求助：Rh与 (skyeye+uclinux)通信问题？
我的OS是Redhat9.0,skyeye0.7.0,uClinux-dist-20030522,按照大侠指点顺利安装成功,并且加入了网络功能：Command: hostname GDB-ARMulator
Command: /bin/expand /etc/ramfs.img /dev/ram0
Command: mount -t proc proc /proc
mount: /etc/mtab: Read-only file system
Command: mount -t ext2 /dev/ram0 /var
mount: /etc/mtab: Read-only file system
Command: mkdir /var/tmp
Command: mkdir /var/log
Command: mkdir /var/run
Command: mkdir /var/lock
Command: cat /etc/motd

主机ping虚拟网络如下：

我在仿真环境中ping,有如下显示：

这是不是表明两端不能通信？小弟是新手，请大侠，兄弟们指点一二，
这里先谢过了！！！ 我来回答一下：
两端已经可以通信了，因为uclinux的10.0.0.2可以和red hat的10.0.0.1相互ping
通。
之所以uclinux不能ping通192.168.5.10，是因为你没有在uclinux上增加一条destination 192.168.5.0 nexthop 10.0.0.1的路由。增加后就可以ping 通192.168.5.10了。
或者干脆一点：增加一条缺省路由 destnation 0.0.0.0nexthop 10.0.0.1 Thanks, 搞定！ Thanks, 搞定！ 或者干脆一点：增加一条缺省路由 destnation 0.0.0.0 nexthop 10.0.0.1
具体怎么做阿??????????
