BlueZone Client Configuration

BlueZone clients for TN3270, TN5250, and VT220 support the SSL protocol through the SEAGULL Security Server and any SSL enabled telnet connection including IBM Communications Server for NT (SSL V3 only), OS/390, and the AS/400 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 process.

See the BlueZone on-line help at www.seagullsw.com/help for additional details about configuring and distributing BlueZone.

To configure a BlueZone TN3270 or TN5250 connection for SSL security:

Configure the telnet parameters:

  1. Open a BlueZone session and go to Session::Configure.

  2. Select TN3270 or TN5250 from the Connection Type: list box and click the Configure... button.

  3. Select New...

  4. Enter a Connection Name: to identify the connection as a secure connection.

  5. Enter the Host Address: for the SEAGULL Security Server or the SSL enabled host.

  6. Enter the TCP Port: on which the SSL server is listening. Port 992 is the default for the IBM Communications Servers. Any port above 1024 may be configured in the SEAGULL Security Server.

  7. Select a Backup Host: if one is configured.

  8. Click the OK button to apply the settings and return to the Session Configuration property sheet.

Configure the Security parameters:

  1. Select the Security Tab and check the Enable Secure Sockets Layer check box.

  2. Select the appropriate method for handling Invalid Certificates.

  3. Select the SSL Version. SSL v3 and TLS v1 are nearly identical and the most secure. SSL v2 is provided for backward compatibility with older systems and is less secure.

  4. If client certificates are to be used, select the Use Client Certificates check box and provide the paths and filenames for the Certificate File and Private Key File. Note: PKCS12 certificates contain the certificate and private key in a single file, therefore, only the Certificate File name must be specified.

  5. Click the OK button to apply the changes and exit to the Session Configuration dialog.

  6. Click the OK button to return to the BlueZone Display or Printer window.

Save the SSL and all other configuration parameters to a file for distribution:

  1. From the menu bar, select File:Save As.

  2. Assign a name for the file in the File Name: edit box and click the Save button.

  3. Copy the configuration file to the BlueZone distribution image disk or directory. Used with Quiet Mode, or BlueZone Web, no user intervention is required to install or configure BlueZone.
