[opensuse] Playing with IPv6
With all this talk about IPV6, and today being a bit of a slow day, I thought I might play a bit with using 6to4 via 192.88.99.1. (we already have an IPv6 range, but unfortunately our Lancom DSL router doesn't speak IPv6 yet). So, I did the following: ip tunnel add tun6to4 mode sit remote any local 212.25.14.42 ttl 64 ip link set dev tun6to4 up ip -6 addr add 2002:d419:0e2a::2120:2501:4042/128 dev tun6to4 route -A inet6 add default gw ::192.88.99.1 I'm not completely certain what 2120:2501:4042 is, it seems to be a "coded" variation of "212.25.14.42" (I got it from http://6to4.version6.net) However, I must be missing something as I'm unable to ping an IPv6 address, e.g. www.switch.ch - I can see the echo request going out, but nothing ever comes back. What might I be missing? I have checked the firewall, it's not being dropped there. -- Per Jessen, Zürich (1.9°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Are you using "ping" or "ping6"? Also, a good site for testing is ipv6.google.com. You can also use the ShowIP add-in for Seamonkey & Firefox to see what address you're hitting. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

ping6 :-)

Thanks, I'll try those out. -- Per Jessen, Zürich (3.0°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Or a website from the other part of the world: http://www.kame.net/ Different view from either v4 or v6 It is bad that there is a dedicated ping6, traceroute6 or ip6table.

In principle you're right, but in practice "the user" will have little or no need for ping, traceroute and iptables. The network or system admin will not have an issue with ping6, traceroute6 and ip6tables. -- Per Jessen, Zürich (3.2°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That ipv6.google.com is IPv6 only, so you can't reach it, if IPv6 isn't available to you.

Those are tools used to test networking, so you have to be able to specify either IPv4 or IPv6 when using them. On the other hand, things like ssh and browsers use whatever address type is available, but generally prefer IPv6. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well, the point i was making, is that some commands/servicse are v4/v6 agnostic. You can force them with a switch on the cli, like -4 or -6. That is as it should be, keeping the difference at a minimum for "end users" I'm very glad that asterisk supports v6 since version 1.8, but a lot of work is still to be done. Openvpn (currently at 2.1) will release their support for v6 in 2.3, probably somewhere Q2 or Q3, so that will probably means that strongswan will get more attention, as they support v6 for quite a while. And there are other product that afaics don't make any effort at all, like mysql. Allthough one might debate that databases should only be accessed via link-local... hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

IPSec was originally developed for IPv6 and then applied to IPv4, so Strongswan had better support IPv6. I have used OpenVPN for years and am considering switching to Strongswan because of the IPv6 support and also because my Nexus One support IPSec and not OpenVPN. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi Per, I intended to ask this sooner, but time lacked. While I can find my way in IPv4, IPv6 is still dark to me. So do you have reference material concerning IPv6 or books you can recommend ? I found a book in PDF-form, but it dates from dec 97. Other material on the Internet is confusing for me. I found the books I looked at in the local computer-bookstore not good. I will do some research again though. This thread helped me somewhat : it made clear the usage of ping6.

Hi Koenraad Not really, but there are plenty out there from O'Reilly and others. I would do a scan for IPv6 on amazon and see what the most popular book is. -- Per Jessen, Zürich (11.8°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Wow. All the books in this area are outrageously expensive. You can tell they are all priced for a corporate expense account. -- Explain again the part about rm -rf / -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You are paying to have an author and the book printer and the distribution system do the work of doing the research and handing you the digested result. If people doing work in that field find the price of the book trivial compared to either not having the reference or having to pay an expensive employee the time it would take to get it the hard way, what of it? You are free to not pay them for that service and do your own googling the same as that book author did. The info is out there, the authors didn't get it beamed into their head from god, so what's the problem? If you want a thing, you either have to spend money, or spend time or effort. You want a thing without having to spend either? -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The books are overly expensive. But hey, thanks for rushing in and calling me a cheapskate without doing a bit of research. Averaging aroud 50 bucks for paperback, these books are well over twice as expensive as virtually any other computer topic books. Perl books are all around 30 bucks. C++ around 30, few outliers near 100. Linux Administration, under 30, couple outliers. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

One thing that determines the cost of a book is the size of the intended audience. A small audience means higher cost per copy. I have also spent more on some computer books. Also, when you look at price, you should also consider value to you. A good reference is worth a lot more than the pile of drivel that some books are. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

O'Reilly books aren't expensive* and they also tend to be very good. I guess you haven't priced college level texts, if you think O'Reilly books are expensive. That IPv6 essentials is $35.99 for the ebook, $44.99 for the paper version or $49.99 for both. You also get free ebook updates and they often have various deals to make the books much cheaper. *I recently downloaded their Asterisk book for free. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
