      make sure you don't have iptables or any other kind of firewall running. Make sure multicast is part of your kernel.

       

      How can we check these details on linux box ?

            To check if iptables are running, use this command e.g. on fedora/red hat entperise linux:

             

            [rhusar@rhusar ~]$ sudo service iptables status

            Redirecting to /bin/systemctl status  iptables.service

            iptables.service - IPv4 firewall with iptables

               Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled)

               Active: inactive (dead)

             

            Turn it off by

             

            [rhusar@rhusar ~]$ sudo service iptables stop

            Redirecting to /bin/systemctl stop  iptables.service
