Linux In A Box 73

Posted by CmdrTaco from the little-is-better dept.
Henrik pointed us to the Linux in a Box project, which is a bitchin' little project to create an inexpensive little Linux box: it boots a 2.0.36 kernel from a ramdisk, and it's pingable and Telenetable, as well as being usable as a Web server. Only for the brave of heart and willing to hack.

    Please stop using these nasty words on Slashdot. Sites like this that are child-accessible should know to restrain their content in the face of pending laws. How many times does it need to be told to people that content that is offensive to children needs to be kept away from them?

    it boots a 2.0.36 kernel

    On top of that, you go and influence these poor suggestable little children with thoughts of running an outdated kernel that is simply a security hole! How do you even dare? Would you allow your children to use NT3.5? Would you allow them to use an outdated kernel? Think, Taco, what about the children?

    The Linux in a Box project has been around for a long time. The new release is version 3, but there is quite a bit of information cached about version 2. The main differences between version 2 and version 3 seem to be that version 3 uses 10-BaseT (instead of version 2's 10-Base2) ethernet and version 3 has 4 megabytes of flash rom. Below are several Google caches you may find informative:

    The idea would be that everything is hot-swappable and come to life as soon as you've plugged it in.

    We have been Shipping PC-104 linux boxes for the past 2 years. All it took was a Slackware rescue floppy, a bootdisk and an EPROM burner.

    The procedure for making the EPROMS for the RTD PC-104 card [rtdusa.com] is as follows:

    1. Fire up the card with +5 and 12 volts
    2. Create a freshly formatted floppy with the included Datalight DOS 5.0 [datalight.com] on it. I know, it's sad but we had some DOS setup code for the card.
    3. Drop loadlin and the kernal You DID build a baby size kernal for this with initrd right? on the floppy
    4. Create a ramdisk on you development system to build the root image for your new card
    5. umount the ramdisk
    6. Set the ramdisk to zeros with:
      dd if=/dev/zero of=/dev/ram0 count=4096
    7. Make a filesystem
      mke2fs -vm0 /dev/ram0 4096
    8. Mount the ramdisk and copy your root filesystem in:
      mount -t ext2 /dev/ram0 /mnt
      cp -pxR /projects/snmp/root_fs/* /mnt
    9. unmount it again and squish it down with:
      umount /mnt
      dd if=/dev/ram0 bs=1k count=4096 | gzip -v9 > /projects/snmp/eprom/root_fs.gz
    10. Now, use sneaker net to move the floppy to the DOS machine running the RTD supplied EPROM image maker and tell it to make the entire floppy into an EPROM image .BIN file(s)
    11. Burn the files into EPROM, plug 'em into the card, apply power and open a beer as you watch Linux boot on a 4 inch card
    Have fun.

    If you have any intention of selling really lots of those units, you need to change your bootup, loading and configuration procedure rather drastically to:

    STEP 1: Connect unit to LAN through RJ45, apply power.

    STEP 2: Unit discovers all local networking parameters by snooping, configures itself as a webserver on an unused address of the subnet (snoop to see its advertisement), and everything else is configured up through a browser.

    STEP 3: There is no step 3, because *everything* should be programmable in step 2, including uploading kernels to onboard flash.

    Yes, I know that the reason PC-104 cards tend to be as dumb and old-fashioned as they were 5 years ago is because in theory every extra facility adds a fractional cost to the product, but I can't help feel that the accountants aren't factoring in the cost of people's time, nor the likelihood of increased sales if the item is massively easy to use.

    Off my head it costs $250 for parts - some (as in all) assembly required. A few days ago I inquired about a price for an assembled system, but I have yet to get an answer. Will probably be a while now that they got /.'ed.

    If you're into in-a-box stuff, like at what the CSimm [rt-control.com] (no affiliations) does. It's smaller (the whole darn thing fits in an old-style 30 pin ram-socket). Just bought two of those for running CLinux [uclinux.org]. They're pretty little Motorola Dragonballs (also powers the PalmPilot V series) with 8 Megs of RAM and 2 Megs of Flash and an ehternet chip. No sleep for me now :-)

  • Real time devices is the high price spread, they run around $500 for the processor card. WinSystems [winsystems.com]Sells stuff alot cheaper (Around $200 two years ago).
    remember, Slackware runs on a 386. There a probably a ton of 386/486 PC-104 cards out there that somebody wants to unload.
  • The "paperweight" idea may be cheap, but has the demerit that the resulting machine isn't small.

    Furthermore, it is not at all unlikely that something of 80386 vintage will seriously suck both for the purposes of servicing the LAN as well as for servicing a modem. On my newer (long retired) 80486 box, the UART couldn't cope well with a 28K modem; getting hardware for that now is liable to be a chore. Similar will be true for Ethernet; being limited to 10Base2 wouldn't kill me, as I use it to hook up my laptop, but a slow ISA card may actually hurt throughput.

    I don't think this combo would work out terribly well to service a DSL or Cable Modem connection...

  • Thanks. I've heard of the LRP, and looked into using it for our router/firewall here.

    That's a different beast, though. All of the firewalling code relies on routing. A packet exists on one subnet (on one interface), and if certain conditions are met, it will be passed through to another subnet (on the other interface). This is great, but I think it would be better if this could be done with a bridge instead of a router. A company with a class A/B/C network has to split their net into multiple subnets for a router-based firewall to work, but not for a bridge-based firewall.

    For some info on this technique, check out This link [bell-labs.com].

    Since a bridge looks like a wire to the outside world (it has no effect on the topology of the network), a potential intruder won't know whether their packet has hit a firewall or not. A bridge that rejects a packet looks like the target machine (behind the firewall) is physically disconnected from the network. A traceroute won't identify the firewall (since the packets don't have to go through an IP "interface"), so that makes it harder for someone to figure out what machine to target for an attack.

    I think that some of this functionality is available in the new 2.4x kernels, since they have disconnected the ethernet interfaces from the IP addresses (for other reasons). (This HOWTO [linuxdoc.org] has info on bridge/firewalling)

    The next thing to do is to actually give a bridge an IP address - the same address for either NIC. You'd still have to know which "side" a packet comes from, for the firewalling to work. Once you have this setup, you can contact the machine (if you know its' address), but it doesn't show up if you try to contact something beyond it. Additionally, you can do things like have remote users (whose IP addresses change each time they dial in) use your SMTP/FTP/whatever boxes by authenticating to the brigde/firewall, and having the authentication script add a temporary IPChains-like entry for the dynamic address. That fixes a lot of the problems with spammers using relay hosts. (yes, this sounds a lot like a slightly modified proxy server)

    Maybe this is a good separate topic for discussion on /.

  • That one looks good. I was not aware of it.

    Dear Linux Fellows

    I, Mikael Dich, the designer of the Linux In A Box microprocessor board, is pleased that the LIAB project has come up on www.slashdot.com! http://www.liab.dk has broken down due to the heavy load, so here is a little information:

    The board uses i386EX at 25 MHz, 4 Mbyte of FLASH, up to 64 Mbyte of DRAM (72 pin), 10BASE-T, runs on 9-24V DC or AC, 8 watt, 150 grams, 4*6 inches.

    I am cofounder of the company "LIAB Electronics I/S" which produces and sells assembled LIAB microprocessor boards. We deliver these boards complete with a CD-ROM, a Users Manual and a Hardware Reference. Price approx. $300. The CD-ROM contains all documentation, including sources for the bootloader, kernel patches, images for an inital ramdisc, schematics and plot files for the PCB. This documentation is free and everybody is free to manufacture their own LIABs. You may change the design and use it as you want. You may download pdf versions of the (draft) Users Manual and Hardware Reference on http://www.liab.dk

    The LIAB board now runs both version 2.0.36 and 2.2.14 of the Linux kernel. At least ten different extension boards have been designed for the 64 pins I/O connector: a 12 bit A/D card, a relay/optoisolated I/O card, an MP3 player using the STA013 MP3 decoder chip, an IDE harddisk interface, an HPIB interface and a floppy interface. We are working on an simple USB host interface these days. The board is considere ideal for educational purposes.
