Ping and traceroute not working on new potato install

Hi --

  I recently installed a machine with debian.  I only have one problem
with the install.. I can't ping.. whenever I try to ping:

<3 bleh:~ >ping 127.1
ping: socket: Protocol not supported

traceroute has this error also:

bleh:~# traceroute 127.1
traceroute: icmp socket: Protocol not supported

All other networking on this machine works fine. I can telnet, ssh,
web browse, etc.  I just can't ping or traceroute.  I'm baffled.  

Thanks, 

Michael Janssen
