让SSH/SOCKS成为全局代理的软件们（Windows+Linux） ^有更新！

Windows下的有：

1. Proxifier 下载地址
2. ProxyCap 下载地址

前者比较好用，可控规则较多。我正在使用。

Linux下的有：

1. proxychains 下载地址
2. redsocks 下载地址
3. tsocks 下载地址

proxychain功能较多，支持多个代理轮询等；redsocks据说支持android；tsocks配置简单。

proxychains教程

假设代理为127.0.0.1，端口为7070。我在Ubuntu下安装。

安装很简单：

sudo apt-get install proxychains

配置：

sudo vi /etc/proxychains.conf

把最后的“[ProxyList]”部分配置为自己的代理即可：

socks4 127.0.0.1 7070

使用方法：

proxychains <程序名>

即可让程序使用代理。

redsocks教程

严格意义上来说，proxychains不算自动的全局代理，有没有像Proxifier这样，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' andport’ 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' andport’ 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' andredudp’ 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）：

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
