Reference:Configuration/General/Update

On this page the device can be configured to poll an update server (a normal web server). The file configure with the URL is read from the update server and executed. This is an efficient mechanism to keep a large number of devices up to date. See Howto:Update Server for a detailed description of the available commands.

URL

An URL, for example http://192.168.0.1/update/script-ip800.txt, pointing to a file whose commands are executed. If the URL ends with a slash '/', for example http://192.168.0.1/update/, the device is adding the file name update-ipxxx.htm automatically, deduced from the device short name (for example update-ip800.htm). Furthermore some placeholders may be used in the URL-String as described in the update servers scfg command description. These placeholders may be used e.g. to address a device-specific directory (http://192.168.1.2/update/#h/script.txt) or to generate HTTP-GET parameters (http://192.168.0.1/update/script.php?mac=#m). Some standard parameters are always appended to the query part of the URL: name value example ver human readable version information (as shown in the Version' line of the general page (display, for programmatic use rather apply #F etc.) 6.00 dvl-sr1 IP6000[07-60600.03], Bootcode[145], HW[104] 16384/131072 BOOT last tag for boot command 336 CHECK last tag for check command 20070511-01 PROT last tag for prot command 07-6060003 BMC last tag for bmc command If access to the command file requires authentication it must be configured within the HTTP-Client of the device. See Configuration/General/HTTP-Client.

Interval

An interval (in minutes) at which the file is re-read and executed. To restrict the update to certain hours (e.g. only during the night), there are mechanisms within the available commands to restrict the execution of the commands. The polling of the command file cannot be restrcited.
