FreeS/WAN Project Bows Out 221

Posted by timothy from the ideas-don't-die-though dept.
V. Mole writes "After five years, the FreeS/WAN project has decided to end development. The main reason seems to be that although the project was technically successful, it was not making much progress with its political goals of encrypting a significant portion of all Internet communications, although one might guess that the selection of KAME for the standard Linux IPSEC implementation might also have influenced this decision. And don't panic, the software will remain available, and of course some other group is free to continue development."

          I have been doing crypto for a long time now. One of the points that Eric Rescorla raised with me when we were speaking at the RSA show was that more email has been secured with SSL in the first year of deployment than has ever been encrypted with S/MIME and PGP combined.

          We all screwed up, Bruce said so in secrets and lies, but he still only half gets it. Almost all the crypto 'truth' turned out to be bogus. End to end crypto is a crock for a start, especially when you try to retrofit to a legacy protocol.

          We spent years deplying S/MIME in almost every email reader, but we never made it easy to distribute certs. We also wasted time getting people to implement S/MIME when it would have been better to get them to start by simply not doing harm - if someone gets a multipart/signed message that they don't understand the mail reader should present the signed text without any complaint, just the same as any other unauthenticated content. Same with a message from a person with an invalid or expired cert.

          The big screw was messing up the policy aspect. We need an infrastructure to tell people the security that an Internet server supports. DNS is fine for this, as folk point out DNS is secure enough unless there is a pretty difficult active attack.

          My criticism of the inanities of the IETF wrt DNSSEC still stand. They just do not understand security there. it would have been better to have deployed DNSSEC with OPTIN two years ago than to continue to wait for all parties to agree on perfection.

    Dear FreeS/WAN Community,

    After more than five years of active development, the FreeS/WAN project will be coming to an end.

    The initial goal of the project was ambitious -- to secure the Internet using opportunisitically negotiated encryption, invisible and convenient to the user. For more, see our history page. A secondary goal was to challenge then-current US export regulations, which prohibited the export of strong cryptography (such as triple DES encryption) of US origin or authorship.

    Since the project's inception, there has been limited success on the political front. After the watershed Bernstein case, US export regulations were relaxed. Since then, many US companies have exported strong cryptography, without seeming restriction other than having to notify the Bureau of Export Administration for tracking purposes.

    This comfortable situation has perhaps created a false sense of security. The catch? Export regulations are not laws. The US government still reserves the right to change its export regulations on short notice, and there is no facility to challenge them directly in a court of law. This leaves the US crypto community and US Linux distributions in a position which seems safe, but is not legally protected -- where the US government might at any time *retroactively* regulate previously released code, by prohibiting its future export. This is why FreeS/WAN has always been developed outside the US (in Canada and in Greece), and why it has never (to the best of our knowledge) accepted US patches.

    If FreeS/WAN has neither secured the Internet, nor secured the right of US citizens to export software that could do so, it has still had positive benefit.

    With version 1.x, the FreeS/WAN team created a mature, well-tested IPsec VPN (Virtual Private Network) product for Linux. The Linux community has relied on it for some time, and it (or a patched variant) has shipped with several Linux distributions.

    With version 2.x, FreeS/WAN development efforts focussed on increasing the usability of Opportunistic Encryption (OE), IPSec encryption without prearrangement. Configuration was simplified, FreeS/WAN's cryptographic offerings were streamlined, and the team promoted OE through talks and outreach.

    However, nine months after the release of FreeS/WAN 2.00, OE has not caught on as we'd hoped. The Linux user community demands feature-rich VPNs for corporate clients, and while folks genuinely enjoy FreeS/WAN and its derivatives, the ways they use FreeS/WAN don't seem to be getting us any closer to the project's goal: widespread deployment of OE. For its part, OE requires more testing and community feedback before it is ready to be used without second thought. The project's funders have therefore chosen to withdraw their funding.

    Anywhere you stop, a little of the road ahead is visible. FreeS/WAN 2.x might have developed further, for example to include ipv6 support.

    Before the project stops, the team plans to do at least one more release. Release 2.06 will see FreeS/WAN making a late step toward its goal of being a simple, secure OE product with the removal of Transport Mode. This in keeping with one of Neils Fergusson's and Bruce Schneier's security recommendations, in A Cryptographic Evaluation of IPsec. 2.06 will also feature KLIPS (FreeS/WAN's Kernel Layer IPsec machinery) changes to faciliate use with the 2.6 kernel series.

    After Release 2.06, FreeS/WAN code will continue to be available for public use and tinkering. Our website will stay up, and our mailing lists at lists.freeswan.org will continue to provide a forum for users to support one another. We expect that FreeS/WAN and its derivatives will be widely deployed for some time to come.

    It is our hope that the public will one day be ready for, and demand, transparent, opportunistic encryption. Perhaps then some adventurous folks pick up FreeS/WAN 2.x and continue its development, making the project's original goal a reality.

      The real thing that bones up OE is that you need a static, public IP (since OE isn't defined for NAT'ed IPsec). If you want to do full OE, then you access to the reverse map too. How many have that? Well, if you don't, you probably don't have static IP or an AUP that even lets you sneeze.

      I don't think you're alone there. I myself have tried FreeS/wan several times over the years and have always found it a frustrating experience. I think the documentation should take a lot of the blame for the problem. It was never too clear and gave only a few wildly different (and sometimes conflicting) examples. Left side? Right side? They would often switch the left/right-side convention for no apparent reason. And it I found it wasn't always clear what configuration settings were required and how they interacted. Because of this it was hard to condense a working configuration out of the few examples they did give.

      Many years ago I was trying to connect my network with my familys' network (linux to linux) I eventually went with vtun [sourceforge.net]. It worked fairly well. More recently I went with OpenVPN [sf.net] when I needed to connect my dads' Win2K laptop back to the family network over a dial-up line. In both these examples I originally tried using FreeS/wan on the linux side(s). I thought it would be easier (especially with W2K in the second case) because IPsec is a standard. Nope.

    No I'm not trolling I'm asking a question here. Outside of admins, how many people really care whether their connection is secure or not. I always reference this out regarding IPSec and the likes, so I'll point out eBay as an example. Now a company such as eBay in my opinion should have SSL based log on by default, period. It's optional. Why? Because most users outside of the geekrealm, and system admin realm don't understand the escape key from their space bar. So when it comes to things like... "Will you accept this certificate?" and the likes, they don't know, and they certainly don't care. Same goes for VPN's. Why should the people care if Freeswan "was not making much progress with its political goals of encrypting a significant portion of all Internet communications" when the typical user doesn't know about Freeswan, and more than likely wouldn't care.

        Sure, it's not. Neither are locks on doors on houses.

        To secure your house, you must:
        1) Lock the door.
        2) Lock the windows.
        3) Notify your neighbors when you'll be out of town
        4) Turn on lights
        5) Turn on alarm system
        6) Lock fence gates ... etc...

        But HOW MUCH GOOD IS 2-6 IF YOUR FRONT DOOR IS UNLOCKED?!?!?

        Don't assume that SSL is all that's needed. But don't pretend that it isn't needed.

    to be learned here. The stated goal of the project was to increase the amount of traffic that is encrypted on the internet. While this does not directly conflict with the goal of making as much software as possible "free" (as in beer), it does set a different goal.

    Why the hell am I bringing this up? Well, one of the problems with FreeS/WAN was that it would not work with low-bit encryption. This was done to promote their political goal. But it also had the side effect of inhibiting adoption at the places where for whatever reason people had to interoperate with low-bit encryption applications or setups. The last time I checked (which I have to admit was over 2 years ago) the FreeS/WAN project explicitly stated that they would refuse to cooperate with anyone who tried "subvert" the project by building-in interoperation with low-bit encryption.

    So what is this lesson to be learned that I am talking about? When fighting an uphill battle (which a volunteer project challenging for-profit institutions always does), it may not be wise to make it more difficult for people on the sidelines to agree with your cause.

    Linux was built on much better technology than Windows (nfs vs smb, ext vs fat, separate windowing subsystem vs windowing system as part of the kernel, etc), but it didn't gain in popularity because it decided it replace all the Windows boxen. The technical decision was made to cooperate with them. The fundamental decision on priorities was to hold interoperability above politics. FreeS/Wan took the other road.

    • No argument on the other two, but I really want to know why NFS is better than SMB.

      I mean, really. From a personal file-sharing standpoint, NFS is retarded.

    As someone who's dabbled in FreeS/WAN and IPSEC, I think this may actually help IPSEC on Linux take off. There is now another prominent IPSEC implementation available: the one in 2.6. For a long time, FreeS/WAN was the only choice, and while it was quite good, it had some baggage: Due to legal and political concerns, it was maintained by a relatively closed team, it was never well-integrated into the kernel, and it didn't offer some of the "insecure" features some users wanted. I would argue it was destined to remain a fringe project, never attaining the community acceptance needed for real success.

    The 2.6 implementation is not as mature, but it has excellent success factors. It was written by an alpha kernel hacker, it's in the mainline, and it's open in the Linux tradition. An influx of former FreeS/WAN users may be just what it needs to work out the kinks. FreeS/WAN has done a great service, and is now doing another by throwing its momentum behind an implementation with better long-term prospects.

    I've been a Linux user for 10 years, and a Unix System Administrator for 3 years, but Freeswan was among the most challenging things I've ever installed. I found that nothing less than reading the documentation from cover to cover is sufficient to understand it. I'm not suprised that it never caught with any sort of mainstream. Don't get me wrong, I am all for the vision of a secure-by-default internet. But unfortunately, it's so tough to install that only die hard security buffs have the patience to figure it out. Where is the ncurses-based "kernel setup wizard" script with forward and backward buttons? A checklist-based helper to point out what is missing next in getting the damn thing installed properly? A webmin module? A gui based connection configurator, called, say, [g|k]freeswan-conf? ESR has it dead on: without a thick slathering of user friendliness, this sort of project cannot succeed on any widespread level. Them's the breaks. I wish things were diffrent, believe me.
    • Im in a similar boat to you, though with perhaps a little more profesional experience. I can't claim to have gotten through the documentation though.

      Security is directly related to the skill of the admin implementing it. The skill of an admin is directly related to how well that admin understands that tool.

Now, I will look at alternatives - lord knows they can't be any more complicated to configure that FS.

    As a long time freeswan user I have to say this sucks pretty hard. Having used isakmpd and racoon on openbsd and freebsd respectivly, I've always thought freeswan was easier to configure (but not always easier to get working)

    Hopefully openswan will be a good replacement :)
  • I've spent so many weekends playing with connecting FreeS/WAN to my OpenBSD router. Every time I'd end up with some insanely cryptic error message (on both ends, openbsd isn't much better). This weekend I downloaded KAME for the 2.6 kernel, and had it working within half an hour, including the time to recompile my kernel.

    FreeS/WAN is an unfortunate example of a project too focused on a far out goal (OE) to make the simple foundations work.

      FYI, most of the time when people say "SSL VPN" they don't mean at all the same thing as what Freeswan does. (OpenVPN is an exception).

      Typically, an SSL "VPN" is really just a web app that uses ssl between your browser and itself. It runs on a box on the private network, and provides file browsing capabilities, "intranet" access (e.g. an internal purchasing website), etc. But it doesn't let you encrypt your ping packets, since you're not even really connected to the secured network.

      I think the companies who created the thing called it a "VPN" because it was the buzzword, and not because it is at all a Virtual Private Network.

    And I can say that it the most obtuse, cryptic product I have ever had to wrestle with.

    There was absolutely no way that 'normal' users were ever going to be able to make use of this product for the 'opportunistic encryption' the project aimed for, I honestly don't think you could design a more opaque and confusing piece of software if you were actually trying.

    That being said, once you get over the configuration hurdles and realise you will have to employ script-based kludges to do simple things e.g. get it to route packets though multiple tunnels terminating on the same local IP address, it mostly works quite well.

    • Indeed. Left and right? Why not local and remote? Why didn't it support multiple subnets? I think it needs to be redesigned, with the config in mind. I couldn't care less about OE either - but I do want tunnels that I want setup to work, and work well.

    ... not making much progress with its political goals of encrypting a significant portion of all Internet communications ...

    Part of the problem with the FreeS/WAN group was that they DIDN'T WANT TO INTEROPERATE. Their attitude toward single DES was that they refused to support it because it wasn't sufficiently secure. As I recall, they wouldn't even accept patches that provided it as an ifdef with the default turned off. So, they were a pain in the ass to use for any serious interoperative commercial development, which obviously requires stooping to single DES.

    This quote from the FAQ at freeswan.org sums up their attitude regarding interoperability:
    "As we see it, it is more important to deliver real security than to comply with a standard which has been subverted into allowing use of inadequate methods."

    FreeS/WAN saw it wrong. Sure, single DES is not macho enough, but interoperating is pretty damned important, even if that means supporting a protocol that is beneath your 'leetness.
  • OE, or oppertunistic encryption, which is a good thing, in the sense of

    For those of you who say "freeswan was so hard to configure so kame's better freeswan sucks bla bla" or even "kame sucks freeswan is king because kame tools are hard to understand" I have this to say: IPSEC in general is hard to configure... you've got tons of different parameters, hash algs, enc algs, id's, tunnels, ah, esp bla bla bla and if you don't understand the protocol in general then you have no business saying either is hard to configure because you got lucky with one of them and it just worked and now you're married to it and consider it superior. I have used both kame and freeswan and can say with authority, hacking for weeks at a time on custom patchs for freeswan, that they are both good products. I LIKE freeswan more because of it's overall feel of higher quality for managing large numbers of connections and it's general tollerance of other devices that have slightly broken behaiour. For instance, you can turn off rekeying on a connection and let the other side always initiate keying. That is handy. Now I don't agree with their politics and I really could do without them -- I can't say that I much care. Freeswan, in the spirit of open source allowed others to modify it as they see fit. I DID, others did, it worked. Saying the project was worthless without really looking at what it's existance has done and only looking at the fact that some of the politics were bad is most disturbing. I would hate to hear even one of you say BSD sucks because of some configuration issue you had on 386 bsd back in the day.

    And just for the record, tail -f /var/log/auth.log is your friend, as is ipsec auto --status | grep connectionname | grep esp (shows active tunnels)... OH one other thing... if you cant figure out what the other side is configured to when it does phase 1 and phase 2 negotiation, ipsec whack --name connectionname --debug-parsing ; tail -f /var/log/auth.log to tell you EVERY SINGLE ipsec parameter the other side sends you.

    For those who hated freeswan because error messages sucked, try the above. For those who say it sucked because of politics, welcome to open source!

    To me it seems obvious that freeswan will still deployed and maintained -- it's just too good of a thing to let go. Try to think of this as a releasing -- openswan and the rest are not going anywhere. Freeswan's active development is done... since their main goal was OE. Since I didn't want OE, I don't care. It's not like freeswan doesn't support some IPSEC feature or that its behind the times. What else needs to be done? Maintenance I would gather .. for a plain old ipsec implementation, it's pretty much done so who can blame em!?

    Considering the responses i've seen here, it's going to be maintained. I'm glad we're in opensource land and I don't HAVE to use kame if I don't want to or have some reason where freeswan is slightly better for my situation.
