Subject: [smokeping-users] Can't seem to find how to monitor DSL lines with
 dynamic IP assignemnt
Message-ID: <20170602115507.cxwa3n2h4534vakx@charite.de>

I remember that smokeping was - back in the days - designed to monitor
DSL lines with dynamic IP assigment.

Tobi had some mechanism that could RELIABLY detect if the machine
answering the probes was actually the machine behind the DSL line. But
i can't seem to find this anymore. How is it doen?

Hi Ralf

you had to run a little script on your 'home' box which would request a url on the smokeping site and from that smokeping would learn the ip 
it then also could do an snmp query of the target to see if the router there gave the right answer

with the advent of dyndns and frinends this feature has not been used much, but I think the code is still there

cheers
