I getting below error when running xclock command to one RHEL 7 server

$ xclock 
PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused Error: Can't open display: XX.XX.XXX.XX:10.0

I did set below setting in /etc/ssh/sshd_config

X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost no

I have tried with X11UseLocalhost Yes or even with commented it out but no luck

I tried with setting ForwardX11Trusted yes in cat

/home/user/.ssh/config

I am trying to connect from putty which is on my window 10 laptop . I did below setting in putty while connecting sever

selected - Enable X11 forwarding
selected - Remote x11 authentication protocol as -- MIT-magic-cookie-1

But no luck with above settings

Due security restriction I can't download any software like xming in my window laptop , also I don't have any other linux server from where I can ssh this server

Its very urgent for me please help me

You do not have X server running. Check this error:

Can't open display: XX.XX.XXX.XX:10.0

So ask your manager to permit you to use external software. Or do the work with command line tools

  • thanks you very much for response !! Where I have to install x server ? In my laptop or in the server where I am trying to run xclock ?I have already installed xwindow in linux server – Newlinux-men Oct 01 '21 at 19:26
  • Because your display is your laptop you should install X server on the laptop. You do not need to have X server started/installed on linux to visualize X application on your laptop – Romeo Ninov Oct 01 '21 at 19:42
