Introducing DNS Agent

Category : Technology

For a long time, I've been wanting to replace DNSUpdate with my own app (DNSUpdate had been keeping my server's IP address record on dyndns.com updated in sync with my domain name whenever that IP address changes).

Ever since the Work Around Bonjour troubles we've had on OS X 10.4.7, DNSUpdate hadn't been working quite right, always stalling when you try to install its IP-monitoring daemon, and even now on Snow Leopard.

So building something to replace it had been on my radar for some time. And the time came when I received a request to add dynamic DNS client support to DNS Enabler Snow. I worked on this over the last couple of months and I have now a new version of DNS Enabler Snow to release, which I'll do next, but first I'll introduce its companion app, DNS Agent :

DNS Agent can update a DNS Enabler Snow-enabled DNS Server with a client's ever-changing IP address (i.e., those machines on dynamically assigned IP addresses or those machines always on the move), as shown above.

Or, DNS Agent can update dyndns.com, if the user has a member's account with dyndns.com (see below).

Setting it up to use with dyndns.com is dead easy - just enter your members.dyndns.com userID and password by clicking on "Set Up Update Keys" button, enter the host name(s) of the machine for which you want DNS Agent to update dyndns.com, start the IP-address monitoring daemon, and you're good to go (as shown above). You can then close the app because the daemon continues to run, even across reboots, until you stop it.

Setting DNS Agent to work with a DNS Enabler Snow DNS Server is just as easy. I'll come to it next when I've finished updating DNS Enabler Snow's web page.

But DNS Agent is available now. Only for Snow Leopard.
