I am trying to connect to a remote CentOs machine through VNC to get a graphical display.
I have followed the steps mentioned in https://www.howtoforge.com/vnc-server-installation-centos-6.5 to install and configure VNC server on my CentOS machine.
I have used the Iptable command to open 5901 port as well.
However on my ubuntu machine when I type vncviewer and type my the remote server's IP address I get the following error:
main: unable to connect to host: No route to host (113)
