NokiaNetworkVoyager·Chapter4 155 Summary Nokia Network Voyager is a role-based application provided in a Web-based interface. You can use Nokia Network Voyager to manage your IPSO operating system on your Nokia appliance. The IPSO operating system software is included and is accessible using a Web browser from a client. All information appears in a navigation tree view, similar to Windows Explorer and is split across four frames. If you do not have access to a system item, then the item does not appear in the navigation tree. Read-only access gives you access to the page, but with the buttons disabled. Remember to not use the Back and Forward buttons of your Web browser while in Nokia Network Voyager because the browser caches the HTML page information and the latest page information might be lost when moving from page to page. When you set up your IPSO system for the first time, configure the basic Nokia Network Voyager options and change your SSL/TLS certificate from the default certificate. To secure Nokia Network Voyager client connections to the IPSO system over the Internet, IPSO uses the SSL/TLS protocol. When setting up your system for the first time, change your SSL/TLS certificate from the default certificate. IPSO includes a default sample certificate and private key in the /var/etc/voyager_ssl_server.crt and /var/etc/voyager_ssl_server.key files, respectively. IPSO uses the SSH program to provide secure connections for the CLI.
