Anyway, it is not symmetric bandwidth. It is 300 Mbit download, and I don't remember what upload, but much less, perhaps 30. Another competitor offers 300 symmetric. I'll have to check again what I really have now, then get dyndns or something (whatever my router supports directly, I guess).
You can always run a dyndns update from a cronjob.
Yes, I know. But there will be an interval, after my ISP changes my IP till the script runs, that they will not match.
Doesn't really matter much, but those are the terms when you don't have a fixed IP.
Years ago, I managed to write a script that logged into my router and interrogated it for the external IP. In my current router I don't see I can do this.
You don't need to - the dyndns provider will always know where the request is coming from.
The advantage is that it is fast, not requiring to query an external web page.
Hmm, every dyndns provider I am aware of uses http(s) as the interface protocol. You can't avoid the external query. The advantage of having built-in router support is in the reduced latency, i.e. how much of a pause between the IP change and the DNS change. (ignoring the DNS TTL). Many routers allow you to specify arbitrary request strings, so you can work with non-hardcoded dyndns providers. -- Per Jessen, Zürich (13.1°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
