Setup VNC server.

# yum install tigervnc-server

Make new configuretion for display N.

For display :2
# cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:2.service

Replace parametr “”:

#ExecStart=/sbin/runuser -l -c “/usr/bin/vncserver %i”
ExecStart=/sbin/runuser -l myuser -c “/usr/bin/vncserver %i -geometry 1366×768″
#ExecStop=/sbin/runuser -l -c “/usr/bin/vncserver -kill %i”
ExecStop=/sbin/runuser -l myuser -c “/usr/bin/vncserver -kill %i-geometry 1366×768″

Restart.

# systemctl daemon-reload

Set password VNC for user myuser

# su – myuser
$ vncpasswd
Password:
Verify:
$ exit
logout
#

Enable & run vnc service.

# systemctl enable vncserver@:2.service
# systemctl start vncserver@:2.service

Set firewall
-A INPUT -m state –state NEW -m tcp -p tcp –dport 590 -j ACCEPT

Thiis is a very detailed article. After reading several others and failing, I felt like this gave the best explanation. However I am still having issues. Here is what happens:

[root@fel1 ~]# service vncserver restart
Redirecting to /bin/systemctl restart vncserver.service
Failed to issue method call: Unit vncserver.service failed to load: No such file or directory. See system logs and ‘systemctl status vncserver.service’ for details.

2. So I say, let’s continue to try if service does not work. So as root I simply isssue command:
[root@fel1 ~]# vncserver

New ‘fel1:1 (root)’ desktop is fel1:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/fel1:1.log

3. Then I go to my windows machine and start the vcn viewer and in the ip address field I put it
192.168.1.78:5901:1

But I get the message:

unable to connect to host: A socket operation was attempted to an unreachable host (10065)

I have setup my windows firewall to open port 5901 and set up my router to forward port 5901.

What is the meaning of the message from service command and then from the viewer?

@BKing1138: Thanks for your feedback. Right, I didn't notice that mistake... In that case the vnc instance most probably does not start correctly. The logfile inside the ~/.vnc/ directory should be checked and of course the "geometry" statement should be written properly.

P.K.,

Was the “-geomatry 800×600″ a typo? If not, then should that not be “-geometry 800×600″?

If your /etc/sysconfig/vncservers files is actually correct, then I would agree it is likely that your firewall is not allowing the connection.

Smells like a network misconfiguration or a firewall that prohibits connection to the vnc service.

I can configure my server (on FC-5 Linux) and it starts fine but when I attempt to connect to it
from a client on windows machine, I get this error:
{ when I debug it using TCPDUMP }

server-name > client-name unreachable – admin prohibited, length 56

On the server I have:

VNCSERVERARGS=”2:username” (actual user name here)
VNCSERVERARGS[2]=”-geomatry 800×600″

Can someone tell what is going on my server which is maing it refuse connection?
I can start local VNC viewer on the sever machine, but remote connection is prohibited.

Thanks in advance.

Answers: 1. I am sure I had seen such information at the Fedora Forums. You can securely connect to the VNC server (either remote desktop or graphical greeter) through an SSH tunnel, as described in this article. 2. You can use the gdmsetup utility to configure these setting from a graphical interface.

Two questions:

1. Can you point me to or provide some good information on securely connecting to the vnc-server at the “graphical greeter” login screen. (I’m using Fedora)

2. Can you disable others from viewing the remote screen while you are connected to it from a remote location. I mean people that would actually be in front of the server while you are connected to it.
