Post subject:  R6: VNC remote Acess
Hi People,

I almost have VNC (x11vnc) working with a password in R6. But I can not figure out how to make it run on startup. Here is what I did.

R6: VNC remote Access

Please note the defaut is with NO password.
WARNING: This will set up VNC with NO PASSWORD. This means that ANYBODY who has access to the network the computer is on CAN SEE YOUR XSERVER.

To install x11vnc

pacman -Sy x11vnc


To configure it for no password use
x11vnc -display :0 -auth ~/.Xauthority

Tto configure it with a password use the line below, you will be prompted for a password and then to save it.
x11vnc -storepasswd

To run it use the line below
x11vnc -usepw -display :0


Here is my sticking point, making it start by default. I have tried the line below. But my brain is a pile of mush from work this week (and my kids have not been sleeping). So any pointers in the right direction would be great.
sudo sv start x11vnc -usepw -display :0

Thanks,

Paul

Same config as 5.5 add the following line to /home/mythtv/.fluxbox/apps. Its all on one line and this is for an NVIDIA card.

[startup] {/usr/bin/x11vnc -nap -wait 50 -noxdamage -passwd XXXXX -display :0 -forever -o /var/log/x11vnc.log -bg}

This did not work for me on my R6.

I can run the command from the command line and VNC works so I know VNC is installed and working correctly.

I doesn't survive a reboot with the line added as described.

I'm not sure what I am doing wrong?

Thanks for the help.

II figured it out. Permission problems:

If I make a .vnc in ~ and point it there, all is well:

Code:
$ x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o ~/.vnc/x11vnc.log -bg
PORT=5900

Looks familiar :)

I just installed it from CD on my spare Athlon X3200+ system. Initial impression is OMG. You guys did a a TERRIFIC job with the installer. I was blown away. R6 is very slick.

Entire install and reboot in under 10 min. First thing I noticed is that x11vnc isn't included. First thing I did was added the official Arch repos to /etc/pacman.conf (core, extra, community) and updated pacman via # pacman -Sy. I went on to install x11vnc and added the following to mythtv's .fluxbox/apps

Code:
[startup] {/usr/bin/x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o /var/log/x11vnc.log -bg}


When I did the usual $ pkill xinit, x11vnc didn't startup at all. I checked and indeed no /var/log/x11vnc.log

What am I missing?

EDIT: I figured it out. Permission problems:

Code:
$ x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o /var/log/x11vnc.log -bg
error opening logfile: /var/log/x11vnc.log

Code:
$ x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o ~/.vnc/x11vnc.log -bg
PORT=5900


Is x11vnc something you're planning to have in place when R6 officially launches?


To anyone using X11vnc on R6, PLEASE beat up on it. I found that mine isn't very robust, freezes on the client end requiring a pkill xinit. I haven't been able to track it down, and was going to wait for cesman/others to 'officially' put X11vnc into the distro to repeat and then file a bug report if needed.

It has to write to the log file as well. Should have mentioned this earlier sorry.

create the logfile:
Code:
touch /var/log/x11vnc.log


then make it writable for all:
Code:
chmod 766 /var/log/x11vnc.log

@weblst - I think as long as your specify a location on the file system owned by the user who started it (mythtv in this case), you shouldn't have to pre-make the file.

Code:
$ mkdir ~/.vnc


That should be sufficient. You don't have to make a hidden directory... it can even be your home directory. Anyway, test it like this:

Code:
$ $ x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o ~/.vnc/x11vnc.log -bg


That should say something like "PORT=5900" or else it will give some errors relating to the log file.
