RF 6 SP2 下无线网络设置-红联Linux系统门户

redflag 6 sp2 无线网络设置

这些天一直在学习REDFLAG ，装了RF 6 SP2 , 和RF 7，用了感觉还是6 亲和些，就集中精力学RF6 了。

前些天无线网卡己能在RF6 SP2下上网，史是在RF7 下还是没搞定，过些天再去研究下。

今天己把无线网卡PING 不到内网的原因找到了，因为我还有一张有线网卡，也是自动开启的，所以有如下路由：
[root@rf6net ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0
169.254.0.0 * 255.255.0.0 U 0 0 0 wlan0
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

里面没有我无线网卡的路由地址，所以前些天开机总要在终端加上。
[root@rf6net ~]# route add default gw 192.168.1.1
SIOCADDRT: 文件已存在
[root@rf6net ~]# route add default gw 192.168.1.1 wlan0
[root@rf6net ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0
169.254.0.0 * 255.255.0.0 U 0 0 0 wlan0
default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

这样加上后就能打开网页了，但是PING 不通内网192.168.1. ，当时只要能上网就很高兴了，也没去想是什么原因，今天有空，
把原因找出来了。

1。因为路由是依照顺序来排列和传输的，所以当我PING 内网段时，总是由eth0 的192.168.1.0 网域送出去，可是我没有按网线，当然是PING 不通，
可系统不会依次找下去。但PING 外网段时，系统就找那default 网域，虽然我有两个default,但注意看了，是那无线的在前，所以能PING 通。
[root@rf6net ~]# ping 192.168.1.6

想通这点后为了验证，我就把其它的一些网域都DEL ，看还能不能PING 。

删了那个169.254.0.0的，还是不能ping 通，

删了那个无线的192.168.1.0也还是不能ping 通。

OK，删了那个eth0后就可以了。这里我是把那两个192.168.1.0的都删了，不过，先删这个eth0的，把wlan0的留下，也能ping通了。

最后只留两个，因为一个169.254.0.0怎么也删不了，删了又出来了。就不管他先。

只留两个：

[root@rf6net ~]#

这样上网一切正常，

只有这个问题，169.254.0.0是什么网域，怎么del 了又会出来？

[root@rf6net ~]# route
Kernel IP routing table

169.254.0.0 * 255.255.0.0 U 0 0 0 wlan0

[root@rf6net ~]# route del -net 169.254.0.0 netmask 255.255.0.0 wlan0
[root@rf6net ~]# route
