注释的地方都是什么意思啊？是我内核配置的问题？还是我的文件系统制作时的我问题？我查看了我的配置，该有的我都有了......

/dev 里面的设备有问题？

ksh

两个问题：
1. 阅读如下警告：
NOTICE: you should be root at first !!!
NOTICE: you should inmod linux kernel net driver tun.o!!!
NOTICE: if you don't make device node, you should do commands:
NOTICE:    mkdir /dev/net; mknod /dev/net/tun c 10 200
NOTICE: now the net simulation function can not support!!!
NOTICE: Please read SkyEye.README and try again!!!

你应该用root用户运行这个示例，因为在运行网卡模拟的时候，需要插入tun.o的内核模块

boy0673

在做根文件系统时，把mkdir /dev/net; mknod /dev/net/tun c 10 200已经做了
问题主要出在：没有tun.o,                 而生成tun.o模块需要重新配置内核...
两个问题：
     1， 我配置内核时 make menuconfig， 不认识network driver 里能生成tun.o的相关项目...
     2，是不是生成tun.o模块后，在重新把这个模块添加到initrd.img里，运行skyeye，insmod？
请高手予以指点...

boy0673

我错了...真得是权限问题啊....苦死我了..
sudo skyeye -e  vmlinux

... ...
Cirrus Logic CS8900A driver for Linux (Modified for SMDK2410)
eth0: CS8900A rev D at 0xe0000300 irq=53, no eeprom , addr: 08: 0:3E:26:0A:5B
... ....
看来我的内核配置绝对没有问题...但是我想再问一下怎么在内核配置里编译出tun.o这种模块文件...相应的配置项目是？
