Topic: How to use dynamic IP with OpenDNS and Kamikaze?

Hello,

I want to use OpenDNS, but that search page is driving me nuts every time some site doesn’t exists. But they have the ability to disable that and behave normally if you have an account. But my IP is dynamically changing. They support that too, but I just don’t know what and how to take the advantage of it with Kamikaze. I think there is a perl script that do this with OpenDNS but isn’t Perl too heavy for WRT54GL? Tomato firmware has this capability to dynamically update your IP to OpenDNS built in…

Is anybody over here done this with Kamikaze? If so, could you please share? Thanks

x-wrt has a buildin ddns support in its web interface, you need to install ddns package and a package for your ddns provider(saying opendns), I am not sure if opendns is in the supported list, mine doesn't, so I have to write a script and put it to crond to do it.

With crond OpenDNS would be updated only by time interval right? How about adding a cache file like ez-ipupdate uses to keep from abusing your dyndns provider. Or is there any way to use ez-ipupdate to send the update to OpenDNS along with dyndns.com? I would like to only send an update to OpenDNS when my dynamic ip address actually changes.

The discussion might have continued from here.
