[Dnsmasq-discuss] Permission issue with dnsmasq

[Abhishek Chanda]

Hi all,

I'm trying to run dnsmasq as part of openstack neutron. It fails with
a permission denied while trying to create the pidfile. Root user does
have permission on the directory where it is trying to write.

cloudscaling at mngmt2:~> ls -la
/var/lib/neutron/dhcp/312c528b-7ca2-42f1-a9b0-a15d7a0d7571/

dnsmasq: failed to open pidfile
/var/lib/neutron/dhcp/312c528b-7ca2-42f1-a9b0-a15d7a0d7571/pid:
Permission denied

I changed the permission of the directory to 777 and still got the
same error. What can be the issue here?

Thanks
