Opening Ports

iCR for Java uses a browser interface to interact with the Navigator and the Reviewer. It may be that the host system for the service is behind a firewall or has security restrictions applied to it to limit network access. For the service to run correctly, a number of TCP ports must be open to the server. Some of these ports may already be open as they allow, for example, remote logins over SSH or other browser access. A couple of the ports are unique to iCR for Java. The ports that you need to have open are the following TCP ports:

1. 22 – This is the SSH port to allow you to access your server. You use this to securely login into your host system to be able to run the iCR for Java commands.

2. 80 – This is the regular HTTP port to allow browsers to access your server.

3. 443 – This is the secure HTTPS port to allow browsers to access your server.

4. 3001 – This port is used by your Browser to work with the Navigator and Reviewer.
