This is going off-topic, apologies. "Firefox does not appear to support IPv6 link-local addresses". I think I understand the issue perfectly well.
It has 45 entries. For instance: 34, 37, 29, 10, 17, 32
This morning, I did quickly peruse those comments - they are all from people claiming they _need_ this functionality. In my opinion, they are ignoring the real issue - a misconfigured ipv6 network. Until the network is given a prefix, e.g. 2001:db8:1234:5678, it really is not a functioning ipv6 network. Specifically for your printer issue: run a radvd somewhere, with this config (/etc/radvd.conf) : interface eth0 { AdvSendAdvert on; AdvManagedFlag on; AdvOtherConfigFlag on; too clients { fe80:: .... your printers LL; }; prefix fc00:1234:5678:9000::/64 { AdvOnLink on; AdvAutonomous on; AdvRouterAddr off; }; }; With this, your printer is the only device that is permitted to auto-configure itself. Permitting other devices would only cause problems when you don't have any real ipv6 connectivity. I am assuming your printer does not have any desire to "phone home". The minute you start radvd, your printer will auto-configure and assign itself an address on fc00:1234:5678:9000. Grab the LL address from the label, ignoring the fe80:: part and append it to the prefix. You can now access it from your browser: http://[fc00:1234:5678:9000:21e:bff:fe08:4ccb] Or you add it to /etc/hosts and use 'bilbo6': http://bilbo6 -- Per Jessen, Zürich (15.6°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

They need that feature in order to configure network devices to work in their normal network. They claim they simply can not access their devices for initial configuration as the only address on which they respond that they know about is the LL address.
Specifically for your printer issue:
run a radvd somewhere, with this config (/etc/radvd.conf) :
interface eth0 { AdvSendAdvert on; AdvManagedFlag on; AdvOtherConfigFlag on; too
clients { fe80:: .... your printers LL; };
prefix fc00:1234:5678:9000::/64 { AdvOnLink on; AdvAutonomous on; AdvRouterAddr off; }; };

The culprit was precisely that NFS saw the IPv6 addresses of host Telcontar, used it, and Telcontar nfs service went berseck. So I had to remove the IPv6 entries from both name services. Now I installed radv on Isengard.. I saw this in zypper output: Additional rpm output: Updating /etc/sysconfig/radvd ... created /etc/radvd.conf with ULA prefix fd91:e64d:a69a:0001::/64 What is that prefix?

Done.

Fyi, forwarding is usually enabled on a router, that's why it is complaining.

It might - as a dhcpv6 server. Yep, I think that ought to work fine.

Actually, there is more likely something wrong in the environment, nfs over ipv6 works fine.

Problem is, there is a dhcpv6 server on the router, I should not interfere with it.

Not on this machine. On the other, and days before, and on another mount. The entries are by IP, not name. But the entries on client fstab are by name, so it is possible it prefers to use IPv6, which the server nfs does not provide. Still, an error should produce an error and an abort, not thousands of log entries per second, repeated. The problem was from rpc services used by nfs. -- Cheers / Saludos, Carlos E. R.

Doesn't matter - your local network was fc00::, so trying to access a device on fc00:1234:5678:9000 requires a route.
