Stunnel

1.更新软件包信息

apt-get update

2.下载stunnel

apt-get install stunnel

3.进入这个目录之后会看到有一个配置文件 /usr/share/doc/stunnel4/examples/stunnel.conf-sample

cd /etc/stunnel

4.将该配置文件备份

cp /usr/share/doc/stunnel4/examples/stunnel.conf-sample stunnel.conf

5.修改当前的这个配置文件

首先指定 cert 和 key:

cert = /etc/stunnel/stunnel.pem
key = /etc/stunnel/stunnel.pem

这个key文件(“stunnel.pem”)我们稍后生成。

然后注释掉所有的默认服务,而只保留[https]这一节,不过我这里把https里的connect端口设置为了8443,这里的意思就是,Stunnel会在这台主机上监听443端口,并将连接转到8443端口上。所以你的主机上需要在8443端口有一个服务。而这个服务,稍后我们将安装一个Squid来提供。

;[pop3s]
;accept  = 995
;connect = 110

;[imaps]
;accept  = 993
;connect = 143

;[ssmtp]
;accept  = 465
;connect = 25

[https]
accept  = 443
connect = 8443
;TIMEOUTclose = 0

其他配置方面,可以先打开详尽的日志记录以方便调试:

; Some debugging stuff useful for troubleshooting
debug = 7
output = /var/log/stunnel4/stunnel.log

测试完毕后,建议将上面的 “debug = 7″ 注释掉(顺便提及,注释就是用‘;‘开头的行),或者修改为5以下的数值。保留在7会产生大量的日志,日志文件很快就会变的很大。

另外,默认配置文件是采用了chroot机制,如下所示,这段不需要修改,使用起来没有问题:

; Some security enhancements for UNIX systems - comment them out on Win32
chroot = /var/lib/stunnel4/
setuid = stunnel4
setgid = stunnel4
; PID is created inside the chroot jail
pid = /stunnel4.pid

这就是Stunnel的配置文件,本身就是很简单的一个配置文件,主要就是设置了一下key文件的路径,然后指定了服务端口。

不过除此之外,还要修改一个地方:

# cd /etc/default
# vi stunnel4

这里要设置为ENABLED=1,默认是不使能stunnel服务的:

# Change to one to enable stunnel automatic startup
ENABLED=1

 

5.生成key并启动Stunnel服务

启动stunnel服务之前,需要生成一组密钥:

# cd /etc/stunnel
# openssl req -new -nodes -x509 -out stunnel.pem -keyout stunnel.pem

运行命令后,终端上会有几个问题需要你输入你的设定,基本没有什么意义,自己随便给吧:

root@czy-virtual-machine:/etc/stunnel# openssl req -new -nodes -x509 -out stunnel.pem -keyout stunnel.pem
