I just wrote some kind of proggy that allows the users of my BBS to establish SLIP connects.
Now, I would like to forbid to the guest users the acces to some services, like the SMTPd and NNTPd.
I saw that such a thing can be done by modifying the inet.acces file, but I would like to know if it can be done with some function call (in other words without having to modify the inet.access file).
Moreon I would like to limit to the guest users the access to my BBS machine, in other words they shouldn't be allowed to access the whole InterNet.
