Linux Information Sheet
Michael K. Johnson,
v4.11, 13 January 1997

This document provides basic information about the Linux operating
system, including an explanation of Linux, a list of features, some
requirements, and some resources.

1. Introduction to Linux

Linux is a completely free reimplementation of the POSIX
specification, with SYSV and BSD extensions (which means it looks like
Unix, but does not come from the same source code base), which is
available in both source code and binary form. It is copyrighted by
Linus B. Torvalds (Linus.T...@Helsinki.FI) and other contributors,
and is freely redistributable under the terms of the GNU Public

Linux is not public domain, nor is it `shareware'. It is `free'
software, commonly called freeware, and you may give copies away, but
you must also give the source with it or make it available in the same
way. If you distribute any modifications, you are legally bound to
distribute the source for those modifications. See the GNU General
Public License for details. A copy is included with the Linux source,
or you can get a copy via ftp from in /pub/gnu/COPYING

Linux is still free as of version 2.0, and will continue to be.
Because of the nature of the GNU copyright which Linux is subject to,
it would be illegal for it to be made not free. Note carefully: it is
perfectly legal to charge money for distributing Linux, so long as you
also distribute the source code. This is a generalization; if you
want the fine points, read the GPL.

Linux runs on 386/486/Pentium machines with ISA, EISA, PCI and VLB
busses. MCA (IBM's proprietary bus) is not currently well-supported,
although support has been added to the current development tree,
2.1.x. If you are interested, see

There is a port in progress for multiple Motorola 680x0 platforms
(currently running on some Amigas, Ataris, and VME machines), which
now works quite well. It requires a 68020 with an MMU, a 68030,
68040, or a 68060, and also requires an FPU. Networking and X now

Linux runs well on DEC's Alpha CPU, currently supporting the "Jensen",
"NoName", "Cabriolet", "Universal Desktop Box" (better known as the
Multia), and many other platforms. For more information, see

Linux runs well on Sun SPARCs; most sun4c and sun4m machines now run
Linux, with support for sun4u in active development. Red Hat Linux is
(as of this writing) the only Linux distribution available for SPARCs;
see <>

Linux is being actively ported to the PowerPC architecture, including
PowerMac (Nubus and PCI), Motorola, IBM, and Be machines.

Ports to other machines, including MIPS and ARM, are under way and
showing various amounts of progress. Don't hold your breath, but if
you are interested and able to contribute, you may well find other
developers who wish to work with you.

Linux is no longer considered to be in beta testing, as version 1.0
was released on March 14, 1994. There are still bugs in the system,
and new bugs will creep up and be fixed as time goes on. Because
Linux follows the ``open development model'', all new versions will be
released to the public, whether or not they are considered
``production quality''. However, in order to help people tell whether
they are getting a stable version or not, the following scheme has
been implemented: Versions 1.x.y, where x is an even number, are
stable versions, and only bug fixes will be applied as y is
incremented. So from version 1.2.2 to 1.2.3, there were only bug
fixes, and no new features. Versions 1.x.y, where x is an odd number,
are beta-quality releases for developers only, and may be unstable and
may crash, and are having new features added to them all the time.
>From time to time, as the currect development kernel stabilizes, it
will be frozen as the new ``stable'' kernel, and development will
continue on a new development version of the kernel.

The current stable version is 2.0.27 (this will continue to change as
new device drivers get added and bugs fixed), and developement has
also started on the experimental 2.1.x kernels. If 2.0.x is too new
for you, you may want to stick with 1.2.13 for the time being.
However, the latest releases of 2.0 have proved quite stable. Do note
that in order to upgrade from 1.2 to 2.0, you need to upgrade some
utilities as well; you may wish to upgrade to the latest version of
your Linux distribution in order to obtain those utilities. The Linux
kernel source code also contains a file, Documentation/Changes, which
explains these changes and more.

Most versions of Linux, beta or not, are quite stable, and you can
keep using those if they do what you need and you don't want to be on
the bleeding edge. One site had a computer running version 0.97p1
(dating from the summer of 1992) for over 136 days without an error or
crash. (It would have been longer if the backhoe operator hadn't
mistaken a main power transformer for a dumpster...) Others have
posted uptimes in excess of a year. One site still had a computer
running Linux 0.99p15s over 600 days at last report.

One thing to be aware of is that Linux is developed using an open and
distributed model, instead of a closed and centralized model like much
other software. This means that the current development version is
always public (with up to a week or two of delay) so that anybody can
use it. The result is that whenever a version with new functionality
is released, it almost always contains bugs, but it also results in a
very rapid development so that the bugs are found and corrected
quickly, often in hours, as many people work to fix them.

In contrast, the closed and centralized model means that there is only
one person or team working on the project, and they only release
software that they think is working well. Often this leads to long
intervals between releases, long waiting for bug fixes, and slower
development. Of course, the latest release of such software to the
public is often of higher quality, but the development speed is
generally much slower.

As of January 13, 1997, the current stable version of Linux is 2.0.27,
and the latest development version is 2.1.20.

2. Linux Features

· multitasking: several programs running at once.

· multiuser: several users on the same machine at once (and no two-
user licenses!).

· multiplatform: runs on many different CPUs, not just Intel.

· multiprocessor: SMP support is available on the Intel and SPARC
platforms (with work currently in progress on other platforms), and
Linux is used in several loosely-coupled MP applications, including
Beowulf systems (see <
web/beowulf/beowulf.html>) and the Fujitsu AP1000+ SPARC-based

· runs in protected mode on the 386.

· has memory protection between processes, so that one program can't
bring the whole system down.

· demand loads executables: Linux only reads from disk those parts of
a program that are actually used.

· shared copy-on-write pages among executables. This means that
multiple process can use the same memory to run in. When one tries
to write to that memory, that page (4KB piece of memory) is copied
somewhere else. Copy-on-write has two benefits: increasing speed
and decreasing memory use.

· virtual memory using paging (not swapping whole processes) to disk:
to a separate partition or a file in the filesystem, or both, with
the possibility of adding more swapping areas during runtime (yes,
they're still called swapping areas). A total of 16 of these 128
MB swapping areas can be used at once, for a theoretical total of 2
GB of useable swap space. It is simple to increase this if
necessary, by changing a few lines of source code.

· a unified memory pool for user programs and disk cache, so that all
free memory can be used for caching, and the cache can be reduced
when running large programs.

· dynamically linked shared libraries (DLL's), and static libraries
too, of course.

· does core dumps for post-mortem analysis, allowing the use of a
debugger on a program not only while it is running but also after
it has crashed.

· mostly compatible with POSIX, System V, and BSD at the source

· through an iBCS2-compliant emulation module, mostly compatible with
SCO, SVR3, and SVR4 at the binary level.

· all source code is available, including the whole kernel and all
drivers, the development tools and all user programs; also, all of
it is freely distributable. Plenty of commercial programs are
being provided for Linux without source, but everything that has
been free, including the entire base operating system, is still

· POSIX job control.

· pseudoterminals (pty's).

· 387-emulation in the kernel so that programs don't need to do their
own math emulation. Every computer running Linux appears to have a
math coprocessor. Of course, if your computer already contains an
FPU, it will be used instead of the emulation, and you can even
compile your own kernel with math emulation removed, for a small
memory gain.

· support for many national or customized keyboards, and it is fairly
easy to add new ones dynamically.
· multiple virtual consoles: several independent login sessions
through the console, you switch by pressing a hot-key combination
(not dependent on video hardware). These are dynamically
allocated; you can use up to 64.

· Supports several common filesystems, including minix, Xenix, and
all the common system V filesystems, and has an advanced filesystem
of its own, which offers filesystems of up to 4 TB, and names up to
255 characters long.

· transparent access to MS-DOS partitions (or OS/2 FAT partitions)
via a special filesystem: you don't need any special commands to
use the MS-DOS partition, it looks just like a normal Unix
filesystem (except for funny restrictions on filenames,
permissions, and so on). MS-DOS 6 compressed partitions do not
work at this time without a patch (dmsdosfs). VFAT (WNT, Windows
95) support is available in Linux 2.0

· special filesystem called UMSDOS which allows Linux to be installed
on a DOS filesystem.

· read-only HPFS-2 support for OS/2 2.1

· HFS (Macintosh) file system support is available separately as a

· CD-ROM filesystem which reads all standard formats of CD-ROMs.

· TCP/IP networking, including ftp, telnet, NFS, etc.

· Appletalk server

· Netware client and server

· Lan Manager (SMB) client and server

· Many networking protocols: the base protocols available in the
latest development kernels include TCP, IPv4, IPv6, AX.25, X.25,
IPX, DDP (Appletalk), NetBEUI, Netrom, and others. Stable network
protocols included in the stable kernels currently include TCP,
IPv4, IPX, DDP, and AX.25.

3. Hardware Issues

3.1. Minimal configuration

The following is probably the smallest possible configuration that
Linux will work on: 386SX/16, 1 MB RAM, 1.44 MB or 1.2 MB floppy, any
supported video card (+ keyboards, monitors, and so on of course).
This should allow you to boot and test whether it works at all on the
machine, but you won't be able to do anything useful. See
<> for minimal Linux

In order to do something, you will want some hard disk space as well,
5 to 10 MB should suffice for a very minimal setup (with only the most
important commands and perhaps one or two small applications
installed, like, say, a terminal program). This is still very, very
limited, and very uncomfortable, as it doesn't leave enough room to do
just about anything, unless your applications are quite limited. It's
generally not recommended for anything but testing if things work, and
of course to be able to brag about small resource requirements.

3.2. Usable configuration

If you are going to run computationally intensive programs, such as
gcc, X, and TeX, you will probably want a faster processor than a
386SX/16, but even that should suffice if you are patient.

In practice, you will want at least 4 MB of RAM if you don't use X,
and 8 MB if you do. Also, if you want to have several users at a
time, or run several large programs (compilations for example) at a
time, you may want more than 4 MB of memory. It will still work with
a smaller amount of memory (should work even with 2 MB), but it will
use virtual memory (using the hard drive as slow memory) and that will
be so slow as to be unusable. If you use many programs at once, 16 MB
will reduce swapping considerably. If you don't want to swap
appreciably under any normal load, 32 MB will probably suffice. Of
course, if you run memory-hungry applications, you may want more.

The amount of hard disk you need depends on what software you want to
install. The normal basic set of Unix utilities, shells, and
administrative programs should be comfortable in less than 10 MB, with
a bit of room to spare for user files. For a more complete system,
get Red Hat, Debian, Slackware, or another distribution, and assume
that you will need 60 to 300 MB, depending on what you choose to
install and what distribution you get. Add whatever space you want to
reserve for user files to these totals. With today's prices on hard
drives, if you are buying a new system, it makes no sense to buy a
drive that is too small. Get at least 500 MB, preferably 1GB or more,
and you will not regret it.

Add more memory, more hard disk, a faster processor and other stuff
depending on your needs, wishes and budget to go beyond the merely
usable. In general, one big difference from DOS is that with Linux,
adding memory makes a large difference, whereas with DOS, extra memory
doesn't make that much difference. This of course has something to do
with DOS's 640KB limit, which is completely nonexistent under Linux.

3.3. Supported hardware

Anything that runs 386 protected mode programs (all models of
386's 486's, 586's, and 686's should work. 286s and below may
someday be supported on a smaller kernel called ELKS (Embeddable
Linux Kernel Subset), but don't expect the same capabilities. A
version for the 680x0 CPU (for x = 2 with external MMU, 3, 4,
and 6) which runs on Amigas and Ataris can be found at in the 680x0 directory. Many DEC Alphas are
supported. Many SPARCs are now supported. Ports are also being
done to the PowerPC, ARM, and MIPS architectures. More details
are available elsewhere.

ISA or EISA bus. MCA (mostly true blue PS/2's) support is
incomplete but improving (see above). Local busses (VLB and
PCI) work. Linux puts higher demands on hardware than DOS,
Windows, and in fact most operating systems. This means that
some marginal hardware that doesn't fail when running less
demanding operating system may fail when running Linux. Linux
is an excellent memory tester...

Up to 1 GB on Intel; more on 64-bit platforms. Some people
(including Linus) have noted that adding ram without adding more
cache at the same time has slowed down their machine extremely,
so if you add memory and find your machine slower, try adding
more cache. Some machines can only cache certain amounts of
memory regardless of how much RAM is installed (64 MB is the
most one popular chipset can cache). Over 64 MB of memory will
require a boot-time parameter, as the BIOS cannot report more
than 64MB, because it is ``broken as designed.''

Data storage:
Generic AT drives (EIDE, IDE, 16 bit HD controllers with MFM or
RLL, or ESDI) are supported, as are SCSI hard disks and CD-ROMs,
with a supported SCSI adaptor. Generic XT controllers (8 bit
controllers with MFM or RLL) are also supported. Supported SCSI
adaptors: Advansys, Adaptec 1542, 1522, 1740, 27xx, and 29xx
(with some exceptions) series, Buslogic MultiMaster controllers
(Flashpoint support is in beta-testing), NCR53c810-based
controllers, DPT controllers, Qlogic ISP and FAS controllers,
Seagate ST-01 and ST-02, Future Domain TMC-88x series (or any
board based on the TMC950 chip) and TMC1660/1680, Ultrastor 14F,
24F and 34F, Western Digital wd7000, and others. SCSI, QIC-02,
and some QIC-80 tapes are also supported. Several CD-ROM devices
are also supported, including Matsushita/Panasonic, Mitsumi,
Sony, Soundblaster, Toshiba, ATAPI (EIDE), SCSI, and others.
For exact models, check the hardware compatibility HOWTO.

VGA, EGA, CGA, or Hercules (and compatibles) work in text mode.
For graphics and X, there is support for (at least) normal VGA,
some super-VGA cards (most of the cards based on ET3000, ET4000,
Paradise, and some Trident chipsets), S3, 8514/A, ATI
MACH8/32/64, and hercules. (Linux uses the Xfree86 X server, so
that determines what cards are supported. A full list of
supported chipsets alone takes over a page.)

Ethernet support includes 3COM 503/509/579/589 (501/505/507 are
supported but not recomended), AT&T GIS (neé NCR) WaveLAN, most
WD8390-based cards, most WD80x3-based cards, NE1000/2000 and
most clones, AC3200, Apricot 82596, AT1700, ATP,
DE425/434/435/500, D-Link DE-600/620, DEPCA, DE100/101,
DE200/201/202 Turbo, DE210, DE422, Cabletron E2100 (not
recommended), Intel EtherExpress (not recommended), DEC
EtherWORKS 3, HP LAN, HP PCLAN/plus, most AMD LANCE-based cards,
NI5210, ni6510, SMC Ultra, DEC 21040 (tulip), Zenith Z-Note
ethernet, All Zircom cards and all Cabletron cards other than
the E2100 are unsupported, due to the manufacturers
unwillingness to release programming information freely.

FDDI support currently includes the DEFxx cards from DEC.

Point-to-Point networking support include PPP, SLIP, CSLIP, and

Most 16450 and 16550 UART-based boards, including AST Fourport,
the Usenet Serial Card II, and others. Intelligent boards
supported include Cyclades Cyclom series (supported by the
manufacturer), Comtrol Rocketport series (supported by the
manufacturer), Stallion (most boards; supported by the
manufacturer), and Digi (some boards; not manufacturer-
supported). Some ISDN, frame relay, and leased line hardware is
Other hardware:
SoundBlaster, ProAudio Spectrum 16, Gravis Ultrasound, most
other sound cards, most (all?) flavours of bus mice (Microsoft,
Logitech, PS/2), etc.

4. An Incomplete List of Ported Programs and Other Software

Most of the common Unix tools and programs have been ported to Linux,
including almost all of the GNU stuff and many X clients from various
sources. Actually, ported is often too strong a word, since many
programs compile out of the box without modifications, or only small
modifications, because Linux tracks POSIX quite closely.
Unfortunately, there are not as many end-user applications yet as we
would like, but this is changing rapidly. Contact the vendor of your
favorite commercial Unix application and ask if they have ported it to

Here is an incomplete list of software that is known to work under

Basic Unix commands:
ls, tr, sed, awk and so on (you name it, Linux probably has it).

Development tools:
gcc, gdb, make, bison, flex, perl, rcs, cvs, prof.

Languages and Environments:
C, C++, Objective C, Java, Modula-3, Modula-2, Oberon, Ada95,
Pascal, Fortran, ML, scheme, Tcl/tk, Perl, Python, Common Lisp,
and many others.

Graphical environments:
X11R5 (XFree86 2.x), X11R6 (XFree86 3.x), MGR.

GNU Emacs, XEmacs, MicroEmacs, jove, ez, epoch, elvis (GNU vi),
vim, vile, joe, pico, jed, and others.

bash (POSIX sh-compatible), zsh (includes ksh compatiblity
mode), pdksh, tcsh, csh, rc, es, ash (mostly sh-compatible shell
used as /bin/sh by BSD), and many more.

Taylor (BNU-compatible) UUCP, SLIP, CSLIP, PPP, kermit, szrz,
minicom, pcomm, xcomm, term (runs multiple shells, redirects
network activity, and allows remote X, all over one modem line),
Seyon (popular X-windows communications program), and several
fax and voice-mail (using ZyXEL and other modems) packages are
available. Of course, remote serial logins are supported.

News and mail:
C-news, innd, trn, nn, tin, smail, elm, mh, pine, etc.

TeX, groff, doc, ez, LyX, Lout, Linuxdoc-SGML, and others.
Nethack, several Muds and X games, and lots of others. One of
those games is looking through all the games available at tsx-11
and sunsite.

AUIS, the Andrew User Interface System. ez is part of this

All of these programs (and this isn't even a hundredth of what is
available) are freely available. Commercial software is becoming
widely available; ask the vendor of your favorite commercial software
if they support Linux.

5. Who uses Linux?

Linux is freely available, and no one is required to register their
copies with any central authority, so it is difficult to know how many
people use Linux. Several businesses are now surviving solely on
selling and supporting Linux, and very few Linux users use those
businesses, relatively speaking, and the Linux newsgroups are some of
the most heavily read on the internet, so the number is likely in the
hundreds of thousands, but hard numbers are hard to come by. However,
one brave soul, Harald T. Alvestrand, has decided to try, and asks
that if you use Linux, you send a message to
with one of the following subjects: ``I use Linux at home'', ``I use
Linux at work'', or ``I use Linux at home and at work''. He is also
counting votes of ``I don't use Linux'', for some reason. He posts
his counts to comp.os.linux.misc.

6. Getting Linux

6.1. Anonymous FTP

Matt Welsh has released a new version of his Installation and Getting
Started guide, version 2.1.1. Also, the Linux Documentation Project
(the LDP) has put out several other books in various states of
completion, and these are available at Stay tuned to
comp.os.linux.announce. The Linux Documentation Project home page is
at <>

At least the following anonymous ftp sites carry Linux.

Textual name Numeric address Linux directory
============================= =============== =============== /pub/linux /pub/Linux /pub/OS/Linux /pub/linux /pub/linux /packages/linux /pub/linux /pub/comp/os/linux /pub/linux /pub/Linux /pub/os/Linux /pub/linux /systems/unix/linux mirrors/linux /pub/linux /pub/linux /pub/os/linux /pub/Linux /pub/OS/linux /Operating-Systems/Linux /mirror/linux /pub/Linux /pub/linux /pub/linux /pub/linux and are the official sites
for Linux' GCC. Some sites mirror other sites. Please use the site
closest (network-wise) to you whenever possible.

At least and offer
ftpmail services. Mail or f...@informatik.tu- for help.

If you are lost, try looking at, where several distributions
are offered. Red Hat Linux, Debian, and Slackware appear to be the
most popular distributions at the moment.

6.2. CDROM

Most people now install Linux from CDROM's. The distributions have
grown to hundreds of MBs of Linux software, and downloading that over
even a 28.8 modem takes a long time.

There are essentially two ways to purchase a Linux distribution on
CDROM: as part of an archive of FTP sites, or directly from the
manufacturer. If you purchase an archive, you will almost always get
several different distributions to choose from, but usually support is
not included. When you purchase a distribution directly from the
vendor, you usually only get one distribution, but you usually get
some form of support, usually installation support.

6.3. Other methods of obtaining Linux

There are many BBS's that have Linux files. A list of them is
occasionally posted to comp.os.linux.announce. Ask friends and user
groups, or order one of the commmercial distributions. A list of
these is contained in the Linux distribution HOWTO, available as, and posted
regularily to the comp.os.linux.announce newsgroup.

7. Getting started

As mentioned at the beginning, Linux is not centrally administered.
Because of this, there is no ``official'' release that one could point
at, and say ``That's Linux.'' Instead, there are various
``distributions,'' which are more or less complete collections of
software configured and packaged so that they can be used to install a
Linux system.

The first thing you should do is to get and read the list of
Frequently Asked Questions (FAQ) from one of the FTP sites, or by
using the normal Usenet FAQ archives (e.g. This
document has plenty of instructions on what to do to get started, what
files you need, and how to solve most of the common problems (during
installation or otherwise).

8. Legal Status of Linux

Although Linux is supplied with the complete source code, it is
copyrighted software, not public domain. However, it is available for
free under the GNU General Public License, sometimes referred to as
the ``copyleft''. See the GPL for more information. The programs
that run under Linux each have their own copyright, although many of
them use the GPL as well. X uses the MIT X copyright, and some
utilities are under the BSD copyright. In any case, all of the
software on the FTP site is freely distributable (or else it shouldn't
be there).

9. News About Linux

A monthly magazine, called Linux Journal, was launched over two years
ago. It includes articles intended for almost all skill levels, and
is intended to be helpful to all Linux users. One-year subscriptions
are $22 in the U.S., $27 in Canada and Mexico, and $32 elsewhere,
payable in US currency. Subscription inquiries can be sent via email
to, or faxed to +1-206-782-7191, or phoned to
+1-206-782-7733, or mailed to Linux Journal, PO Box 85867, Seattle, WA
98145-1867 USA. SSC has a PGP public key available for encrypting
your mail to protect your credit card number; finger to
get the key.

There are several Usenet newsgroups for Linux discussion, and also
several mailing lists. See the Linux FAQ for more information about
the mailing lists (you should be able to find the FAQ either in the
newsgroup or on the FTP sites).

The newsgroup comp.os.linux.announce is a moderated newsgroup for
announcements about Linux (new programs, bug fixes, etc).

The newsgroup comp.os.linux.answers is a moderated newsgroup to which
the Linux FAQ, HOWTO documents, and other documentation postings are

The newsgroup comp.os.linux.admin is an unmoderated newsgroup for
discussion of administration of Linux systems.

The newsgroup comp.os.linux.development.system is an unmoderated
newsgroup specifically for discussion of Linux kernel development.
The only application development questions that should be discussed
here are those that are intimately associated with the kernel. All
other development questions are probably generic Unix development
questions and should be directed to a comp.unix group instead, unless
they are very Linux-specific applications questions, in which case
they should be directed at comp.os.linux.development.apps.

The newsgroup comp.os.linux.development.apps is an unmoderated
newsgroup specifically for discussion of Linux-related applications
development. It is not for discussion of where to get applications
for Linux, nor a discussion forum for those who would like to see
applications for Linux.

The newsgroup comp.os.linux.hardware is for Linux-specific hardware

The newsgroup comp.os.linux.networking is for Linux-specific
networking development and setup questions.

The newsgroup comp.os.linux.x is for Linux-specific X Windows

The newsgroup comp.os.linux.misc is the replacement for comp.os.linux,
and is meant for any discussion that doesn't belong elsewhere.

In general, do not crosspost between the Linux newsgroups. The only
crossposting that is appropriate is an occasional posting between one
unmoderated group and comp.os.linux.announce. The whole point of
splitting comp.os.linux into many groups is to reduce traffic in each.
Those that do not follow this rule will be flamed without mercy...

10. The Future

After Linux 1.0 was released, work was done on several enhancements.
Linux 1.2 included disk access speedups, TTY improvements, virtual
memory enhancements, multiple platform support, quotas, and more.
Linux 2.0, the current stable version, has even more enhancements,
including many performance improvements, several new networking
protocols, one of the fastest TCP/IP implementations in the world, and
far, far more. Even higher performance, more networking protocols,
and more device drivers will be available in Linux 2.2.

Even with over 3/4 million lines of code in the kernel, there is
plenty of code left to write, and even more documentation. Please
join the mailing list if you would like to
contribute to the documentation. Send mail to with a single line containing the word
``help'' in the body (NOT the subject) of the message.
