Connecting to the host

To establish a connection to an enterprise server:

1. In the Rumba Mainframe Display view, click (New Rumba Mainframe Display). This TN3270 Connection Properties dialog box is displayed.

   

2. Type the name or IP address of the enterprise server and the TN3270 port number.
3. Optionally, type a unique name for the connection in the Terminal name field. (If you enter the name of an existing connection, you are prompted to change it.) If you do not specify a terminal name, the server connection is listed as ServerName:PortNumber - for example, localhost:5000.
4. If you are connecting to a secured server, select Enable TLS/SSL Connection[2], and then configure the TLS/SSL Settings section:
   • Enforce date validity - When selected, the connection process checks the expiry date of the server certificate, and rejects it if expired.
   • Require all issuers in the chain be trusted - When selected, the connection process checks if every certificate in the server's authentication chain can be trusted with a known CA certificate. This certificate must be stored in C:\Users\<user>\Documents\Micro Focus\RUMBA\Java\SSL\Server. If the file doesn't exist, Rumba prompts you to add the relevant CA certificate to this folder.
   • Match Hostname on the server certificate - When selected, the connection process checks if the hostname matches the server certificate, and shows a warning if it does not match. When this option is not selected, the connection will proceed without warning.
   • Certificate Information:
     • Client Certificate (.p12) - Click Browse and select the required client certificate. This can have one of the following extensions: .p12 and .pfx.
     • Private key password - If required, enter the required certificate password.
5. Click Connect.
