关于loopback

[chu887]

这是我的网卡配置情况，eth1是无线网卡，p3p1是有线网卡

关于lo 第一行 <>里头的 RUNNING 看着怎么不爽呢，我记得 以前好像没有的， 怎么关掉阿？
我说的不是 sudo ifconfig lo down， 而是 把那个 RUNNING 关闭。。。

亲，你关掉吧，你就关掉吧，关掉我就不信你不会回来哭。

即使我运行　sudo ifconfig lo down ,也对我上网没有丝毫影响阿。。。还请楼上明讲

你确定你能关闭这设备？这是本地两个进程之间通信用的吧，用于模拟网络行为的。

天啊，当我路过的算了。

你的系统不可以么? 忘了说了，我的是　fedora17....10.4后没再用过ubuntu..

[YeLee]

好吧，可以关掉，也许真的是我杞人忧天了吧，反正是一个127.0.0.1而已。
