Open Stack

I've finished installing Swift on 6 EC2 nodes, but I'm struggling on this seemingly simple step:

http://docs.openstack.org/diablo/openstack-object-storage/admin/content/part-i-setting-up-secure-access.html


Some quick questions:

1. I'm probably missing something obvious but where do I get the "swift" tool from?
2. Also, do these below iptables look OK?
3. Finally, do I have to restart some service to have the new iptables read? 

Thanks,

Amar
