How do I change the SSL port?

By default, your JumpBox is configured to listen for HTTPS connections on port 443, which is the standard HTTPS port. It is possible to change this using the following instructions:

• Ensure the JumpBox is running, with SSL and SSH enabled.
• Log in to the JumpBox using SSH.
• Edit the following files using sudo and the editor of your choice:
  • /etc/apache2/sites-available/default-ssl.off
  • /etc/apache2/sites-available/default-ssl.auto
  • /etc/apache2/sites-available/default-ssl.custom
• Chance each occurrence of "443" to the port of your choice and save each file.
• Restart Apache using the following command:

  /etc/init.d/apache2 restart

• The JumpBox should now be available via SSL on the port you chose.
