Install and configure VNC Server in Fedora 20
Please follow the below mentioned steps to install VNC server in a Fedora 20 box.
Step 1 :
Install the Tiger VNC server package
Step 2 :
Now we need to copy the VNC server configuration file if you need to setup port-offset for VNC server. By default VNC server uses port 5900, so port-offset means we can run the service on a sub-port of the default port 5900. Say for example port 10, so actually VNC server will accessible on port 5910. When using the port-offset we can connect to the VNC server by just specifying the IP address:sub-port format. Eg:- 10.30.0.78:10
Now edit the copied file and make changes as mentioned below.
The copied file will look the following.
I have used a user named “qatest”, so in my example this user is running the VNC server. So my file will look the below one. Please choose your user and change accordingly.
Now add exclusion in the firewall for the VNC connections to your server.
Step 5:
Now setup a password for the VNC user.
So login as the particular user and do as below.
Now reload the systemctl daemon and start the VNC service.
IF you need to set the resolution for the VNC desktop, please edit “/etc/sysconfig/vncservers”
Step 8:
Now connect from a Windows machine using the VNC client, say for example I have used TightVNC.
If everything goes right, you will get a password prompt as below.
That’s all, Done!!!…
Step 1 :
Install the Tiger VNC server package
[root@fedora20test ~]# yum -y install tigervnc-serverThis will install the VNC server. Now we need to configure this.
Step 2 :
Now we need to copy the VNC server configuration file if you need to setup port-offset for VNC server. By default VNC server uses port 5900, so port-offset means we can run the service on a sub-port of the default port 5900. Say for example port 10, so actually VNC server will accessible on port 5910. When using the port-offset we can connect to the VNC server by just specifying the IP address:sub-port format. Eg:- 10.30.0.78:10
[root@fedora20test ~]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:10.serviceStep 3:
Now edit the copied file and make changes as mentioned below.
The copied file will look the following.
[root@fedora20test ~]# vi /etc/systemd/system/vncserver@\:10.service [Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/sbin/runuser -l -c "/usr/bin/vncserver %i" PIDFile=/home//.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.targetReplace all <USER> with the username that should be used in your environment.
I have used a user named “qatest”, so in my example this user is running the VNC server. So my file will look the below one. Please choose your user and change accordingly.
[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/sbin/runuser -l qatest -c "/usr/bin/vncserver %i" PIDFile=/home/qatest/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.targetStep 4:
Now add exclusion in the firewall for the VNC connections to your server.
[root@fedora20test ~]# firewall-cmd --permanent --zone=public --add-service vnc-serverThis will permanently add exclusion in the firewall for the VNC service.
Step 5:
Now setup a password for the VNC user.
So login as the particular user and do as below.
[qatest@fedora20test ~]$ vncpasswd Password : Verify :Now you will be asked to enter the password twice, please do so. After this a new directory (.vnc) will be created under the home directory of the vnc user with a passwd file in it.
[root@fedora20test ~]# ls -l /home/qatest/.vnc/ -rw-------. 1 qatest qatest 8 Feb 20 17:55 passwdStep 6 :
Now reload the systemctl daemon and start the VNC service.
[root@fedora20test ~]# systemctl daemon-reload [root@fedora20test ~]# systemctl enable vncserver@:10.service [root@fedora20test ~]# systemctl start vncserver@:10.serviceThis will create an xstartup under the .vnc directory of the specific user account.
[root@fedora20test ~]# ls -l /home/qatest/.vnc/ -rw-------. 1 qatest qatest 8 Feb 20 17:55 passwd -rwxr-xr-x. 1 qatest qatest 355 Feb 20 17:11 xstartupStep 7 :
IF you need to set the resolution for the VNC desktop, please edit “/etc/sysconfig/vncservers”
[root@fedora20test ~]# vi /etc/sysconfig/vncserversAfter editing please restart the VNC service.
Step 8:
Now connect from a Windows machine using the VNC client, say for example I have used TightVNC.
If everything goes right, you will get a password prompt as below.
That’s all, Done!!!…

The correct command is:
firewall-cmd –permanent –zone=public –add-service vnc-server
——-
[root@localhost ~]# firewall-cmd –permanent –zone=public –add-service vnc-server
success
——-
Otherwise, you will get the following error in Fedora20, quite obviously :-)
——–
[root@localhost ~]# firewall-cmd permanent –zone=public –add-service vnc-server
usage: see firewall-cmd man page
firewall-cmd: error: unrecognized arguments: permanent
[root@localhost ~]# firewall-cmd permanent –zone=public –add-service vnc-server

Rest of the article is OK and really appreciate the clear style of writing the instructions.

Any response with a work around would be greatly appreciated. I don’t think anyone has a solution to it yet.
All I need is to load a Gnome session in the tightvnc viewer on the remote computer. I just get a message from gnome in the vncviewer saying: Oh no! Something has gone wrong. and then a logout button and after clicking it I get a black screen. This message seems to come from gnome itself.
I think the solution is to hack around with these two files but I don’t know how or which one to amend? Maybe the gnome session isn’t loading properly?
file 1: /home/user/.vnc/xstartup
file 2: /etc/systemd/system/vncserver@:10.service
Thank you.
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@\:10.service
To accept connections to your current desktop use:
x0vncserver -rfbport=59** -PasswordFile=/home//.vnc/passwd -display :0
PLEASE HELP ME FIXING THIS

But then just get a blank/black screen when connecting to the server. Thoughts?
