Jose,

As far as I know, the person who wrote gssm is not on this mailing list.
I would suggest that you either contact that person, or figure out how
to update the code so that it runs with the latest version of GR.

I don't know how much experience you have with free software projects,
but in general, the people who want things working, make them work.
You appear to be a person who wants gssm working, thus you are the
_perfect_ person to sort it out.

Have your tried googling "TUNSETIFF: Device or resource busy"
Have you looked at the tap/tun documentation?
Have you looked at our current code and located any examples that use
tap/tun?  find and grep are your friend.
