I installed RC2 last week on a desktop just for the fun of it. There were a few glitches during the install process but overall it went well.
But I'm having an issue with IPv6 addressing. The install is on a large network that runs both IPv4 and IPv6. Something like 96% of the six-thousand or so hosts are fully IPv6 enabled. openSuSE has always worked well enough in this environment. Check /etc/sysctl.conf for net.ipv6.conf.default.use_tempaddr = 2
(or any value?) and report back.
I added the line, and it did change the ifconfig output, but I don't think it's working yet.
First, why are there two address with the first 4 fields being identical? The working system had only one.
As I mentioned in another note, multiple IPv6 addresses are to be expected. If your network can't deal with it, that's where the problem lies. You'll have the same issues with Windows 7. The first 4 fields reflect your subnetwork address. With IPv6 it is possible to be on more than one subnet at the same time.
Notice that the second entry has a fe08:43 as the last part of the address. The 08 and 43 are in the last part of the MAC address, but where's the 00?
The last 64 bits of any address derived from the MAC address contain 24 bits from the MAC (the manufacturer ID), fffe, and then the remaining 24 bits of the MAC. The first 64 bits of an IPv6 address denote your subnet address or, in the case of link local addresses, start with feff. There are other special address ranges.
I think the infrastructure scanner here looks for a match and if it doesn't find it assumes a private address?
That's what I suspect. Your network admin will have to fix that or expect a lot of problems in the future. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
