Port Information

This panel allows you to specify a port number on which the TN3270 server will listen for client connections. Optionally, you can specify an associated link, which causes the TN3270 server to listen on the specified port, but only for connections that come in over the associated link.

You can indicate if the connections for the port should be secured using SSL or TLS technology. Typically, clients are within a secure intranet and additional security is not required. However, if your clients connect in from the internet outside of your firewall, you will likely want to protect your connections using SSL or TLS security. This includes encrypting and authenticating data delivery and possibly using client certificates to authenticate the clients.

Before you begin, know the port number, any desired link association, and whether security services are needed.

Steps

  1. Enter the port number
  2. Indicate if security functions are desired.
  3. Optionally, specify a network link for this port. Specify the link in the form of a link name or an IP address. Clicking Show links will display all currently defined links.

You have completed this panel after you have entered a port number and selected a connection type.
