3.1 Remote Desktop

XRDP

sudo apt-get install xrdp

It will start automatically and listen on port 3389. Make sure to open the port on your router if needed, and add the following rule to iptables (see the section on firewalls on how to do this):

-A INPUT -p tcp --dport zzzz -m state --state NEW -j ACCEPT

Now you can login with using any remote desktop client.
