Does anyone know where I can get a copy of the S/Key reference
implementation, as referenced in RFC 1760? The Bellcore address
no longer works and I have not been successful at finding an up to
date address.

I suppose I could simply consult the implementation in one of the
free Unixes but I'd rather go with a known quantity (minus any OS
specific 'enhancements') if at all possible.
