Hi = David,
Thanks for pinging me. Do you think I could login into the setup and
see what is happening?
I do have the credentials for two systems in your lab -
rhea.dpdklab.iol.unh.edu and io.dpdklab.iol.unh.edu
If you can provide me details of the systems you are trying to
configure, I could take a look.

Thanks
