====== Howtos and Tips ======

===== DynDNS =====

DynDNS is a service that allows you to have a static domain name even if you don't have a static IP. You have to :
  - create a free account at [[http://www.dyndns.com/]] or another provider. Usually you can also configure a real domain name as a dynamic host (eg OVH).
  - configure a //Dynamic DNS// in this account
  - install a software client on your computer that will automatically update the hostname ([[http://www.dyndns.com/support/clients/|DynDNS Updater]] for Windows or [[http://www.dyndns.com/support/clients/mac.html|Mac]], [[http://www.dyndns.com/support/clients/unix.html|ddclient or inadyn]] for Linux)
  - or you can also configure your modem if it supports DynDNS (//NeufBox//, ...), then you don't need to install a client.

==== Trick to use providers unsupported by your modem  ====

Several modems (//NeufBox//, ...) only support dyndns.org, which makes it impossible to use a real domain name bought to a real registrar.

Fortunately there is a trick : you have to add a DNS entry in your modem for making "dyndns.org" point to the IP address of your real provider.

Needs testing with OVH.

Problem: Neufbox 4 limits the user name at 15 characters, and the domain name at 20 characters...
