NAME ^

dynsudp - An udp update server for dyns.cx

DESCRIPTION ^

This server accepts UDP messages containing an update information block and rewrites this to a postscript011.php request.

I got this idea from Paul Lamote, he is also experimenting with siteplayer (http://www.siteplayer.com) - an embedded webserver in 1 square inch - and he wanted to be able to update the dynamic forwarder from his SP (siteplayer) device.

The reason why does not want to use a PC as the updater is because he does not want to use his PC for this task; keeping a PC running costs money and not everybody can have a DSL router and a PC running all the time! Also, if you cannot have a PC running and you need to install an updater on the DSL router, then you'll face a problem as not all DSL routers can be expanded with custom software.

To use this, you'll need to run this daemon on a machine that is reachable from your siteplayer device and that can reach the dync.cx website.

We've run this for some time on dyns.cx, but stopped the support because we did not want to stress the server to hard with all those siteplayer devices out there ;-)

INSTALL ^

Extract the archive in a directory, e.g. /usr/local/dynsudp. Edit the config file to fit your needs. You'll probably need to set the paths. Edit the startup script to reflect your paths.

If you have a proxy to access the internet, then set the ENV variable http_proxy to reflect this.

Use the startup script to start, stop, restart the server and check the status.

PREREQUISITES ^

We need the following modules:

        Net::Server
        Dyns::Client

USAGE SHORT ^

Send the following string to IP address 'ip' and port 20205:

        username|password|hostname|domain|ip

        e.g.

        john|doe|johndoessite|dyns.cx|ip

Port 20205 is default in the dynsudp configuration.

USAGE ^

Basically you'll need to send the following information to the dyns udp service:

  username|password|hostname|domain|ip

Imagine you're user 'username' on dyns.cx and you've the password 'password'. If you have reserved the domain name 'hostname' on dyns.cx, you can update your dynamic dns entry as follow:

  username|password|hostname|dyns.cx|

We've omitted the IP number, this way we take the IP number of the gateway.

You direct a microcontroller to send this string via UDP to the dynsudp service running on IP address 'ip' and port 20205. Or you can test this via a HTML page with a form. look in the SP examples, comes with the SP SDK, on how to do a UDP send.
