what have i done:

sudo pkg install x11vnc
sudo x11vnc -storepasswd /etc/x11vnc.pass
sudo x11vnc -display :0 -rfbauth /etc/x11vnc.pass

and it works fine.

But i can't find a working solution for a startup script for FreeBSD or GhostBSD.
All other Linux scripts are not working here.

Example: sudo systemctl enable x11vnc.service

how can i enable that in GhostBSD?

I hop that the man pages will bring you a step further:
https://www.freebsd.org/cgi/man.cgi?que ... ormat=html

There is no service for x11vnc in FreeBSD and GhostBSD also systemctl command will not be find on FreeBSD systems.

Hi ericbsd,
did You mean, there is no way to start x11vnc on boot?
And it is waisting time to follow slughorn?

Hi slughorn,
thanks for the link. I know about this and similar pages. I use those pages when i want to optimise some exsisting routines.
But in this case i am just a primary schoolboy. I don't know, how to start with building a startup routines for BSD.
I can read text, i can write it to a terminal and then i cont on it to work.
I found a lot of posts with some rc.d-scripting and i think that is the way i have to go.
I found this: https://www.freebsd.org/doc/en_US.ISO88 ... index.html
and i tried point 3, the dummy script, and it worked (after a reboot).
But i have no idea how i get this: "x11vnc -display :0 -rfbauth /etc/x11vnc.pass" to work with a rc.d-script.
I tried this:

#!/bin/sh

. /etc/rc.subr

name="runx11"
start_cmd="${name}_start"
stop_cmd=":"

runx11_start()
{
x11vnc -display :0 -rfbauth /etc/x11vnc.pass
}

load_rc_config $name
run_rc_command "$1"

but that doesn't work.

In this case i need some help.

There are some rules. Please read here https://wiki.ghostbsd.org/index.php/OpenRC

Hi slughorn,
thanks for the additional informations, but it is really too much for me.
There is only one command line (it works perfect when i type it manually):
"x11vnc -display :0 -rfbport 5900 -localhost -bg -rfbauth /etc/x11vnc.pass"
I found some examples and i edited them, but i had no success.
Is this so ununsual what i'm trying? Or is there a better way to connect to the desktop with a VNC-Viewer?

I'm not a developer yet. But if your command works on the cli, I would try the following steps:
1. Make a shell script "foo" (foo ist a replacement for your script name] and test it
2. Save this skript in the dirctory (There are some examples too, take as an example cupsd in this directory)
3. Make 4. Take [https://wiki.ghostbsd.org/index.php/Rc-update rc-update] and make With rc-update you can safely add the new service
5. Report me please, if it works
