I have Fedora version 5 installed in one machine, in that machine I have a software that need settings, and in that settings I set host=xyz.dyndns.org (actually that host is a remote router existed in other area), when I restart the router so it takes new IP address and it updates that new IP address at dyndns.org and I see this. The problem that still at my fedora machine, I have to restart the machine so host=xyz.dyndns.org will be refreshed and updated and directs to the new IP address, so traffic will be send successfully.
How can i resolve this problem and have a refresh automatically (periodically) so when I need to sent for the host=xy.dyndns.org, then I will send to the right IP address instead of the old IP address? Even if update was possible to be every 1 minute or 5 minute it is accepted. How? Or at least to have update when my fedroa machine is going to send traffic for host=xyz.dyndns.org, so it should refresh and get the new IP address for that domain, How?
I think it something related to refresh cash and so on, but I do not know any thing about that, any one can help?
