you can ping them as in ping fe80::87d:c6ff:fea4:a6fc
ooh, I didn't know that worked. Same as ping fe80::87d:c6ff:fea4:a6fc%eth0 on my machines at least. No idea how it picks the interface when there's more than one. The interface seems mandatory for ssh for me: tim@einstein(4):~ (none)$ ssh fe80::1 ssh: connect to host fe80::1 port 22: Invalid argument tim@einstein(4):~ (none)$
