Secure FTP Transmissions Using SSH

In Distributed NetBeans, securing the FTP connection to the OpenVMS server requires SSH tunneling.  SSH tunneling is a way to forward unsecure TCP/IP traffic through the secure channel between the client and the server.

The SSH server software is included in HP TCP/IP Services for OpenVMS.  (HP recommends TCP/IP Services for OpenVMS Version 5.4 with ECO V5 or later, or Version 5.5 with ECO V1 or later.)

The SSH client software is not included with the Distributed NetBeans client. However, if the SSH tunnel is already established in the client machine where Distributed NetBeans is running, you can set the Distributed NetBeans connection properties so that the FTP port is forwarded to the SSH tunnel.

   To secure the FTP connection in Distributed NetBeans, perform the following steps:

–  Enable and start the SSH server in the OpenVMS server.

–  Create an SSH tunnel using the SSH client software on the client machine.

–  On the FTP filesystem mount wizard page, check the Use SSH forwarding checkbox and specify the secure port number used in the SSH tunnel.

 

 

The Distributed NetBeans client is tested on SSH Secure Shell 3.2.9 from SSH Communications Security Corp, and SecureFX 3.0.1 from Van Dyke Technology.  Both of these are available for the Windows platform.
