I’ve be going through some of the ipv6 howto’s and discover a need for ipv6calc to follow along with the lessons. Unfortunately there does not seem to be ipv6calc rpm compatible with opensuse 11.1. does anyone know of a substitute or a workaround. Thanks!

I assume you mean this one:

The ipv6calc Homepage

Doesn’t sound like it would be too difficult to compile from source or to run rpmbuild on the source tarball as suggested on the page.

But have you checked the Build Service? Maybe some helpful person has already built an openSUSE package.
