1.首先在google code中找到ruijieclient项目
其下载地址如下：
http://code.google.com/p/ruijieclient/downloads/list

2.选择你要的软件包deb或者rpm和版本
Ubuntu用户就可以直接下载deb包，fedora用户选择rpm包
下载之后可以之间点击安装
安装后运行命令：sudo ruijieclient
出现以下提示的话：
ruijieclient: error while loading shared libraries: libpcap.so: cannot open shared object file: No such file or directory

那么你可以到下面网站下一个libpcap0.8_1.1.1-2_i386.deb包
地址：http://packages.ubuntu.com/zh-cn/maverick/i386/libpcap0.8/download
最好是点亚洲源下载
安装此包。

3.安装完成之后
命令：sudo gedit /etc/ruijie.conf
对配置文件进行修改，有三个地方需要修改，红字已经指出

<?xml version=”1.0″ encoding=”UTF-8″?>
<ruijie.conf version=”0.8.1svn129″>
  <!–This is a sample configuration file of RuijieClient, change it appropriately according to your settings.–>

    <!–Add if you don’t want ruijieclient to ping the default gateway–>
    <PingHost></PingHost>
  </settings>
</ruijie.conf>

4.使用锐捷终端命令：sudo ruijieclient

5.关闭锐捷终端命令：sudo ruijieclient -k
