something i'm curious about ... if i set up an openwrt router, and
want to have it managed centrally, one of the things i'd like is the
ability to be notified of firmware upgrades.
a trivial solution is just to run a cron job that queries the
central administrator for newer firmware, lets the router admin
know about the new firmware, asks whether to upgrade, etc. that's
easy.
but to get fancier, rather than polling a central site, configure
the local router to receive notification only when new firmware is
available and avoid the trouble of regular polling. and what about
supporting different categories of upgrades -- "optional" versus
"critical/security", and so on, the ability to select which types
of upgrades are optional versus which are mandatory and will be
done without human intervention, and so on.
i poked around the openwrt wiki but didn't notice anything --
has anyone already done this? am i overthinking this? thanks.
Well, if you are sticking with official releases, there is only new firmware
when there is a new release.
If you are compiling your own or working from the nightly builds, there are
almost always changes, the question then becomes, are there changes for the
packages that you have installed on your router. That's a harder thing to check
for. the opkg command can query for new version numbers, but it's far from clear
that you should install them (due to the space issues on devices)
