Can you provided the output of 'ifconfig'
on the hosting node? Also 'ps aux | grep dnsmasq' .

RE: [Openstack]
problem with metadata and ping
Hi,
So I added that rule:
iptables -I INPUT -i tap+ -p udp --dport 67:68 --sport 67:68 -j ACCEPT
but still the same problem.
There is another thing:

shows all the host and services. But in dashboard it only shows the services
running in aopcach.

Arindam,
Ooops, I had a typo. The command should have been: iptables
-I input -i tap+ -p udp -dport 67:68 --sport 67:68 -j ACCEPT
You need the iptables configuration on the system where dnsmasq is running.
It shouldn't be necessary in the compute nodes that are being booted.

Hi,
Thanks for your reply.
The dnsmasq is running properly.
when I tried to run iptables -I input
-i tap+ -p udp 67:68 --sport 67:68 -j ACCEPT
it says,
# iptables -I input -i tap+ -p udp 67:68 --sport 67:68 -j ACCEPT
Bad argument `67:68'
Do I have to do this iptables configuration in controller or in compute
nodes also.

Arindam,
I saw a similar problem with quantum. If you have iptables running
on the hosting system you may need to update the rules to allow the DHCP
Discover packet through: iptables -I input -i tap+ -p udp 67:68 --sport
67:68 -j ACCEPT
Also ensure that dnsmasq is running properly.

hi,
I was misled by this:

This is a nova-network problem.
