network tools don't work

[Kwansuk Kim]

After getting bash prompt, I determined wheather network is working, but it doesn't.
It tells there is no protocol.

But I set configure file to support TCP/IP protocol.
It's startup message.

Is something wrong?

I used ramdisk root file system, and ramdisk image was obtained from linuxppc.org. (about 4Meg, library version is 1.99)
