Connecting to CNS by Modem

  1. 1. Connecting to CNS by Modem CNS Document ID: gbconnecting Last Updated: 06/24/2003 You can connect to CNS from almost anywhere that has a telephone line if you have a workstation (i.e., PC, Macintosh, etc.) and a modem. CNS provides dial-up servers for you to connect by modem. In addition to CNS's local dial-up modems, the Florida Information Resource Network (FIRN) provides local dial-up telephone numbers in many Florida cities for educators. Together, these services provide access to CNS host-based applications, other University of Florida host servers, and the whole Internet.

  3. 3. Connecting to CNS by Modem Connecting to CNS by Modem Note Users considering using the UF/CNS dial-up service should be aware that this service is under review, and may possibly be discontinued at or shortly after the end of calendar year 2006. For more information, please see Dr. Hoit's memo to Deans, Directors and Department Heads of 05/02/2006, titled Charging for UF Dialup Services [http://www.admin.ufl.edu/ddd/default.asp?doc=11.11.1920.1]. You can connect to CNS from almost anywhere that has a telephone line if you have a workstation (i.e., PC, Macintosh, etc.) and a modem. CNS provides dial-up servers for you to connect by modem. In addition to CNS's local dial-up modems, the Florida Information Resource Network (FIRN) provides local dial-up telephone numbers in many Florida cities for educators. Together, these services provide access to CNS host-based applications, other University of Florida host servers, and the whole Internet. For a connection to CNS host and telnet services, all you really need is a workstation, a modem, a telephone line, and communications software (e.g., Dial-up Networking or HyperTerminal that comes with Windows). You can also access CNS by dialing into a commercial Internet Service Provider (ISP) (e.g. AOL, BellSouth.Net, or EarthLink, etc.) and using telnet or TN3270 to connect to CNS (see Assessing CNS Systems). NOTE: Some services (for example, NETg training) may require you to use CNS's Virtual Private Network (VPN) when accessing them through a commercial ISP connection (see below). Dial-up Servers Connecting via modem to the dial-up servers is easy and allows access to all of our interactive systems such as AIX, CICS, TSO, the Internet and World Wide Web, and other University of Florida host servers. The dial-up servers support full Internet access via PPP (Point-to-Point Protocol) or SLIP (Serial Line Internet Protocol) using standard tools such as Windoows Dial-up Networking , or Macintosh Internet software. In order to use PPP or SLIP, you must supply your own workstation/microcomputer software, such as the Windows Dial-up Networking, or FreePPP. The dial-up servers support modems up to 56000 bps (V.92); MPP (Multi-link PPP) and ISDN are also available on a portion of the Dial-up Servers using a separate phone number. Modem Speeds The Dial-up Servers support high-speed modems. You can connect with speeds of 14400, 28800, or 56000 bits per second (bps) or with a 128K (ISDN) modem (check with your BellSouth provider for availability). Of course, if you connect using a modem that’s not as fast as CNS’s, the speed of your modem will limit how fast our modem can transfer data to you. ISDN, ADSL and cable modems are also available as higher speed alternatives, but are limited by your area. CNS directly supports ISDN. Check with your phone and/or cable provider for more information. Note: speeds below 14400 bps are not practical for full Internet (SLIP/PPP) access; however, character-only terminal emulation is available to support slower-speed 3
  4. 4. Connecting to CNS by Modem dial-ups. Virtual Private Network VPN is a set of technologies that allow us to build secure "virtual" networks between hosts on insecure networks. Our particular type of VPN is commonly known as a remote access or tunnel mode VPN. To use the VPN, you install software on you computer whcich makes a connection to a VPN concentrator and creates a secure tunnel from your machine to the UF campus network. Additionally, your machine will appear as if it were on the UF network (i.e., you get an IP address on the UF network). VPN is an important component in the wireless network access that iis being developed on campus. Without VPN on a wireless connection, the connection should not be considered secure. Support is provided by the UF Computing Help Desk (http://helpdesk.circa.ufl.edu). For more information, please see http://net-services.ufl.edu/vpn.
