[讨论]问一个ubuntu挂起的问题

[rucstudent]

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
