Yeah, the real solution is like Felix suggests, to use site-local (or global) addresses instead of link-local. >>> Similarly, how do you enter an ipv6 link-local address in Firefox or >>> Opera? curl seems to accept such an address and return the proper web >>> page, but I can't find any interactive browser (graphical or >>> command-line) that will accept a link-local address.

I know MSIE on Windows does (since version 7-ish) and I think wget from Busybox does, other browsers/programs are hit and miss... According to RFC 3986: "A host identified by an IPv6 literal address is represented inside the square brackets without a preceding version flag. The ABNF provided here is a translation of the text definition of an IPv6 literal address provided in [RFC3513]. This syntax does not support IPv6 scoped addressing zone identifiers." Key being the last sentence. :) So, some browsers support that syntax, but it's not required. So I would not depend on that feature existing. Best to avoid using those addresses for web stuff if you can help it.
