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. -Bennett -- "Hypocrisy is the vaseline of social intercourse."
