[ale] Resolving

[Jason Lynn]

Thanks!  As for nsswitch.conf... I'll need to check that when I get home.  I 
do not wait for dns to timeout... after about 20 sec my patience grows thin. 
  :)  I will read that man page.  I know that I was definitely unable to 
ping (within 20 sec) my local interface eth0 with an ip of 192.168.0.1.  I 
thought it was strange also, but I suppose I could have my nsswitch 
misconfigured.  I'll try and wait for the timeout.
Thanks again,
Jason
