Connecting to the Host SystemConnecting to the Host SystemThe BlueZone ICL emulator provides complete RFC1006 connectivity for BlueZone, allowing connection to hosts that are RFC1006 compliant. Optionally, Secure Sockets Layer security is available to insure privacy, message integrity and provide authentication.
RFC1006 configuration consists of the following tabs: Connections, Security, Certificate, Keep Alive, Trace, Firewall, and Security Server. To quickly "jump" to anyone of these subjects, click the desired link.
This dialog displays your Host Connection list and contains buttons for creating new connections as well as editing, removing and sorting them.
RFC 1006 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.
TCP Port: Specifies the TCP port number to which to connect. The default is 102.
Remote TSAP Port: Specifies the Remote TSAP port number to which to connect. The default is 0.
Local TSAP: Specifies the Local TSAP which to connect.
Remote TSAP: Specifies the Remote TSAP which to connect.
Backup Host: Specifies a second host connection if the first connection attempt fails.
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.
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.
Security Options ----
Enable Secure Sockets Layer: Specifies whether the TCP connection to the host should be encrypted using SSL.
Preferred Cipher Suite: If you have a preference, choose a Cipher Suite from the list box. Otherwise, leave it set to None.
Invalid Certificates ----
Specifies how to handle an invalid server certificate. Options include:
Always Reject: Specifies that an invalid server certificate should always be rejected.
Ask Before Accepting: Specifies that the user should be asked whether to accept an invalid server certificate.
Always Accept: Specifies that an invalid server certificate should always be accepted.
SSL Version ----
Specifies which version of the SSL protocol should be used. Options include:
SSL v3: (Default)- Specifies that SSL version 3 should be used.
TLS v1: Specifies that TLS version 1 should be used.
NOTE SSL
v3 and TLS v1 are nearly identical. TLS
v1 is preferred.
Client Certificate ----
These parameters specify the type of Client Certificate to use if any. Enable Secure Sockets Layer on the Security tab must be enabled in order for Client Certificate support to be active.
No Client Certificate: Specifies that a client certificate should not be presented.
Client Certificate in Disk File: Specifies that a client certificate should be presented.
Certificate File: Specifies the path to the Certificate File.
View: Use the View button to view the certificate.
Browse: Use the Browse button to locate the Certificate File.
Private Key File: Specifies the path to the Private Key File.
Browse: Use the browse button locate the Private Key File.
Client Certificate in Certificate Store: Specifies that a client certificate should be presented that is located in the Certificate Store.
Common Name: Specifies the path to the Common Name File.
View: Use the View button to view the certificate.
Browse: Use the browse button to display a list of certificates in the Certificate Store.
Client Certificate in Certificate on Smart Card: Specifies that a client certificate stored on a Smart Card should be presented. - Currently not implemented.
These parameters specify whether the client should send keep-alive messages to the server to keep the TN3270E session active.
Timer Options ----
Disable: Disables keep-alive messages. (Default)
Use NOP: Uses the Telnet NOP for keep-alive messages.
Use Timing Mark: Uses the Telnet Timing Mark (TM) for keep-alive messages.
Timer Value (Minutes): Specifies the time interval (in minutes) for sending keep-alive messages.
These parameters specify the interfaces to be traced and the file name to which the trace file will be written. The trace files are in ASCII text format and may be viewed with Note Pad or Word Pad.
STEP-BY-STEP
How
to Capture a BlueZone Trace
Trace Options ----
Trace Sockets Interface: Traces the data as it passes through the Winsock interface from the network connection.
Trace RUI Interface: Traces the data as it passes between the TN3270E driver and the BlueZone terminal session.
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.
View Trace: Used to view the trace. BlueZone will automatically use the Trace Viewer program specified above.
The Firewall tab allows the configuration of Firewall and Proxy Server sign on systems.
Firewall Options ----
Connect Through Firewall or Proxy Server: Check to enable this feature.
Firewall
Type: Choose the Firewall Type from the drop down listbox.
SOCKS4 Proxy
SOCKS4A Proxy
SOCKS5 Proxy
NVT Proxy or Firewall
HTTP Tunneling Proxy
Firewall Address: Enter the IP address of the Firewall. Can be DNS name or IP address.
Port: Enter the Port number used by the Firewall.
Timeout: Enter the appropriate Time out value.
User Name: Enter the appropriate User Name.
Password: Enter the appropriate Password.
Domain: Enter the appropriate Domain.
NOTE If
you have chosen NVT Proxy or Firewall, then you will need to provide the
following additional information:
Host Name Prompt: Enter Firewall of network prompts BlueZone should look for.
User Name Prompt: Enter the User Name that the Firewall is expecting.
Password Prompt: Enter the Password that the Firewall is expecting.
Connected Prompt: Enter the appropriate Connected message that the Firewall transmits.
The Security Server tab is used to configure BlueZone to use the Seagull Security Server as a Proxy Server to multiple hosts. This feature enables you to support connecting to multiple "back end" hosts through a single port in the Seagull Security Server while using HTTPS tunneling in BlueZone.
Security Server Options ----
Use Security Server to proxy to Multiple Hosts: Enable
Proxy Type: Choose the desired Proxy Type from the listbox.
Security Server Address: Enter the IP address of the Security Server.
Port: Enter the Port being used by the Security Server for these connections.
Timeout: The time (in seconds) after which, if a prompt from the Firewall has not been received, BlueZone will assume that the Firewall has been traversed and proceed with the next stage of the connection process. This is required for Firewalls which authenticate a user once but then do not re-authenticate on subsequent connections within a certain time period.
