3.8 Managing Listen Ports

You can direct Apache to listen to only specific IP addresses or ports; by default it responds to requests on all IP addresses. This directive is required. If it is not in the httpd.conf file, the server fails to start.

You can specify multiple ports. If you do so, Apache responds to requests from any of the listed addresses and ports.

Listen Ports page

To specify a new port number:

  1. On the Listen Ports page, specify the IP address, followed by a colon (:), followed by a port number.

    For example:

    
172.16.5.18:2003

    IMPORTANT:Be sure to verify that the port number you use is not already in use by another service. One way to verify what ports are in use is through NetWare Remote Manager. You can access it through the administrator's version of the NetWare Welcome Web site. At the site, click Remote Manager under Server Management. When Remote Manager starts, click IP Address Management under Manage Server.

  2. Under Encryption, click On if you want to use Secure Sockets Layer (SSL) with the newly specified port number.

  3. If necessary, select an alternate server certificate from the Server Certificates drop-down list.

  4. Click Save > Save to save your changes.
