   I'd expect you to need more than two hosts ... ? But I don't know your   
   requirements.

   Assuming you really only need a handful of endpoints:   
      
   - All the normal command-line tools and scripting languages   
   - Its configurable IP stack   
   - Its firewall   
   - ...   
      
   The "normal tools" I'd use would include ping, netcat, wget, ssh and   
   rsync. And the TCP and UDP flavors of the 'echo' and 'chargen' services.   
      
   Maybe you want one single tool which gives you one simple answer instead.   
   Someone else will have to mention those -- I don't know them.
