You can only ssh into onl03.arl.wustl.edu from outside of the
testbed.
You can only ssh into hosts other than onl03 that have been
commited to you; i.e., wait for the experiment commit to
finish first.

Are you pinging from the correct host; i.e., usually not onl03?
Are you pinging to the correct host?
Have you installed routes in both the forward and reverse directions?
(The brute force method: 'Topology ==> Generate default routes'
will generate default routes on all ports)
