if you have ssh setup and running… (you might need to configure your router to let ssh through) you can neatly do filestransfer (SFTP) or even remote desktop interaction with your server.

forwarding grafical output of a single program

while MobaXterm might allow such functionality for windows – this is a uniquely UNIX/LINUX feature 😀

Not to forward the whole desktop – but just the window of one program, even better: even if you do not have any GUI (Gnome) installed and running on your server… you can forward the grafical output to your client.

okay probably not intended for gaming 😀

while xclock (vector grafics) runs smooth

# this is the ssh-server
user@debian:~$ ps uax|grep clock
user      3358  0.3  0.6   9984  6476 pts/1    S+   14:21   0:00 xclock -update -1
user      3360  0.0  0.2   4556  2296 pts/2    S+   14:21   0:00 grep clock

blobby not so smooth (not vector grafics?) – but you can run the game on the server – and the grafical output goes to the client. Maybe this is interesting for thin-client-fat-server kind of infrastructure. But i have to say – it works – but the grafical output is rather slow – (all Hyper-V VMs) despite the fact that it is a LAN session… not sure what is to blame. (I guess for such purpses VNC is better :-D)

Also the Audio-Device Forwarding does NOT work 😀

now: 100% remote desktop

there seem to be problems forwarding a whole session, when different display-managers (gdm3, lightdm etc. pp.) are used – so it is probably better

1. to use a VNC server-client architecture

2. allow on server only VNC connections from localhost

3. tunnel all VNC traffic over ssh

…so weak VNC passwords „do not matter“ so much.

still have to find out what vnc-server-client combination works best across distributions and operating systems. (also windows<->linux, osx<->linux, linux<->windows)

# i tried "gnome-session", suse12(gdm)->debian8.7(lightdm+gnome2)

apt-cache search gnome-session; # search for gnome-session package

therefore it would be vice to tunnel VNC
