TigerVNC server on Linux (Ubuntu or Alt Linux) for simultaneous operation of more than ten users in X

[Stanislav Matsak]

I was unable to launch more than 9 connections for users to work on Linux from standard TigerVNC distributions.

That's why I came to you, downloaded deb for Ubuntu, installed it.

The startup parameters are very different from those that were before, so I ask you to give some examples of how to start the server.

I have a console server with xinit and fluxbox as a window manager.

I'm trying to run server like this

Xvnc :1 -rfbauth /home/user/.vnc/passwd

session configuration:

cat /home/user/.vnc/Xstartup 

#!/bin/sh

unset SESSION_MANAGER

  unset DBUS_SESSION_BUS_ADDRESS

    vnconfig -nowin &

  exec dbus-launch fluxbox

I would be grateful for any help on this issue.

when connected, I see a black screen, no fluxbox

If you can connect then that means that TigerVNC is up and running, so
I'm afraid the issue must be in fluxbox somewhere.

Have you checked if it is the fact that you have 10 sessions that is the
problem, or if it just that display :10 that's broken? :10 is commonly
used for SSH forwarding so it has happened that some programs have
special hacks for that.

Hello.

Thanks for the quick response.

The problem with :10 screen, I can't jump it in any way in the standard tigervnc from the distribution.

vncserver -rawkeyboard :9 opens normally, like all the previous ones.

vncserver -rawkeyboard :10 - does not open and you said why.

vncserver -rawkeyboard :11 - does not open because :10 is not open.

I came to you hoping to can register a specific user in a specific tcp socket, with a unique password for each user to avoid confusion when connecting users.

Judging by the incomplete picture of your the solution  in my understanding, it's knows how to do it.

I ask you to recommend me how to do it better, preferably with an example.

Thank you in advance.

an easy way, :)

I just need to not try to run :10 screen, after :9 run immediately :11.

I tried, and I succeeded.

This means that I can get by with the standard tigervnc from the distribution.

Thank you very much, you helped me a lot.

Your solution can bigger, but it is more complicated in the settings, if not problem - provide some examples. so that I understand how to use it.

I am very glad that I came to you.

netstat -ntpa | grep vnc
