Ping but no resolve

[7]

Hi

I boot into a boot/root disk I've made from busybox. I type:

# ifconfig eth0 hw ether 00:50:FC:23:7C:FA up # Forge MAC address of card.

# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:50:FC:23:7C:FA <- accepts new address

I'm quite lost. I have Debian (potato) installed on the computer's hard drive and the above works perfectly (the ping to yahoo returns). Does anyone know what ping: www.yahoo.com: (http://www.yahoo.com:) Resolver Error 0 (no error) means? Is it some sick joke?

Cheers.

Fascinating... I have never seen anything like that.

My guess is that it is some kind of sick joke.

Are you behind a firewall?

[7]

Nope. :(

What I'm trying to do is use a 486 as a NAT router, like this:

+~~~~~~~~~~+
| internet |------[ 486 ]----[ hub ]
+~~~~~~~~~~+ | |
<BOX 1>----+ |
+---<BOX 2>

My cable modem plugs straight into the 486.

The strange thing is that with the Debian install the above commands work perfectly. I'm using the same software (pump) to set up dhcp, so... ?

Want more strangeness?

After pump under my busybox disk, the routing tables show:


# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
62.31.151.0 * 255.255.255.0 U 0 0 0 eth0

Under Debian, right after pump I get:

Priss:~# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
62.31.151.0 * 255.255.255.0 U 0 0 0 eth0
default s01-ubr02-fn.bl 0.0.0.0 UG 0 0 0 eth0

So I try to add a default route. Back under busybox:

# route add default gw eth0
route: can't resolve gw eth0
