Hi @capsali , I followed your answer and also got the same error that @abhishek-talwar found, didn't find anything special in /var/log/keystone/admin.log and /var/log/keystone/main.log but found this line in debug mode: DEBUG (client) REQ: curl -g -i -X 'GET' 'http://ospoc-ctrl-node:8777/v2/..

I changed the vaule to dnsmasq_dns_servers = 8.8.8.8, 8.8.4.4, then did a # service neutron-dhcp-agent restart. It works - I can ping openstack.org now. Thank you very much!

@herrsergio nameserver 192.168.1.2 lies within the instance's /etc/resolv.conf (instance's IP = 192.168.1.3, instance's gateway = 192.168.1.1)

2015-09-22 12:51:10 -0500 asked a question Instances can't ping servers by their domain name

I followed OpenStack Installation Guide for Ubuntu 14.04(http://docs.openstack.org/kilo/install-guide/install/apt/content/ (http://docs.openstack.org/kilo/instal...)) step-by-step from chapter 1 to 6 (using neutron with 3 nodes).

However, after I launched an instance (chapter 12), I'm unable to ping http://openstack.org from that instance like the example in the 'To access your instance using a virtual console' section (http://docs.openstack.org/kilo/install-guide/install/apt/content/launch-instance-neutron.html#d6e4570 (http://docs.openstack.org/kilo/instal...)):

Verify the ext-net external network:

$ ping -c 4 openstack.org
PING openstack.org (174.143.194.225) 56(84) bytes of data.

rtt min/avg/max/mdev = 17.431/17.575/17.734/0.143 ms

Here is my result:

$ ping -c 4 openstack.org
ping: bad address 'openstack.org'

And I'm quite sure that I didn't miss a thing about configuring dns servers. Every hosts can ping http://openstack.org normally.

What is the result of $ ping -c 4 8.8.8.8 ?

2015-09-22 08:41:30 -0500 asked a question Configuring network component prerequisites for the compute node return errors

I'm trying to install Kilo by following this guide:

6. Add a networking component > OpenStack Networking (neutron) > Install and configure compute node

To configure prerequisites

Before you install and configure OpenStack Networking, you must configure certain kernel networking parameters.

  1. Edit the /etc/sysctl.conf file to contain the following parameters:

    net.ipv4.conf.all.rp_filter=0
    net.ipv4.conf.default.rp_filter=0
    net.bridge.bridge-nf-call-iptables=1
    net.bridge.bridge-nf-call-ip6tables=1
    
  2. Implement the changes:

    # sysctl -p
    

When I followed 2., these error messages appear:

# sysctl -p
net.ipv4.conf.default.rp_filter = 0
net.ipv4.conf.all.rp_filter = 0
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory

Do I need to fix this before proceeding? If yes, please help me.
