Fedora - VNC through systemd/xinetd

Configuring Fedora 17 for Xvnc through systemd/xinetd

I found a number of links around but nothing exactly covered my setup.  I wanted to be able to run an X11 session from home as securely and efficiently as possible.  After configuring my home server like this:

1. sudo yum install xinetd tigervnc-server-minimal
2. sudoedit /etc/gdm/custom.conf

[security]
RelaxPermissions=0

[xdmcp]
Enable=1
HonorIndirect=1

[greeter]
Quiver=1

3. sudo useradd -d /var/empty/vncuser -m -s /bin/false vncuser
4. sudoedit /etc/services

vnc-1280 5910/tcp # VNC Listener

5. sudoedit /etc/xinetd.d/vnc

# BEGIN
service vnc-1280
{
socket_type = stream
protocol = tcp
wait = no
user = vncuser
server = /usr/bin/Xvnc
server_args = -inetd -query localhost -desktop 1024x768x24 -once -geometry 1024x768 -NeverShared securitytypes=none
}
# END

6. sudo systemctl start xinetd.service

And you will need to restart GDM.  I couldn't get the systemctl restart prefdm stuff quite right, so I rebooted.  (Yeah, I know lose massive points for that shortcut)

I then can ssh from a remote box and bring up a GDM login:

1. ssh -4 -a -L 5900:localhost:5910 user@6.6.7.8
2. vncviewer -PreferredEncoding "Tight" localhost:5900
