2 Linux Operating System Support Course Navigation for Local Installation on a Workstation/PC Select the download package (Windows or Linux zip file) that corresponds to your server/workstation operating system When possible, configure the content to be delivered through a local Web server when presenting to a class or over an academy LAN When installing the course on a standalone workstation or PC, please be aware of the following: o Disable all popup blocker software, toolbars, and applications o o Accept any ActiveX warning messages when viewing course content Navigate within the course window to avoid ActiveX pop-ups that can be generated by certain combinations of operating systems and browsers This course uses the latest features in Flash technology. An installer was used to aid in the local deployment of this product to Windows users. However, for Linux users, the Flash Player security settings must be set manually to run the course through a browser on a local workstation/pc. Installing a standalone curriculum on a Linux operating system requires additional steps after unzipping the course to the file system. After the course is unzipped, visit the Macromedia s security settings page at: er04.html After the page loads, some security options will be displayed. Verify that Always ask is selected. In the drop-down menu, select Add location, and then browse for the course folder. After the directory has been marked as secure, close all browser windows. Navigate to the course folder and click the index.html file to launch the course.

To stop the information bar from blocking file and software downloads for Mozilla Firefox, we recommend the following steps: To access the Popup Blocker Options, select Tools > Options > Content. From there, you can do the following things: o Block pop-up windows: Deselect this option to disable the popup blocker altogether. o Exceptions: Use this option to specify which sites can display popups. You can allow or remove sites from the list. Packet Tracer Evaluation Feedback Due to the evaluative nature of Packet Tracer activity files, all course activities have a Check Results button that submits the student s work for evaluation, and provides feedback. This includes observational activities that do not involve any configuration tasks. Packet Tracer files are evaluated by comparing the network submitted by a student to an answer network. All contents are Copyright 2009 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 2 of 2

3 Activities that require students to perform configurations have a default feedback message that states: This activity is incomplete, please try again. This message will appear until all configuration tasks are properly completed. Accessible Format Response Time Accessible Media Text Descriptions Accessible Theme Toggle Issue Accessible Theme Glossary Accessible Theme Dropdown Menu Accessible Theme Graphics Accessible User Guide For activities that require observation only, the state of the network will not change. If the Check Results button is selected, the feedback will say: Congratulations on completing this activity, even though the activity may not be completed. If this occurs, the student should finish all of the instructions in the observation activity to complete it. If a user is experiencing slow response times using course or chapter views, they should switch to viewing the content by page view. The slow response time is caused when a very large amount of data is saved in the browser s memory. The media text descriptions were tested using the Freedom Scientific JAWS 9.0 computer screen reader. For additional information regarding implementation of the JAWS 9.0 Screen Reader visit If you click the Toggle Language to English link to view the English version, then click the toggle language link again to view the previous version, the two navigation links (back/next) at the bottom will not work correctly. In the accessible theme glossary, codes appear in the definitions of some terms. Variable codes appear in the accessible theme content window dropdown menu. in the Chinese, Japanese, and Korean course versions. Dropdown menus within a graphic do not work in the accessible theme course versions. A user guide to the accessible version of the curricula is available from a link titled Open User Guide in a new window at the top of the launch page. Updates and Fixes This maintenance release includes the following fixes that address issues reported to the Global Support Desk: Section Reported Issue/Error Solution One quarter of the way into the Flash Animation: The current animation shows the source IP being looked up in the routing table.
