Upgrade to Debian testing hosed my system

> "ping beagle" returns the correct IP
The name resolution is done at the /etc/hosts or DNS server level, it has 
nothing to do the 'correct box' having the 'correct IP'.
Or being duplicated... 

The only way to detect a duplicate IP is by capturing packets and checking 
the MAC address.   If you knew the MAC address of the box, you can use 
'arping' to validate it.  'arping' also has a switch to detect duplicate 
addresses, but I'm not familiar with the functionality.
