[KLUG Members] pppd & dyndns

[Nikolas Reist]

If you have ddclient, then the host will resolve depending on how you
edit the ddclient.conf file.  The ddclient site should tell you how to
do that in detail.  If you have an external router (hopefully) you can
port forward to a statically assigned machine on the internet for vnc
and ssh ports.  You will need to have a vnc application running to get
remote desktop to work.  If you are comfortable with the terminal, then
all you need is ssh.  No matter whether you use a physical router
appliance or a machine sitting on a modem, you need to open the port on
the linux box to accept incoming packets on their respective ports.
Depending on the distro you are using, there may be a graphical method
to configure port traffic in your firewall.  Here is a list of the ports
you need to open.

ssh 22
vnc 5900+n (where n= the number of VT or displays you wish to connect)
vnc-web 5800+n
vnc-java 5900+n

If you use Ubuntu, then you can:

sudo apt-get install firestarter

to get a graphical tool for configuring your firewall (kmyfirewall if
you are running Kubuntu).  Make sure you add these also to your router
config as a port forward if you have a separate appliance.
