Set up a SOCKS or HTTP Proxy Server Session

You can configure sessions to connect through a SOCKS proxy server or an HTTP server.

note

SOCKS and HTTP are supported for VT, IBM 3270, and IBM 5250 terminals.

Before you start

Make sure your system has a proxy server or servers and that you know the following information:

  • If you are setting up a connection to a SOCKS server, know the proxy server address and protocol version.

  • If you are setting up a connection to an HTTP server, know the proxy server address and port.

To set up a session to connect through a SOCKS proxy server or an SSL/TLS server

  1. Open the Create New Document dialog box.

    The steps depend on your user interface mode.

    User Interface Mode Steps
    Ribbon or Reflection Browser From the Quick Access Toolbar, click the New Document button.
    TouchUX Tap the Folder icon and then under File, select New.

  2. From the Create New Document dialog box, select a document template and click Create.

  3. In the Create New Terminal Document dialog box, under Connection, enter the Host name/IP address.

  4. Click Configure additional settings and then click OK.

  5. In the Settings dialog box, in the Host Connection section, click Setup Connection Security.

  6. If you are configuring a 3270 or 5250 terminal session, in the Configure Advanced Connection Settings dialog box, Under Security, click Security Settings.

  7. From the Security Properties dialog box, select the Proxy section.

    Select Use proxy server and then select whether to use the SOCKS or HTTP proxy type.

  8. Click Configure.

  9. If you want to designate only one HTTP proxy server, configure the session for the proxy server as follows:

    To configure… Do this
    SOCKS Enter the Server address and the Protocol version.
    HTTP Enter the server Address and Port.

    If you want to use authentication that requires a user name and password, select Basic authentication and enter the user name for the proxy server. (If this is not selected, no authentication is used.)

If you have trouble with HTTP timeouts, you can prevent them from occurring by configuring your proxy server so that it doesn’t timeout. For IBM 3270 and IBM 5250 sessions, you can use another approach to keep sessions alive as shown below.

To keep sessions alive to prevent HTTP timeouts

  1. In the Settings dialog box, under Host Connection, click Setup Connection Security.

  2. In the Configure Advanced Connection Settings dialog box, Under Keep Alive, select Keep Alive Packets.

  3. In the list under Keep Alive, select Send Timing Mark Packets.

  4. Change the Keep alive timeout in seconds interval to a value that is less than the HTTP proxy timeout.
