8.25 Automatic update configuration
In the window Automatic update it is possible to set automatic configuration update. This
choice enables that the router automatically downloads the configuration and the newest
firmware from the server itself. The configuration and firmware are stores on the server. To
prevent possible manipulation of the update, downloaded file (tar.gz format) is controlled. At
first, format of the downloaded file is checked. Then there is controlled type of architecture and
each file in the archive (tar.gz file).
By Enable automatic update of configuration it is possible to enable automatic configuration
update and by Enable automatic update of firmware it is possible to enable firmware update.
Item Description
Base URL By parameter Base URL it is possible to enter base part of the domain
or IP address, from which the configuration file will be downloaded.
Unit ID Name of configuration. If the Unit ID is not filled, then as the file name
used the MAC address of the router. (The delimiter is a colon is used
instead of a dot.)
Update Hour Use this item to set the hour (range 1-24) in which automatic update will
be performed every day. If the time is not specified, automatic update
is performed five minutes after turning on the router and then every
24 hours. In the event of a different configuration at the specified URL
router downloads this configuration and restarts itself.
Table 57: Automatic update configuration
The configuration file name is from parameter Base URL , hardware MAC address of ETH0
interface and
cfg
extension. Hardware MAC address and
cfg
extension is connected automat-
ically and it isn’t needed to enter this. By parameter Unit ID enabled it defines the concrete
configuration name which will be download to the router. When using parameter Unit ID ,
hardware MAC address in configuration name will not be used.
The firmware file name is from parameter Base URL , type of router and bin extension.
It is necessary to load two files (.bin and .ver) to the HTTP/FTP server. If there is uploaded
only the .bin file and the HTTP server send wrong answer
200 OK
(instead of expected
404
Not Found ) when the device try to download the nonexistent .ver file, then there is a high risk
that the router will download the .bin file over and over again.
