Using VNC to use a remote desktop in the HDA (Fedora 12)

Using VNC is useful if:

  • You would like a Linux desktop to the HDA remotely
  • You run your HDA headless (no monitor) and like to still use a desktop in it
  • You would like to use a GUI to configure printer(s) or have a scanner or other device that requires a desktop program to configure and the machine is headless

What you need

  • A server
  • A client

Client: Installation

Download the client software and install:

yum -y install tigervnc

Server: Installation - Method 1

  • To start the server in your HDA, you need install tigervnc-server rpm package:
  • From the root user:
yum -y install tigervnc-server
chkconfig vncserver on
service vncserver start
  • Edit /etc/sysconfig/vncservers and change lines as follows (username is your linux user for the VNC session):
VNCSERVERS="2:username"
VNCSERVERARGS[2]="-geometry 1024x768 -nolisten tcp -localhost"
  • Edit /home/username/.vnc/xstartup and make the end of the file look as follows:
# twm &
startx &
  • Stop and start vncserver:
service vncserver stop
service vncserver start
  • Start VNC on reboot (do this as your linux user for the VNC session):
crontab -e
@reboot vncserver
  • Run your VNC Client and enter hda:1 as the host/IP address. You should now see your HDA Desktop screen.

Server: Installation - Method 2

  • To start the server in your HDA, you need install tigervnc-server rpm package:
  • From the root user:
yum -y install tigervnc-server xinetd
chkconfig vncserver off
service vncserver stop
  • Create /etc/gdm/custom.conf file and add the following:
#GDM configuration storage
[xdmcp]
Enable=true
[chooser]
[security]
DisallowTCP=false
[debug]
  • Create /etc/xinetd.d/vnc1024 file and add the following (you can change the screen resolution by changing the geometry setting):
service vnc1024
{
disable = no
socket_type = stream
protocol = tcp
group = tty
wait = no
user = nobody
server = /usr/bin/Xvnc
server_args = -inetd -query localhost -geometry 1024×768 -depth 16 -once -fp /usr/share/X11/fonts/misc -securitytypes=none
}
  • Edit /etc/services and comment out the two lines as listed below:
#vnc-server      5900/tcp                # VNC Server
#vnc-server      5900/udp                # VNC Server
  • Add this line below the two lines you commented out and save the changes:
vnc1024         5900/tcp                # VNC and GDM
  • Now restart the xinetd service
service xinetd restart
  • Run your VNC Client and enter your HDA IP address for host/IP address. You should now see your HDA Desktop login screen. If you don't see the login screen, a reboot of the HDA may be required. This can be done via the dashboard or by executing the following as root user:
reboot now
