Captain Crunch's New Boxes, Part II

micsaund writes: "It looks like the infamous Captain Crunch has been toiling away for 3 years on a firewall now known as the Crunchbox. It runs OpenBSD and is administered via a web-based interface. Steve Wozniak is quoted as saying it's 'next to un-crackable.' Check it out at ShopIP. The Register also has an article on it. As an aside, since the Linux Router Project (LRP) appears to have been sold-out and GnatBox is a tad expensive, is anyone aware of some kind of 'packaged' firewall with a slick interface available for free?" We mentioned Draper's venture into firewalls last year, but there's been some progress since then.

      His product is FREE though, you should just don your asbestos suit should you go looking for support. (View a few IRC logs etc. to get a feel for how "Dick" seems to view newbies and/or non-paying customers.)

      Well, I'm glad that you had nice experiences, but the general consensus seems to be that good support is a rare thing from Smoothwall (hence IPCop.org, I guess). They certainly carve bold new diretions for customers service! They'll swear at you, not answer emails, and not rarely answer specific questions (instead, cut-n-pastes are regular).

      I'm not willing to post my emails between the developers, I, and other people in the company. I really don't want to be hassled by Smoothwall anymore. The funny thing is that I'm quite sure I'm unidentifable in the masses of people who might say such a thing ;)

      (and this comes from a paying customer of Smoothwall Corp. - not a freeloader).

      I *strongly* recommend any other distro. I didn't think customer service mattered much until I found a bug in their product and wanted them to fix it.

      Yep, Morrell is definitely someone to watch out for. He threatens, harasses, and insults practically anyone that doesn't tell him Smoothwall's the greatest thing since using the GPL as a way to fork off to a commercial product after getting overenthusiastic community ego boosting.

      He's gone so far as to make legal quasi-threats against me and other critics of his treatment of Smoothwall users. He's driven away enough developers that the IPCop project was formed and seems to have done quite a good job at proving themselves to have intentions of being more than just another forked project. IPCop has performed just wonderfully for me since my abandonment of Smoothwall.

      • There have been no releases since 0.9.8 on 12 Sep 2000 (a year and a half).
      • The only news since then has been three seperate sponsers (Cyclades, VA, and Sangoma). It's not clear what the money is being used for.

      linuxrouter.org is no longer the center of "Linux-firewall-on-a-floppy" development. It's been seldom updated for several years now; the only important thing on it being the mailing list. The site even apologizes for its own lack of maintenance: Unfortunately most all of the LRP docs at this site are painfully out of date. The LRP still is the basis of most Linux floppy distros, albiet heavily modified.

      Instead of linuxrouter.org, the real hotbed of development these days is the LEAF site, LEAF standing for Linux Embedded Appliance Firewall. The steinkuehler.net site you mentioned is a part of LEAF, hosting the Eiger/Dachstein distributions. Unfortunately the linuxrouter.org project doesn't point the way to LEAF. I only found out about it by following the mailing lists.

      I wrote what was once widely appreciated as the most useful howto for using LRP. It is now woefully out of date, and I recommend Eigerstein or Dachstein, which are so well-designed that they don't need that kind of detailed documentation.

      I can shed a little more light on the middle-recent history of LRP and LEAF. Two years ago, LRP was indeed the center of all linux floppy firewall/router activity. However, people were starting to innovate, and Dave Cinege (who owns the domain name) never seemed to find the time to update his own work or incorporate that of others. It was a running joke on the mailing list. It would not have been much work for Dave to at least put up links to the sites documenting and extending LRP, but it never seemed to happen.

      For a while, linuxrouter.sourceforge.net (now changed to leaf.sourceforge.net) was a repository of all the extra work. Before that everything had been on a crazy collection of obscure personal websites (like mine).

      Dave promised major updates to LRP, and then gave up on LRP and decided a completely new, cool project was necessary. This was around the time Tim McVeigh was executed, which Dave considered the murder of a hero or prisoner of war. Without getting into politics or morality, I merely note that it was the last straw for many people, who made a complete split and formed LEAF. I presume it was the rancor behind this split that keeps Dave from mentioning LEAF on his website.

      Unfortunately, if you type "linux router" into Google, LEAF shows up way down the list -- maybe 20th.

      IMHO, the people working on LEAF are dedicated and impressive. It remains far and away the best floppy-based router/firewall available. It is certainly the most actively maintained.

  12. Summary of mentioned firewalls, and a question by Anonymous Coward · · Score: 5, Informative
    It looks like a lot of the Linux-based firewalls I've seen recommended here use ipchains with the 2.2 kernel instead of iptables with the 2.4 kernel. As far as I understand, this would mean they can't do connection tracking for things like FTP and IRC. Here's what I'm able to figure out so far...

    Firewalls using iptables with 2.4.x kernel:

    Firewalls using ipchains with 2.2.x kernel:

    Firewalls using ipfwadm with 2.0.x kernel:
    • Freesco: ipfwadm, 2.0.38 (!)
    • FWTK: Dunno, looks old, mentions ipfwadm

    My question is, isn't it best to use an iptables-based firewall on a 2.4.x kernel instead of an ipchains- or ipfwadm-based firewall on a 2.2.x or 2.0.x kernel? I definetely want the connection tracking capabilities in the 2.4.x kernel, especially for screwy things like FTP, IRC, etc. (Yes, I know there is an IRC connection tracking patch out now for 2.4 kernels...) Is a kernel that doesn't support connection tracking for firewalls a reasonable option these days?
    1. Re:Summary of mentioned firewalls, and a question by GlobalEcho · · Score: 4, Informative

      Linux firewalls and NAT routers were able to handle FTP and IRC at least as far back as the 2.0.x series kernels, using kernel modules that I assume basically forced state tracking on these types of connections. Other modules handle all the other major protocols like this (e.g. RealAudio).

      LEAF/LRP/Dachstein do so automatically. I assume most if not all of the others you cite do so as well.

      So, to answer your question, the answer is "no". Lack of support for connection tracking is indeed unacceptable. But 2.0.x and 2.2.x have tracking after all, at least where it matters.
