I would start with:<br>
* ps -efl | grep dnsmasq | grep -v grep - to verify that the dnsmasq
process is running, you can also check the conf file appeas in this
output<br>
* ip netns - to get the list of namespaces<br>
* ip netns exec <the_right_dhcp_namespace_name> tcpdump -i any
... - to look for the dhcp offer or arp issues<br>
* ping each other - instance to dhcp address, and vice versa (the
second one should be done from within the namespace)<br>
