Client Configuration

BlueZone Emulator Configuration

BlueZone Mainframe, iSeries and VT emulators 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 OS/400 V4R4 or higher. 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.

BlueZone Mainframe or iSeries Configuration for SSL Security

Configure the telnet parameters:

1. Launch a BlueZone session and from the MenuBar 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 BlueZone MenuBar, select File:Save As.

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

• Configuration files named START.Z?? are automatically used by BlueZone to start every session configuring them identically the first time each session is run.

• Configuration files named Sx.Z?? (where x is the session number) automatically configures the Sx session only the first time the session is run.

• Configuration files named Sxlock.Z?? (where x is the session number) automatically loads the configuration file every time the Sx session is run, even when the Global Configuration Lock is on.

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