It means you have no firewalling on your cluster. This is basically a local policy decision on your part. I know Linux admins who swear by iptables and would never run without it. I know other Linux admins who think it's completely unnecessary (and can be replaced with things like appropriate ssh host controls, NAT, switch-level policies, etc.). You should probably read more about firewalls and security and make a local decision for yourself. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
