I've decided to try experimenting with IPv6. I can ping the interface on

something else required to enable this? Also, how does one get the apps,

tnx jk

Is anything else on your network configured to support IPv6? Do you have an
IPv6 router? IPv4 protocol stacks will not respond to an IPv6 ping (or
anything else).

It's just a local network. All computers involved are sitting on my desk, to there's only the switch to worry about. As I mentioned in other notes, the computers receive the ping, but don't respond. This is shown by ethereal. They do respond to their own pings. All systems are running SuSE 9.2 or 9.1, which support IPv6.

But are you sure your switch can handle the IPv6? If your switch is not IPv6 enabled, I doubt that you will get it to work.

To see if it is your switch that is causing the problems, you can try using a crossover cable to directly connect two of the computers directly, and see if you can establish some communication. If you can, it is probably your switch. If it is your switch, you can try to find a firmware upgrade that allows IPv6. Or put a second network card in each computer and forget the switch, but using a switch would be much easier to manage.

Switches don't care about IPv4, IPv6, IPX NetBIOS etc. They only forward ethernet frames, ignoring higher protocols. Also, the "Neighbor Solicitation" packet is being received at the destination.
