并不全是翻译，我补充了一些，希望对英语盲有用
文中涉及到
目录vpnclient，即PacketiX VPN 客户端的安装文件所在的目录
可执行文件vpnclient，目录vpnclient中的一个文件
可执行文件vpncmd，目录vpnclient中的一个文件
启动脚本vpnclient，我编的用来执行目录vpnclient中的可执行文件vpnclient的脚本
启动脚本vpncmd，我编的用来执行目录vpnclient中的可执行文件vpncmd的脚本

1. 安装PacketiX VPN 客户端依赖的软件包： zlib, openssl, readline, and ncurses

2. 下载PacketiX VPN 客户端，从
http://www.packetix.net/en/secure/install/
或 http://www.plathome.com/products/packetix/download.html

3. 解压PacketiX VPN 客户端的安装文件，进入安装文件所在的文件夹，编译PacketiX VPN 客户端

注释1.使用星号*可以匹配文件名中的任何字符串，考虑到以后版本解压出的目录名称部分不确定，所以在vpnclient后面加上星号
注释2.有一个隐藏文件.install.sh，用来询问用户是否同意使用协议， 不用运行它，它在make的过程中已经执行过了

4.下载secure.vpn，复制到目录vpnclient内
http://www.packetix.net/en/secure/secure.vpn

5. 我个人希望将可执行文件vpnclient和可执行文件vpncmd作为系统命令，对此没有要求的请跳过这步
将目录vpnclient复制到目录 /usr/lib下

我编了如下脚本来执行目录vpnclient内的可执行文件vpnclient和可执行文件vpncmd
启动脚本vpnclient

和
启动脚本vpncmd

下载启动脚本vpnclient和启动脚本vpncmd

文件注释: vpnclient 和 vpncmd 的启动脚本
shell-vpnclient-and-vpncmd.tar.gz [246 Bytes]
被下载 73 次

将启动脚本vpnclient和启动脚本vpncmd解压出之后复制到目录 /usr/bin下

6. 启动vpnclient

如果要退出vpnclient

7. 启动vpncmd进行设置

在第一次选择中选 2，即管理vpn客户端

然后输入要管理的vpn客户端的位置，默认是localhost

这时就出现了VPN Client>的提示符，我们就可以做下面的步骤了

8. 在vpncmd中输入niccreate来创建一个虚拟网卡

然后给这个虚拟网卡起一个名字，这里我们管它叫0

9. 检查上一步的成果，列出所有的虚拟网卡

然后就可以看到虚拟网卡的列表了

10.导入vpn账户配置文件secure.vpn，注意刚才我们已经把secure.vpn复制到目录vpnclient里了
在

然后输入我们要到入的设置文件的文件名

出现这个就说明导入成功

11.如果是手工创建vpn账户配置，假设按照secure.vpn中的内容设置，过程如下

然后给这个账户配置起一个名字

然后输入目标VPN服务器网址及端口

然后输入目标虚拟集线器名称

然后输入用户名

然后输入该设置所用的虚拟网卡的名称

12.查看我们上一步的劳动成果，列出vpn账户配置

然后会出现

13.按账户配置启动vpn连接

然后输入此次连接所使用的配置的名称，本文中是我们刚才创建的Secure

如果想退出vpncmd，则输入quit

断开的话就执行

14.将某个账户配置设成一启动vpnclient，就自动连接的方式

然后输入连接所使用的配置的名称

15.如果我们已经用某个账户配置连接VPN的话，查看连接信息
这步是在终端下执行的，不是在vpncmd下

然后出现

我自己一直执行到这一步都正常，但是虚拟网卡好像没接到笔记本的wifi网卡上，而是接到了以太网卡上，先做一下验证，剩下的我以后再翻译

PacketiX.NET vpn client installation on linux

In tips & tricks on 8 August 2009 tagged simple packetix free vpn guide with 14 comments

recently i’m been using packetix.net vpn and the speed is quite good… unfortunately there’s not many guide on how to use the client on linux, so i’m writing one.

this gonna be very long..so bear with me till the end ..huhu

0. to make things easier, lets transform into root
sudo su && cd

1. now, make a folder name vpn and download the vpnclient file from their web http://packetix.net/en/secure/install/
mkdir vpn && cd vpn
wget -c http://packetix.net/en/special/files/vp … x86.tar.gz

2. now to compile this files, you need zlib, openssl, readline and ncurses.
apt-get install zlib1g-dev libreadline5-dev

3. once finish,extract the file and continue with compile
tar -zxvf vpnclient-5350a-rtm-en-linux-x86.tar.gz && cd vpnclient* && make
4. connecting/tunneling to packettix.net
./vpnclient start
./vpncmd

5. inside vpncmd
choose number 2
[2] Management of VPN Clinet and input localhost as the destination host
u will see something like this…
Input destination: localhost
Connected to VPN Client “localhost”.
VPN Client>

6. now configuring your connection….read..and follow
root@bur8:~/vpnclient> ./vpncmd
vpncmd command – PacketiX VPN Command Line Management Utility
PacketiX VPN Command Line Management Utility (vpncmd command)
Version 2.20 Build 5350 (English)
Compiled Oct 9 2007 01:27:58 by yagi at ILC308

By using vpncmd program, the following can be achieved.
1. Management of VPN Server or VPN Bridge
2. Management of VPN Clinet
3. Use of VPN Tools (certificate creation and communication speed measurement)

Select 1, 2 or 3: 2

Specify the host name or IP address of the computer that the destination VPN Client is operating on.
If nothing is input and Enter is pressed, connection will be made to localhost (this computer).
Input destination: localhost

Connected to VPN Client “localhost”.
VPN Client>niccreate
NicCreate command – Create New Virtual Network Adapter

The command terminated normally.

*** now lets configure our account and connection

7. now check for connection… note the value of _0 at the end of vpn
root@bur8:~/vpnclient> ifconfig vpn_0
vpn_0 Link encap:Ethernet HWaddr 00:ac:9d:03:5c:f6
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:463867 (463.8 KB) TX bytes:0 (0.0 B)

7. get dhcp from vpn
root@bur8:~/vpnclient> dhclient vpn_0

Sending on LPF/vpn_0/00:ac:9d:03:5c:f6

root@bur8:~/vpnclient> ifconfig vpn_0
vpn_0 Link encap:Ethernet HWaddr 00:ac:9d:03:5c:f6
inet addr:10.3.83.250 Bcast:10.255.255.255 Mask:255.0.0.0

now you can start routing you connection to vpn..
sorry but this is a noob routing technique…it will redirect all your traffic to vpn

route del default
route add default dev vpn_0

for more about how to do advance routing in linux please refer to http://lartc.org/howto/index.html
p/s: to back to your current connection.. stop the service and reroute back to your original gateway.
in my case
./vpnclient stop
route del default
route add default dev ppp0
where ppp0 is my celcom 3g modem interface

for those who didn’t know what the hell packetix.net is….

PacketiX.NET is an academic, non-profit online environment for PacketiX VPN, the VPN technology developed by SoftEther Corporation.

more info please visit their website at http://packetix.net/en/

update: you need to enable ipforwarding or else you won’t be able to connect to internet.
$ echo 1 > /proc/sys/net/ipv4/ip_forward
or simply edit your /etc/sysctl.conf file

hope it this guide will give benefit to everyone.. thank you

PacketiX VPN是日本的一个VPN软件可以用来翻墙（参考一、二、三），不知道现在还能不能用；文中方法我没有测试，不知道能不能成功，有兴趣的可以试试。
