The following is an extension to https://www.dyndns.com/services/dns/dyndns/howto.html

In order to have a dynamic dns address, do the following:

- Open an account at http://www.dyndns.com/

- Now we have to install a client to update the ip address everytime we have a new IP address: in this case from synaptic I chose ddclient (see also http://www.dyndns.com/support/clients/ )
# sudo apt-get install ddclient

To configure ddclient, edit the file /etc/ddclient.conf and run
the tool in https://www.dyndns.com/support/tools/clientconfig.html
In the webpage of ddclient: http://ddclient.wiki.sourceforge.net/ you can learn how to configure it.
A tutorial for configuring ddclient in dyndns.org is https://www.dyndns.com/support/kb/using_ddclient_with_dyndns_services.html


Another tools for linux are
- ndyndns >> http://code.google.com/p/ndyndns/
- and the ones in https://www.dyndns.com/support/clients/unix.html


In order to check if ddclient is working...
$ nslookup earendil.dyndns.org
You can also try to go to
https://www.dyndns.com/support/tools/dnsquery.html
and in the field Query and Record Type: write down earendil.dyndns.org


OPEN THE PORTS IN THE ROUTER... PORT FORWARDING
http://portforward.com/
https://www.dyndns.com/support/kb/routers_and_port_forwarding.html

To see if you can access the computer from outside, check that the ports are open with https://www.dyndns.com/support/tools/openport.html


Finally, install OPENVPN ( https://www.dyndns.com/support/kb/using_openvpn_with_dyndns.html )
