Can't open display in hp-ux 11.31

Hi,

 

On newly installed HP-UX server, cannot set the display for x windows, 

 

enabled X11 Forwarding in the sshd_config

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

XManager is installed on my machine, I can open xwindows on other servers but not this one.

 

Also, enabled X11 forwarding on Putty, set my Machine IP as the display address along with "MIT-Magic-Cookie-1"

 

Trying to start xStart session;

 

# /usr/bin/X11/xterm -ls -display $DISPLAY
/usr/bin/X11/xterm Xt error: Can't open display: %s

# xhost +
xhost: unable to open display "localhost:10.0"

 

# echo $DISPLAY
localhost:10.0

 

# xclock
Error: Can't open display: localhost:10.0
Error: Couldn't find per display information

 

Any help will be highly appreciated,

 

Thanks in Advance.
