The following topics are discussed: * About LiveUpdate * What's New * Running LiveUpdate * Updating LiveUpdate * Installing/Uninstalling LiveUpdate * Technical Information * Using AOL (America Online) * Using IBM Global Network * ISDN support * Known Issues ********************************************************************** ABOUT LIVEUPDATE ********************************************************************** LiveUpdate is the Symantec technology that permits an installed Symantec product to connect to a Symantec server automatically for program and virus definitions updates. The connection is made through either a preset telephone number or an Internet site. LiveUpdate can also be configured to use a local network server as bandwidth requires (for corporate customers). To do this, download the LiveUpdate Administration Utility at: ftp://ftp.symantec.com/public/english_us_canada/liveupdate/updates/luau.exe ********************************************************************** WHAT'S NEW ********************************************************************** LiveUpdate 1.5 has many new changes: One Button Update: LiveUpdate 1.5 now has the ability to retrieve and install updates for multiple Symantec products simultaneously. Many Symantec products released after February 1999 contain this feature. Download Resumption: LiveUpdate can resume interrupted transfers transparently. If you've ever had a download interrupted by call-waiting or internet problems, you'll appreciate this new feature. Download resumption is available for both the HTTP and Modem transports. It is not available for the FTP transport or for the LAN transport (corporate customers only). Proxy Servers: Most internet users don't need to configure their computers to use a proxy server, but we've made it easier then ever via a new Proxy tab in the LiveUpdate Control Panel. Note: If you do not know what a proxy server is, it may be best to set options using the Proxy tab only when instructed to do so by a network administrator. To configure LiveUpdate to use a proxy server, simply select the Proxy tab and put a checkmark in "Connect through a Proxy Server". By default, LiveUpdate will use your Internet Explorer Proxy Settings (if available), but you can easily specify your own custom settings for both FTP and HTTP. * Note: LiveUpdate now uses HTTP by default. If your proxy server requires authorization for outside access, you can also enter a Username and Password for either FTP or HTTP (or both) proxy access. Please note that this is different from the username and password you use to connect to your Internet Service Provider (if you use one). Certain networks are configured only to allow FTP to use a "passive connection". If you have difficulty using the FTP transport, check the box on the Internet tab of the LiveUpdate control panel labeled "Use Passive mode FTP transfers". If you have any difficulty configuring your proxy settings, contact your network administrator for assistance. Each network is different, so only they can help you with this step. ********************************************************************** RUNNING LIVEUPDATE ********************************************************************** Most Symantec products which use LiveUpdate offer a LiveUpdate button. In Norton SystemWorks, for example, you can run LiveUpdate from the SystemWorks Integrator. You can also run LiveUpdate from the LiveUpdate Control Panel. This will automatically download updates for all Symantec products which use our One Button Update technology (discussed above). ********************************************************************** UPDATING LIVEUPDATE ********************************************************************** Sometimes even the update program needs an update. LiveUpdate will automatically check to see if there are any available updates to itself each time it is run. It should update itself transparently (without any extra input), but in certain rare cases may require that you run LiveUpdate one additional time to complete your session after it has finished its update. If this is required, it will tell you. ********************************************************************** INSTALLING/UNINSTALLING LIVEUPDATE ********************************************************************** All Symantec products which use LiveUpdate install it themselves, but if you encounter a problem with LiveUpdate that you or Technical Support believe to be the result of an install problem or corrupted files, you can reinstall easily. To reinstall, locate LUSETUP.EXE on your system or download the latest version from the Internet at: ftp://ftp.symantec.com/public/english_us_canada/liveupdate/updates/ Once the file is on your system, double click the icon. You will be asked if you wish to install LiveUpdate. Answer yes, and it will automatically reinstall. Your previous settings will be saved, and you will still be able to run LiveUpdate from any Symantec product without further configuration. If you wish to uninstall LiveUpdate, please note that you will no longer be able to receive updates to your Symantec products. Your configuration information will also be removed so that when you reinstall, you may need to re-configure custom proxy settings or connection info. To uninstall LiveUpdate: 1. From the Start menu, select Settings > Control Panel. 2. Double-click Add/Remove Programs. 3. Select LiveUpdate from the list, then click Add/Remove. To reinstall LiveUpdate at any time, find the LUSETUP.EXE at the above URL and simply double-click it. ********************************************************************** TECHNICAL INFORMATION ********************************************************************** LiveUpdate uses four possible methods for retrieving updates and installing them. 1. HTTP We now use HTTP to download files from the Internet. This replaces FTP as our primary method for the following reasons. a: With the advent of the World-Wide-Web, HTTP is more widely used than FTP. More Internet Service Providers and corporations are configured to allow unrestricted HTTP transfers than FTP. This reduces the likelihood that you will need to configure LiveUpdate manually. b: Through switching to HTTP, LiveUpdate now offers Download Resumption via the Internet. If a LiveUpdate transfer is interrupted because of a severed connection to the internet (due to line noise or call waiting, for example) or merely cancelled, it can be continued the next time LiveUpdate is run. c: HTTP is slightly faster than FTP. Also, if the file that LiveUpdate uses to determine the availability of updates has not changed since the last time it was run, LiveUpdate can now detect it and avoid re-transferring it. This will make your LiveUpdate sessions faster than before. 2. FTP FTP is the backbone of file transfers on the Internet. If LiveUpdate is unable connect via HTTP, it will attempt to use the old FTP method automatically. FTP does not offer download resumption. Corporate customers may need to configure LiveUpdate to use an FTP proxy or to use FTP in passive mode (as discussed above), but the updates it downloads are identical to those retrieved via HTTP. 3. Modem For customers who do not have access to the Internet, we offer Modem transport. Using this, LiveUpdate can make a phone call to a computer near you (depending on your location). Note that if the call is outside your local dialing area, your long distance telephone service carrier may charge you for the call. If a modem download is cancelled or interrupted (by line noise or call waiting), it will resume the transfer the next time LiveUpdate is run. This feature is especially important in countries with unreliable phone service and should significantly reduce the amount of time spent downloading. 4. LAN (Local Area Network) Corporate customers may wish to create their own internal LiveUpdate servers to ease bandwidth usage. For more information on this, download the LiveUpdate Administration tool referenced earlier in this document. In addition to the previous three transports mentioned, corporate customers may configure a network server to provide the updates using a standard file copy operation. This may be faster and easier to configure than FTP or HTTP. More information about the LAN transport is available from within the LiveUpdate Administration Utility. ********************************************************************** USING AOL (America Online) ********************************************************************** If you are attempting to update your Symantec product using LiveUpdate and you have AOL installed you should take note of the following: If you are connecting to the Internet via your modem, LiveUpdate requires that a TCP/IP connection be established. If you have AOL installed, you need to first dial up to your local AOL access number and go on-line/login with your AOL account. You do not need to configure LiveUpdate settings in any way. Run LiveUpdate from the Control Panel Applet or from any of the Symantec Products that you have installed. Note that Symantec is not liable for any phone charges incurred when making this dial up connection. ********************************************************************** USING IBM GLOBAL NETWORK ********************************************************************** If you are already online with your IBM Global Network service you do not need to follow these instructions. The following information only applies if: 1) You wish to use an IBM Global Network to connect to the Internet 2) You are not on-line when a LiveUpdate session is started If you are using the IBM Global Network Dial-Up Networking client to establish an Internet connection to enable LiveUpdate to connect to the Symantec LiveUpdate servers, you are required to have the following settings: 1) From the Control Panel double-click on the LiveUpdate icon to open the LiveUpdate Settings Applet 2) Select the Internet tab 3) Enable "Connect to the Internet using a modem" 4) Within the "Use the Dial-Up Networking connection" select 'IBM Global Network' 5) Within the "User Name" field enter first the "Account" followed by either a period, "." or "\" and then the "User ID". Both the IBM Global Network Account and User ID should have been provided to you by IBM Global Network i.e. Username: myaccount.myusername Password: mypassword 6) In the "Password" field enter the password as provided to you by IBM Global Network ********************************************************************** ISDN SUPPORT ********************************************************************** For instructions on how to configure LiveUpdate to use your ISDN modem please visit the following URL (Note that these instructions only apply to our European customers): http://service1.symantec.com/SUPPORT/sharedtech.nsf/docid/1998120914534313 ********************************************************************** KNOWN ISSUES ********************************************************************** Connecting to a LiveUpdate server through a Proxy server that requires its own user name and password authorization requires Internet Explorer 4.x. ********************************************************************** END OF FILE **********************************************************************
