ping is not installed by default (it is gotten like apt-get install iputils-ping)

or tests need to be updated to skip on this platform -- or skip the tests if none of /bin/ping / /sbin/ping /usr/bin/ping exist.

I think it would be nice to add that package so we can run the tests. That should be easy IMHO as we own the images.

@ulisesh could you also install ping in all the helix images?

[ulisesh]

Sure, I will add ping to out helix images

BTW we had some dependencies for dumplinks to work.
Did we verify that it works and we can get stack traces?
(depends on Python and lldb, maybe more)

seems to be fixed now. closing.
