Inadyn is a small and simple DDNS client used in many open source routers and gateways. It automates the task of keeping a DNS record up to date with a user’s dynamic IP address. It is the continuation of the original INADYN by Narcis Ilisei. The goal of this project is to entirely focus on *BSD, UN*X, and various embedded Linux platforms.
Pagekite is software to make servers on "localhost" visible to the wider Internet. It can be used by Web developers to show off their works in progress to clients or colleagues, embedded developers who need direct access to devices in the field, or as an alternative to dynamic DNS for individuals/hobbyists who would rather host their own content than rely on 3rd party hosting. It creates and maintains a tunnel between your server on localhost and a remote "front-end" (a reverse proxy). Only the front-end has to have a visible IP address; the server itself can reside on a heavily firewalled computer, a mobile device, or even an anonymous node on the Tor network.
