Chapter 6. TN3270 Client Definition Panel
Port
This is a five digit decimal number that defines the TCP Port that the server will listen
on for a TN3270 connection. This number must not be the same as one used for a Telnet
display in the Network Device Definition panel, LPD print server, or TCP print server.
IP Address
The IP address field is optional. If an address is entered, a TN3270 client connecting on
that TCP Port must reside at that IP address. If another entry contains the same resource,
such as in a 3270 Host Class, and a user requests a session from that class, the LU will
be given out to the requester.
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).
