Netlanders,
	Is there a way to prevent a selected user(s) from TELNETing to other hosts once s/he has TELNETed in? I would like to be able limit TCP/IP services in
general to particular users depending upon the subnet from where they came. Things like secure inetd work with incoming connections, but is there anything I canuse to limit outgoing connections based on where the call originated?

				Thanks in advance,
