Short of scripting your config on the Cisco, not really. (Yuck. I didn't just suggest that!) A solution would be to move away from using the Cisco as a tunnel endpoint and run something like CSELT's tunnel broker on a BSD box - dynamically creating tunnels as and when you need them. ... or use a different transition technique. 1 cent spent, Mark/ -- iam: networks and distributed systems From FRANCISCOD@advance.com.ar Tue May 2 14:43:37 2000 From: FRANCISCOD@advance.com.ar (Francisco, Diego) Date: Tue, 2 May 2000 10:43:37 -0300 Subject: Stupid question - need DNS?

I set up my cisco 2514 as my tunnel source. On my router's ethernet0, I subnet the assigned address to a /64 network. This network has two workstations. One of them is Mandrake 7.0 Linux. The problem that I am experiencing is on the Linux box 's eth0. For now I set up my router to send out a prefix-advertisement every 60 seconds and have the prefix valid for 360 seconds. When the prefix get expired, the linux box the releases the global unicast address and never re-acquires the prefix. So I temporary fix the problem by shuting down the interface and bringing it back up after the prefix expiring. This will make the linux box send out Neighbor Discovery messages and then get a prefix advertisement from the router. I would like to know if there is anyone experience with this kind of problem before? Thanks, Nattapong.

I cannot answer what Radu did to get his allocation, or who he got it from. Perhaps he means UUNET-UK, aka Pipex. UUNET-US was recently granted a pTLA allocation on the 6bone, and the proper contact for a connection through us would be email to ipv6ops@eng.us.uu.net. This is being done as a non-production service, and is not yet able to pass through any of the normal sales or support channels of UUNET Technologies, Inc. As an additional point of information, we haven't gotten the new address space allocation policies firmed up yet, and will need to finish that before we can make tunnels to "customers". That may take another week or two to be put into place. If you are looking for address space from UUNET-UK (riversoft.com is registered to a company in London, but you look to be west coast...) they can probably supply that in shorter term, and they do have an IPv6 router in the CA Bay Area... The contact for the ipv6 folks there is, I believe, ipv6@uk.uu.net. - Chris -- Chris P.

Is this plan reasonable? This is under discussion by the registries, and the outcome isn't clear yet, i.e., what to do in general for allocating public topology prefixes longer than /48 to smaller sites. Meanwhile, it is safe to say that your plan is ok if you consider your multiple middle schools one logical "individual organization", which is more likely to work for CERNET where you speak for the organizations from an Internet policy point of view, as opposed to a public ISP providing IPv6 service to multiple different customers (organizations).

I'm not sure if introducing "small sites" is a good thing... when we switch ISP and they force me to switch from /48 to /56, renumber becomes very hard. => the idea is that it is easier for someone which needs a /48 to deal with its ISP than for a common customer to fight in order to get a /48 because /64 is not enough: this is a compromise for common customers (ie you at home, IIJlab is strong enough to get a /x with x <= 48).

Message-ID: <009EA615.FA06CB56.10@cc.univie.ac.at> Hi Francis et.al., as I said a couple of days ago in Budapest, I would like to see an explanation and/or review from the routing point of view. Judging from my (limited) knowledge about IPv6, going for a variable length SLA field would either leave us with "wasted" address space (as the network next door would be a different site and thus should have a different NLA field anyway), or we would end up with a variable length network prefix length (much like in the v4 environment), effectively extending the NLA field into the SLA field. Doing so would probably require a cross-check against existing IPv6-aware IGPs. That is where I would like to see input from the routing camp(s).

I thought the point if IPv6 was to get rid of all this stingy political nonsense. I should have enough addresses to represent my internal topology. I should not have to pay or fight for them. PERIOD. Why is RIPE backpedaling from this? I do not want a repeat of our current situation, where American fools drinking cheap beer and checking their Hotmail accounts get service for $40/mo, and a small oppressed minority of technically creative people, who actually have such a thing as ``internal topology'' have to pay $140/mo for a connection of the exact same speed, just because we're not using the sealed web-box that The Corporation gave us. Who is proposing giving out /64's in exchange for money? I thought the (rather well-considered?) standard specifically recommend the Site Level Aggregator for the use of an ISP's _subscribers_. that part of the point of this ``standard'' was that it solved political disputes by dividing up the address bits and assigning them to each of the interested parties. no? Is there really an expected shortage of IPv6 addresses? Or is this all about people who say, ``but that seems like an awful _waste_ of addresses, 16 bits on someone with one subnet. We shouldn't give them out like that--addresses are precious.'' NO! Addresses _were_ precious. The IPv6 paper I read makes a great case for ``wasting'' addresses in terms of improved routing performance (addresses are more aggregateable) and elimination of special cases (NAT, proxy ARP). so, there are technical reasons subscribers should get the SLA, and no technical reasons that they shouldn't. I am confused as to where this strange address-mongering way-of-thinking is coming from. It sounds like IPv4-Think to me, and we don't do that here in the Brave New World. The only _political_ reason not to give subscribers the SLA is so that you can later sell it back to them for more money. It sounds to me like that's what's going on here. ISP's are attempting to design a profitable future pricing structure into the IPv6 standard, and protect their substantial existing revenues for selling hotly-contested IPv4 space to rich corporations. The standard as it stands takes a big chunk out of their pie--``yes, by all means, let's create a `small subscriber'--that way, we can charge for numbers, which are free, and make pure revenue. Any standard which throws us back to the old days of simply charging for bandwidth & rtt is unacceptable to us.'' >From The Case for IPv6: http://www.6bone.net/misc/case-for-ipv6.html Next level aggregators can divide the NLA address field to create their own hierarchy, one that maps well to the current ISP industry, in which smaller ISPs subscribe to higher level ISPs, and so on. This is accomplished by the further subdivision of the 32-bit NLA field (see Figure 15). Following the NLA ID are for <------------ 32 bits -----------> <--16 bits-> <---- 64 bits +-------+-------------------------+------------+-------------------+ | NLA 1 | Site | SLA | Interface ID | +-------+-------------------------+------------+-------------------+ +-------+-----------------+------------+-------------------+ | NLA 2 | Site | SLA | Interface ID | +-------+-----------------+------------+-------------------+ +-----------------+------------+-------------------+ | NLA 3 | Site | SLA | Interface ID | +-----------------+------------+-------------------+ Figure 15: Subdividing the NLA Address Space subscriber site networking information: Site Level Aggregator (SLA) and Interface ID. Typically, service providers supply subscribers with blocks of contiguous addresses, which are then used by individual organizations to create their own local address hierarchy and identify subnets and hosts. The 16-bit SLA field supports up to 65,535 individual subnets. -- Miles Nordin / v:+1 720 841-8308 fax:+1 530 579-8680 555 Bryant Street PMB 182 / Palo Alto, CA 94301-1700 / US From nsayer@quack.kfu.com Sun May 21 02:16:40 2000 From: nsayer@quack.kfu.com (Nick Sayer) Date: Sat, 20 May 2000 18:16:40 -0700 Subject: About address allocating References: <5536.958742783@coconut.itojun.org> <200005201317.PAA22880@givry.rennes.enst-bretagne.fr> <20000520134050.A24745@casey.Ivy.NET> Message-ID: <392738F8.16791D1F@quack.kfu.com> Miles Nordin wrote: > > On Sat, May 20, 2000 at 03:17:57PM +0200, Francis Dupont wrote: > > >is to introduce "small site" which get > > >/56 (on byte boundary, large enough for up to 256 subnetworks or > > >a few levels of hierarchy). > > > => the idea is that it is easier for someone which needs a /48 > > to deal with its ISP than for a common customer to fight in order to > > get a /48 because /64 is not enough: > > w.t.f.?

PERIOD. > Why is RIPE backpedaling from this? [I at first replied privately, but would like to gather public opinion too] I must agree, for anyone with fixed connectivity, even down to ISDN sorts of bandwidth levels, a /48 is the only fair thing to do. But I would like to inquire about providers of the bare-bones $19.95 (or free and add-sponsored) v.90 connectivity. The vast majority of these customers are connecting one computer to the Internet on-demand. Surely a /64 is good enough for them...? Who honestly believes that I need 65,535 subnets of 2^64 addresses to hook my laptop up to the net from my hotel room at USENIX? :-) In either case, the time to figure out what to do is now. IPv6-over-PPP surely will be a product on offer sooner rather than later.

But I thought the 128 bit address space was chosen to permanently doing away with having to beg for address space. I well remember the early discussions about IPng in which some advocated for a moderate, rather than a massive, increase in address space. They lost the argument. And I happen to be glad they did. With the address space available under IPv6, there is no reason whatsoever to not give everybody the address space they desire. Please, there is plenty of address space for everybody.

Let's not revisit > the pains of IPv4. Sure, but let's not swing the pendulum too far in the other direction. There are lots and lots and lots of ISPs that run small modem banks used by dial-on-demand analog users who get dynamic IP addresses. I'm one of them. Having every one of those providers having to get a /48 for every single modem they have is ludicrous overkill. The way the PPP RFCs for IPv6 read, the path of least resistance is to give each modem _bank_ a /64. The prefix is sufficient to route to a specific bank. The dialup link will provide its own EID, which has the added benefit of making hijack-by-connection-reuse less likely and means that such dynamic users who dial the same bank probably _do_ have a static IP address after all (since their EID is not likely/supposed to change). No, we don't have to be misers with v6 address space like we did under v4. And yes, I think that anyone with a dedicated link of any kind really ought to get a /48. Even dialup customers who do the dedicated-dialup trick ought to. But I have no problem drawing the line at on-demand-dynamic-dialup customers. Just because a resource is plentiful doesn't _require_ us to waste it.

There are really only two boundaries that are not flexible- the boundary between the format prefix and the rest of the address, and the /64 boundary. (The format prefix is in fact variable length, but it is architecturally defined.) So any IGP or EGP design needs to be fully flexible to the left of /64.

Yes, but there are other problems if you subnet to the right of /64 (autoconfiguration for example). I said tricky, not impossible.

(Which you might call a /128.) There has been talk of allowing (or disallowing) assignment of a single subnet (a /64) to a dialup connection. I don't recall any official position. And the real world being what it is, an official declaration would likely have little operational impact. But I think everyone involved in the IPv6 process would stand firm against the use of any prefix lengths in the range 65 to 127 inclusive *under format prefix 001 binary*, and against the assignment to a "site" or "organization" (whatever that is) of a prefix with length greater than 48. ______________________________________________________________________________ Matt Crawford crawdad@fnal.gov Fermilab "A5.1.5.2.7.1.

It depends on the address format. Not all format prefixes require the 64-bit interface ID field. Agreed that, in the global aggregatable format, subnet prefixes longer than /64 create problems. However, implementations should be kept unaware of the magic /64 boundary, as much as possible. (Obviously, the piece of code that does stateless autoconfig has to know about it, but certainly not any routing code.)

Even then, that's only 384 modems. A /64 should be sufficient for those. There are plenty of addresses for people who need subnets, and the management for each (single) modem is fairly easy.

The difference is, you are likely to ``find'' all those other servers using symbolic names. Especially when their numeric ``name'' is forty characters long, you will be inclined to deal with textual hostnames even if you are a sloppy and artless sysadmin. Therefore, you must find the nameserver before you go looking for all that other PeeCee Workstation nonsense. For example, on Unix when I boot diskless boxes I make sure they have a reslov.conf immediately so I can use hostnames in fstab. They need a nameserver even before they grab themselves an NFS server for /usr. The nameserver is different from those other servers you mentioned. I have seen some vendor Unixes that will even resort to setting their hostnames from reverse lookup records. Consider: 1) get local IPaddr with address discovery or some built-in IPv6 stuff 2) find nameserver using built-in mysterious clever scheme 3) perform a reverse-lookup to get hostname.domainname. Set the hostname and the 'search' domainlist. 4) default to well-known CNAME's: mail.domainname pop.domainname time.domainname Thus, there is a crude way of ``finding'' all these less important services, even without DHCP, given a way to automatically find a nameserver first. It isn't a particularly _good_ way, but it isn't a rediculous way either. It serves to demonstrate the ``specialness'' of the nameserver. While I lack the knowledge to comment on the worthiness of N. Sayer's specific scheme, it seems clear to me that giving the nameserver special treatment compared to other random daemons is a reasonable thing to do. Not necessarily desireable, but reasonable to a first order.

Even if you have to reconfigure your global names, it's major pain..... We had to change our domain master server some years ago and it took about week to get old address to vanish, for example. The problem at client side, I think, is choosing the right address to make connection with - if host has severall addresses - ipv4, ipv6 global, site local and link local, the client resolver must not resolve adresses whicha are clearly not reachable. I mean, if the target host is from different subnet, the resolver must not give me link local adress. If the target is from different site, resolver must not give site local etc. Just now I can configure my naming service to include all addresses and this will work as long as all hosts are reachable for all addresses.... but this all is for resolving names and connecting to host. name registering and related security is another issue... toomas -- HE: Let's end it all, bequeathin' our brains to science.

One egrgiously bad way to do it would be to start up an 'nmap' style scan of the local network looking for nameservers, etc. You could then keep track of the local services you need and press on out from there. Of course, DHCP6 would also solve the problem by providing all of that information. If we could autodiscover a local DHCP6 server, then we could query it for all of the services we'd be interested in.

So a cable modem should be fine. I use linux for my hookup to 6bone and it does the job well. To get a tunnel i suggest to look at www.freenet6.net, they offer tunnels to individual users and they provide a sample install script to configure it.. The drawback is that you have to request a new tunnel each time your ip changes.. Hope this helps..

I'm afraid this will degenerate into the usual Mac-vs-PeeCee style of useless war, but that's never stopped me before. One problem with making these (IMHO, rather important) evaluations is that they change from month to month as each project grows in the direction of their various goals. I get the impression that FreeBSD in particular has made a lot of recent progress. That said, from watching this list and keeping my eyes open for the last few years, I absolutely cannot recommend working with any experimental Linux feature. The project is too disorganized, poorly supported, and overburdened with people who ask silly questions on high-traffic mailing lists without reading any documentation first. Your best bet if you want an IPv6 Linux machine is to keep your eyes open at your local CompUSA for a box from RedHat or Corel or Caldera or something that says, ``New, Improved, now with IPv6 built in!'' in gigantic red shaking text next to a grinning stoned penguin. Buy the box, tear off the shrinkwrap, and read the 10-page installation manual. If you have any further questions, post immediately to your manufacturer's mailing list and request a private reply--there's no need to subscribe, because Linux support is excellent. The Linux community includes a band of enthusiastic knowledgeable ``volunteers'' who are happy to answer _all_ your questions. However, until CompUSA starts selling such a box, things are a little more difficult. You can make them easier on yourself by avoiding Linux for now. NetBSD is a good and all-too-often gratuitously overlooked choice. Their integration of the KAME code is the oldest, and is not surprisingly very, very complete. The project is lucky enough to include a few particular developers who have kept up a long-term commitment to get things resolved quickly and cleanly, and their progress has amazed me. I remember a certain Bay Networks wireless driver that got IPv6-corrected literally the day after it was integrated to -current, thus giving the NetBSDers at the IETF conference a working wireless IPv6 to show all their colleagues. :) Most of the NetBSD packages collection is IPv6-enabled as well. :' I don't even have IPv6 enabled on my system, yet: casey:~/work$ uname -a NetBSD casey 1.4X NetBSD 1.4X (CASEY) #8: Mon Apr 10 17:18:02 MDT 2000 carton@casey:/scratch/src/sys/arch/sparc/compile/CASEY sparc casey:~/work$ telnet ::1 Trying ::1... Connected to ::1. Escape character is '^]'. [...] This has worked for a very long time. :) > Linux is the easiest since so much code and information is available for it, I have not attempted a Linux set-up. However, I would advise against this path, and also this reasoning. First, why not the Linux path? Linux's integration of IPv6 is recent, incomplete, and spottily-maintained. Not so much for lack of effort, but just because it's really difficult to move in a consistent direction on that project without the active involvement of Linus or one of the wealthier distributions (meaning, RedHat). NetBSD (and FreeBSD) offers a complete IPv6-aware installation out of the box. With Linux, you need to tweak kernel parameters and integrate FreeSWAN code, all the while working against maintainers like Linus and distributors like RedHat who have higher priorities than integrating IPv6. n.b. a recent posting on this list, that the IPv6 module for Linux does not export/import the proper symbols, and therefore has to be statically linked into the kernel. That alone would be a problem not even worth mentioning, except that IPv6 was _offered_ to you as a module, so you have to stumble around and figure out w.t.f. is wrong, and the brokenness changes from one week to the next. In my experience, this is typical. BSD -current has far fewer of these problems, and that's probably just the tip of the iceburg. ex., ``What about Apache-v6? any one got an RPM?'' On BSD, already done. Intuitively, it's best to get a ``distro,'' as those crazy Linux kids keep calling it, with IPv6 built in. That means BSD. Now, on to the reasoning that led you to Linux in the first place. Your assumption that volume == quality is a dangerous one. One might convincingly argue that (a) you do not need ``much code.'' You need ``enough code.'' Given that Implementation X, Y, and Z all work and are complete, the one with the least code is likely to be nicer to use, configure, improve, u.s.w. (b) the reason you can count the amount of code available for Linux is that Linux has not integrated said code. You do not count the size of KAME on *BSD because it's already rolled into the OS. The fact that you have an ``amount of code'' to quantify is a bad sign. (c) Often I've found that the reason Linux has so much documentation is that it is rife with special cases, difficult to configure, varies tremendously from one installation to the next. Sometimes, the documentation is even sloppily-written ``HOWTO'' style script-kiddie documentation littered with the second person pronouns and ``okay, like...'' if not with 3's 1's ph's and z's. see http://crackmonkey.org/faq.html#ANSWER26 for a continuation of my hyperbole. I would not deny that Linux's documentation is among its greatest strengths. For example, Linux books have basically taken over my local bookstore. But, you should at least be aware of an alternate perspective. Note that the VAX and the AS/400 come with a lot of documentation, too. Once again, personally I prefer brief, consistent, and helpful, over long, whimsical, and condescending. > but you can prove me wrong. no, I can't. It's not _that_ unambiguous. I've told you what I know and what I think, and that's all I can do. If you're persistent, I'm sure you can get whatever system you want to work. You may have other issues, like for example you may know Linux better than you know any other Unix, or you may just plain like it. But, you asked, ``which is easiest.'' I've told you what I think is easiest. > How do I enable 6to4 support in Linux to work with a cable modem? We could really use a list archive or something--is anyone keeping one? Anyway, people ask your question at least three times a week, so please don't take this personally, but... Generally you can't get answers on this list unless you ask a question that proves you've already done some reading. The best answer you'll get to the question above is: see http://www.freenet6.net and http://www.6bone.org. I always feel bad saying that, because I'm not sure how you managed to find this list without finding the web sites and their documentation first. But, there's nothing for it: start reading and get to work.
