I just got mine working with the Tellstick the other day, and this is the configuration I found worked:
I have often wanted a way to check if end of life is getting close for my systems on the command line.
The message in freebsd-update is really nice, but it feels a bit overkill to run that just to check if I should consider updating to a new release of FreeBSD -and it also only checks for the system it is run on..
So I hacked up this little script which checks if EoL is close for either the currently running release of FreeBSD or for the one given as an argument. Now I can have a cron job running every now and then to check for all releases I’m using.
