Solved it :). It seems that ping is firewalled for our local LAN. From: sylecn [mailto:syl...@gmail.com] Sent: Wednesday, March 05, 2014 1:42 PM To: Gnan Kumar, Yalla Cc: <openstack@lists.openstack.org> Subject: Re: [Openstack] unable to ping google.com
Hi, Have you tried directly ping 74.125.236.206 or 8.8.8.8? Have you enabled icmp in security groups? What kind of network topology are you using? YY Inc. is hiring openstack and python developers. Interested?
