Had no luck with this on webdesign-l. Y'all have any thoughts? -BEN -------- Original Message -------- >> Anyone know what software exists to provide dynamic dns hosting (y'know, >> like ods.org or dyndns.org)? Web searches just show me a ton of >> providers. I guess I didn't phrase my question well enough. I'm looking for software to *provide* dynamic service. My understanding of how this works is that a client program sends a sort of "authenticated ping" periodically to the server, which checks the client IP address against Apache's DNS records & makes changes if necessary. I feel like this is probably more complex than it seems, though, and if turnkey or (ideally) open-source scripts existed to set up a server in this manner, I'd love to know about it.
