3270 and 5250 connection settings

In addition to the Common connection settings, 3270 and 5250 host types require these specific settings.

  • Terminal model

    Specify the terminal model (also known as a display station) you want Host Access for the Cloud to emulate. There are different terminal models available depending on the host type.

    If you choose Custom Model, you can set the number of columns and rows to customize the terminal model.

  • Use Kerberos automatic sign-on (5250 only)

    When set to Yes the user does not have to enter sign-on credentials. Kerberos automatic sign-on is configured in the MSS Administrative Console > Host Access for the Cloud. In configuring HACloud to use the Kerberos authentication protocol there are terms that you should understand and prerequisites to adhere to in advance of configuring this option. These options are explained in detail in the MSS Administrative Console > Host Access for the Cloud panel documentation, available from the Help button. See Set Up Kerberos for AS/400 Single Sign-on for more information.

  • Terminal ID (3270 only)

    When Host Access for the Cloud connects to a Telnet host, the Telnet protocol and the host negotiate a terminal ID to use during the initial Telnet connection. In general, this negotiation will result in the use of the correct terminal ID, and so you should leave this box empty.

  • TLS Security

    TLS protocols allow a client and server to establish a secure, encrypted connection over a public network. When you connect using TLS, Host Access for the Cloud authenticates the server before opening a session, and all data passed between and the host is encrypted using the selected encryption level. See Common Connection Settings for detailed information on this common setting.

  • Device name

    If you selected TN3270, TN3270E, or TN5250 as the protocol, specify the device name to use when the session connects to the host. The device name is also known as the host LU or pool. You can also choose to:

    • Generate a unique device name - Automatically generates a unique device name.

    • Use Terminal ID Manager - Displays additional settings to complete. See Using Terminal ID Manager

    • Always Prompt the User for ID - The end user is prompted for the device ID each time a connection is attempted.

    • Prompt the User if ID not Specified - The end user is prompted the first time a connection is attempted after which the value is saved. The saved value will continue to be used without additional prompting.

If you do not specify a device name for the session, the host dynamically assigns one to the session. A device name that is set within a macro will override this setting.
