Does anyone know if there exist an application which allows admin run other apps in kind of desktop environment. What i mean is a kind of VNC application which only gives user the terminal console, but when user disconnects, the daemon will be still running, so for example:

  • User connects to server and to the daemon.
  • In this daemon console user runs mc starts copying a big file
  • User disconects and connects again.
  • The mc is still performing the copy of some big file etc.

I know that nohup allows to run app without in/out stream but one cannot "reconnect" to working process.

    Perhaps screen or tmux... – jimmij Jan 30 '15 at 16:52

    When using nohup, the process keeps running in the background... you can still query for it if you took note of the PID and then use ps. Logging out and in again will not interrupt that process in any way. For what you describe, then screen could be the program you are looking for. – jimm-cl Jan 30 '15 at 16:55

    screen and tmux will do this for applications that run in a terminal window. I don't know if there's a VNC-like solution for a GUI. – Barmar Jan 30 '15 at 17:05

Option 1: ssh to the remote server, then run screen or tmux (I prefer tmux). Exit by 'Ctrl-a d' or 'Ctrl-b d' respectively. When you ssh again there and run tmux attach or screen -r you will resume your session

Option 2: To have graphical software resumed the same way, install xrdp on the remote server. This will start an X server on the remote host to which you can connect with e.g. an RDP client (rdesktop). The X session on the remote server will stay alive when you disconnect.
