SUCCESS

In the following suggestions and hints, assume that your assigned fully-qualified hostname for your machine on the Salina SUCCESS LAN is "myhost.success.espo.nasa.gov", and your assigned IP address is 198.120.56.25. Consult the table of assigned hostnames and IP addresses to find your actual unique values for these two items and use them. The other configuration parameters for the SUCCESS LAN are shared by all hosts. They are:

  Netmask: 255.255.255.0

  Broadcast IP address: 198.120.56.255

  Gateway IP address: 198.120.56.1

  DNS Nameserver hosts:
    cloud4.success.espo.nasa.gov   198.120.56.130
    cloud1.arc.nasa.gov            128.102.154.176

Where to get NCSA Telnet for Macintoshes

Anonymous ftp site:  ftp.ncsa.uiuc.edu
Directory:           /Telnet/Mac/

Version 2.7 is the latest (and reportedly the final) Mac version of NCSA Telnet. We recommend version 2.6, because it includes a traditional ftp client, and v2.7 does not.

MacTCP

NCSA Telnet v2.6 (& v2.7) uses and requires the MacTCP software for basic level TCP/IP network support. MacTCP is distributed with many of the newer Mac operating systems. Be sure that you have MacTCP installed on your Mac if you intend to use NCSA Telnet v2.6.

Basic MacTCP configuration

To set up your MacTCP interface for use on the SUCCESS LAN at Salina:

• Select Control Panels (usually off the Apple menu)
• Select MacTCP
• Select Ethernet
• Select More
• Select Manually
• Select Class C type of network
• Select the Gateway box, & type 198.120.56.1
• Select the Net box, & type 13006904 (256*256*198 + 256*120 + 56)
• Select the Subnet box, & type 0 (no subnet on the SUCCESS LAN)
• Select the Node box, & type the last number in your assigned IP address, e.g. 25 in the example address
• Select the Domain Name Server boxes and add:
  • Domain: success.espo.nasa.gov IP: 198.120.56.130
  • Domain: arc.nasa.gov IP: 128.102.154.176
  • Domain: arc.nasa.gov IP: 128.102.18.31

Configuring options to NCSA Telnet for Macs

Beginning with v2.6 of NCSA Telnet for Macintoshes, there is no editable external config.tel file in which to specify the main options for telling the software how you want to conduct sessions.

Instead, the critical addresses and other TCP/IP network parameters are defined via MacTCP in control panel dialog boxes as described above.

Other options that pertain to the way the higher level NCSA Telnet program itself operates are chosen from selection dialog boxes that are available when the NCSA Telnet program is running on your Mac. These options are then saved in Mac preference files for future sessions. These options can be selected and saved separately for different remote hosts to which you might want to connect.

Since there are a large number of options from which to choose, it is probably best to consult the NCSA Telnet v2.6 documentation, chapter 2, to see the many possibilities and how to select them.

For security, if you are going to allow ftp transfers via your Mac's NCSA Telnet v2.6 ftp server, be sure to select the "FTP server mode on, with username and password required" option under the Edit/Preferences/FTP_server menu, and then assign specific user/password privileges under the Edit/Preferences/FTP_user menu. Otherwise, turn off ftp server capability to protect your Mac's files from unwanted connections from anywhere on the Internet.
