There appears to be no provision in Unix to restrict network access. DCA requires that hosts restrict network access to "authorized" users or these hosts themselves may be subject to restrictions on Arpa/Milnet mail bridge traffic. Is anyone out there doing this? How? Restricting the use of the network user-interface programs (ftp, telnet) would be quick and dirty but wouldn't keep someone who has his heart set on talking with the world from creating his own. -Bob Cattani, Columbia Univ.
