# The VNCSERVERS variable is a list of display:user pairs.

#

# Uncomment the lines below to start a VNC server on display :2

# as my 'myusername' (adjust this to your own).  You will also

# need to set a VNC password; run 'man vncpasswd' to see how

# to do that.

#

# DO NOT RUN THIS SERVICE if your local area network is

# untrusted!  For a secure way of using VNC, see this URL:

# http://kbase.redhat.com/faq/docs/DOC-7028

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

# Use "-localhost" to prevent remote VNC clients connecting except when

# doing so through a secure tunnel.  See the "-via" option in the

# `man vncviewer' manual page.

# VNCSERVERS="2:myusername"

# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
