输入墙外服务器地址
    "server_port": 8080, // 墙外服务器的端口
    "local_address": "127.0.0.1",
    "local_port": 1080, // 为了安全，可修改为大于 1024 的数字
    "password": "mypassword", // 设置一个密码
    "timeout": 300,
    "method": "aes-256-cfb",//要和服务端的加密方式相同
    "fast_open": false
}

四、启动代理

# sslocal -c /home/ss/ssserver.json -d restart

# proxychains firefox
