Problem:

Need to configure VNC based on xinetd with XDMCP for GDM access

Solution:

1)      1) Install the required packages

# yum install vnc-server xinetd

2)      2) Enable the XDMCP by editing the custom.conf file

# vi /etc/gdm/custom.conf

[xdmcp]

Enable=true

MaxSessions=30

[security]

AllowRemoteRoot=true

DisallowTCP=false

Note: Here “AllowRemoteRoot=true” used to allow root access.

3)      3) Create a file with below content, in inside the /etc/xinetd.d directory

# vi /etc/xinetd.d/xvncserver

service vnc

{

disable = no

protocol = tcp

socket_type = stream

wait = no

user = nobody

server = /usr/bin/Xvnc

server_args = -inetd –query localhost –once –geometry 1024x768 –depth 16 securitytypes=none

}

4)      4) Define the vnc01 service by edit the /etc/services file

# vi /etc/services

vnc   5950/tcp

5)      5) Restart the xinetd and gdm services

# service xinetd restart

# gdm-restart

6)      6) Test using the vncviwer command

# vncviewer localhost:5950

7) To connect from the remote system use the below one
