      33Mhz, 32Mb and a 250mb HD for my debian web server. It's served about 320mb in 24 hours (across a slow-arsed outbound link unfortunately) not long ago and took things in its stride. RAM usage hovers between 8 and 15mb.

      Of course, I do go and post links to it here don't I :).

        33Mhz, 32Mb and a 250mb HD for my debian web server.

        I recently installed Debian on a similar but lower-memory system (8MB) as a web server (yes, I am going to add more memory soon). Aside from a memory-intensive stage where apt-get was merging some package data, it went smoothly but slowly.

        The reason I mention this is that I've seen posts where people say they installed a small linux system on a computer with 4mb of memory "a while ago", and posts where someone has recently installed a small linux system on a computer with 16mb of memory or so, but no mention of really low-memory systems. So I figure that I should mention that a reasonably up-to-date distro (Debian) does install on 8mb, though it'll get ugly at one point if you don't have more like 16mb. Also, perhaps the 4mb Laptop How-To [tldp.org] is worth mentioning at this point.

        120 MHz K5, 32 MB RAM, 3 GB Hard Drive. OK, I regret using such a large hard drive for this...

        The real impressive thing isn't the low hardware, it is the fact that I run TinyDNS as my external DNS server on it, use SSH for remote access (only from the internal network), handle log-file parsing and management, on the box (in the middle of the night), and many other tasks. In fact, I could do all this on a 80486, but the RAM is the big commodity with all these things. But additional performance tuning will help. Additionally it is running FreeS/WAN though we will eventually be setting up a virtual router behind the NAT for handling GRE-tunneled IPSEC between offices ;)

        In fact the thing is so highly automated I sometimes forget that it is in the corner (reports of activity are happily directed to me every morning and I don't have to access the box myself).

        Had almost 90 days uptime when I had to replace the CPU fan. Now I am thinking about drop-in redundency ;)

      That's a pretty broad generalization to make. You may not need a lot of computing power for a 10 user file server (and anyone who says you do is a total moron) but there are applications for which you do need a lot of power.

        How about for a 4-person fileserver?

        Had an AMD 386DX40 box, 20MB RAM, 40MB HDD running Slackware 8. Managed to strip the install down to a hair under 20MB with a few system tools, Apache, Sendmail, and a couple userland goodies like PINE. It was running as households' gateway/firewall box to a 512k DSL hookup. Worked pretty well... max uptime was about 6 months (I was out of state for most of that time).

        Eventually added another harddrive and turned it into the household MP3 server as well. Worked fine most of the time =)

      Not entirely true, but that's close to what I believe.

      I had an old P5-233/64M/SCSI system for an office fileserver. Upgraded the SCSI system to UW2 hardware RAID5 and had all manner of problem. Turned out that the TX chipset couldn't handle the newer PCI bus master. There's now a P2-233 in there but the bandwidth utilization graphs seem to indicate that the CPU is still the bottleneck (the LAN isn't saturated, and the sustained disk I/O could bury the LAN several times over). I think samba is having trouble keeping numerous smaller feeds open than one or two big pipes. Oh well. :-)

    run feather weight Linux on my brand new hardware. Imagine how fast that would be !!!
    • I don't know, uClibc is supposed to have "made compromises" to get compactness over speed. I don't know whether this means using O(cN) where c is a bigger constant over an O(N) time algorithm or whether they went and used O(N^2) instead of O(N). I'd have get off my arse and read the source to tell you for sure.

      anyway, if you have a fast machine, you probably would be better off using the algorithm which, say, has more instructions to keep you doing calculations in the most time efficient way than bottlenecking yourself to give you a few kb more available ram.

      Then again one of Gordon Bell's laws says that "the simplest way to program something is probably the fastest" so go boot up a featherweight linux on your box, benchmark it and post the results to slashdot! You'd probably make the front page.
    • Imagine how fast that would be !!!

      Well, just pull up a console, kill all your services and boggie. It does make a difference. Your nasty math problems will be able to suck up all your memory and little will interrupt. You can go down from there if you wish. Boot up with grub to ye new Spartan kernel, and define a run level that's just like you want it and kick some ass. Spend a few more bucks to set up as many machines as you have projects. SSH into it to start your problem and then get your answer.

      Pitty all OS are not so easy to configure. You want more, you got it. You want less, OK. You want to throw everything you got at one thing, go for it. A box that you have to leave your chair to mess with is a pain, and should be fixed with a new OS.

The greatest service you can do to your general knowledge of all things computing, is use a broad range of machines/interfaces outside your common experience.

      It handles my light website traffic (a few thousand visits/day) with Apache/PHP/MySQL, and runs Squid, ProFTPd, Qmail, JabberD, and Samba for fileserving to the network... plus whatever I want to do at a console. And it barely breaks a sweat.

      I just ran into this on a P60 with 40mB RAM. Try turning off the remote checks. Also, if you're running Exim, there's a setting to control how many simultaneous messages it tries to deliver. Each time it attempts a delivery, it forks a Spamassassin. Try searching Google groups for "slow debian spamassassin" and see what you get.

      First you have to understand that the main design goal of glibc is code bloat. (I'm not kidding, static hello-world.c is >100KB). A lot of this is because glibc tries to support a large API, most of which is never used by most programs (e.g. locales). Also, glibc tends to lump lots of stuff into individual object files, so the linker does a worse job of discarding unused code. (the first call to printf() in your program pulls in tens of KB of stdio code)

      The concept of uclibc and dietlibc is to support the 10% of APIs that 90% of programs use, and to behave better with static linking. uclibc makes some sacrifices to work better with glibc-based software (I don't have exact numbers since I don't use uclibc). dietlibc goes completely to the extreme; anything that can be cut is cut, and object code is carefully divided so that static executables only include the code they really need.

      For concrete examples, see the static binaries compiled by dietlibc's author at ftp://foobar.math.fu-berlin.de:2121/pub/dietlibc/b in-i386
      (cat is 3KB, tar is 63KB, the thttpd web server is 42KB - add them up and you are just about equal to hello-world.c with glibc). Compare these with the sizes of even dynamically-linked glibc binaries on your own system.

      The reason you wouldn't want to use a cut-down libc for something like Gnome or KDE is that you'd have to recompile your entire system, including the X libraries and all other dependencies. (you can't use your existing X libraries since they are already linked to glibc). Along the way you are sure to run into one or two obscure C library APIs that only glibc implements.

      I think eventually there is a chance that glibc will be replaced by one of the cut-down libcs. The degree of bloat in glibc is simply obscene, and on top of that there is the backwards-incompatibility problem. (many packages broke during the transitions from 2.1 to 2.2 to 2.3, which should never have happened with a stable thing like the C library). Linus himself has even floated this suggestion on the LKML. The question that remains is whether the full glibc API can be implemented without creating another bloated monster. (there is no real alternative, since glibc's API has been enshrined in the LSB already...)

      On a similar note, I'd love to see GCC drop the problematic GNU STL for STLport. In my tests STLport has about half the cost in compile time and code size...

        Okay, and how big is dynamically linked hello-world.c? There aren't that many reasons to statically link a program. There may be some on reducing program size, but I would think Emacs and OpenOffice and Mozilla - the many megabyte executables - would be much more interesting than 100KB.

        most of which is never used by most programs (e.g. locales).

        How do you measure that? Every program that's not a server needs to be using locales; returning localized messages and sorting information the way the user would expect it are two big things.

        The degree of bloat in glibc is simply obscene, and on top of that there is the backwards-incompatibility problem.

        What exactly is an obscene amount of bloat? I have QT, GTK, 3 KDE libs and 2 Mozilla libs loaded into memory, each of which is larger than glibc. Why should I worry about the 8th largest library open on my system?

        The uclibc people understand that they were trading speed and standards-complance for size, and know that it's not a good tradeoff for everyone. Do you really understand what tradeoffs were made in glibc, well enough to make a better library?

        The reason why there's the backward compatibility problem is two-fold; first, people keep trying to link directly to glibc's internals, and not changing those would be a pain, and second, you want to make major improvements, but changing the libc major number is a flag day, so they try to support old stuff while making major changes, with some success and some failure.

        The question that remains is whether the full glibc API can be implemented without creating another bloated monster. (there is no real alternative, since glibc's API has been enshrined in the LSB already...)

        There is no real alternative, because most of glibc's API comes from POSIX and Single Unix Standard (SUS), or from traditional BSD functions.

      So why wouldn't I want to use them?

      Glibc is optimized for speed and standards compliance. It's also what Gnome and KDE and everything else on Linux is tested with, and has vastly more testers. I had 128 MB of RAM on this box when I bought it four years ago, and it wasn't top of the line. What's a half of MB of memory, especially as it cost me less than $50 to upgrade it to 384 MB?

      I just ran memstat on my box. I'm running a konsole, and mozilla and emacs. Glibc is pretty far down on the list of memory wasters. Mozilla takes up 22 MB; xfs 15 MB; QT 5 MB; Emacs 3 MB; bbkeys 5 MB (I smell a memory leak); libkio 2 MB; 1.2 MB for each of libgtk and libkdecore. Deep down in this list is glibc, taking up just over 1 MB. If you're going to be running Gnome and/or KDE, glibc is not your memory waster.

    A lot of the thanks should go to the work by uClibs and Busybox maintainers. Trimming the kernel is important, but the big savings in size is indeed the small footprint of the C libraries and the "combined" busybox binary.

    How much space saving? Well, at my work, we initially prototyped some programs that ended up at around 1 MByte, statically linked to glibc. The same program was 120K after statically linking to uclibc, and then 35K after dynamic linking to uclibc.

    I know there's various individual efforts out there to re-build Debian around uclibc. Imagine being able to put a full-featured Debian package on a business-card-sized mini-CD's that you can always keep in your wallet!

    I spent several months with a small group of people putting together an embedded system, which used both uClibc and Busybox. While these are undoubtedly excellent pieces of open source software which are great for embedded systems, I find their use questionable for everyday desktop computing.
    For example, many features you take for granted, say, with bash (such as compound commands, the full featured command execution environment) are not available with the smaller, simpler shells in Busybox.
    The small size does come at a price... after all, the reason they are smaller is because along with the bloat, some of the less frequently used functionality has been removed.

    ...a mint condition IBM ThinkPad 755C... On the resource side, I had 12 MB of memory and a 540-MB hard drive to work with...I planned to use the laptop for writing and for remote access to my more powerful desktop development system. Therefore, I needed a system with network support, a shell, a text editor like vi, CVS for versioning my documents, and SSH for secure remote access.

    Huh? Those are really light requirements and with some additional RAM, that laptop could run X without a problem. Debinate it!

    My 760LD has only 24M of RAM. It felt a little crammped with the 800 MB hard drive that came with it, but the only thing tedious about the installation of 2.2 potato was making the base install floppies. Once that was on, I could put the CD ROM in and zippy, no problem. The same har drive then worked with a much older Toshiba 468 with 8 or 16 MB or RAM. Yes, it does ssh. I got a bigger hard drive to feel less cramped and get more window managers. Using OLVWM I was able to make it display more than 256 colors, but it was stable with all the window managers I tried was stable with 256 colors. I probably boned up the ammount of RAM the card actually has, or missed some kind of shared memory thingy, shrug, it works.

    For the lighter requirements this guy has, he should have loads of extra space and it should work just snappy. My 486 gateway runs a little ftp, ssh and most of the standard distro. It takes less than 150 MB of system files to do that, leaving 350 MB for temproary files.

    Indeed, this fellows low expectations for his hardware should make the insalation much easier. I recenlty built a debian box on a 33MHz 486 with 8 or 12 MB RAM. It was painful, but you can just drop your hard disk into a nicer box and just put on the few things you want from a vanilla i386 binary install disk. If all you put on is i386, just put it all on in something with a little more RAM and pep, then drop it into your target. The kernel should adapt to it's new environment.

    Apt-get upgrade was a little painful last time, with the new OpenSSH stuff but it did, finally, work. I had to manually dpkg the new packages and read the error messages and it took a day, grrrr! I should have left it alone, but I'm glad it's done.

    Oh well, the man's effort is not wasted. His site is great for those who wish to really cut out the fluff and have a beautiful Spartan install. For the rest of you, I recomend the much easier Debian apt-get path.

    Hey, all, just to put this in context, I've been collecting some very old Itronix Mil-Spec laptops recently (one survived being thrown full-strength by me, a 285 pound ex-marine, from seven feet onto worn-out carpet over plywood, and booted up no problem) because I have a fetish for such things. Let's just say I have a thing for durability. The only problem is, the laptops have a "full environmental seal" which means no cd-rom, no internal floppy, no usb ports, etc. They only have a parallel and serial port, a phone jack, and a PCMCIA port protected with a cast aluminum door and a gasket. My weaker ones have eight MB of ram each and are only 486DX2-50's, with a 260MB HDD. My three stronger ones are Pentium 133's with 32MB of ram each, and about a 1.3 GB disk, with monochrome LCDs. Only one has color, but that one's just a 640x480 LCD. I wanted to run Linux, and not some quirky, doofy ancient Linux either. Here's how I got it to work.

    Step 1. I have an external floppy that connects to the PCMCIA slot, and a parallel port zipdrive. So, I downloaded Zipslack (available on the Slackware website) and the companion, fourmeg.zip, which creates a swap file. Zipslack is interesting because it creates a UMSDOS slackware installation on a zipdisk (just unzip it to the zipdisk). This can then be booted from the zipslack boot floppy (boot from the boot floppy, then direct root at /dev/sda4, i.e. the zipdisk). Zipslack booted with only minor difficulties -- I had to tweak a couple of BIOS settings, that's all.

    2. Once in Zipslack, I had to set up the Itronix's hard disks for Linux. So, first, I fdisked, and set up most of each disk as a type 83 Linux partition, and the rest as a type 82 Linux swap. I probably gave too much swap; I took a guess for the "big" ones and made it like 88 cylinders; I think it turned out to be better than 128MB (I made it a LOT smaller on my little ones). Next, I formatted the disk: I ran the command:

    "mke2fs -L armadillo -c -c -j /dev/hda1"

    This surprised me a little, pleasantly: I knew the two "-c" params would cause it to overwrite the disk with nulls, but it did it FOUR TIMES, which is pretty damn thorough. Once that finished up (it took at least an hour on my old machines) I mounted the disk as type "ext3" on /mnt/hd.

    3. Now, I copied my entire root directory onto the mount point, leaving out the loadlin stuff and files that were obviously DOS related (like the DOS mount directory). I copied each directory using (for example) "cp -a /bin /mnt/hd/bin". Of course, I didn't copy /mnt or /proc. For those, I just mkdir'ed them in the new directory. Once I was satisfied that the entire zipslack system was copied over to the new partition, I edited /mnt/hd/etc/fstab and set up the "/" partition as /dev/hda1 (and set up swap as well, although I wasn't sure I had to do that). Then, I rebooted using the boot disk.

    4. This time, I pointed the root directory at /dev/hda1. I booted into my hard drive's Linux, and ran liloconfig to set up automatic booting with LILO. I ran it in expert mode, and set up only one entry, i.e. that for Linux. Then I set it up to automatically boot into that entry with no delay.

    The result is that my little Linux machines all work perfectly!

    On my "big" ones, I put a bunch more stuff in. I put in the development disk set, plus x, xap, most of n, and this coming week I'm adding kde and gnome. On my "little" ones, I've only got 260MB of space, so I'm going to stick with text-mode. I'm toying with the idea of using emacs as an environment for those, IF the e set will fit on 'em of course.

    The most expensive of these laptops was 150.00. The cheapest was 25.00. Zipslack was free. Now, is that a great deal or what? Especially considering they're like indestructible little armadillo monsters, right?

    Oh, by the way: I'm using Zipslack 8.1 and I'll probably upgrade to 9.0 when it comes out. Gotta love Slackware! Bob RULES!

    BTW: my grammar isn't so hot today. It's the Marine Corps Birthday (10 Nov) and the "Marine Corps Drink" is the Rum and Coke, so cut me some slack there (ha! get it? SLACK! I slay me)... ;P

    FreeBSD works great with minimal hardware due to the absensce of bloatware on most modern linux distro's. The Bsd daemons like inet are much less resource intensive then their Linux counterparts. By default FreeBSD only has minimal daemons running.

    Gentoo may be another option due to its liteness upon default install. Everything and I mean everything must be configured and installed via "emerge x". This is also the downside. IF you have a slow 386 and a 28. modem for an internet connection you can expect s several day installation.



    NetBSD seems popular with many users with old machines like ancient macs. It may be more minimalist but I have never used it. Perhaps someone who has could care to comment. I like FreeBSD because of the excellent book that comes with the box set which will be helpfull since you will not have any of the gui point and click utilities like anaconda and yast2 to setup your 386.



    I like Linux myself because I am use to the SYSV init. I do not wish to start a flameware but FreeBSD is great for minimal installs and come with the best console documentation. It has its uses and if your use standard free software like sambe or apache, then a *BSD variant or Linux one wont matter.

    I'm highly amused by some of the comments in this thread; from my own perspective anything better than a P100 w 32M ram is a perfectly acceptable system. My main machine right now is a P166 with 64M and as well as using it for browsing, programming, etc it provides NAT, DNS, dhcp, apache.. I'm planning to upgrade sometime (probably to a P233, I had one last year but it died :( ). I'm in no hurry; this machine does everything I need for now.

    My first linux machine was a 386 with 4M ram. I had to upgrade to 8M fairly quickly because it would totally thrash when I tried to compile the kernel (or almost anything else bigger than hello.c) and I couldn't run X at all until I got a 486..

    Until recently, my main machine was a 486/66 with 20 meg of ram. On this, I ran some 20 operating systems.

    One of these was a version of OS/2, complete with gui, 4os2 and cdburner, that lived in 10 megabytes.

    The installation was not hard - sysintx and rar did it.

    So I could use the main version of OS/2 without having to worry about chewing up memory for the cd-burner. OS/2 breaks the 504 barrier for HPFS partitions. So does Linux, and Windows NT, the former installed but never booted.

    OS/2 has a considerably smaller footprint, given that a lot of it can be installed on another drive.

    The idea of having a small footprint is not bad at all. You can make a boot cd that runs the desired OS off the cdrom and ramdisk. This is how eComStation installs.

    In fact, the notion of one OS for all tasks is quite unecconomical, especially if the machine is to run unattended, or in a specific activity.

    You can burn cdroms off in 20 mb of ram. There are utilities that unload dlls to expediate the process.. (eg allocmem)

I couldn't get any Linux install floppy to boot and work on it, not even the ones that were advertised as working with 4MB core. I suppose this is due to IBM eating up 384 KB of memory (shadow ROM or something). Anyway, I made my own bootdisk with a 2.4.19 kernel with networking support, module for my NIC, and an uncompressed filesystem with busybox, fdisk, ip, mke2fs, insmod, mkswap and swapon, all statically linked to dietlibc. It worked great on my machine, allowed me to partition the hard drive, create and mount the swap partition, make and mount an ext2 file system, and install the files necessary for booting. I'm currently working on a uClibc-based system with picogui. It's almost finished and will be available from my website once it is.

    Hey, it wouldn't do much, but it's linux, it boots from a 386 without hard disk, and most of all it doesn't require a keyboard. Obviously, if you want a decent performance you need a P4 2.8 GHz.

    It took a lot of searching and a few false starts, but I finally got Linux going on my old laptop a few years ago. I guess I did it mostly for the challenge.

    Specs:

    386sx @ 16Mhz
    5 Megs RAM (subtract a bit for BIOS shadowing...)
    240MB HDD (half DOS, half Linux ext2)
    No PCMCIA, Ethernet, or IR ports.
    Currently boots MS-DOS/Win3.1 and then uses LoadLinux.
    Installed: Perl, GCC tool chain, vi, and just barely enough of everything else to get by.

    I tried FreeBSD first -- that's what I normally run on my Unix boxes. However, while it can run on 5MB, it is a real challenge to get it installed with only 5MB -- the installer needs 8MB, and with no swap partition set up, it can only use RAM.

    I came to the conclusion that the main problem with running a nice OS on not-so-nice hardware is getting a swap partition set up. Once Linux and FreeBSD have a little virtual memory to use, they can get by on just 4MB. But until the swap partition is mounted, everything has to squeeze into that 4MB, and it simply doesn't work.

    I tried a few other distros before I finally found something that worked. It was called "ZipHam Linux." It was a derivative of Slackware running 2.0.38, and specialized for HAM radio enthusiasts. Once I had a swap partition set up, I could actually do stuff. I transferred packages via MS-DOS's InterLnk (parallel cable) and upgraded to the latest kernel I thought would work.

    Recompiling the kernel on a 386sx with 4MB of RAM is an exercise in patience. I think it took about 23 hours. But it compiled! Yay. And booted.

    About a year later, I graduated from college, got a better job, and bought a more reasonable laptop. As a result, the old one doesn't see much use anymore. But I still think it is pretty cool. And since it is actually the only Linux box in the house (1 FreeBSD box, and I run Linux under Bochs occasionally, but no other hardware dedicated to Linux), I sometimes fire it up just for kicks.

    Many moons ago I made a 31/2" disk bootable to a stripped down version of Windows 3.1 with a stripped down WordPerfect 5.1, and it even included a HP LaserJet II driver. And I managed to leave solitaire on it too. I used to give them to guys who were going on travel before laptops became commonplace. There is usually a lot of bloat in any OS or software package.
