you are missing "tigervnc-server-module"!

no idea what "x11vnc" is but this are my
vnc-related packages while "tigervnc" is
the client to connect to remote-machines

[root@srv-rhsoft:~]$ rpm -qa | grep vnc
tigervnc-license-1.1.0-3.fc16.noarch
tigervnc-server-module-1.1.0-3.fc16.x86_64
tigervnc-1.1.0-3.fc16.x86_64

"/usr/bin/vncpasswd" for create "/root/.vnc/passwd"
is contained in "tigervnc-server-minimal" which can
even be uninstalled after all works!

http://rpm.pbone.net/index.php3/stat/4/idpl/17378318/dir/fedora_16/com/tigervnc-server-minimal-1.1.0-3.fc16.x86_64.rpm.html

well, this is a F16 link / system, but i am using this config
since years on several machines while iptables is blocking the
vnc-port and connect is done with a shell-script creating a
ssh-tunnel and fire up "vncviewer" with the needed params

where did you?

i see no "tigervnc-server-module" in your list
tigervnc-server-module != tigervnc-server-minimal

the "vncserver"-stuff i stripped of your reply has nothing
to do with vnc-access to display 0, this is a totally different
topic because it starts a whole session and give you no access
to the same screen as on the local machine like xvnc does

there is no need to reboot, this is no kernel-update :-)
"killall X" will restart X11

Don't know how I missed the module when I did "yum search vnc".
Adding that package fixed it for me. Thank your for time.

the main question is where you missed my post about the package
replying "I just installed that package prior to your response"
but who cares, now it works :-)

But I can do it already.

I log in to the system via ssh and start the vnc server.

Then I create an ssh tunnel, and connect to the VNC server I just
started. VNC goes through SSH.

What's the problem with what I just described?

Hello,

Have you tried with "vino"? I prefer it than a separate VNC server with
a separate display.


With Vino, I can log in locally to my desktop at office; i would lock
the screen when i leave my office and when i arrive home i would connect
to the same desktop/display i left off at office with a normal VNC
client (RealVNC for windows).


Just do:

yum install vino
vino-passwd
vino-preferences


HTH
Regards,
Khem

I don't get the problem. You don't have to be logged in on
the console, or anything like that. You just have to be able
to start a vnc server, and you can do that via ssh. What else
do you want to do?

I have no problems doing the major of the work needed via ssh and
command line. However, there are a few things that requires the GUI,
specifically Oracle, for me to do a few things. Setting the autologin
would allow me to VNC into the system, especially when the system is
rebooted.

But I can do it already.

I log in to the system via ssh and start the vnc server.

Then I create an ssh tunnel, and connect to the VNC server I just
started. VNC goes through SSH.


However, that poses a security risk for me. Basically, I'm
looking for something similar to MS Windows' RDP. Whether the user is
logged or not, anyone with the right access can RDP in. IIRC, the old
original VNC server used to do that on Windows. I haven't used VNC
server in about 10~ years.

What's the problem with what I just described?

Andrew.

you recognized that it was solved yesterday? :-)

"vino", "vncserver" and others can not provide "Whether the user is
logged or not, anyone with the right access can RDP in. IIRC, the old
original VNC server used to do that on Windows."

this can only be done with xvnc sahring display 0
_____________

example to show the big difference

* i connect via ssh to our admin-server in the LAN
* type "wol workstation (/etc/ethers is your friend)
* my workstation is powered on and boots to kdm login
* "vnc.sh workstation" creates a ssh-tunnel and connects to display 0

this way i can power off my machine completly and control it
from remote like with physical access
