Jabber based DynDNS

How do I use Jabber-based DynDNS?

  1. Look for the resource name in your client's configuration dialogue/file. In most cases this contains the client's name. This will be modified.
  2. Enter your computer's hostname (excluding the domain name) ending with a sharp ("#"), i.e. "pc05#". Instead of the hostname you can also use i.e. some name describing your computer's location or usage (for example "home#", "at-work#" or "notebook#"). As this will be used as a hostname element, only a-z, 0-9 and a dash ("-") are allowed. Its length needs to be 3-20 characters.
  3. Log out from Jabber server and log in again.
  4. Assuming your JabberID is poweruser@legalized.de, your system will now be accessible via poweruser.dyn.legalized.de.
  5. If you are using a single Jabber account from multiple computers (simultaneously), be aware that "poweruser.dyn.legalized.de" always refers to the IP address of the system that most recently logged in. In this case you can access every single system via the resource address you just entered: Assuming your systems use the resources "home#" and "work#", one system will be known as home.poweruser.dyn.legalized.de and the other as work.poweruser.dyn.legalized.de.
  6. Hostnames are being updated with an average delay of 2.5 seconds after logging in.
  7. The TTL (time to live: delay until a remote system will request a new IP address for the hostname) of the records is 60 seconds.
  8. Hostnames will be flushed if the user does not lo log in for 7 days.
