It's not a bug and man page ping6(8) mentions it: --------------- -I interface For IPv6, when doing ping to a link-local scope address, link specification (by the '%'-nota‐ tion in destination, or by this option) is required. ---------------
However the error message "connect: Invalid argument" (with no help) is very confusing and I believe many people need to google this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1075424 Title: ping6 does not understand IPv6 addresses To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iputils/+bug/1075424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
