If «has a working ipv6 setup» means «has a address with scope better than $value», then yes, that's easy. See my other post to this thread. I think «has at least one IPv6 address configured» should mean «has at least one IPv6 address which may be in DNS configured». Yes, this probably breaks NAT-PT, this probably also breaks for people who want to talk to services on localhost using IPv6 (and doesn't otherwise have IPv6 configured) as well as people who put link-local addresses into DNS. Don't do that, then. IMNSHO. -- Tollef Fog Heen UNIX is user friendly, it's just picky about who its friends are
