Connecting to the Host SystemConnecting to the Host SystemThe RTN5250E.DLL file provides complete TN5250E connectivity for BlueZone allowing connection to hosts, servers, and gateways that are TN5250E compliant. TN5250E is the enhanced version of TN5250, providing more SNA information to the client for improved operation. Optionally, Secure Sockets Layer security is available to insure privacy, message integrity and provide authentication.
TN5250E configuration consists of the following tabs: Connections, Display, (Printer), Security, Certificate, Keep Alive, Trace, Firewall, Security Server and About. To quickly "jump" to anyone of these subjects, click the desired link.
NOTE The TN5250E settings for the BlueZone Display emulator are identical to the BlueZone Printer emulator with the exception that the BlueZone Display has a Display Tab, and the BlueZone Printer emulator has a Printer Tab.
This dialog displays your Host Connection list and contains buttons for creating new connections as well as editing, removing and sorting them.
TN5250/TN5250E Connections ----
Connection List: This is a list of your configured hosts (if any). A total of 32 connections may be specified.
New: Used to create new host sessions. When clicked, the Define New Connection dialog box will appear.
Connection Name: A unique name used to identify the collection of Connection settings.
Host Address: Specifies the computer name (in Internet format, known as DNS Name) or the IP address (in dotted decimal format) of the TN5250E server. An IP address is the preferred format, eliminating the requirement for domain name resolution, resulting in a faster connection time and recovery if the name cannot be resolved.
Device Name: Specifies the name of the device to which to connect.
SEE How
to Automatically Generate Device Names for more information.
TCP Port: Specifies the TCP port number to which to connect. The default is 23.
Backup Host: Specifies a second host connection if the first connection attempt fails.
Enable TN5250E: Enables the TN5250E extensions. The default is enabled. This option should not be changed due to the fact that all iSeries printing must be TN5250E.
Connection Timer: Specifies the maximum amount of time (in seconds) to wait for the TN connection to complete.
Bypass Firewall: If enabled, individual connections can bypass the global firewall settings and connect directly to the host
Edit: Used to edit existing host connections that appear in the Connection List.
Remove: Used to remove existing host connections from the Connection List.
Sort: Used to sort the Connection List into alphabetical order.
Use Connection Name as Session Description: If checked, the name that you gave to the active connection, will appear in the BlueZone Title bar, immediately after the session number. This feature is handy if you have multiple hosts defined, and you are not using the "Connections" drop down list, and you want to know the name of the current connection.
TN5250E Display Properties ----
This feature allows you to override the following host properties in effect making a custom terminal definition from the client side of the connection:
Keyboard Type: Enter the desired Keyboard Type.
Code Page: Enter the desired Code Page.
Character Set: Enter the desired Character Set.
TN5250E Signon Information ----
This feature is called Encrypted Substitute Password. This feature is enabled on the iSeries (by the iSeries Administrator) by setting QRMTSGN to *Verify. It is used when you want to make the sign on process easier or to provide public access to an iSeries host where it is not desirable or necessary to have end users enter a User Name and Password to gain access. Also, you can call a specific Program, Menu and Library if desired. This is optional.
Force Encrypted Signon: As an option, you can "force" an encrypted sign on by presenting end users with a User Name and Password Dialog Box.
CAUTION! If
the sign on bypass fails or the end user signs off, the main iSeries log
on screen will be presented. This
will defeat the purpose of Encrypted
Substitute Password because the end user will be able to sign on
and send their password in the clear. To
prevent this, an "exit" program should be used so that if an
end user signs off, the iSeries will automatically force BlueZone to disconnect
from the host.
User Name: Enter the desired User Name.
Password: Enter the desired Password.
Program to Call: Enter the desired program to call. (Optional)
Initial Menu: Enter the desired Initial Menu to display. (Optional)
Current Library: Enter the desired Library to use. (Optional)

All BlueZone emulator clients support the SSL protocol through the SEAGULL Security Server or any SSL enabled telnet connection including IBM Communications Server for NT (SSL v3 only), OS/390, and the iSeries V4R4. BlueZone clients may be pre-configured for distribution with SSL enabled eliminating the need for any End-User intervention in the installation or configuration of BlueZone.

Trace SSL Connection: Traces the data as it passes through the Secure Sockets Layer component of the TN3270E driver.
Trace File: Specifies the file name to which the trace file will be written.
Browse: Displays a dialog used to select the directory and file name. BlueZone provides a Traces directory in the BlueZone installation directory.
CAUTION! This
must be a valid path or the trace feature will not work.
Trace Viewer: Specifies the program that will be used to read the trace file after it has been captured and written.
Browse: Displays a dialog used to select the directory and file name.
Start Trace: Used to manually start the trace.
Stop Trace: Used to stop the trace.

This is required for Firewalls which authenticate a user once but then do not re-authenticate on subsequent connections within a certain time period.
This tab is used to display information about the encryption technology used by BlueZone.
