Password:
Verify:
[kevin.ngo@localhost .vnc]$
4. Configure VNC configuration for new user
[root@localhost ~]# cat /etc/sysconfig/vncservers
# 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 800×600 -nolisten tcp -localhost”
VNCSERVERS=”2:kevin.ngo”
