-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As Jorge was pointing out last week (https://lists.launchpad.net/openstack/msg04596.html), the problem seems to be iptables related. When I added these two rules, I was able to ping google.com with 10.0.1.1 as the nameserver.
# iptables -I nova-network-INPUT 1 -p tcp --dport 53 -j ACCEPT # iptables -I nova-network-INPUT 1 -p udp --dport 53 -j ACCEPT However, as soon as a new instance starts, these two rules goes away. # iptables -L nova-network-INPUT Chain nova-network-INPUT (1 references) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain I start a new instance, few seconds later: # iptables -L nova-network-INPUT Chain nova-network-INPUT (1 references) target prot opt source destination I also have these two rules: # iptables -L -n|grep 67 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:67 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:67 # iptables -L -n|grep 53 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:53 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 Can someone explain how these iptables rule get created? I thought these rules were generated by starting nova-network. I also saw this: https://bugzilla.redhat.com/show_bug.cgi?id=734347. Not sure if this is related. I am running RHEL 6.1. thanks. - --sharif - -- Sharif Islam Senior Systems Analyst/Programmer FutureGrid (http://futuregrid.org) Pervasive Technology Institute, Indiana University Bloomington -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOlJEsAAoJEACffes9SivFivEIAKA17GpyNWZb9cyvsJZhEyLL vdvbRH9ywYHR7GJtHcIt4GnH0jBWR6JbqfviuozIpyYg5f6FkFJ8N1rGUBWFVyE+ obb+fPofq7c5Kb9EbH19pKwkccjomNC55lJBZbX4UUzVsAtGubj3yWdwGeFVMyZX tUwyoylnY+PFE38rQ+FWjIBBPdmBkIRJrXmu9xSqKzYqDbJ3Z/5YLZwdc6dOC6le abchZkbYUI1tCEQoSJHnolzXbhXXoNDivdcqPKJRN2DbuWjvi+unE0yYBzAhtK8Y 1y+0DaJzCaDhNr0focz24fbEdXw/qDCdMm+BeerZSo9+WMV2zyeWhF7EdkO7w24= =BVdE -----END PGP SIGNATURE----- _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
