 Verify connectivity

We recommend that you verify network connectivity to the internet and among the nodes before proceeding further.

  1. From the controller node, ping a site on the internet:

    # ping -c 4 openstack.org
PING openstack.org (174.143.194.225) 56(84) bytes of data.
64 bytes from 174.143.194.225: icmp_seq=1 ttl=54 time=18.3 ms
