求助 让skyeye 支持网络的问题
我搞了很久多ping不通，我的过程
安装uclinux for skyey 的网络设备驱动的补丁
编译 uclinux 选择了新增的skyeye网络设备
编写skyeye.conf文件增加网络选项类型为tun
按照skyeye 中readme增加了linux中的tun.o模块
开始执行uclinux就是ping不通主机且运行ifconfig时，
提示没编译有error出现。然后采用vnet 我也试过，一样的结果。 需要把你的skyeye.conf文件, skyeye的执行显示都列出来看看 cpu: arm7tdmi

这个应该不会有错误吧 还缺少你的skyeye运行的情况显示。
在skyeye运行后，用
lsmod运行一下，把它的输出显示给我看看。 在这里先谢谢版主了,
lsmod 是在linux中还是在skyeye uclinxu中运行啊两种结果我多显示一下
linux 中的

2: 当uclinux执行到shell后，在宿主机上运行ifconfig ，把它的输出给我看看。
3： 当uclinux执行到shell后，在shell中运行ifconfig ,把它的结果给我看看。如果没有输出，请在编译busybox时把ifconfig的信息输出支持加上。
注意，2应该有一个tap0的网络界面 网络地址为192.168.168.11
3应该有一个eth0的网络界面，网络地址为192.168.168.x
感觉你快成功了。 我的skyeye 版本应该是0.7.0的(skyeye-0.7.0.tar.bz2)
网络设备是按照这个uclinux4skyeye-v0.2.3.tgz做的
skyeye 中的网络有问题啊,怎么办,是不是网卡驱动有问题啊

#ifconfig eth0 down
#ifconfig eth0 192.168.11.10
＃ifconfig
看看是否eth0的输出有IP地址了。
如果还没有，可能是你自己加uclinux 网络驱动的过程不对。
建议用skyeye-0.7.4
还有就是你用用 skyeye-testsuit-1.0.4中的AT91目录下有网络配置的编译好的uclinux运行试试，看看网络通否。
我的问题！
不知道兄弟调通没，我也有问题！我是在VMware 上安装的Redhat9.0,然后安装skyeye0.7.7和uClinux!
在Skyeye下运行uClinux,老是提示：/bin/ifconfig up 10.0.0.2
我用ifconfig 配置eth0为192。168。0。84（或８３），可以看到eth0配置是对的！只是发觉接受和发送包都为0;
在linux 下我也可以看见ifconfig 包括了tap0:198。168.0。83，也发觉接受和发送包都为0;
（我的主机ip是192.168.0.81,VMware下的linux IP 192.168.0.82,他们通讯正常；skyeye 下lsmod 也可以看到有tun模块！）
但是我进入uCLinux后ping 谁都死在哪！：（：（
请大虾们帮帮忙！
楼主有没有搞定?
我这类问题也很相似
因为用redhat as3, 里面没有tun,编译内核又过不去
所以用了vnet
改了skyeye.conf, 启动uclinux没有问题
但是不管是主机下ping还是uclinux下ping
都是unreachable
