I want to thank the following for their comments and suggestions:

Its not an issue with the /etc/hosts files, or nameserver. I suspect
something in the route tables, but I havent figured it out yet. If I
do, I will post a final summary.
For a temporary workaround, I just placed oakfp in the necessary .rhosts/.shosts
files, and the export file.
