redsocks教程

严格意义上来说,proxychains不算自动的全局代理,那么有没有像Proxifier那样的程序-开了之后,自动让所有启动的程序都走系统代理呢?答案就是redsocks。
首先安装Ubuntu编译环境和必要的库:
sudo apt-get install autoconf automake libtool libevent-dev g++
下载源代码,然后编译安装:
./mkauto.sh
cp redsocks /usr/local/bin/
配置文件为:
base {
// debug: connection progress & client list on SIGUSR1
log_debug = off;
// info: start and end of client session
log_info = off;
/* possible `log’ values are:
* stderr
* file:/path/to/file
* syslog:FACILITY facility is any of "daemon", "local0"…"local7"
*/
log = "file:/dev/null";
// log = stderr;
// log = "file:/path/to/file";
// log = "syslog:local7";
// detach from console
daemon = on;
/* Change uid, gid and root directory, these options require root
* privilegies on startup.
* Note, your chroot may requre /etc/localtime if you write log to syslog.
* Log is opened before chroot & uid changing.
*/
// user = nobody;
// group = nobody;
// chroot = "/var/chroot";
/* possible `redirector’ values are:
* iptables – for Linux
* ipf – for FreeBSD
* pf – for OpenBSD
* generic – some generic redirector that MAY work
*/
redirector = iptables;
}
redsocks {
/* `local_ip’ defaults to 127.0.0.1 for security reasons,
* use 0.0.0.0 if you want to listen on every interface.
* `local_*’ are used as port to redirect to.
*/
local_ip = 127.0.0.1;
local_port = 12345;
// `ip’ and `port’ are IP and tcp-port of proxy-server
ip = 127.0.0.1;
port = 7070;
// known types: socks4, socks5, http-connect, http-relay
type = socks5;
// login = "foobar";
// password = "baz";
}
redudp {
// `local_ip’ should not be 0.0.0.0 as it’s also used for outgoing
// packets that are sent as replies – and it should be fixed
// if we want NAT to work properly.
local_ip = 127.0.0.1;
local_port = 10053;
// `ip’ and `port’ of socks5 proxy server.
ip = 10.0.0.1;
port = 1080;
login = username;
password = pazzw0rd;
// kernel does not give us this information, so we have to duplicate it
// in both iptables rules and configuration file. By the way, you can
// set `local_ip’ to 127.45.67.89 if you need more than 65535 ports to
// forward
// This limitation may be relaxed in future versions using contrack-tools.
dest_ip = 8.8.8.8;
dest_port = 53;
udp_timeout = 30;
udp_timeout_stream = 180;
}
dnstc {
// fake and really dumb DNS server that returns "truncated answer" to
// every query via UDP, RFC-compliant resolver should repeat same query
// via TCP in this case.
local_ip = 127.0.0.1;
local_port = 5300;
}
// you can add more `redsocks’ and `redudp’ sections if you need.
这里的配置没有配置udp的代理部分,只是配置了tcp即redsocks部分。监听端口是12345。日志关闭了,因为好像我下载的当前版本无论怎么样都产生一堆调试日志,不知道以后会不会修复这点。
启动关闭脚本redsocks.sh为(via):
#! /bin/bash

SSHPORT=22

    kill $PID
    while [ -d /proc/$PID ];
    do
    sleep 1

iptables的规则是让所有的TCP包都发送到redsocks监听的端口12345。本脚本还整合了ssh的daemon启动,使用start-stop-daemon来实现。
启动和关闭:
将启动关闭脚本中的开头的几个变量配置好
启动命令:sudo ./redsocks.sh start
关闭命令:sudo ./redsocks.sh stop
