You've tried to ping a tuple for which there is no route. You probably
mean:

  dtnping bundles://internet/host://piquet.jhuapl.edu/

FYI -- you can run the daemon with -l debug to get a bunch more
debugging output. Also, there are useful console commands such as
'bundle list' and 'route dump' which can help in diagnostics.

-m
