KRFB Remote desktop as daemon

Tue Apr 16, 2013 6:57 am
I'm using KRFB as remote desktop server in my Linux Mint KDE.
It works fine as usual remote desktop server but I've to log-in then run it manually (or at start up)

How can I run KRFB as daemon without need to log-in at first?

PS
As I know "upstart" for CLI not for GUI applications.

Google'ing returns:

http://linux.die.net/man/1/daemonize
http://software.clapper.org/daemonize/

no experience with this but sounds appropriate

I open my post after gave up from google :( "daemonize" just like "upstart" both of them run the applications as daemon but those applications have to be CLI not GUI. KRFB is GUI based so upstart can't run it as daemon.

maybe you can't, maybe you need to setup a vnc or nx server to run as a daemon

seems like to use krfb you'd need to autologin when the server was booted then autostart the app

might be better to start a thread with something like "graphically accessing a remote machine at boot"

The problem with auto-login is the security, because it needs some minutes until activating system locking.

If any one guide me to a way for locking the system in duration less than 1min this will fix the whole issue.

If you are looking to be able to login as different users on the system then you need to setup VNC / NX as mentioned previously to achieve the desired goal.

If however, you are just looking to work as a single user on the system, then KRFB should work for your purposes.
To enable automatic lock on login, set "DESKTOP_LOCKED=1" as part of the environment when the user logs in.

The easiest way to do this is by creating a executable script file in "~/.kde4/env/". If you do not have a ~/.kde4/ directory but do have ~/.kde/ then it belongs in ~/.kde/env/ instead. This file must have a .sh extension, and the environment variable in question should be exported.

I create executable locking.sh file in "~/.kde/env/" and I noticed that this file is added to KDE's Autostart

The content of locking.sh:
Code: Select all
#!/bin/bash

export DESKTOP_LOCKED=1

Yes, that is to be expected, as the script file you added (assuming it is executable) is invoked as part of the KDE startup process - which is how it works. Did adding that have the desired affect of locking the desktop on login?

Actually it didn't affect at all although I set it as executable.

Ah, i've just checked the code. It turns out the variable is only "DESKTOP_LOCKED" to a point before where those environment variable scripts are sourced - it changes to "dl", and then sources those scripts.

Please adapt your script to set "dl" instead of "DESKTOP_LOCKED" - hopefully this will fix it.

Thanks a lot for your suggestion but I discovered that GUI system settings offers that option without creating any .sh files manually (Lock Session).... Voila ;D
