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

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 )

Iceweasel as Firefox

Everybody knows Iceweasel is actually Firefox 3, everyboby except Google. When you visit http://gears.google.com, an ugly message says “your browser is not supported”.

The solution is easy: trivial user agent cheating

1. Point your iceweasel to “about:config”.
2. Find a key called “general.useragent.extra.firefox” and edit to “Firefox/3.0.5”

Red prompt when ROOT

edit /root/.bashrc and add

if [ `id -u` = 0 ] # check if user is root
then
PS1="$RED[\u@\h:\W]$RESET "
else
PS1="[\u@\h:\W]$RESET "
fi
}
setprompt
