UULINK is distinctly steep for a RBBS system; I think it is also very
reasonably priced for an MS-DOS implementation of UUCP/netmail/netnews.
The remote login capability is, according to Lauren, not intended for
secure multi-user access, but just to allow you to check mail from home.
I wanted to be able to give others logins for mail, and wrote a
restricted shell. Since the login program can be a .BAT file (use
REMOTE.BAT as a template) and you can start up whatever program you
like, write a trivial shell that only allows whatever commands you want.
I can give you mine of you like. Lauren isn't too interested in trying
to go too far with secure remote login, since the MS-DOS EXEC() code has
timing window bugs, and DOS's process structure doesn't allow much short
of a reboot to prevent a program from changing the resulting run-time
environment.
