If you encounter error similar like;
Can’t connect to display `unix:1′: No such file or directory at /usr/local/share/perl5/X11/Protocol.pm line 2264.
Do the following;
export DISPLAY=localhost:1.0
*If you install clusterssh inside Windows subsystem for Linux don’t forget to install Xserver and Xterm.
zypper install xorg-x11-server
zypper in xterm
zypper in xhost
