I will be giving my Dad a computer within the next couple of days, and I will need to set it up so that I am able to remotely administer it while he is at home 3,000km away.

I haven't used RDP etc before.

I discovered today that my computer already has Remmina installed, and I have a spare computer to test it all with before my Dad's new computer arrives.

I installed Remmina on the spare computer this morning.

I am able to start Remmina on either of these two computers.

I want to use the spare computer to control my main computer. On my main computer, I 'ifconfig' in a terminal and get the IP address 192.168.178.35.

  • I start Remmina on the spare computer
  • create a new connection
  • leave the default connection name
  • Protocol>RDP
  • Server 192.168.178.35
  • User el_gallo_azul (my account user name on the main computer)
  • Password (I enter the password of my account on the main computer)
  • Domain - leave blank because I don't know what's supposed to go here
  • Click 'Connect'

This gives the error "Unable to connect to RDP server 192.168.178.35"

I have set my Desktop Sharing Preferences on my main computer to 'Allow to view' and 'Allow to control'.

I can't find any instructions on the internet.

This doesn't bode well for when I am trying to access a computer that isn't even on my home network.

  • The 'Desktop Sharing' in Ubuntu desktop is provided by a VNC server (vino-server) rather than an RDP server - try connecting your Remmina client using VNC protocol instead. Dec 22, 2014 at 1:37
  • Thanks @steeldriver. It was actually your comment on ubuntuforums.org/showthread.php?t=2177810 that got me a little bit further. Dec 22, 2014 at 1:51

On ubuntuforums.org/showthread.php?t=2177810, I discovered that I should use a different protocol. I'm now using VNC, and once I discovered that I should accept the connection on my main computer, I got it to work. Now to figure out how do it over the internet... I would appreciate any hints.

  • I've had a look for methods to remotely connect over the internet without static IP address, dynamic dns or any installation on the client side, and the closest that I've found is TeamViewer, but I don't think that is going to work because of the client download (for an instance of support) being a .tar.gz file ([link]download.teamviewer.com/download/teamviewer_qs.tar.gz)).
