UCI, like other organizations, is experiencing an increase in illegitimate use of the network, particularly with the intent of gaining unauthorized access to campus computer systems. Some of these attempts to gain unauthorized access have come from systems that do not have hostnames registered in the Domain Name System (DNS). It has always been campus policy that systems connected to the campus network have registered hostnames.
On June 16, 1997, NACS systems and services will no longer accept connections from computers that are not registered in DNS. Effected NACS services include the EA systems, Orion, E4E, the HP Exemplar SPP2000, the campus FTP server (ftp.uci.edu), the UCI home page server, and Usenet News. These systems will not accept incoming telnet, ftp, pop (for Eudora) or Usenet news connections from hosts that are not registered.
Most users of NACS systems and services should not be affected by this change. If you receive a message stating that your system is not registered, please contact your Computing Support Coordinator (CSC) for help. If you do not know who your CSC is, or need further help, please call NACS Electronic Communications Services at x2222.
You may also register your system by filling out the form at: http://www.nacs.uci.edu/communication/ip_address_app.html
If you are connecting to NACS systems from an outside ISP, you will need to talk to the ISP help/trouble staff to resolve the problem.
