Supplicant For LINUX V1.1.1.rar好像是这个文件，我的是学校网站上下的，我记得两者是一样的

解压直接拷贝到 /usr/bin或/usr/local/bin下，以便在任何目录下都能使用。我是在Fedora Core 7下进行的。

#在系统－－管理－－网络下配置好ip,DNS等

#并激活eth0设备

#接着运行它：
[root@localhost ~]# xrgsu
xrgsu: error while loading shared libraries: libpcap.so.0.6.2:
cannot open shared object file: No such file or directory

#你会发现在/usr/lib/下有这个libpcap.so.0.9的版本，作个软链接如下，版本能兼容

[root@localhost ~]# ln -s /usr/lib/libpcap.so.0.9 /usr/lib/libpcap.so.0.6.2
[root@localhost ~]# xrgsu
xrgsu: error while loading shared libraries: libstdc++.so.5:
cannot open shared object file: No such file or directory
[root@localhost ~]# ln -s '/usr/lib/libstdc++.so.6' '/usr/lib/libstdc++.so.5'
[root@localhost ~]# xrgsu
xrgsu: /usr/lib/libstdc++.so.5: version `GLIBCPP_3.2' not found (required by xrgsu)
#libstdc++.so.6与libstdc++.so.5

不兼容，得安装compat-libstdc+ +-33-3.2.3-61.i386.rpm

#里面有libstdc++.so.5。下载双击它即可安装。再运行
[root@localhost ~]# xrgsu
