Ping works, but fping and hobbitping do not work

[Eric Jacobs]

We've been using fping in Hobbit for connectivity testing for years. But an 
interesting problem has arisen. There is one address for which the 
connectivity test fails, but, from the network tester, I can manually ping 
the address, but a manual fping (or hobbitping) fails. Anyone have an idea 
why this would be the case?
