[Grml] Badly need help -- can't get onto network

Hi

I'm using grml 0.7 for quite a while. But this morning I woke up to find
that I can't access my Internet anymore. Everything was fine last night
and I didn't touch anything...

Here are the symptoms:

  % /etc/init.d/networking restart
  Reconfiguring network interfaces...ifup: interface lo already configured
  done.

Why the message only says interface lo, but not eth0?

  $ route
  Kernel IP routing table
  Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  192.168.2.0     *               255.255.255.0   U     0      0        0 eth0
  default         192.168.2.1     0.0.0.0         UG    0      0        0 eth0

  $ ping grml.org 
  ping: unknown host grml.org

Note that the "default" line from route took a long time to show up, so
is the "unknown host" line from ping.

  % ifconfig eth0 down

  $ ifconfig -a
  eth0      Link encap:Ethernet  HWaddr 00:11:2F:BE:4B:BA  
	    inet addr:192.168.2.13  Bcast:192.168.2.255  Mask:255.255.255.0
	    BROADCAST MULTICAST  MTU:1500  Metric:1
	    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
	    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
	    collisions:0 txqueuelen:1000 
	    RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
	    Interrupt:185 

  lo        Link encap:Local Loopback  
	    inet addr:127.0.0.1  Mask:255.0.0.0
	    inet6 addr: ::1/128 Scope:Host
	    UP LOOPBACK RUNNING  MTU:16436  Metric:1
	    [...]

Ie, I tried to shut down the eth0, but, should it be gone from "ifconfig -a"
output?

I tried to regain dhcp leases but that didn't help.

By then, I ran out of ideas so I rebooted. However, same things happened,
and I still can't get onto the Internet. 

Note that the Internet is working fine. The other machine that's using the
same router worked fine. Also, AOK when I boot back to Debian.

Please help. It's urgent. 

thanks
