求助！evolution插入网络上文件问题？

我是学校教育网，每次要用xsupplicant拨号上网
每次用ubuntu挂起功能的时候，再次唤醒的时候，就尚不了网了，
于是就在每次挂起前，用命令：sudo killall xsupplicant结束xsupplicant的进程
然后唤醒的时候再拨一次号：xsupplicant -i eth0
但是返回这样的结果：里面的星号是我的用户名和密码，我处理了一下
请问怎样操作才能让挂起后的电脑还能上网，或者重新使用xsupplicant拨号上网呢？


sudo killall xsupplicant
但是唤醒之后
执行
xsupplicant -i eth0
以后返回结果如下：

lanpeng@lanpeng-laptop:~$ xsupplicant -i eth0

Couldn't initialize raw socket for interface eth0!
Couldn't initalize!!!!

很想知道最后是怎么解决的？

不过，我也在用你说的xsupplicant，可我用的是ubuntu linux，学校里只提供里red hat的linux版本，所以我用alien工具将.rpm包转化成了.deb包，然后安装上去了，但是我输入命令sudo **supplicant -i eth0 -u *********（用户名） -t 2后，显示 如下：
Using default config!
Interface initalized!
No configuration information for network "(null)" found. Using default.
Please Input password:

"some command"
Defaulting to AUTHENTICATED state!
请问该如何解决？
