POLARIS NETWORK SETUP FOR PC NCSA TELNET BOXES

Network Config hints for PC NCSA Telnet

NOTE:

IMPORTANT: Whenever making a change to a configuration file, always make a copy of the original version of the file that was working before you began reconfiguration.

In the following suggestions and hints, assume that your assigned fully-qualified hostname for your machine is "myhost.mf.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 are shared by all hosts. They are: 


Moffett Field

  Netmask: 255.255.255.0
  Broadcast IP address: 192.150.34.255
  Gateway IP address: 192.150.34.100

  DNS Nameserver hosts:
    cloud1.arc.nasa.gov   128.102.154.176
    mx.nsi.nasa.gov       128.102.18.31

Fort Wainwright

  Netmask: 255.255.255.0
  Broadcast IP address: 198.120.56.255
  Gateway IP address: 198.120.56.1

  DNS Nameserver hosts:
    cloud2.polaris.espo.nasa.gov   198.120.56.42
    cloud4.polaris.espo.nasa.gov   198.120.56.43

Barbers Point
 
  Netmask: 255.255.255.0
  Broadcast IP address: 198.120.15.255
  Gateway IP address: 198.120.15.1
 
  DNS Nameserver hosts:
    cloud4.polaris.espo.nasa.gov   198.120.15.43

Where to get NCSA Telnet for PCs 

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

Where to get packet drivers for various supported ethernet adapters

Define your assigned hostname in the config.tel file. The sample hostname of myhost is used here as an example, but you should use your assigned name. 

myname=myhost.mf.espo.nasa.gov

Define your assigned LAN IP address in the config.tel file. The sample IP address is used here as an example, but you should use your assigned IP address. 

myip=198.120.56.25

Define netmask, broadcast address, domain name, gateway (our router), and nameservers in the config.tel file. 

netmask=255.255.255.0

broadcast=198.120.56.255

domain="mf.espo.nasa.gov"

name=mf-gw;  hostip=198.120.56.1;  gateway=1;

name=cloud4; host=cloud4.mf.espo.nasa.gov; hostip=198.120.56.130;  nameserver=1;
name=cloud1; host=cloud1.arc.nasa.gov;          hostip=128.102.154.176; nameserver=2;
name=mxnsi;  host=mx.nsi.nasa.gov;              hostip=128.102.18.31;   nameserver=3;

For security, you should probably enable password protection, especially if you have enabled ftp with the "ftp=yes" option in the config.tel file. To enable password protection, include the option 

passfile="x"
in config.tel, with x being the full path to your password file. Password files can be created with the program telpass.exe, which is included with the NCSA distribution.

It should be noted that without password protection, anyone on the network can usually ftp to your PC while you are running NCSA Telnet and transfer files to or from your machine.

Static name to IP address table for LAN hosts

In case of nameserver failure, you should probably define your frequently contacted hosts' name vs IP address info in your config.tel file, plus the LAN hosts. A list of config.tel entries for the LAN hosts is under the "COMMUNICATION" top-level button.
