  * The configuration of pppd, the program that maintains the actual
    connection, is usually contained in two or three separate files.
    The first is usually /etc/ppp/options, which contains options
    that all of your system's PPP connections will use. (Yes, you can
    have more than one; as many as your computer has serial ports,
    generally.)
   
    Here is a sample /etc/ppp/options file:
   
    # /etc/ppp/options                                        
                                                              
    asyncmap 0                                                
    auth                                                      
    crtscts                                                   
    lock                                                      
    noipx                                                     
                                                              
    # ---<End of File>---                                     
   
    The options may be given on one line or each on a separate line.
    Many options files are much longer, and come with a description
    of each option. Here, the options mean, in order, don't remap any
    characters between the PPP client and server; always use
    password, PAP, or CHAP authentication when making a connection;
    use the modem's hardware handshake lines for flow control; lock
    the serial port when in use so no other programs can access it;
    and do not use the IPX network protocol.
   
  * For connection set-up on each individual serial port or PPP host,
    there will either be an /etc/ppp/options.ttyS1, for example,
    options file for /etc/ttyS1, or a file for your ISP in the /etc/
    ppp/peers directory. The default is often called /etc/ppp/peers/
    provider. Here is a sample of the default provider file:
   
    noauth                                                    
    connect "/usr/sbin/chat -v -f /etc/chatscripts/provider"  
    defaultroute                                              
    /dev/ttyS1                                                
    38400                                                     
    persist                                                   
   
    There might be an explanation of these and other options in the /
    etc/ppp/peers/provider file itself. You can also refer to the 
    pppd manual page for details. Briefly, they mean: do not use PAP
    authentication for this connection; use the chat program and the
    /etc/chatscripts/provider script, which is described above, to
    dial the phone and log in; set the network default route to the
    PPP connection (so when your network software needs to resolve an
    network address that is not on your local machine(s), it will use
    the PPP connection to the Internet); use /dev/ttyS1 as the serial
    port for the connection; set the modem speed to 38400; and keep
    the pppd daemon running even if the connection fails.
   
  * That is all of the configuration you need. To actually start and
    stop PPP, there are often /usr/bin/pon and /usr/bin/poff scripts
    (in Debian), or something similar, and they are usually very
    simple, and only contain the command:
   
    /usr/sbin/pppd call ${1:-provider}                        
   
    This will start pppd and use the call option to call the server
    that you type on the command line, or the provider given in the /
    etc/ppp/peers/provider file if you do not specify a remote
    server. After making the call and logging in (about 30 seconds),
    you should be able to use the /sbin/ifconfig program to determine
    that the connection really did establish a PPP interface (the
    first will be ppp0, the second will be ppp1, etc., depending on
    how many simultaneous PPP connections you have. If something goes
    wrong, you can look at the /var/log/ppp.log file to determine
    what happened. You can also view the log as the connection is
    being made, by "tailing" it in another window; that is, viewing
    it as pppd logs the connection's status information. To do this,
    use the command (again, as root):
   
    tail -f /var/log/ppp.log                                  
   
    On some systems the PPP output is directed to /var/log/messages,
    in which case your system may not have a dedicated PPP log file.
   

You should be also able to ping one of your ISP's domain names (e.g.,
mail.isp.com) and receive a response.

These are the most basic steps for configuring a PPP connection. You
will also need to take into account what other network connections
may be present (for example, if there's an Ethernet connection that
has already been assigned the default route), as well as various
security measures at your ISP's end. If you're having trouble making
the dial-up connection, usually the best way to determine what may be
going wrong is to use Seyon, minicomm, kermit, or some other program
to dial and log in manually to the ISP, and determine just exactly
what you have to do to log in, then duplicate that in the PPP
scripts.

Most Linux documentation also has additional instructions for
configuring PPP connections. Refer to ("Where Can I Get Linux
Material by FTP?") ("Where Can I Get the HOWTO's and Other
Documentation?")
=====================================================================

8.10. What Version of Linux and What Machine Name Am I Using?

Type:

uname -a                                                             
=====================================================================

8.11. What is a "core" File?

A core file is created when a program does something, "wrong," due to
a bug, or which violates the operating system or hardware protection
mechanisms. The operating system kills the programs and creates a
core file that programmers can use to figure out what went wrong. It
contains a detailed description of the state that the program was in
when it died.

If would like to determine what program a core file came from, use
the file command, like this:

file core                                                            

That will tell you the name of the program that produced the core
dump. You may want to write the maintainer(s) of the program, telling
them that their program dumped core.

[Eric Hanchrow]
=====================================================================

8.12. How Can I Enable or Disable Core Dumps?

By using the ulimit command in bash, the limit command in tcsh, or
the rlimit command in ksh. See the appropriate manual page for
details.

This setting affects all programs run from the shell (directly or
indirectly), not the whole system.

If you wish to enable or disable core dumping for all processes by
default, you can change the default setting in linux/sched.h--see the
definition of INIT_TASK, and look also in linux/resource.h.

PAM support optimizes the system's environment, including the amount
of memory a user is allowed. In some distributions this parameter is
configurable in the /etc/security/limits.conf file. For more
information, refer to the Linux Administrator's Security Guide. ("
Where Can I Get the HOWTO's and Other Documentation?")
=====================================================================

8.13. How Do I Upgrade/Recompile My Kernel?

See the Kernel HOWTO or the README files which come with the kernel
release on ftp.cs.helsinki.fi/pub/Software/Linux/Kernel/ and mirrors.
(See "Where Can I Get Linux Material by FTP?") You may already have a
version of the kernel source code installed on your system, but if it
is part of a standard distribution it is likely to be somewhat out of
date (this is not a problem if you only want a custom configured
kernel, but it probably is if you need to upgrade.)

With newer kernels you can (and should) make all of the following
targets. Don't forget that you can specify multiple targets with one
command.

make clean dep install modules modules_install                       

Also remember to update the module dependencies.

depmod -a                                                            

This command can be run automatically at boot time. On Debian/GNU
Linux systems, the command is part of the /etc/init.d/modutils
script, and can be linked appropriately in the /etc/rcx.d/
directories. For more information on depmod, see the manual page.

Make sure you are using the most recent version of the modutils
utilities, as well as all other supporting packages. Refer to the
file Documentation/Changes in the kernel source tree for specifics,
and be sure to consult the README file in the modutils package.

Remember that to make the new kernel boot you must run lilo after
copying the kernel into your root partition--the Makefile in some
kernels have a special zlilo target for this; try:

make zlilo                                                           

On current systems, however, you can simply copy the zImage or
bzImage file (in arch/i386/boot/ to the /boot/ directory on the root
file system, or to a floppy using the dd command. Refer also to the
question, How do I get LILO to boot the kernel image?

Kernel version numbers with an odd minor version (ie, 1.1.x, 1.3.x)
are the testing releases; stable production kernels have even minor
versions (1.0.x, 1.2.x). If you want to try the testing kernels you
should probably subscribe to the linux-kernel mailing list. ("What
Mailing Lists Are There?")

The Web site http://www.kernelnotes.org/ has lots of information and
links to other sites that provide information about Linux kernel
updates.

Also refer to the questions, "I Upgraded the Kernel and Now My PCMCIA
Card Doesn't Work." and "How Do I Get LILO to Boot the Kernel Image?"
=====================================================================

8.14. Can I Have More than 3 Serial Ports by Sharing Interrupts?

Yes, but you won't be able to use simultaneously two ordinary ports
which share an interrupt (without some trickery). This is a
limitation of the ISA Bus architecture. See the Serial HOWTO for
information about possible solutions and workarounds for this
problem.
=====================================================================

8.15. How Do I Update (For Example) the System's Perl Documentation?

Because program source and documentation files accumulate on machines
that have been in operation for a long time (like McGee's closet),
it's a good idea to get acquainted with the "*nix way of doing
things" (TM) to make sure that you know what's on your system. In
short, let the computer do it for you in the background.

The following bash shell script uses the programs find, egrep, and 
sed to search directory hierarchies for the text string =head1, which
signals the start of a Perl POD (Plain Old Documentation) module. It
then constructs and executes a shell script to generate the formatted
documentation from those files.

The programs that do the actual formatting are pod2man and pod2text.
They are Perl scripts that call Perl library modules. The programs 
pod2latex and pod2html can also be added to the script, if they're
present on the system. Place the shell script below in a file called 
makepods, and then make the file executable with the shell command:

chmod +x makepods                                                    

Then you should be able to execute it in the current directory with
the command:

./makepods                                                           

snip here

....................................................................   

Because the shell script searches entire directory hierarchies, it
may take a while to run.

If you're the system administrator, the shell script can be made part
of a cron job to be run weekly, monthly, or at some other interval,
and inform you by E-mail of any errors that occurred. If the makepods
script is in /usr/local/sbin/, for example, and you want the
formatted documentation to be saved in a subdirectory of /usr/local/
doc/, then the following shell script can be called by cron if you
save it (on this system) in /etc/cron.d/Weekly/:

#!/bin/sh                                                            
cd /usr/local/doc/perl/formatted-pods                                
/usr/local/sbin/makepods 2>/tmp/mpds.err                             
mail -s 'Error output of makepod ' root </tmp/mpds.err               
rm -f /tmp/mpds.err                                                  

Remember to run chmod +x to make this shell script executable as
well. This is an example only; it is not the only way that cron jobs
can be configured. Please consult your local documentation, YMMV

8.16. How Do I Configure Emacs to Start with My Default Settings?

Create a file in your home directory named .emacs with the Emacs Lisp
commands that you want to run every time Emacs starts up. You won't
see the file in the directory listing. (The leading '.' tells ls not
to display it, unless you use the -a command line switch with ls.)

Any kind of Emacs Lisp statement will work in the .emacs file,
including entire defuns. Emacs uses lisp variables and statements
extensively, and many of the editing functions are written in Emacs
Lisp. For example, to enable word wrapping whenever you edit a file
that ends with .txt, add the following statement. This is from the
Emacs Texinfo help document ( F1-i, then m Emacs Return):

(add-hook text-mode-hook                                             
        '(lambda () (auto-fill-mode 1)))                             

This adds a statement that calls a hook function whenever a text
editing mode is entered for that buffer. The value of text-mode-hook,
which is a variable, to auto-fill-mode, which is a function.

If you want to turn off the menu bar at the top of each Emacs frame,
add this statement:

(menu-bar-mode -1)                                                   

And if you want to include an Emacs Lisp program that someone has
written, like msb.el (an enhanced, pop-up buffer menu), make sure the
lisp file is in a directory where Emacs can find it (usually it will
be named Site-lisp), and add these statements in the .emacs file:

(require 'msb)                                                       
(msb-mode 1)                                                         

Most tasks have several possible solutions in Emacs Lisp. Any task
that can be programmed in Emacs Lisp is valid in the .emacs file. For
more information, consult the Texinfo documentation. There is also a
FAQ list for Emacs (refer to What other FAQ's are there for Linux? ).
=====================================================================

8.17. How Do I Make a Rescue Floppy?

Make a file system on it with bin, etc, lib and dev
directories--everything you need. Install a kernel on it and arrange
to have LILO boot it from the floppy (see the LILO documentation, in
lilo.u.*.ps).

If you build the kernel (or tell LILO to tell the kernel) to have a
RAM disk the same size as the floppy the RAM disk will be loaded at
boot time and mounted as root in place of the floppy.

See the Bootdisk HOWTO.
=====================================================================

8.18. How Do I Remap My Keyboard to UK, French, Etc.?

For recent kernels, get /pub/Linux/system/Keyboards/kbd-0.90.tar.gz
from ftp://metalab.unc.edu/. Make sure you get the appropriate
version; you have to use the right keyboard mapping package for your
kernel version. For older kernels you have to edit the top-level
kernel Makefile, in /usr/src/linux/. You may find more helpful
information in The Linux Keyboard and Console HOWTO, by Andries
Brouwer, at ftp://metalab.unc.edu/pub/Linux/docs/HOWTO/.
=====================================================================

8.19. How Do I Get NUM LOCK to Default to On?

Use the setleds program, for example (in /etc/rc.local or one of the
/etc/rc.d/* files):

for t in 1 2 3 4 5 6 7 8                                             
do                                                                   
 setleds +num < /dev/tty$t > /dev/null                               
done                                                                 

setleds is part of the kbd package ("How do I remap my keyboard to
UK, French, etc.? "). Alternatively, patch your kernel. You need to
arrange for KBD_DEFLEDS to be defined to (1 << VC_NUMLOCK) when
compiling drivers/char/keyboard.c.
=====================================================================

8.20. How Do I Set (Or Reset) My Initial Terminal Colors?

The following shell script should work for VGA consoles:

for n in 1 2 4 5 6 7 8; do                                           
     setterm -fore yellow -bold on -back blue -store > /dev/tty$n    
     done                                                            

Substitute your favorite colors, and use /dev/ttyS$n for serial
terminals.

To make sure they are reset when people log out (if they've been
changed):

Replace the references to getty (or mingetty or uugetty or whatever)
in /etc/inittab with references to /sbin/mygetty.

#!/bin/sh                                                            
setterm -fore yellow -bold on -back blue -store > $1                 
exec /sbin/mingetty $@

=====================================================================

8.21. How Can I Have More Than 128Mb of Swap?

Use several swap partitions or swap files--Linux supports up to 16
swap areas, each of up to 128Mb.

Very old kernels only supported swap partition sizes up to 16Mb.

Linux on machines with 8KB paging, like Alpha and Sparc64, support a
swap partition up to 512MB. The 128MB limitation comes from PAGE_SIZE
*BITSPERBYTE on machines with 4KB paging, but is 512KB on machines
with 8KB paging. The limit is due to the use of a single page
allocation map.

The file mm/swapfile.c has all of the gory details.

[Peter Moulder, Gordon Weast]
=====================================================================

9. Miscellaneous Information and Questions Answered

9.1. How Do I Program XYZ Under Linux?

Read the manuals, or a good book on Unix and the manual pages (type
man man). There is a lot of GNU Info documentation, which is often
more useful as a tutorial. Run Emacs and type F1-i, or type info info
if you don't have or don't like Emacs. Note that the Emacs libc node
may not exactly describe the latest Linux libc, or GNU glibc2. But
the GNU project and LDP are always looking for volunteers to upgrade
their library documentation.

Anyway, between the existing Texinfo documentation, and the manual
pages in sections 2 and 3, should provide enough information to get
started.

As with all free software, the best tutorial is the source code
itself.

The latest release of the Linux manual pages, a collection of useful
GNU Info documentation, and various other information related to
programming Linux, can be found on metalab.unc.edu/pub/Linux/docs/
man-pages/.
=====================================================================

9.2. What's All This about ELF? glibc?

See the ELF HOWTO by Daniel Barlow--note, this is not the file
move-to-elf, which is a blow-by-blow account of how to upgrade to ELF
manually.

Linux has two different formats for executables, object files, and
object code libraries, known as, "ELF." (The old format is called
"a.out.") They have advantages, including better support for shared
libraries and dynamic linking.

Both a.out and ELF binaries can coexist on a system. However, they
use different shared C libraries, both of which have to be installed.

If you want to find out whether your system can run ELF binaries,
look in /lib for a file named, "libc.so.5." If it's there, you
probably have ELF libraries. If you want to know whether your
installation actually is ELF you can pick a representative program,
like ls, and run file on it:

-chiark:~> file /bin/ls                                              
/bin/ls: Linux/i386 impure executable (OMAGIC) - stripped            
                                                                     
valour:~> file /bin/ls                                               
/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1, stripped 

There is a patch to get 1.2.x to compile using the ELF compilers, and
produce ELF core dumps, at ftp://tsx-11.mit.edu/pub/packages/GCC/.
You do not need the patch merely to run ELF binaries. 1.3.x and later
do not need the patch at all.

The GNU glibc2 libraries are essentially more recent versions of ELF
libraries that follow most of the same processes for dynamic linking
and loading. Upgrade information is contained in ("How Do I Upgrade
the Libraries without Trashing My System?")
=====================================================================

9.3. How Do I Determine What Packages Are Installed on My System?

For distributions that use RPM format packages, use the command:

# rpm -qa                                                            

You need to be logged in as root. You can save the output to a text
file for future reference, a command like:

# rpm -qa >installed-packages                                        

For Debian systems, the equivalent command is:

# dpkg -l                                                            
=====================================================================

9.4. What Is a .gz file? And a .tgz? And .bz2? And... ?

.gz (and .z) files are compressed using GNU gzip. You need to use 
gunzip (which is a symlink to the gzip command that comes with most
Linux installations) to unpack the file.

.taz, .tar.Z, and .tz are tar files (made with tar) and compressed
using compress. The standard *nix compress is proprietary software,
but free equivalents like ncompress exist.

.tgz (or .tpz) is a tar file compressed with gzip.

.bz2 is a file compressed by the more recently introduced (and
efficient) bzip2.

.lsm is a Linux Software Map entry, in the form of a short text file.
Details about the LSM project and the LSM itself are available in the
subdirectory on ftp://metalab.unc.edu/pub/Linux/docs/.

.deb is a Debian Binary Package--the binary package format used by
the Debian GNU/Linux distribution. It is manipulated using dpkg and 
dpkg-deb (available on Debian systems and from ftp://ftp.debian.org//
).

.rpm is a Red Hat RPM package, which is used in the Red Hat and
similar distributions.

The file command can often tell you what a file is.

If you find that gzip complains when you try to uncompress a file,
you probably downloaded it in ASCII mode by mistake. You must
download most things in binary mode--remember to type "binary" as a
command in FTP before using, "get," to download the file.
=====================================================================

9.5. What Does VFS Stand For?

Virtual File System. It's the abstraction layer between the user and
real file systems like ext2, Minix and MS-DOS. Among other things,
its job is to flush the read buffer when it detects a disk change on
the floppy disk drive.

VFS: Disk change detected on device 2/0                              
=====================================================================

9.6. What is a BogoMip?

"BogoMips" is a combination of Bogus and Mips. MIPS stands for
(depending on who you ask) Millions of Instructions per Second, or
Meaningless Indication of Processor Speed.

The number printed at boot time is the result of a kernel timing
calibration, used for very short delay loops by some device drivers.

According to the BogoMips mini-HOWTO, the rating for your machine
will be:

9.8. How Many People Use Linux?

Linux is freely available, and no one is required to register with
any central authority, so it is difficult to know. Several businesses
survive solely on selling and supporting Linux. Linux news groups are
some of the most heavily read on Usenet. Accurate numbers are hard to
come by, but the number is almost certainly in the millions.

However, people can register as Linux users at the Linux Counter
project, which has been in existence since 1993. In August, 1998, the
project counted more than 70,000 users.

Visit the Web site at http://counter.li.org/ and fill in the
registration form. If you don't want to use the Web, send E-mail to 
mailto:[EMAIL PROTECTED] with the subject line, "I use Linux at
home," or "I use Linux at work."

The current count is posted monthly to comp.os.linux.misc, and is
always available from the Web site.

=====================================================================

9.9. How Many People Use Linux? (Redux.)

In 1999, International Data Corporation released its first commercial
forecast of Linux sales. The report quantifies Linux vendor sales in
1996, 1997, and 1998, and forecasts through the year 2003.

To obtain the report, contact IDC at mailto:[EMAIL PROTECTED]. Their

9.10. How Should I Pronounce Linux?

This is a matter of religious debate, of course!

If you want to hear Linus himself say how he pronounces it, download
english.au or swedish.au from ftp.funet.fi/pub/Linux/PEOPLE/Linus/
SillySounds/. If you have a sound card or the PC-speaker audio driver
you can hear them by typing

cat english.au >/dev/audio                                           

The difference isn't in the pronunciation of Linux but in the
language Linus uses to say, "hello."

For the benefit of those who don't have the equipment or inclination:
Linus pronounces Linux approximately as Leenus, where the "ee" is
