This should get triggered when a new IP address is negotiated.
Via DHCP, the ADSL 'modem' (D-link DSL-320T) passes it's wan IP address onto the client, and when it doesn't have one it gives you 192.168.1.2 with a 30 second lease so you get connected within that time when the link coming up, and if the link doesn't come up then your logs fill up instead.
Check the man page for pppd(8) and search for ip-up to see the details of how it's used, but just dropping scripts in those directories should be sufficient.
I wonder if it's possible to persuade the dhcp client to run a script? Thanks for you response.
