adsl.sh is a Bash script to easily manage an ADSL pptp connection (most French "France Telecom" ADSL equipment uses this). It's pre-configured for this kind of connection, but you can easily edit the script to make it suit your needs. It can also update your IP adress on dhs.org and/or dyndns.org, and gracefully restart Apache (if you use VirtualHosts, it's mandatory when IP changes).
