You need modify httpd configuration for online documents and icons.

ViewCVS package has online documents and icons in /usr/share/viewcvs/ If you want to use it, you should modify configuration file of httpd (/etc/apache/httpd.conf or so) like, Alias /viewcvs/ /usr/share/viewcvs/ In addition, default templates use icons as /viewcvs/icons/*, so this configuration is required.

You can access viewcvs add: http://localhost/cgi-bin/viewcvs.cgi
