1.28. Automatic update configuration
The SPECTRE router can be configured to automatically check for firmware updates
from an FTP site or a web server and update its firmware or configuration information. Use
the Automatic update menu to configure the automatic update settings. It is also possible
to update the configuration and firmware through the USB host connector of the router.
If the Enable automatic update of configuration option is selected, the router will
check if there is a configuration file on the remote server, and if the configuration in the file is
different than its current configuration, it will update its configuration to the new settings and
reboot. If the Enable automatic update of firmware option is checked, the router will look
for a new firmware file and update its firmware if necessary.
Item Description
Source Select the location of the update files:
HTTP/FTP server
– Remote file server.
USB flash drive - Router will check for firmware or configuration
files in the root directory of the connected USB device.
Both
– Router will check for new firmware or configuration files in
both places.
Base URL Base URL or IP address from which the configuration file will be
downloaded.
Unit ID Name of configuration. If the Unit ID of the router is not filled in, then the
MAC address of the router will be used as the default file name. (The
delimiter in a MAC address is a colon instead of a dot.)
Update Hour Automatic configuration update starts 5 minutes after turning on the router
and then every 24 hours at the Update Hour.
Table 60: 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 are added to
the file name
automatically and it isn‟t necessary to enter them. When using parameter Unit
ID, the hardware MAC address in the name will not be used.
The firmware file name is named parameter Base URL, type of router and bin
extension.
It is necessary to load both files (.bin and .ver) to the HTTP/FTP server. If only the
.bin file is uploaded and the HTTP server sends the incorrect answer of 200 OK (instead of
expected 404 Not Found) when the device tries to download the nonexistent .ver file, then
there is a risk that the router will download the .bin file over and over again.
