Configuring TELNET Path Parameters

When you configure a path that uses the TELNET Service Library you will be asked to supply the following information:

Terminal Type

Select the appropriate terminal type: NVT, VT100, VT220, ANSI or Other. If you choose Other you should supply a name that will be used to identify the terminal type to the host at the other end of the connection.

Terminal Location

This should be a Host IP (internet) address (in dotted notation).

Remote Echo

If you select the Remote Echo option, characters typed at the keyboard will be echoed back from the remote computer instead of being displayed directly on the screen by your application. You should choose this option only if your application requires it, since it can add considerable overhead to your response time.

Binary

If you select the Binary option, your application will be able to transmit non-ASCII data without having it translated. Check your application's documentation to see if you need to set this option.

Authentication

If you select the Authentication option, your application will request a credential from the applications credential server and send the credential to the application server. If the credential is valid, your application will be logged in without the prompt of user ID and password. If not, user ID and password will be prompted. This option is for 32 bit Windows platforms only.

Before running your application with authentication option, you must acquire a Ticket Granting Ticket (TGT) from your Kerberos server. You need to specify forwardable flag when you do the TGT request if you need to forward a credential to your application host.

  1. Install Unisys Kerberos client software on workstation and

    1. Modify krb5.conf file to include CyberSafe Kerberos environment.

    2. Modify kdc.conf file to include CyberSafe Kerberos environment.

    3. Set the environment variable VRB5CCNAME to CyberSafe cache file path with FILE: preceding to the path.

      e.g. VRB5CCNAME = FILE:c:\csfc5\tmp\cc\krb5cc_GEORGE

  2. You can now use either CyberSafe Cred Manager or Unisys Kerberos client to acquire a TGT.When Authentication checkbox is checked, the Authentication Configuration dialogue appears.

Authentication Type

Currently only Kerberos version 5 is supported.

Options

Select Mutual Authentication if application servers credential is required.

Select Forward Credentials if a forwarded credential is needed by application server.

Choose OK to complete the configuration. Choose Cancel to ignore your changes.
