3.4. What News Groups Are There for Linux?

Comp.os.linux.announce is the moderated announcements group; you
should read this if you intend to use Linux: it contains information
about software updates, new ports, user group meetings, and
commercial products. It is the ONLY newsgroup that may carry
commercial postings. Submissions for that group should be e-mailed to
mailto:[EMAIL PROTECTED].

Comp.os.linux.announce, however, is not archived on DejaNews or Alta
Vista. The only archive for the news group seems to be http://
www.iki.fi/mjr/linux/cola.html.

[Axel Boldt]

Also worth reading are the following other groups in the
comp.os.linux.* hierarchy--you may find many common problems too
recent for the documentation but are answered in the newsgroups.

  * alt.uu.comp.os.linux
   
  * alt.uu.comp.os.linux.questions
   
  * comp.os.linux.admin
   
  * comp.os.linux.advocacy
   
  * comp.os.linux.alpha
   
  * comp.os.linux.answers
   
  * comp.os.linux.development
   
  * comp.os.linux.development.apps
   
  * comp.os.linux.development.system
   
  * comp.os.linux.embedded
   
  * comp.os.linux.hardware
   
  * comp.os.linux.help
   
  * comp.os.linux.m68k
   
  * comp.os.linux.misc
   
  * comp.os.linux.network
   
  * comp.os.linux.networking
   
  * comp.os.linux.portable
   
  * comp.os.linux.powerpc
   
  * comp.os.linux.questions
   
  * comp.os.linux.redhat
   
  * comp.os.linux.security
   
  * comp.os.linux.setup
   
  * comp.os.linux.test
   
  * comp.os.linux.x
   
  * comp.os.linux.x.video
   

Remember that Linux is POSIX compatible, and most all of the material
in comp.unix.* and comp.windows.x.* groups will be relevant. Apart
from hardware considerations, and some obscure or very technical
low-level issues, you'll find that these groups are good places to
start.

Please read ("You Still Haven't Answered My Question!") before
posting. Cross posting between different comp.os.linux.* groups is
rarely a good idea.

There may well be Linux groups local to your institution or
area--check there first.

See also ("I Don't Have Usenet Access. Where Do I Get Information?")

Other regional and local newsgroups also exist--you may find the
traffic more manageable there. The French Linux newsgroup is
fr.comp.os.linux. The German one is de.comp.os.linux. In Australia,
try aus.computers.linux. In Croatia there is hr.comp.linux. In Italy,
there is it.comp.linux.
=====================================================================

3.5. What Other FAQ's Are There for Linux?

There are a number of special-interest FAQ's on different subjects
that are related to Linux administration and use. Here are a few of
them:

  * A FAQ for new users. http://homes.arealcity.com/swietanowski/
    LinuxFAQ/.
   
  * BASH Frequently Asked Questions ftp://ftp.cwru.edu/pug/bash/FAQ/.
   
  * Frequently Asked Questions about Open Source. http://
    www.opensource.org/faq.html.
   
  * GNU Emacs. http://www.lerner.co.il/emacs/faq-body.shtml.
   
  * GNU Linux in Science and Engineering. http://members.home.net/
    scieng/.
   
  * Gnus 5.x. http://www.ccs.neu.edu/software/contrib/gnus/.
   
  * List of Periodic Information Postings ftp://rtfm.mit.edu/pub/
    usenet/news.answers/periodic-postings/.
   
  * Sendmail. http://www.sendmail.org/faq/.
   

=====================================================================
3.6. Where Can I Get Linux Material by FTP?

There are three main archive sites for Linux:

  * ftp://ftp.funet.fi/pub/OS/Linux/ (Finland).
   
  * ftp://metalab.unc.edu/pub/Linux/ (US).
   
  * tsx-11.mit.edu//pub/linux/ (US).
   

The best place to get the Linux kernel is ftp://ftp.kernel.org/pub/
linux/kernel/. Linus Torvalds uploads the most recent kernel versions
to this site.

Of the U.S. distributions, Debian GNU/Linux is available at ftp://
ftp.debian.org/pub/debian/. Red Hat Linux's home site is ftp://
ftp.redhat.com/, and Linux Slackware's is ftp://ftp.freesoftware.com/
. 

The Small Linux distribution, which can run in 2 MB of RAM, is
located at http://smalllinux.netpedia.net/.

The contents of these sites is mirrored (copied, usually
approximately daily) by a number of other sites. Please use a site
close to you--it will be faster for you and easier on the network.

Please send updates and corrections to this list to the Linux FAQ
maintainer, mailto:[EMAIL PROTECTED] Not all of these mirror
all of the other "source" sites, and some have material not available
on the "source" sites.
=====================================================================

3.7. I Don't Have FTP Access. Where Do I Get Linux?

The easiest thing is probably to find a friend with FTP access. If
there is a Linux user's group near you, they may be able to help.

If you have a reasonably good email connection, you could try the
FTP-by-mail servers at mailto:[EMAIL PROTECTED], or mailto:
[EMAIL PROTECTED]

Linux is also available via traditional mail on CD-ROM. The file ftp:
//metalab.unc.edu/pub/Linux/docs/HOWTO/Installation-HOWTO, and the
file ftp://metalab.unc.edu/pub/Linux/docs/HOWTO/Distribution-HOWTO
contain information on these distributions.
=====================================================================

3.8. I Don't Have Usenet Access. Where Do I Get Information?

A digest of comp.os.linux.announce is available by mailing the word
"subscribe" (without the quotes) as the body of a message to mailto:
[EMAIL PROTECTED] Subscribing to this list
is a good idea, as it carries important information and documentation
about Linux.

Please remember to use the *-request addresses for your subscribe and
unsubscribe messages; mail to the other address is posted to the news
group.
=====================================================================

3.9. What Mailing Lists Are There?

The Linux developers now mainly use the Majordomo server at mailto:
[EMAIL PROTECTED] Send a message with the word "lists"
(without the quotes) in the body to get a list of lists there. Add a
line with the word, "help," to get the standard Majordomo help file
that lists instructions for subscribing and unsubscribing to the
lists.

Please do not post off-topic material to the mailing lists. Most of
them are used by Linux developers to talk about technical issues and
future developments. They are not intended for new users' questions,
advertisements, or public postings that are not directly related to
the mailing list's subject matter. Comp.os.linux.announce is the
place for all public announcements. This is a common Internet policy.
If you don't observe this guideline, there's a good chance that
you'll be flamed.

There is a linux-newbie list where, "no question is too stupid."
Unfortunately, it seems that few experienced users read that list,
and it has very low volume.

There are numerous Linux related mailing lists at http://
www.onelist.com/. Go to the categories page and choose "Linux."
=====================================================================

3.10. Where Are Linux Legal Issues Discussed?

On the linux-legal mailing list, of course. You can subscribe to it,
as with many of the other Linux related lists, by sending a message
with the word "help" in the body of the message to mailto:
[EMAIL PROTECTED]
=====================================================================

3.11. Are the News Groups Archived Anywhere?

The Usenet Linux news groups are archived at http://www.dejanews.com/
, and http://altavista.digital.com/.

http://www.reference.com/ is unavailable until further notice,
apparently due to lack of support.

ftp://metalab.unc.edu/pub/Linux/docs/linux-announce.archive contains
archives of comp.os.linux.announce. These are mirrored from 
src.doc.ic.ac.uk/usenet/, which also archives comp.os.linux,
comp.os.linux.development.apps, and comp.os.linux.development.system.

There is an `easy to access' archive of comp.os.linux.announce on the
World Wide Web at http://www.leo.org/archiv/unix/linux/ which
supports searching and browsing.
=====================================================================

3.12. Where Can I Find Out About Security Related Issues?

Look at http://www.rootshell.com/, which has information about
security problems and software.
=====================================================================

4. Compatibility with Other Operating Systems

4.1. Can Linux Share My Disk with DOS? OS/2? 386BSD? Win95?

Yes. Linux uses the standard MS-DOS partitioning scheme, so it can
share your disk with other operating systems. Note, however, that
many other operating systems may not be exactly compatible. DOS's
FDISK.EXE and FORMAT.EXE, for example, can overwrite data in a Linux
partition, because they sometimes incorrectly use partition data from
the partition's boot sector rather than the partition table.

In order to prevent programs from doing this, it is a good idea to
zero out--under Linux--the start of a partition you created, before
you use MS-DOS--or whatever--to format it. Type:

$ dd if=/dev/zero of=/dev/hdXY bs=512 count=1                        

where hdXY is the relevant partition; e.g., /dev/hda1 for the first
partition of the first (IDE) disk.

Linux can read and write the files on your DOS and OS/2 FAT
partitions and floppies using either the DOS file system type built
into the kernel or mtools. There is kernel support for the VFAT file
system used by Windows 9x and Windows NT.

There is reportedly a GPL'd OS/2 device driver that will read and
write Linux ext2 partitions.

For information about FAT32 partition support, see http://
bmrc.berkeley.edu/people/chaffee/fat32.html.

See, ("What Software Does Linux Support?") for details and status of
the emulators for DOS, MS Windows, and System V programs.

See also, "Can Linux access Amiga file systems? ", "Can Linux access
Macintosh file systems? ", "Can Linux access BSD, SysV, etc., UFS? ",
and "Can Linux access SMB file systems? "

There are said to be NTFS drivers under development, which should
support compression as a standard feature.
=====================================================================

4.2. How Do I Access Files on My DOS Partition Or Floppy?

Use the DOS file system, type, for example:

$ mkdir /dos                                                          
$ mount -t msdos -o conv=text,umask=022,uid=100,gid=100 /dev/hda3 /dos

If it's a floppy, don't forget to umount it before ejecting it!

You can use the conv=text/binary/auto, umask=nnn, uid=nnn, and gid=
nnn options to control the automatic line-ending conversion,
permissions and ownerships of the files in the DOS file system as
they appear under Linux. If you mount your DOS file system by putting
it in your /etc/fstab, you can record the options (comma-separated)
there, instead of defaults.

Alternatively, you can use mtools, available in both binary and
source form on the FTP sites. ("Where Can I Get Linux Material by
FTP?")

A kernel patch (known as the fd-patches) is available which allows
floppies with nonstandard numbers of tracks and/or sectors to be
used; this patch is included in the 1.1 alpha testing kernel series.
=====================================================================

4.3. Does Linux Support Compressed Ext2 file Systems?

The ext2compr project provides a kernel patch Information about them
is located at http://e2ompr.memalpha.cx/e2compr/.

There is also a Web site for the e2compr patches. The code is still
experimental and consists of patches for the 2.0 and 2.1 kernels. For
more information about the project, including the latest patches, and
the address of the mailing list, look up the URL at http://
debs.fuller.edu/e2compr/.

[Roderich Schupp, Peter Moulder]

zlibc is a program that allows existing applications to read
compressed (GNU gzip'ed) files as if they were not compressed. Look
at ftp://metalab.unc.edu/pub/Linux/libs/. The author is Alain Knaff.

There is also a compressing block device driver, "DouBle," by
Jean-Marc Verbavatz, which can provide on-the-fly disk compression in
the kernel. The source-only distribution is located at ftp://
metalab.unc.edu/pub/Linux/patches/diskdrives/. This driver compresses
inodes and directory information as well as files, so any corruption
of the file system is likely to be serious.

There is also a package called tcx (Transparently Compressed
Executables), which allows you to keep infrequently compressed
executables compressed and only uncompress them temporarily when in
use. It is located at ftp://metalab.unc.edu/pub/Linux/utils/compress/
. 
=====================================================================

4.4. Can I Use My Stacked/DBLSPC/Etc. DOS Drive?

Until recently, not very easily. You can access DOS 6.X volumes from
the DOS emulator ("What software does Linux support? "), but it's
harder than accessing a normal DOS volume via the DOS kernel option,
a module, or mtools.

There is a recently added package, dmsdos, that reads and writes
compressed file systems like DoubleSpace/DriveSpace in MS-DOS 6.x and
Win95, as well as Stacker versions 3 and 4. It is a loadable kernel
module. Look at ftp://metalab.unc.edu/pub/Linux/system/filesystems/
dosfs/.
=====================================================================

4.5. Can I Access OS/2 HPFS Partitions from Linux?

Yes, but Linux access to HPFS partitions is read-only. HPFS file
system access is available as an option when compiling the kernel or
as a module. See the Documentation/filesystems/hpfs.txt file in the
kernel source distribution. ("How Do I Upgrade/Recompile My Kernel?")
Then you can mount HPFS partition, using, for example:

$ mkdir /hpfs                                                        
$ mount -t hpfs /dev/hda5 /hpfs                                      
=====================================================================

4.6. Can Linux Access Amiga File Systems?

The Linux kernel has support for the Amiga Fast File System (AFFS)
version 1.3 and later, both as a compile-time option and as a module.
The file Documentation/filesystems/affs.txt in the Linux kernel
source distribution has more information.

See ("How Do I Upgrade/Recompile My Kernel?")

Linux supports AFFS hard-drive partitions only. Floppy access is not
supported due to incompatibilities between Amiga floppy controllers
and PC and workstation controllers. The AFFS driver can also mount
disk partitions used by the Un*x Amiga Emulator, by Bernd Schmidt.
=====================================================================

4.7. Can Linux Access BSD, SysV, Etc. UFS?

Recent kernels can mount (read only) the UFS file system used by
System V; Coherent; Xenix; BSD; and derivatives like SunOS, FreeBSD,
NetBSD, and NeXTStep. UFS support is available as a kernel
compile-time option and a module.

See, ("How Do I Upgrade/Recompile My Kernel?")
=====================================================================

4.8. Can Linux Access SMB File Systems?

Linux supports read/write access of Windows for Workgroups and
Windows NT SMB volumes. See the file Documentation/filesystems/
smbfs.txt of the Linux kernel source distribution, and ("How Do I
Upgrade/Recompile My Kernel?")

There is also a suite of programs called Samba which provide support
for WfW networked file systems (provided they're for TCP/IP).
Information is available in the README file at metalab.unc.edu/pub/
Linux/system/network/samba/.

The SMB Web site is http://www.samba.org/, and there is also a Web
site at samba.anu.edu.au/samba/.
=====================================================================

4.9. Can Linux Access Macintosh File Systems?

There is a set of user-level programs that read and write the older
Macintosh Hierarchical File System (HFS). It is available at 
metalab.unc.edu/pub/Linux/utils/disk-management/.

Access to the newer, HFS+ file systems is still under development.
=====================================================================

4.10. Can I Run Microsoft Windows Programs under Linux?

WINE, a MS Windows emulator for Linux, is still not ready for general
distribution. If you want to contribute to its development, look for
the status reports in the comp.emulators.ms-windows.wine newsgroup.

There is also a FAQ, compiled by P. David Gardner, at ftp://
metalab.unc.edu/pub/Linux/docs/faqs/Wine-FAQ/.

In the meantime, if you need to run MS Windows programs, the best
bet--seriously--is to reboot. LILO, the Linux boot loader, can boot
one of several operating systems from a menu. See the LILO
documentation for details.

Also, LOADLIN.EXE (a DOS program to load a Linux, or other OS, kernel
is one way to make Linux co-exist with DOS. LOADLIN.EXE is
particularly handy when you want to install Linux on a 3rd or 4th
drive on a system (or when you're adding a SCSI drive to a system
with an existing IDE).

In these cases, it is common for LILO's boot loader to be unable to
find or load the kernel on the "other" drive. So you just create a C:
\LINUX directory (or whatever), put LOADLIN.EXE in it with a copy of
your kernel, and use that.

LOADLIN.EXE is a VCPI compliant program. Win95 will want to,
"shutdown into DOS mode," to run it (as it would with certain other
DOS protected-mode programs).

Earlier versions of LOADLIN.EXE sometimes required a package called
REALBIOS.COM, which required a boot procedure on an (almost) blank
floppy to map the interrupt vectors (prior to the loading of any
software drivers). (Current versions don't seem to ship with it, and
don't seem to need it).

[Jim Dennis]
=====================================================================

4.11. Where Can I Get Information about NFS Compatibility?

This information is partly taken from Nicolai Langfeldt's excellent
NFS HOWTO, and is current as of 10/1/1999.

Most version 2.2.x kernels need a set of patches to install the knfsd
subsystem, maintained by H.J. Lu, to communicate efficiently (if at
all) with Sparc, IBM RS, and Alpha machines, and probably others.
This package is actually a collection of patches to the kernel
sources.

There is also a user-space server. Although it lacks remote file
locking, it is easier to install. It may be equally efficient.

In the Documentation/Changes of recent kernel distributions, there is
a list of URL's for both the knfsd server and the user-space server.

There is a CVS server available for the kernel-space NFS subsystem,
as well as a NFS WWW page at http://www.linuxnfs.sourceforge.org/,
although the URL requires a password for access. The relevant URL's
are listed in the README.nfs file at ftp://ftp.us.kernel.org/, and
other kernel archive sites, along with login information. Patches are
at ftp://ftp.varesearch.com/pub/kernel/latest/patches/.

The source archives of the user-space server and utilities currently
reside on ftp://linux.mathematik.tu-darmstadt.de:/pub/linux/people/
okir/.

In the case of older Solaris releases, the lack of statd or lockd on
a client or server machine may cause incompatibility. On some
versions of Solaris, statd can be used to exploit features of the
automounter. Sun released a patch to correct this, but statd still
needs to be started by root on such systems. On recent Solaris
systems, refer to the information in /etc/dfs/dfstab and the share
(1M) manual page to enable volume sharing. In addition, the rpcinfo
program can tell you if statd or lockd are available on the local or
remote machines.

The linux-kernel mailing list has on-and-off discussions of the
status of the NFS subsystem, which appears to be changing rapidly.

4.12. Can I Use True Type Fonts with Linux?

Yes. There are a number of True Type font servers for the X Window
System. One of them is xfsft. Its home page is http://
www.dcs.ed.ac.uk/home/jec/programs/xfsft/. There are also
instructions for configuration.

People have reported success with other True Type font servers. There
are links from the xfsft Home Page to them as well.

You can also compile True Type Font support into your X server
directly. Again, refer to the xfsft Home Page for details.

4.13. How Can I Boot Linux from MS-DOS?

If LILO doesn't work, and if the machine has MS-DOS or Microsoft
Windows, you may be left with a computer that won't boot. This can
also happen on an upgrade to your Linux distribution. Re-installing
LILO is the last thing that the installation does. So it is vitally
important when installing or upgrading Linux on a dual boot machine,
to have a MS-DOS or Windows rescue disk nearby so you can FDISK -MBR.
Then you can go about using LOADLIN.EXE instead of LILO.

This config.sys file is one possible way to invoke LOADLIN.EXE and
boot MS-DOS or Linux.

[menu]                                                                 
menuitem=DOS, Dos Boot                                                 
menuitem=LINUX, Linux Boot                                             
                                                                       
[LINUX]                                                                
shell=c:\redhat\loadlin.exe c:\redhat\autoboot\vmlinuz vga=5 root=/dev 
                                                                       
[DOS]                                                                  
STACKS = 0,0                                                           
rem all the other DOS drivers get loaded here.                         

This creates a menu where you can directly jump to LOADLIN.EXE before
all of the MS-DOS drivers get loaded.

The paths and options are peculiar to one machine and should be
intuitively obvious to the most casual observer. See the LOADLIN.EXE
docs for options. They are the same as LILO, and options are just
passed to the kernel, anyhow.
