Redhat/CentOS: X11 forwarding request failed on channel 0

Was trying to forward xdisplay back to local computer from the remote a Redhat 6.5 server via SSH,

ssh -X user@remote-redhat-server
xterm

got the following error:

X11 forwarding request failed on channel 0

Solution:

• Login the remote Redhat server via ssh:

  ssh user@remote-redhat-server

• Enable X11 forwarding in /etc/ssh/sshd_config:

  sudo vi /etc/ssh/sshd_config

  X11Forwarding yes
  X11UseLocalhost no

• Install xauthroity:

  sudo yum install xauth

• Important: Reload ssh server:

  sudo /etc/init.d/ssh reload
