Chapter 5. TN3270 Client Definitions
707112-001
Type
This field determines how the IP address is to be interpreted, whether passwords are required,
and what type of client is allowed to connect. The options are:
• Client: A TN3270, TN3270E, or TN3287 client may attempt to connect. If an address
has been configured, only a client using that address will be allowed the connection.
LINCS handles any command chaining data streams for the client.
• Client PW: This is handled the same as a client request, except that the client will be
challenged for a password. Do not use this definition for a TN3287 client.
• VisaraNCT: This definition is only to be used with Visara 1783 and 1683 clients running
IL47 microcode or higher, or Visara 1883 clients. The TN3270 client function of a
downstream LINCS platform also uses this definition. No other device will successfully
negotiate the special command chaining option that this definition implies.
• VisaraNCT PW: This is handled the same as a console request, except that the client
will be challenged for a password.
• Subnet: When set for “Subnet” the address configured for this entry will be treated as
a subnet address, and only users connecting from that subnet will be permitted a
connection. If no address is configured, the entry will be ignored.
• Client ID: This entry requires the user to provide a User ID and Password to make the
connection. The User ID and Passwords are defined in the ‘nickname.sys’ file described
later. LINCS provides all Command Chaining sequence handling for the client, when
the session is a console session.
• Client+CC: This configuration requires the client to provide its own Command Chaining
datastream handling.
• Client+CC PW: Configuring this option requires the client to provide its own Command
Chaining datastream handling, and challenges the client for the configured Telnet
password (as configured in the LINCS configuration).
• Client+CC ID: When this entry is used, the client must provide its own Command
Chaining datastream handling, and the user must provide a valid User ID and password,
as described in the following section on the ‘nickname.sys’ file.
• VisaraNCT ID: This definition is restricted to TN3270 clients running on Visara NCTs
and other LINCS platforms. In this instance, the user must provide a valid User ID and
password when establishing their connection.
• Console: This configuration can be used if the session that is being assigned is always
to be a console session. The LINCS software will not attempt to determine the session
type, but will assume it to be a console session.
• Console PW: This configuration is the same as Console, but will challenge the client
for the configured password.
• Console ID: This configuration is the same as Console, but will challenge the user for
a User ID, followed by a Password prompt. The User ID and Password will be compared
to entries in the nickname file for validation.
• Nonconsole: This configuration can be used if the definition is for a VTAM application
session, and never as a console. The LINCS software will not attempt to determine the
session type, but will assume that it is not a console session.
