nspamper is an event driven client to update dynamic DNS entries via Nsupdates. It robustly copes with network problems by retrying until DNS returns the the new IP address. It also correctly handles the case where the link dropped and re-established before the last attempt succeeded by using the latest IP address. Only a minimum of configuration options are required.
Release Notes: The documentation was updated massively to reflect public status. The hardcoded settings became configurable. Fallback for IP changes while the nspamper daemon isn't running was moved into nspamper-change.
Release Notes: The init/ppp scripts were adjusted to remember the IP address when the nspamper client daemon is down.
