I do not have an adsl connection, but a ppp dialup, but some of the solutions I use here may be applicable:
The system I use is run from .etc/ppp/ip-up.local, a file that is run automatically when a ppp connection comes up - there are also network scripts that run when other interfaces come online: 1) The file contains $IPLOCAL and $IPREMOTE variables already set via the network scripts (by parsing ifconfig results I think) 2) uses the info to change the IP at dyndns and ods via ez-ipupdate. 3) creates a simple web page containing date/time and IP numbers and ftp's it up to my webspace on the ISP's server. 4) kicks ntpd which since 8.1 occaisionally hangs and refuses to recognise a new connection 5) restarts the firewall with the latest IP 6) same with named - not strictly neccessary, but solved some undefined, not quite working right type problems if you know what I mean!! 7) sends a smb message (winpopup) to the windoze machines attached telling them the connection is back up. A similar script in ip-down.local tells them when the ISP logs the connection off (kicker) 8) Recently I added some stuff to separate the ISP ppp connection and my laptop using another ppp connection through a serial port on the same machine. >From experience, I have found the redundancy of two dynamic dns systems and a separate web page is well worth while!
