network tools don't work

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.

----------

init-2.00# ./ifconfig lo 127.0.0.1
127.0.0.1: Resolver Error 0 (no error)

ping: unknown protocol icmp.
init-2.00#

----------

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)

hi, kim
I experienced similar case.
That's your shared objs and your applications are not accordant.
Build apps and kernel with same version of glibc.
also,make sure you have same version libc.so.6 in /lib of your target rootfs .

regards.
john zhan.

What is wrong is that there is no /etc/protocols file.
Try it:
	# mv /etc/protocols /etc/protocols.none
	# ping 127.0.0.1
	ping: unknown protocol icmp.
	# mv /etc/protocols.none /etc/protocols
