Joerg Wunsch 5320fd40a2 Add a description of how to setup sendmail for use with UUCP. 
Ideally, this should go into the ``mail'' section of the handbook, but
i don't have the time to write all of this right now, so i've put it
into the FAQ.

<p>
Welcome to the FreeBSD 2.X FAQ ! This document tries to answer
some of the most frequently asked questions about FreeBSD 2.X (or
later, unless specifically indicated). If there's something you're
having trouble with and you just don't see it here, then please
send mail to:
<url url="mailto:questions@FreeBSD.ORG" name="FreeBSD-questions
Mailing list"> or to <url url="mailto:faq@FreeBSD.ORG"
name="FreeBSD FAQ mailing list">
The latest released version is FreeBSD 2.1.0R. FreeBSD-current
refers to the future FreeBSD 2.2. The 2.1 release has been issued
from a special branch of the -current sources and is intended as a
even more stable version of 2.0.5.
There are regular snapshots extracted from 2.2-CURRENT. Check on
<tt>ftp.FreeBSD.ORG</tt> in <tt>/pub/FreeBSD/*-SNAP*</tt>.
Some of the instructions here will also refer to auxiliary
utilities in the <tt>/usr/share/FAQ/Text</tt> directory. If you do
not have this directory, or if it does not contain the file that
you want, you are probably using a version of FreeBSD prior to
2.0.5R. In this case, install the FreeBSD sources and look in
<tt>/usr/src/share/FAQ/Text</tt> (instead of
<tt>/usr/share/FAQ</tt>). CDROM purchasers and net folks who've
grabbed the FreeBSD 2.X ``<tt/srcdist/'' will have these files. If
you don't have the source distribution, then you can either grab
the whole thing from:
<url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/FreeBSD-current"
name="FreeBSD-current base directory">
Or you can grab only those files you're interested in straight out
of the FreeBSD-current distribution in:
<url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/FreeBSD-current/src"
name="FreeBSD-current src directory">

<heading>What is FreeBSD?</heading>
<p>
FreeBSD 2.X is a UN*X type operating system based on
U.C. Berkeley's 4.4BSD-lite release for the i386 platform. It is
also based indirectly on William Jolitz's port of U.C. Berkeley's
Net/2 to the i386, 386BSD. There have been many additions and
bug fixes made throughout the entire system, some of the
highlights of which are:
<itemize>
<item>More robust and extensive PC device support
<item>System V-style IPC, messaging and semaphores
<item>Shared Libraries
<item>Much improved virtual memory code
<item>Better console driver support
<item>Network booting (diskless) support
<item>YP support
<item>Full support of the PCI bus
<item>Loadable kernel modules
<item>Serial Console Support
<item>Merged VM/Buffer Cache
<item>On demand PPP
<item>Sync PPP
<item>Improved SCSI support
</itemize>
<sect1>
<heading>What do I need to run FreeBSD?</heading>
<p>
You'll need a 386 or better PC, with 4 Mo or more of RAM and at
least 60 MB of hard disk space. It can run with a low end MDA
card but to run X11R6, a VGA or better video card is needed.
See the section on <ref id="hardware" name="Hardware compatibility">

<heading>What are the various FreeBSD news groups?</heading>
<p>
There are two newsgroups currently dedicated to FreeBSD:
<descrip>
<tag/comp.unix.bsd.freebsd.announce/ For announcements
<tag/comp.unix.bsd.freebsd.misc/ General discussion
</descrip>
The following newsgroups may also be of interest to
general BSD enthusiasts:

General BSD topics
</descrip>
To setup/run your own News server or just reading Usenet News,
you may have a look at various packages already ported for
FreeBSD 2.X in <tt>/usr/ports/news</tt>. You'll find Cnews, INN,
Trn, TIN and others there.
For French-speaking people, the <tt/fr.comp.os.bsd/ group is for
you. Ask your system administrator if you don't receive this
group.
</sect1>
<sect1>
<heading>Books on FreeBSD</heading>
<p>
There currently aren't any books written specifically for
FreeBSD, although some people are supposedly working on some.
The FreeBSD Documentation Project exists, you may contact (or
better join them) on the <tt>doc</tt> mailing list:
<url url="mailto:doc@FreeBSD.ORG" name="&lt;doc@FreeBSD.ORG&gt;">.
A FreeBSD ``handbook'' is being created, and can be found as:
<url url="http://www.freebsd.org/How/handbook/" name="FreeBSD's Handbook">
Note that this is a work in progress, and so parts may be incomplete.
However, as FreeBSD 2.X is based upon Berkeley 4.4BSD-Lite, most
of the 4.4BSD manuals are applicable to FreeBSD 2.X. O'Reilly
and Associates publishes these manuals:

A good book on system administration is:
Evi Nemeth, Garth Snyder, Scott Seebass &amp; Trent R. Hein,<newline>
``Unix System Administration Handbook'', Prentice-Hall, 1995<newline>
ISBN: 0-13-151051-7<newline>
<bf/NOTE/ make sure you get the second edition, with a red cover,
instead of the first edition.
This book covers the basics, as well as TCP/IP, DNS, NFS,
SLIP/PPP, sendmail, INN/NNTP, printing, etc.. It's expensive
(approx. US&dollar;45-&dollar;55), but worth it. It also
includes a CDROM with the sources for various tools; most of
these, however, are also on the FreeBSD 2.1.0R CDROM (and the
FreeBSD CDROM often has newer versions).
<sect1>
<heading>Other sources of information.</heading>
<p>
One good source of additional information is the
``&lsqb;comp.unix.bsd&rsqb; NetBSD, FreeBSD, and 386BSD (0.1)

FAQ is posted around twice a month to the following newsgroups:

<heading>Copyrights</heading>
<p>
The goals of the FreeBSD Project are to provide software that may
be used for any purpose and without strings attached. Many of us
have a significant investment in the code (and project) and would
certainly not mind a little financial renumeration now and then,
but we're definitely not prepared to insist on it. We believe
that our first and foremost "mission" is to provide code to any
and all comers, and for whatever purpose, so that the code gets
the widest possible use and provides the widest possible benefit.
This is, I believe, one of the most fundamental goals of Free
Software and one that we enthusiastically support.
That code in our source tree which falls under the GNU Public License
(GPL) or GNU Library Public License (GLPL) comes with slightly more
strings attached, though at least on the side of enforced
access rather than the usual opposite. Due to the additional
complexities that can evolve in the commercial use of GPL software,
we do, however, endeavor to replace such software with submissions
under the more relaxed BSD copyright whenever possible.

<heading>How do I install FreeBSD?</heading>
<p>
<bf/IMPORTANT NOTE/ if you are installing 2.1.0R from tape, see
the question titled,
<ref id="install-tape" name="Help! I can't install from tape!">
Installation instructions can be found as:
<url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/2.1.0-RELEASE/INSTALL"
name="INSTALL from 2.1.0R">
Release notes are also available as:
<url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/2.1.0-RELEASE/RELNOTES"
name="RELNOTES from 2.1.0R">
On the CDROM, the following files are in the top-most directory:

<sect1>
<heading>I have only 4 MB of memory in this machine. Can I install FreeBSD 2.1.0 ?</heading>
<p>
FreeBSD 2.1.0 does not install with 4 MB. To be exact: it does
not install with 640 kB base + 3 MB extended memory. If your
motherboard can remap some of the ``lost'' memory out of the
640kB to 1MB region, then you may still be able to get FreeBSD
2.1.0 up.
Try to go into your BIOS setup and look for a ``remap'' option.
Enable it. You may also have to disable ROM shadowing.
It may be easier to get 4 more MB just for the install. Build a
custom kernel with only the options you need and then get the 4
MB out again.
You may also install 2.0.5 and then upgrade your system to 2.1.0
with the ``upgrade'' option of the 2.1.0 installation program.
After the installation, if you build a custom kernel, it will run
in 4 MB. Someone has even succeeded in booting with 2 MB (the
system was almost unusable though :-))
<sect1>
<heading>Help! I have no space! Do I need to delete everything first?</heading>
<p>
If your machine is already running DOS and has little or no free
space available for FreeBSD's installation, all is not lost! You
may find the ``<tt/FIPS/'' utility, provided in the
<tt>tools/</tt> subdirectory on the FreeBSD CDROM or on the
various FreeBSD ftp sites, to be quite useful.
<tt/FIPS/ allows you to split an existing DOS partition into two
pieces, preserving the original partition and allowing you to
install onto the second free piece. You first ``defrag'' your
DOS partition, using the DOS 6.xx <tt/DEFRAG/ utility or the
Norton Disk tools, then run <tt/FIPS/. It will prompt you for
the rest of the information it needs. Afterwards, you can reboot
and install FreeBSD on the new free slice. See the Distributions
menu for an estimation of how much free space you'll need for the
kind of installation you want.
NOTE: <tt/FIPS/ may cause problems with the mounting of your
DOS partition under FreeBSD 2.X.
<sect1>
<heading>I have installed Windows 95 on to my home PC, and I want
to also install FreeBSD.</heading>
<p>
Install Windows 95 first, after that FreeBSD. FreeBSD's boot
manager will then manage to boot Win95 and FreeBSD.
<sect1>
<heading>Can I use compressed DOS filesystems from FreeBSD?</heading>
<p>
No. If you are using a utility such as Stacker(tm) or
DoubleSpace(tm), FreeBSD will only be able to use whatever
portion of the filesystem you leave uncompressed. The rest of
the filesystem will show up as one large file (the
stacked/dblspaced file!). <bf/DO NOT REMOVE THAT FILE!/ You will
probably regret it greatly!
It is probably better to create another uncompressed DOS primary
partition and use this for communications between DOS and
FreeBSD.
<sect1>
<heading>Can I mount my DOS extended partitions?</heading>
<p>
This feature isn't in FreeBSD 2.1 but should be in 2.2. We've
laid all the groundwork for making this happen, now we just need
to do the last 1% of the work involved.
<sect1>
<heading>Can I run DOS binaries under FreeBSD?</heading>
<p>
Not yet! We'd like to add support for this someday, but are
still lacking anyone to actually do the work. Ongoing work with
Linux's <tt/DOSEMU/ utility may bring this much closer to being a
reality sometime soon. Send mail to
<url url="mailto:hackers@freebsd.org"
name="The FreeBSD hackers list">
if you're interested in joining this effort!
However, there is a neat utility called ``<tt/pcemu/'' in the
ports collection which emulates an 8088 and enough BIOS services
to run DOS text mode applications. It requires the X Window
System (provided as XFree86 3.1.2).
<sect1>
<heading>Help! I can't install from tape! The install fails with a ``record too big'' error!<label id="install-tape"></heading>
<p>
If you are installing 2.1.0R from tape, you must create the tape
using a tar blocksize of 10 (5120 bytes). The default tar
blocksize is 20 (10240 bytes), and tapes created using this
default size cannot be used to install 2.1.0R; with these tapes,
you will get an error that complains about the record size being
too big.
<sect1>
<heading>I want to install FreeBSD onto a SCSI disk that has more than 1024 cylinders. How do I do it?</heading>
<p>
This depends. If you don't have DOS (or another operating
system) on the system, you can just keep the drive in native mode
and simply make sure that your root partition is below 1024 so
the BIOS can boot the kernel from it. It you also have DOS/some
other OS on the drive then your best bet is to find out what
parameters that it thinks you have before installing FreeBSD.
When FreeBSD's installation procedure prompts you for these
values, you should then enter them rather than simply going with
the defaults.
There is a freely available utility distributed with FreeBSD
called ``<tt/pfdisk/'' (located in the <tt>tools/dos-tools</tt>
subdirectory) which can be used for this purpose.

<sect1>
<heading>When I boot FreeBSD it says ``Missing Operating System''.</heading>
<p>
See question above. This is classically a case of FreeBSD and
DOS or some other OS conflicting over their ideas of disk
geometry. You will have to reinstall FreeBSD, but obeying the
instructions given above will almost always get you going.
<sect1>
<heading>When I install the boot manager and try to boot FreeBSD for the first time, it just comes back with the boot manager prompt again.</heading>
<p>
This is another symptom of the problem described in the preceding
question. Your BIOS geometry and FreeBSD geometry settings do
not agree! If your controller or BIOS supports cylinder
translation (often marked as ``&gt;1GB drive support''), try
toggling its setting and reinstalling FreeBSD.
<sect1>
<heading>I'm having lots of trouble trying to disklabel a new SCSI drive.</heading>
<p>I have made an entry in <tt>/etc/disktab</tt>, but
when I try to label the drive the following happens:
<verb>
mips# disklabel -w /dev/sd1 sea32550N
disklabel: ioctl DIOCWDINFO: Operation not supported by device
</verb>
What am I doing wrong?
Answer:<newline>
Doing this using <tt/disklabel/ (and <tt/fdisk/) is probably
harder than using <tt/sysinstall/. The following should work to
put FreeBSD-2.1.0 on the whole of an <bf/empty/ disk assuming that
the <tt/disktab/ entry is correct.
<verb>
disklabel -r -w /dev/rsd1 sea32550N
^^ ^
</verb>
The first <tt/-r/ is essential for writing new labels and using
the raw device instead of the block device is good technique. To
be ``empty'' the disk should have 0's at critical points on the
first two sectors. In particular, the 2 byte signature at the
end of the first sector must not be <tt/0xaa55/ or the disk will
be interpreted as having a slice (partition) table and it will be
difficult to write to it where you want unless the slice table is
initialized correctly. All bootable hard disks will have the
<tt/0xaa55/ signature so they won't be empty. Empty disks may be
created by copying zeros over the first 2 sectors:
<verb>
dd if=/dev/zero of=/dev/rsd1 bs=1k count=1
</verb>
Note that this will (appear to) destroy all data on the disk.
The above is not the best method. Normally you will have a slice
table or a label that you want to preserve or modify slightly.
This can be done using
<verb>
fdisk -u /dev/rsd1 # install or change slice table
disklabel -r -w sd1 sea32550N # install label
^no /dev/r
</verb>
<tt/fdisk/ is unintuitive and has poor error handling so it is
difficult to change slice tables using it. However, to install a
new slice table on an empty drive you just have to accept all the
defaults except for ``n'' to write at the end.
Note that the <tt/sd1/ drive in the above is different from
<tt>/dev/rsd1</tt>. <tt/disklabel/ modifies path names that
don't start with a slash by prefixing <tt>/dev/r</tt> and
suffixing the ``raw'' partition letter. <tt/sd1/ thus means
<tt>/dev/rsd1c</tt>, i.e., the ``<tt/c/'' partition on the first
BSD slice on drive <tt/sd1/, i.e., the whole of the first BSD
slice on drive sd1, while <tt>/dev/rsd1</tt> is the whole of
drive sd1. Thus ``<tt>disklabel ... sd1</tt>'' will fail if
there is no FreeBSD slice, while ``<tt>disklabel /dev/rsd1</tt>''
will print the in-core label for the whole drive. Oops, this
assumes that slices are enabled by the 0xaa55 signature. If
slices aren't enabled, then /dev/rsd1c means the whole drive. In
practice, slices have to be enabled to make the disk bootable.
If there are no BSD slices, then <tt>/dev/rsd1c</tt> will be
empty instead of unconfigured and attempts to label <tt/sd1/ will
fail with a bogus error message about <tt>/dev/rsd1c</tt> not
existing.
<tt>/dev/sd1</tt> didn't exist in previous versions of FreeBSD or
386BSD so your ``<tt>disklabel -w /dev/sd1 ...</tt>'' would have
printed a less confusing error message before failing.
<verb>
The disklabel I'm trying is
sea32550N|Seagate 32550N:\
:ty=winchester:dt=SCSI:se#512:nc#3510:nt#11:ns#108:\
:rm#7200:\
:pa#2433024:oa#0:ta=4.2BSD:\
:pc#4169880:oc#0:
</verb>
Note that <tt/ns/ has to be < 64 in the slice table. I would use
<tt/nt&num;22:ns&num;54/. This only matters if you don't accept
<tt/fdisk/'s default (bogus) slice table. You have to use a
valid table if you want multiple slices, or the first slice
starting at a nonzero offset. Starting a nonempty slice at
offset 0 is invalid so <tt/sysinstall/ doesn't support creating
such slices.
<sect1>
<heading>I have an IDE drive with lots of bad blocks on it and FreeBSD doesn't seem to install properly.</heading>
<p>
FreeBSD's bad block (the ``<tt/bad144/'' command) handling is
still not 100&percnt; (to put it charitably) and it must
unfortunately be said that if you've got an IDE or ESDI drive
with lots of bad blocks, then FreeBSD is probably not for you!
That said, it does work on thousands of IDE based systems, so
you'd do well to try it first before simply giving up.
IDE drives are <em/supposed/ to come with built-in bad-block
remapping; if you have documentation for your drive, you may want
to see if this feature has been disabled on your drive. However,
ESDI, RLL, and ST-506 drives normally do not do this.
<sect1>
<heading>I have 32MB of memory, should I expect any special problems?<label id="bigram"></heading>
<p>
No. FreeBSD 2.X comes with bounce buffers which allows your bus
mastering controller access to greater than 16MB.
<sect1>
<heading>My network card keeps getting errors like, ``<tt/ed1: timeout/''. What's going on?</heading>
<p>
This is usually caused by an interrupt conflict (e.g., two boards
using the same IRQ). FreeBSD prior to 2.0.5R used to be tolerant
of this, and the network driver would still function in the
presence of IRQ conflicts. However, with 2.0.5R and later, IRQ
conflicts are no longer tolerated.
<sect1>
<heading>Do I need to install the complete sources?</heading>
<p> In general, no. However, we would strongly recommend that you
install, at a minimum, the ``<tt/base/'' source kit, which
includes several of the files mentioned here, and the
``<tt/sys/'' (kernel) source kit, which includes sources for the
kernel. There is nothing in the system which requires the
presence of the sources to operate, however, except for the
kernel-configuration program <tt/config(8)/. With the exception
of the kernel sources, our build structure is set up so that you
can read-only mount the sources from elsewhere via NFS and still
be able to make new binaries. (Because of the kernel-source
restriction, we recommend that you not mount this on
<tt>/usr/src</tt> directly, but rather in some other location
with appropriate symbolic links to duplicate the top-level
structure of the source tree.)
Having the sources on-line and knowing how to build a system with
them will make it much easier for you to upgrade to future
releases of FreeBSD.

<heading>DES encryption software can not be exported from the United States. If I live outside the US, how can I encrypt passwords?</heading>
<p> If it is not absolutely imperative that you use DES style
encryption, you can use FreeBSD's default encryption for even
<bf/better/ security, and with no export restrictions. FreeBSD
2.0's password default scrambler is now <bf/MD5/-based, and is
more CPU-intensive to crack with an automated password cracker
than DES.
Since the DES encryption algorithm cannot legally be exported
from the US, non-US users should not download this software (as
part of the <tt/secrdist/ from US FTP sites.
There is however a replacement libcrypt available, based on
sources written in Australia by David Burren. This code is now
available on some non-US FreeBSD mirror sites. Sources for the
unencumbered libcrypt, and binaries of the programs which use it,
can be obtained from the following FTP sites:
<descrip>
<tag/South Africa/
<tt>ftp://ftp.internat.freebsd.org/pub/FreeBSD</tt><newline>
<tt>ftp://storm.sea.uct.ac.za/pub/FreeBSD</tt>
<tag/Brazil/
<tt>ftp://ftp.iqm.unicamp.br/pub/FreeBSD</tt>
<tag/Finland/
<tt>ftp://nic.funet.fi/pub/unix/FreeBSD/eurocrypt</tt>
</descrip>
The non-US <tt/securedist/ can be used as a direct replacement
for the encumbered US <tt/securedist/. This <tt/securedist/
package is installed the same way as the US package (see
installation notes for details). If you are going to install DES
encryption, you should do so as soon as possible, before
installing other software.
Non-US users should please not download any encryption software
from the USA. This can get the maintainers of the sites from
which the software is downloaded into severe legal difficulties.
A non-US distribution of Kerberos is also being developed, and
current versions can generally be obtained by anonymous FTP from
<tt>braae.ru.ac.za</tt>.
There is a mailing list for the discussion of non-US encryption
software. For more information, send an email message with a
single line saying ``<tt/help/'' in the body of your message to
<tt>&lt;majordomo@braae.ru.ac.za&gt;</tt>.

FreeBSD supports ST-506 (sometimes called ``MFM''), RLL, and ESDI
drives, which are usually connected to WD-1002, WD-1003, or
WD-1006/7 controllers (although clones should also work).
FreeBSD also supports IDE and SCSI hard drives.

<heading>Does FreeBSD support the AHA-2xxx SCSI adapters from Adaptec?</heading>
<p>
FreeBSD supports the AHA-2xxx line of adapters. The GPL portions
of the old drivers have been re-written and now it is fully
under the Berkeley style copyright.
<sect1>
<heading>I have a Mumbleco bus mouse. Is it supported and if so, how do I set it up for XFree86?</heading>
<p>
FreeBSD supports the Logitech and ATI Inport bus mice. You need
to add the following line to the kernel config file and recompile
for the Logitech and ATI mice:
<verb>
device mse0 at isa? port 0x23c tty irq5 vector mseintr
</verb>
<sect1>
<heading>I have a PS/2 mouse (``keyboard'' mouse) (Alternatively: I have a laptop with a track-ball mouse). How do I use it?</heading>
<p>
You'll have to add the following lines to your kernel
configuration file and recompile:
<verb>
device psm0 at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr
# Options for psm:
options PSM_NO_RESET #don't reset mouse hardware (some laptops)
</verb>
<p>
See <url url="http://www.freebsd.org/handbook/kernelconfig.html"
name="configuring the kernel">
if you've no experience with building kernels.
Once you have a kernel detecting psm0 correctly at boot time,
make sure that an entry for psm0 exists in /dev. You can do this
by typing:
<verb>
cd /dev; sh MAKEDEV psm0
</verb>
When logged in as root.
<p>
Note: Some PS/2 mouse controllers have a problem
where the presence of the psm0 driver will cause the keyboard to
lock up (which is why this driver is not present by default in the
GENERIC kernel). This can sometimes be fixed by bouncing the
NumLock key during the boot process. Also suggest going into CMOS
setup and toggling any value for Numlock On/Off at boot time. The
real fix is, of course, to merge the PS/2 mouse driver with syscons.
Any volunteers? :)

<heading>What types of tape drives are supported under FreeBSD?</heading>
<p>
FreeBSD supports SCSI, QIC-02 and QIC-40/80 (Floppy based) tape
drives. This includes 8-mm (aka Exabyte) and DAT drives.
The QIC-40/80 drives are known to be slow.
<sect1>
<heading>What sound cards are supported by FreeBSD?</heading>
<p>
FreeBSD supports the SoundBlaster, SoundBlaster Pro, SoundBlaster
16, Pro Audio Spectrum 16, AdLib and Gravis UltraSound sound

<heading>I have a 386/486sx/486SLC machine without a math co-processor. Will this cause me any problems?</heading>
<p>
Generally no, but there are circumstances where you will take a
hit, either in performance or accuracy of the math emulation code
(see the section <ref id="emul" name="on FP emulation">). In
particular, drawing arcs in X will be VERY slow. It is highly
recommended that you buy a math co-processor; it's well worth it.
<bf/NOTE/ Some math co-processors are better than others. It pains
us to say it, but nobody ever got fired for buying Intel. Unless
you're sure it works with FreeBSD, beware of clones.

<heading>I cannot get my Bustek 742a EISA SCSI to be recognized by FreeBSD 2.1</heading>
<p>
This info is specific to the 742a but may also cover other
Buslogic cards. (Bustek = Buslogic)
There are 2 general ``versions'' of the 742a card. They are
hardware revisions A-G, and revisions H - onwards. The revision
letter is located after the Assembly number on the edge of the
card. The 742a has 2 ROM chips on it, one is the BIOS chip and
the other is the Firmware chip. FreeBSD doesen't care what
version of BIOS chip you have but it does care about what version
of firmware chip. Buslogic will send upgrade ROMS out if you
call their tech support dept. The BIOS and Firmware chips are
shipped as a matched pair. You must have the most current
Firmware ROM in your adapter card for your hardware revision.
The REV A-G cards can only accept BIOS/Firmware sets up to
2.41/2.21. The REV H- up cards can accept the most current
BIOS/Firmware sets of 4.70/3.37. The difference between the
firmware sets is that the 3.37 firmware supports ``round robin''
The Buslogic cards also have a serial number on them. If you
have a old hardware revision card you can call the Buslogic RMA
department and give them the serial number and attempt to
exchange the card for a newer hardware revision. If the card is
young enough they will do so.
FreeBSD 2.1 only supports Firmware revisions 2.21 onward. If you
have a Firmware revision older than this your card will not be
recognized as a Buslogic card. It may be recognized as an
Adaptec 1540, however. The early Buslogic firmware contains an
AHA1540 ``emulation'' mode. This is not a good thing for an EISA
card, however.
If yu have an old hardware revision card and you obtain the 2.21
firmware for it, you will need to check the position of jumper W1
to B-C, the default is A-B.
The 742a EISA cards never had the ``> 16MB'' problem mentioned in
the section <ref id="bigram" name="on 32 MB machines">. This is a
problem that occurs with the Vesa-Local Buslogic SCSI cards.

these companies every measure of success, and can only hope that

<p>
First, get the XFree86(tm) distribution of X11R6 from

later is <tt/XFree86 3.1.1/. Follow the instructions for

<heading>I've been trying to run ghostscript on a 386 (or 486sx) with no math co-processor and I keep getting errors. What's up?<label id="emul"></heading>
<p>
You will need to add the alternate math emulator to your kernel,
you do this by adding the following to your kernel config file
and it will be compiled in.
<verb>
options GPL_MATH_EMULATE
</verb>
<bf/NOTE/ You will need to remove the <tt/MATH&lowbar;EMULATE/
option when you do this.
<sect1>
<heading>I want all this neat software, but I haven't got the space or CPU power to compile it all myself. Is there any way of getting binaries?</heading>
<p>
Yes. We support the concept of a ``package'', which is
essentially a gzipped binary distribution with a little extra
intelligence embedded in it for doing any custom installation
work required. Packages can also be installed or uninstalled
again easily without having to know the gory details. CDROM
people will have a <tt>packages/</tt> directory on their CD,
others can get the currently available packages from:
<url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/packages"
name="FreeBSD's packages">
Note that all ports may not be available as packages, and that
new packages are constantly being added. It is always a good
idea to check periodically to see which packages are available.
A <tt/README/ file in the packages directory provides more
details on the care and feeding of the package software, so no
explicit details will be given here.
<sect1>
<heading>I'm trying to get a SCO/iBCS2 application to run, it keeps bombing about <tt/socksys/. How do I set this up ?</heading>
<p>
You first need to edit the <tt>/etc/sysconfig</tt> in the last
section to change the following variable to <tt/YES/:
<code>
# Set to YES if you want ibcs2 (SCO) emulation loaded at startup
ibcs2=NO
</code>
It will load the <tt/ibcs2/ kernel module at startup.
You'll then need to set up /compat/ibcs2/dev to look like:
<code>
lrwxr-xr-x 1 root wheel 9 Oct 15 22:20 X0R@ -> /dev/null
lrwxr-xr-x 1 root wheel 7 Oct 15 22:20 nfsd@ -> socksys
-rw-rw-r-- 1 root wheel 0 Oct 28 12:02 null
lrwxr-xr-x 1 root wheel 9 Oct 15 22:20 socksys@ -> /dev/null
crw-rw-rw- 1 root wheel 41, 1 Oct 15 22:14 spx
</code>
You just need socksys to go to <tt>/dev/null</tt> to fake the
open &amp; close. The code in -current will handle the rest.
This is much cleaner than the way it was done before. If you
want the <tt/spx/ driver for a local socket X connection, define
<tt/SPX&lowbar;HACK/ when you compile the system.
<sect>
<heading>Miscellaneous Questions</heading>
<p>
<sect1>
<heading>Why does FreeBSD consume far more swap space than Linux?</heading>
<p>
It doesn't. You might mean ``why does my swap seem full?''. If
that is what you really meant, it's because putting stuff in swap
rather than discarding it makes it faster to recover than if the
pager had to go through the file system to pull in clean
(unmodified) blocks from an executable.
The actual amount of dirty pages that you can have in core at
once is not reduced; the clean pages are displaced as necessary.
<sect1>
<heading>Hey! Chmod doesn't change the file permissions of symlinked files! What's going on?</heading>
<p>
You have to use either ``<tt/-H/'' or ``<tt/-L/'' together with
the ``<tt/-R/'' option to make this work. See the <tt/chmod(1)/
and <tt/symlink(7)/ man pages for more info.
<bf/WARNING/ the ``<tt/-R/'' option does a <bf/RECURSIVE/
<tt/chmod/. Be careful about specifying directories or symlinks
to directories to <tt/chmod/. If you want to change the
permissions of a directory referenced by a symlink, use
<tt/chmod(1)/ without any options and follow the symlink with a
trailing slash (``<tt>/</tt>''). For example, if ``<tt/foo/'' is
a symlink to directory ``<tt/bar/'', and you want to change the
permissions of ``<tt/foo/'' (actually ``<tt/bar/''), you would do
something like:
<verb>
chmod 555 foo/
</verb>
With the trailing slash, <tt/chmod/ will follow the symlink,
``<tt/foo/'', to change the permissions of the directory,
``<tt/bar/''.
<sect1>
<heading>How do I mount a CDROM? I've tried using <tt/mount(8)/, but it keeps on giving me an error like, ``<tt>/dev/cd0a on /mnt: Incorrect super block.</tt>''</heading>
<p>
You have to tell <tt/mount(8)/ the type of the device that you
want to mount. By default, <tt/mount(8)/ will assume the
filesystem is of type ``<tt/ufs/''. You want to mount a CDROM
filesystem, and you do this by specifying the ``<tt/-t cd9660/''
option to <tt/mount(8)/. This does, of course, assume that the
CDROM contains an ISO 9660 filesystem, which is what most CDROMs
have. As of 1.1R, FreeBSD also understands the Rock Ridge
(long filename) extensions.
As an example, if you want to mount the CDROM device,
``<tt>/dev/cd0c</tt>'', under <tt>/mnt</tt>, you would execute:
<verb>
mount -t cd9660 /dev/cd0c /mnt
</verb>
Note that your device name (``<tt>/dev/cd0c</tt>'' in this
example) could be different, depending on the CDROM interface.
Note that the ``<tt/-t cd9660/'' option just causes the
``<tt/mount&lowbar;cd9660/'' command to be executed, and so the
above example could be shortened to:
<verb>
mount_cd9660 /dev/cd0c /mnt
</verb>
<sect1>
<heading>When I try to mount a CDROM, I get a ``Device not configured'' error. What's going on?</heading>
<p>
This generally means that there is no CDROM in the CDROM drive.
Feed the drive something.
<sect1>
<heading>My programs occasionally die with ``Signal 11'' errors. What's going on?</heading>
<p>
This can be caused by bad hardware (memory, motherboard, etc.).
Try running a memory-testing program on your PC. Note that, even
though every memory testing program you try will report your
memory as being fine, it's possible for slightly marginal memory
to pass all memory tests, yet fail under operating conditions
(such as during busmastering DMA from a SCSI controller like the
Adaptec 1542).

<heading>Help, some of my X Window menus and dialog boxes don't work right! I can't select them.</heading>

the following line in the ``<tt/Keyboard/'' section of the

# when using pre-R6 clients

<heading>When I boot FreeBSD with my ATI Mach 64 videocard the following happens: when the system probes the hardware during boot the screen goes black and synchronization is lost and I'm not even using X! What's the problem?!</heading>
<p>
The problem is that the ATI Mach 64 uses address <tt/2e8/, and
the fourth serial port does too. Due to a bug (feature?) in the
sio.c driver it will touch this port even if you don't have the
fourth serial port, and <bf/even/ if you disable sio3 (the fourth
port) which normally uses this address.
<sect1>
<heading>What's the solution or workaround for this problem?</heading>
<p>
Until the bug has been fixed, you can use this workaround:
<enum>
<item> Enter <tt/-c/ at the bootprompt. <newline>
&lsqb; the kernel goes into configuration mode &rsqb;
<item> Disable <tt/sio0/, <tt/sio1/, <tt/sio2/ and <tt/sio3/
(all of them). This way the sio driver doesn't get activated
-> no problems.
<item> Type exit to continue booting.
</enum>
<sect1>
<heading>The workaround works fine, but now I want to use my serial ports.</heading>
<p>
You'll have to build a new kernel with the following
modification: in <tt>/usr/src/sys/i386/isa/sio.c</tt> find the
one occurrence of the string <tt/0x2e8/ and remove that string
and the preceding comma (keep the trailing comma). Now follow
the normal procedure of building a new kernel.
<sect1>
<heading>Now everything runs great, except for X Window: my screen goed black or X Window runs but with all kinds of problems.</heading>
<p>
Some newer ATI Mach 64 video cards (notably ATI Mach Xpression)
do not run with the current version of <tt/XFree86/. You can get
a beta-version of a new X-server that works better, by looking at
<url url="http://www.xfree86.org" name="the XFree86 site">
and following the links to the new beta release. Get the
following files:
<tt>AccelCards, BetaReport, Cards, Devices, FILES, README.ati,
README.FreeBSD, README.Mach64, RELNOTES, VGADriver.Doc,
X312BMa64.tgz</tt>
Replace the older files with the new versions and make sure you
run <tt/xf86config/ again.
<sect1>
<heading>How do I access the virtual consoles?</heading>
<p>
If the console is not currently displaying X Window, just press
Alt-F1 to Alt-F12.
<bf/NOTE/ the default FreeBSD installation has
only three (3) virtual consoles enabled, and so only Alt-F1,
Alt-F2, and Alt-F3 will work to switch between three virtual
consoles. If you want to increase this number, see the next
question.
If the console is currently displaying X Window, you can use
Ctrl-Alt-F1, etc. to switch to a virtual console. Note, however,
that once you've switched away from X Window to a virtual
terminal, you use only the Alt- function key to switch to another
virtual terminal or back to X Window. You do not also press the
Ctrl key; the Ctrl-Alt-function key combination is used only when
switching from X Window to a virtual terminal.
<sect1>
<heading>How do I increase the number of virtual consoles?</heading>
<p>
Edit <tt>/etc/ttys</tt> and add entries for ``<tt/ttyv4/'' to
``<tt/ttyvc/'' after the comment on ``Virtual terminals'' (delete
the leading whitespace in the following example):
<verb>
# Edit the existing entry for ttyv3 in /etc/ttys and change
# "off" to "on".
ttyv3 "/usr/libexec/getty Pc" cons25 on secure
ttyv4 "/usr/libexec/getty Pc" cons25 on secure
ttyv5 "/usr/libexec/getty Pc" cons25 on secure
ttyv6 "/usr/libexec/getty Pc" cons25 on secure
ttyv7 "/usr/libexec/getty Pc" cons25 on secure
ttyv8 "/usr/libexec/getty Pc" cons25 on secure
ttyv9 "/usr/libexec/getty Pc" cons25 on secure
ttyva "/usr/libexec/getty Pc" cons25 on secure
ttyvb "/usr/libexec/getty Pc" cons25 on secure
</verb>
Use as many or as few as you want. The more virtual terminals
you have, the more resources that are used; this can be important
if you have 8MB RAM or less. You may also want to change the
``<tt/secure/'' to ``<tt/insecure/''.
<bf/IMPORTANT NOTE/ if you want to run X Window, you <bf/MUST/
leave a virtual terminal unused (or turned off). For example, if
you want to attach a virtual terminal to all of your twelve
Alt-function keys, you can only attach virtual terminals to
eleven of them. The last must be left unused, because X Windows
will use it, and you will use the last Alt-function key to switch
back to X Window (after you have switched from X Window to a
virtual console via a Ctrl-Alt-function key). The easiest way to
do this is to disable a console by turning it off. For example,
if you have a keyboard with twelve function keys, you would
change settings for virtual terminal 12 from:
<verb>
ttyvb "/usr/libexec/getty Pc" cons25 on secure
</verb>
to:
<verb>
ttyvb "/usr/libexec/getty Pc" cons25 off secure
</verb>
If your keyboard has only ten function keys, you would end up with:
<verb>
ttyv9 "/usr/libexec/getty Pc" cons25 off secure
ttyva "/usr/libexec/getty Pc" cons25 off secure
ttyvb "/usr/libexec/getty Pc" cons25 off secure
</verb>
(You could also just delete these lines.)
Once you have edited <tt>/etc/ttys</tt>, the next step is to make
sure that you have enough virtual terminal devices. The easiest
way to do this is:
<verb>
cd /dev
./MAKEDEV vty12 # For 12 devices
</verb>
Next, the easiest (and cleanest) way to activate the virtual
consoles is to reboot. However, if you really don't want to
reboot, you can just shut down X Window and execute (as
<tt/root/):
<verb>
kill -HUP 1
</verb>
It's imperative that you completely shut down X Window if it is
running, before running this command. If you don't, your system
will probably appear to hang/lock up after executing the kill
command.
<sect1>
<heading>How do I start XDM from the <tt>/etc/ttys</tt> file ?</heading>
<p>
Starting xdm via /etc/ttys is a Bad Thing. I don't know why this
crept into some README file.
Start it from your <tt/rc.local/, and be explicit about how it
has to start. If this is your last action in <tt/rc.local/, put
a ``<tt/sleep 1/'' behind, to allow <tt/xdm/ to properly
daemonize before the <tt/rc/ shell exits.
<tt/xdm/ should be started without any arguments (i.e., as a
daemon).
The Xserver config file (default:
<tt>/usr/X11R6/lib/X11/xdm/Xservers</tt>) should contain the
line:
<code>
:0 local /usr/X11R6/bin/X :0 vt08 -wm
</code>
Of course, you can omit the ``<tt/-wm/'' if you don't like it,
but the `<tt/`vt08/'' is quite important -- it must point to a vt
that won't be used by <tt/getty/'s about a second later.

<heading>What is this thing called ``<tt/sup/'', and how do I use it?</heading>
<p>
SUP stands for Software Update Protocol, and was developed by CMU
for keeping their development trees in sync. We use it to keep
remote sites in sync with our central development sources.
Unless you have direct Internet connectivity, and don't care too
much about the cost/duration of the sessions, you shouldn't use
sup. For those ``low/expensive-bandwidth'' applications, we have
developed <tt/CTM/, see the section <ref id="ctm" name="on CTM">
for more about that.
To use it, you need to have direct Internet connectivity (not
just mail or news). First, pick up the <tt/sup.tgz/ package
from:
<url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/packages/sup.tgz"
name="The SUP package">
Second, read the <url
url="http://www.freebsd.org/How/handbook/sup.html"
name="Handbook's section on SUP">
This file describes how to setup sup on your machine. You may
also want to look at
<tt>/usr/src/share/examples/sup/*-supfile</tt>, or you may grab
updated supfiles from:

<heading>Has anyone done any temperature testing while running FreeBSD? I know Linux runs cooler than dos, but have never seen a mention of FreeBSD. It seems to run really hot</heading>
<p>
No, but we have done numerous taste tests on blindfolded
volunteers who have also had 250 micrograms of LSD-25
administered beforehand. 35% of the volunteers said that FreeBSD
tasted sort of orange, whereas Linux tasted like purple haze.
Neither group mentioned any particular variances in temperature
that I can remember. We eventually had to throw the results of
this survey out entirely anyway when we found that too many
volunteers were wandering out of the room during the tests, thus
skewing the results. I think most of the volunteers are at Apple
now, working on their new ``scratch and sniff'' GUI. It's a
funny old business we're in!
Seriously, Linux use the ``<tt/HALT/'' instruction when the
system is idle thus lowering its energy consumption and therefore
the heat it generates.
<sect1>
<heading>Is there anything "odd" that FreeBSD does when compiling the kernel which would cause the memory to make a scratchy sound? When compiling (and for a brief moment after recognizing the floppy drive upon startup, as well), a strange scratchy sound emanates from what appears to be the memory banks.</heading>
<p>
Yes! You'll see frequent references to ``daemons'' in the BSD
documentation, and what most people don't know is that this
refers to genuine, non-corporeal entities that now possess your
computer. The scratchy sound coming from your memory is actually
high-pitched whispering exchanged among the daemons as they best
decide how to deal with various system administration tasks.
If the noise gets to you, a good ``<tt>fdisk /mbr</tt>'' from DOS
will get rid of them, but don't be surprised if they react
adversely and try to stop you. In fact, if at any point during
the exercise you hear the satanic voice of Bill Gates coming from
the built-in speaker, take off running and don't ever look back!
Freed from the counterbalancing influence of the BSD daemons, the
twin demons of DOS and Windows are often able to re-assert total
control over your machine to the eternal damnation of your soul.
Given a choice, I think I'd prefer to get used to the scratchy
noises, myself!

<heading>How do I create customized installation disks that I can give out to other people at my site?</heading>
<p>
The entire process of creating installation disks and source and
binary archives is automated by various targets in
<tt>/usr/src/release/Makefile</tt>. The information there should
be enough to get you started.
<sect1>
<heading>How do I re-build my system without clobbering the existing installed binaries?</heading>
<p>
If you define the environment variable <tt/DESTDIR/ while running
``<tt/make world/'' or ``<tt/make install/'', the newly-created
binaries will be deposited in a directory tree identical to the
installed one, rooted at <tt>&dollar;&lcub;DESTDIR&rcub;</tt>.
Some random combination of shared libraries modifications and
program rebuilds can cause this to fail in ``<tt/make world/'',
however.
<sect1>
<heading>When my system booted, it told me that ``(bus speed defaulted)''. What does that mean?</heading>
<p>
The Adaptec 1542 SCSI host adapters allow the user to configure
their bus access speed in software. Previous versions of the
1542 driver tried to determine the fastest usable speed and set
the adapter to that. We found that this breaks some users'
systems, so you now have to define the ``<tt/TUNE&lowbar;1542/'' kernel
configuration option in order to have this take place. Using it
on those systems where it works may make your disks run faster,
but on those systems where it doesn't, your data could be
corrupted.
<sect1>
<heading>I would like to track changes to current and do not have net access. Is there any way besides downloading the whole tree?<label id="ctm"></heading>

<heading>How do I split up large binary files into smaller 240k files like the distribution does?</heading>

<sect>
<heading>Kernel Configuration</heading>
<p>
<sect1>
<heading>Ok, so how DO I compile my own kernel, anyway?<label id="make-kernel"></heading>
<p>
Before you can compile a kernel, you need either the complete
<tt/srcdist/ or, at the minimum, the <tt/kerndist/ loaded on your
system. This provides the necessary sources for building the
kernel, as we have a policy of <bf/NOT/ shipping our kernels in
linkable object form as most commercial UNIX vendors do.
Shipping the source takes a bit more space, but it also means
that you can refer to the actual kernel sources in case of
difficulty or to further your understanding of what's
<bf/actually/ happening.
Anyway, to answer the question, once you have the <tt/kerndist/
or <tt/srcdist/ loaded, do this:
<enum>
<item> <tt>cd /usr/src/sys/i386/conf</tt>
<item> <tt/cp GENERIC MYKERNEL/
<item> <tt/vi MYKERNEL/
<item> <tt/config MYKERNEL/
<item> <tt>cd ../../compile/MYKERNEL</tt>
<item> <tt/make depend/
<item> <tt/make all/
<item> <tt/make install/
<item> <tt/reboot/
</enum>
Step 2 may not be necessary if you already have a kernel
configuration file from a previous release of FreeBSD 2.X. -
simply bring your old one over and check it carefully for any
drivers that may have changed boot syntax or been rendered
obsolete.
A good kernel config file to look into is <tt/LINT/, which
contains entries for <bf/all/ possible kernel options and
documents them fairly well. The <tt/GENERIC/ kernel config file
is used to build the initial release you probably loaded (unless
you upgraded in-place) and contains entries for the most common
configurations. It's a pretty good place to start from.
If you don't need to make any changes to <tt/GENERIC/, you can
also skip step 3, where you customize the kernel for your
configuration. Step 7 should only be undertaken if step 6
succeeds. This will copy the new kernel image to
<tt>/kernel</tt> and <bf/BACK UP YOUR OLD ONE IN/
<tt>/kernel.old</tt>! It's very important to remember this in
case the new kernel fails to work for some reason - you can still
select <tt>/kernel.old</tt> at the boot prompt to boot the old
one. When you reboot, the new kernel will boot by default.
If the compile in 6 falls over for some reason, then it's
recommended that you start from step 4 but substitute
<tt/GENERIC/ for <tt/MYKERNEL/. If you can generate a
<tt/GENERIC/ kernel, then it's likely something in your special
configuration file that's bad (or you've uncovered a bug!). If
the build of the <tt/GENERIC/ kernel does <bf/NOT/ succeed, then
it's very likely that your sources are somehow corrupted.
Finally, if you need to see your original boot messages again to
compile a new kernel that's better tailored to your hardware, try
the <tt/dmesg(8)/ command. It should print out all the boot-time
messages printed by your old kernel, some of which may be quite
helpful in configuring the new one.
<sect1>
<heading>I don't understand, I have removed <tt/npx0/ from my kernel configuration file as I don't have a mathematic co-processor but it keeps bombing saying that <tt/&lowbar;hw&lowbar;float/ is missing.</heading>
<p>
The <tt/npx0/ is <bf/MANDATORY/. Even if you don't have a
mathematic co-processor, you <bf/must/ include the <tt/npx0/
device.
<sect1>
<heading>When I compile a kernel with multi-port serial code, it tells me that only the first port is probed and the rest skipped due to interrupt conflicts. How do I fix this?</heading>
<p>
The problem here is that FreeBSD has code built-in to keep the
kernel from getting trashed due t hardware or software
conflicts. The way to fix this is to leave out the IRQ settings
on other ports besides the first. Here is a example:
<verb>
#
# Multiport high-speed serial line - 16550 UARTS
#
device sio2 at isa? port 0x2a0 tty irq 5 flags 0x501 vector siointr
device sio3 at isa? port 0x2a8 tty flags 0x501 vector siointr
device sio4 at isa? port 0x2b0 tty flags 0x501 vector siointr
device sio5 at isa? port 0x2b8 tty flags 0x501 vector siointr
</verb>
<sect1>
<heading>FreeBSD is supposed to come with support for QIC-40/80 drives but when I look, I can't find it.</heading>
<p>
You need to uncomment the following line in the generic config
file (or add it to your config file), add a ``<tt/flags 0x1/''
on the <tt/fdc/ line and recompile.
<verb>
controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 flags 0x1 vector fdintr
disk fd0 at fdc0 drive 0 ^^^^^^^^^
disk fd1 at fdc0 drive 1
#tape ft0 at fdc0 drive 2
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
</verb>
Next, you create a device called <tt>/dev/ft0</tt> by going into
<tt>/dev</tt> and run the following command:
<verb>
sh MAKEDEV ft0
</verb>
for the first device. <tt/ft1/ for a second one and so on.
You will have a device called <tt>/dev/ft0</tt>, which you can
write to through a special program to manage it called
``<tt/ft/'' - see the man page on <tt/ft/ for further details.
Versions previous to <tt/-current/ also had some trouble dealing
with bad tape media; if you have trouble where <tt/ft/ seems to
go back and forth over the same spot, try grabbing the latest
version of <tt/ft/ from <tt>/usr/src/sbin/ft</tt> in
<tt/-current/ and try that.
<sect1>
<heading>Does FreeBSD support IPC primitives like those in System V?</heading>
<p>
Yes, FreeBSD supports System V-style IPC. This includes shared
memory, messages and semaphores. You need to add the following
lines to your kernel config to enable them.
<verb>
options SYSVSHM
options "SHMMAXPGS=64" # 256Kb of sharable memory
options SYSVSEM # enable for semaphores
options SYSVMSG # enable for messaging
</verb>
Recompile and install.
<sect1>
<heading>I have 128 MB of RAM but it seems that the system use only the first 64 MB. What's going on ?</heading>
<p>
Due to the manner in which FreeBSD gets the memory size from the
BIOS, it can only detect 16 bits worth of Kbytes in size (65535
Kbytes = 64MB). If you have more than 64MB, FreeBSD will only see
the first 64MB. To work around this problem, you need to use the
kernel option specified below. There is a way to get complete
memory information from the BIOS, but we don't have room in the
bootblocks to do it. Someday when lack of room in the bootblocks
is fixed, we'll use the extended BIOS functions to get the full
memory information...but for now we're stuck with the kernel
option.
<code>
options "MAXMEM=<n>"
</code>
Where <tt/n/ is your memory in Kilobytes. For a 128 MB machine,
you'd want to use <tt/131072/
<sect1>
<heading>Sometimes my FreeBSD 2.0 reboots saying: ``Panic: kmem_map (or mb_map) too small !''.
<p>
The panic indicates that the system ran out of virtual memory for
network buffers (specifically, mbuf clusters). You can increase
the amount of VM available for mbuf clusters by adding:
<code>
options "NMBCLUSTERS=<n>"
</code>
to your kernel config file, where &lt;n&gt; is a number in the
range 512-4096, depending on the number of concurrent TCP
connections you need to support. I'd recommend trying 2048 - this
should get rid of the panic completely. You can monitor the
number of mbuf clusters allocated/in use on the system with
<tt/netstat -m/.
<sect1>

<heading>System Administration</heading>
<sect1>
<heading>Hmm, where are my familiar BSD system files ? What's this <tt>/etc/sysconfig</tt> thing?</heading>
<p>
As for 2.0.5R, the primary configuration file is
<tt>/etc/sysconfig</tt>. All the options are to be specified in
this one and the other one (<tt>/etc/rc</tt> and
<tt>/etc/netstart</tt>) just include it.
Look in the <tt>/etc/sysconfig</tt> file and change the value to
match your system. This file is filled with comments to show what
to put in there.
The <tt>/etc/rc.local</tt> is here as always and is the place to
put additional services like <tt/INN/ or a <tt/http/ server.
The <tt>/etc/rc.serial</tt> is for serial port initialization
(e.g. locking the port characteristics, and so on.).
The <tt>/etc/rc.i386</tt> is for Intel-specifics setting like the
iBCS2 emulation.
Starting with 2.1.0R, you can have "local" startup files in a
directory specified in <tt>/etc/sysconfig</tt>:
<verb>
# Location of local startup files.
local_startup=/usr/local/etc/rc.local.d
</verb>
Each file ending in <tt/.sh/ will be executed in alphabetic
order.
If you want to have a proper order without changing all the file
names, you can use a scheme similar to the following with digits
prepended to each file name to insure order:
<verb>
10news.sh
15httpd.sh
20ssh.sh
</verb>
It can be seen as ugly (or SysV :-)) but it provides a simple and
regular scheme for locally-added packages without resorting to
magical editing of <tt>/etc/rc.local</tt>.

providing packet forwarding by default in FreeBSD. You can
however enable this feature by changing the following variable to
<tt/YES/ in <tt>/etc/sysconfig</tt>:
<verb>
# If you want this host to be a gateway, set to YES.
gateway=YES
</verb>
This option will put the <tt/sysctl/ variable
<tt/net.inet.ip.forwarding/ to <tt/1/.
In most cases, you will also need to run a routing process to
tell other systems on your network about your router; FreeBSD
comes with the standard BSD routing daemon <tt/routed(8)/, or for
more complex situations you may want to try <em/GaTeD/ (available
by FTP from <tt/ftp.gated.Merit.EDU/) which supports FreeBSD as
of 3_5Alpha7.
It is our duty to warn you that, even when FreeBSD is configured
in this way, it does not completely comply with the Internet
standard requirements for routers; however, it comes close enough
for ordinary usage.
<sect1>
<heading>Does FreeBSD support SLIP and PPP?</heading>
<p>
Yes. See the man pages for <tt/slattach(8)/ and/or <tt/pppd(8)/
if you're using FreeBSD to connect to another site. If you're
using FreeBSD as a server for other machines, look at the man
page for <tt/sliplogin(8)/.
You can also have a look at the SLIP/PPP/Use PPP sections of the
handbook in <tt>/usr/share/doc/handbook</tt> or use the following

<heading>I've got problems with my IJPPP, I connect and it goes to PPP mode but I can't get out! Whats up?</heading>
<p>
One problem we have had reported is IJPPPs' use of predictor1
compression. One way of determining if you have this problem
is to look at your log and if you have protocol errors then this is
most likely it.
These can be shut off with:
<verb>
deny pred1
disable pred1
</verb>
Use these two before you dial out and it should work.

<heading>How do I get my network set up? I don't see how to make my <tt>/dev/ed0</tt> device!</heading>
<p>
In the Berkeley networking framework, network interfaces are only
directly accessible by kernel code. Please see the
<tt>/etc/netstart</tt> file and the manual pages for the various
network programs mentioned there for more information. If this
leaves you totally confused, then you should pick up a book
describing network administration on another BSD-related
operating system; with few significant exceptions, administering
networking on FreeBSD is basically the same as on SunOS 4.0 or
Ultrix.
<sect1>
<heading>How can I setup Ethernet aliases ? It always says: ``File exists''.</heading>
<p>
Add ``<tt/netmask 0xffffffff/'' to your <tt/ifconfig/
command-line like the following:
<verb>
ifconfig ed0 alias 204.141.95.2 netmask 0xffffffff
</verb>
<sect1>
<heading>How do I get my 3C503 to use the other network port?</heading>
<p>
If you want to use the other ports, you'll have to specify an
additional parameter on the <tt/ifconfig(1)/ command line. The
default port is ``<tt/link0/''. To use the AUI port instead of
the BNC one, use ``<tt/link2/''.

<heading>I'm having problems with NFS to/from FreeBSD and my Wuffotronics Workstation / generic NFS appliance, where should I look first?</heading>

applications like NFS.

<heading>I want to enable IP multicast support on my FreeBSD box, how do I do it? (Alternatively: What the heck IS multicasting and what applications make use of it?)</heading>
<p>
Multicast host operations are fully supported in FreeBSD 2.0 by
default. If you want your box to run as a multicast router, you
will need to load the <tt/ip_mroute_mod/ loadable kernel module
and run <tt/mrouted/.

<heading>I'm in <tt>foo.bar.edu</tt>, and I can no longer reach hosts in <tt>bar.edu</tt> by their short names</heading>
<p>
The current version of <em>BIND</em> that ships with FreeBSD
does no longer provide default abbreviations for non-fully
qualified domain names other than the domain you are in.
So an unqualified host <tt>mumble</tt> must either be found
as <tt>mumble.foo.bar.edu</tt>, or it will be searched for
in the root domain.
<p>
This is different from the previous behaviour, where the
search did continue across <tt>mumble.bar.edu</tt>, and
<tt>mumble.edu</tt>. Have a look at RFC 1535 for why this
has been considered bad practice and even a security hole.
<p>
As a good workaround, you can place the line
<p><tt>
search foo.bar.edu bar.edu
</tt><p>
instead of the previous
<p><tt>
domain foo.bar.edu
</tt><p>
into your <tt>/etc/resolv.conf</tt>. However, make sure
that the search order does not go beyond the ``boundary
between local and public administration'', as RFC 1535
calls ist.
</sect1>
<sect1>
<heading>Now that I've got all through my UUCP setup, how do I convince sendmail to use it for mail delivery?</heading>
<p>
The sendmail configuration that ships with FreeBSD is
suited for sites that connect directly to the Internet.
Sites that wish to exchange their mail via UUCP must install
another sendmail configuration file.
<p>
Tweaking <tt>/etc/sendmail.cf</tt> manually is considered
something for purists. Sendmail version 8 comes with a
new approach of generating config files via some <tt>m4</tt>
preprocessing, where the actual hand-crafted configuration
is on a higher abstraction level. You should use the
configuration files under
<verb>
/usr/src/usr.sbin/sendmail/cf
</verb>
If you don't have installed your system with full sources,
this won't be a problem. The sendmail config stuff has been
broken out into a separate source distribution tarball just
for you. Assuming you've got your CD-ROM mounted, do:
<verb>
cd /usr/src
tar -xvzf /cdrom/dists/src/ssmailcf.aa
</verb>
Don't bother, this is only a few hundred kilobytes in size.
The file <tt>README</tt> in the <tt>cf</tt> directory can
serve as a basic introduction into the m4 configuration.
<p>
For UUCP delivery, you will go best by using the
<em>mailertable</em> feature. This constitutes a database
that sendmail can use to base its routing decision upon.
<p>
First, you have to create your <tt>.mc</tt> file. The
directory <tt>/usr/src/usr.sbin/sendmail/cf/cf</tt> is the
home of these files. Look around, there are already a few
examples. Assuming you have named your file <tt>foo.mc</tt>,
all you need to do in order to convert it into a valid
<tt>sendmail.cf</tt> is:
<verb>
cd /usr/src/usr.sbin/sendmail/cf/cf
make foo.cf
cp foo.cf /etc/sendmail.cf
</verb>
A typical <tt>.mc</tt> file might look like:
<verb>
include(`../m4/cf.m4')
VERSIONID(`Your version number')
OSTYPE(bsd4.4)
FEATURE(nodns)
FEATURE(nocanonify)
FEATURE(mailertable)
define(`UUCP_RELAY', your.uucp.relay)
define(`UUCP_MAX_SIZE', 200000)
MAILER(local)
MAILER(smtp)
MAILER(uucp)
Cw your.alias.host.name
Cw youruucpnodename.UUCP
</verb>
The <em>nodns</em> and <em>nocanonify</em> features will
prevent any usage of the DNS during mail delivery. The
<em>UUCP_RELAY</em> clause is needed for bizarre reasons,
don't ask. Simply put an Internet hostname there that
is able to handle .UUCP pseudo-domain addresses; most likely,
you will enter the mail relay of your ISP there.
<p>
Once you've got this, you need this file called
<tt>/etc/mailertable</tt>. A typical example of this
gender again:
<verb>
#
# makemap hash /etc/mailertable.db < /etc/mailertable
#
horus.interface-business.de uucp-dom:horus
.interface-business.de uucp-dom:if-bus
interface-business.de uucp-dom:if-bus
.heep.sax.de smtp8:%1
horus.UUCP uucp-dom:horus
if-bus.UUCP uucp-dom:if-bus
. uucp-dom:sax
</verb>
As you can see, this is part of a real-life file. The first
three lines handle special cases where domain-addressed mail
should not be sent out to the default route, but instead to
some UUCP neighbour in order to ``shortcut'' the delivery
path. The next line handles mail to the local Ethernet
domain that can be delivered using SMTP. Finally, the UUCP
neighbours are mentioned in the .UUCP pseudo-domain notation,
to allow for a ``uucp-neighbour!recipient'' override of the
default rules. The last line is always a single dot, matching
everything else, with UUCP delivery to a UUCP neighbour that
serves as your universal mail gateway to the world. All of
the node names behind the <tt>uucp-dom:</tt> keyword must
be valid UUCP neighbours, as you could verify using the
command <tt>uuname</tt>.
<p>
As a reminder that this file needs to be converted into a
DBM database file before being usable, the command line to
accomplish this is best placed as a comment at the top of
the mailertable. You always have to execute this command
each time you change your mailertable.
<p>
Final hint: if you are uncertain whether some particular
mail routing would work, remember the <tt>-bt</tt> option to
sendmail. It starts sendmail in <em>address test mode</em>,
simply enter ``0 '', followed by the address you wish to
test for the mail routing. The last line tells you the used
internal mail agent, the destination host this agent will be
called with, and the (possibly translated) address. Leave
this mode by typing Control-D.
<verb>
j@uriah 191% sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> 0 foo@interface-business.de
rewrite: ruleset 0 input: foo @ interface-business . de
...
rewrite: ruleset 0 returns: $# uucp-dom $@ if-bus $: foo \
< @ interface-business . de >

<heading>Serial Communications</heading>
<p>
This section answers common questions about serial communications
with FreeBSD.
<sect1>
<heading>How do I tell if FreeBSD found my serial ports or modem cards?</heading>
<p>
As the FreeBSD kernel boots, it will probe for the serial ports
in your system for which the kernel was configured. You can
either watch your system closely for the messages it prints or
run the command
<verb>
dmesg | grep sio
</verb>
after your system's up and running.
Here's some example output from the above command:
<verb>
sio0 at 0x3f8-0x3ff irq 4 on isa
sio0: type 16550A
sio1 at 0x2f8-0x2ff irq 3 on isa
sio1: type 16550A
</verb>
This shows two serial ports. The first is on irq 4, is using
port address <tt/0x3f8/, and has a 16550A-type UART chip. The
second uses the same kind of chip but is on irq 3 and is at port
address <tt/0x2f8/. Internal modem cards are treated just like
serial ports---except that they always have a modem ``attached''
to the port.
The <tt/GENERIC/ kernel includes support for two serial ports
using the same irq and port address settings in the above
example. If these settings aren't right for your system, or if
you've added modem cards or have more serial ports than your
kernel is configured for, just reconfigure your kernel. See
section <ref id="make-kernel" name="about building a kernel"> for
more details.
<sect1>
<heading>Hey, I just upgraded to 2.0.5 and my <tt/tty0X/ are missing!</heading>
<p>
Don't worry, they have been merged with the <tt/ttydX/
devices. You'll have to change old configuration files.
<sect1>
<heading>How do I access the serial ports once FreeBSD is running?</heading>
<p>
The third serial port, <tt/sio2/ (known as COM3 in DOS), is on
<tt>/dev/cuaa2</tt> for dial-out devices, and on
<tt>/dev/ttyd2</tt> for dial-in devices. What's the difference
between these two classes of devices?
You use <tt/ttydX/ for dial-ins. When opening
<tt>/dev/ttydX</tt> in blocking mode, a process will wait for the
corresponding <tt/cuaaX/ device to become inactive, and then wait
for the carrier detect line to go active. When you open the
<tt/cuaaX/ device, it makes sure the serial port isn't already in
use by the <tt/ttydX/ device. If the port's available, it
``steals'' it from the <tt/ttydX/ device. Also, the <tt/cuaXX/
device doesn't care about carrier detect. With this scheme and
an auto-answer modem, you can have remote users log in and you
can still dialout with the same modem and the system will take
care of all the conflicts.
<sect1>
<heading>How do I configure the kernel for my multiport serial card?</heading>
<p>
Again, the section on kernel configuration provides information
about configuring your kernel. For a multiport serial card,
place an <tt/sio/ line for each serial port on the card in the
kernel configuration file. But place the irq and vector
specifiers on only one of the entries. All of the ports on the
card should share one irq. For consistency, use the last serial
port to specify the irq. Also, specify the
<tt/COM&lowbar;MULTIPORT/ option.
The following example is for an AST 4-port serial card on irq 7:
<verb>
options "COM_MULTIPORT"
device sio4 at isa? port 0x2a0 tty flags 0x781
device sio5 at isa? port 0x2a8 tty flags 0x781
device sio6 at isa? port 0x2b0 tty flags 0x781
device sio7 at isa? port 0x2b8 tty flags 0x781 irq 7 vector siointr
</verb>
The flags indicate that the master port has minor number 7
(<tt/0x700/), diagnostics enabled during probe (<tt/0x080/), and
all the ports share an irq (<tt/0x001/).
<sect1>
<heading>I have two multiport serial cards that can share irqs. Can FreeBSD handle this?</heading>
<p>
Not yet. You'll have to use a different irq for each card.
<sect1>
<heading>What's the difference between <tt/ttyd1/, <tt/ttyid1/, and <tt/ttyld1/? Or, how can I set the default serial parameters for a port?</heading>
<p>
The <tt/ttydX/ (or <tt/cuaaX/) device is the regular device
you'll want to open for your applications. When a process opens
the device, it'll have a default set of terminal I/O settings.
You can see these settings with the command
<verb>
stty -a -f /dev/ttyd1
</verb>
When you change the settings to this device, the settings are in
effect until the device is closed. When it's reopened, it goes
back to the default set. To make changes to the default set, you
can open and adjust the settings of the ``initial state'' device.
For example, to turn on <tt/CLOCAL/ mode, 8 bits, and
<tt>XON/XOFF</tt> flow control by default for ttyd5, do:
<verb>
stty -f /dev/ttyid5 clocal cs8 ixon ixoff
</verb>
A good place to do this is in <tt>/etc/rc.serial</tt>. Now, an
application will have these settings by default when it opens
<tt/ttyd5/. It can still change these settings to its liking,
though.
You can also prevent certain settings from being changed by an
application by making adjustments to the ``lock state'' device.
For example, to lock the speed of <tt/ttyd5/ to 57600 bps, do
<verb>
stty -f /dev/ttyld5 57600
</verb>
Now, an application that opens <tt/ttyd5/ and tries to change the
speed of the port will be stuck with 57600 bps.
Naturally, you should make the initial state and lock state
devices writable only by <tt/root/. The <tt/MAKEDEV/ script does
<bf/NOT/ do this when it creates the device entries.
<sect1>
<heading>How can I enable dialup logins on my modem?</heading>
<p>
So you want to become an Internet service provider, eh? First,
you'll need one or more modems that can auto-answer. Your modem
will need to assert carrier-detect when it detects a carrier and
not assert it all the time. It will need to hang up the phone
and reset itself when the data terminal ready (<tt/DTR/) line
goes from on to off. It should probably use <tt>RTS/CTS</tt>
flow control or no local flow control at all. Finally, it must
use a constant speed between the computer and itself, but (to be
nice to your callers) it should negotiate a speed between itself
and the remote modem.
For many Hayes command-set--compatible modems, this command will
make these settings and store them in nonvolatile memory:
<verb>
AT &ero;C1 &ero;D3 &ero;K3 &ero;Q6 S0=1 &ero;W
</verb>
See the section <ref id="direct-at" name="on sending AT
commands"> below for information on how to make these settings
without resorting to an MS-DOS terminal program.
Next, make an entry in <tt>/etc/ttys</tt> for the modem. This
file lists all the ports on which the operating system will await
logins. Add a line that looks something like this:
<verb>
ttyd1 "/usr/libexec/getty std.57600" dialup on insecure
</verb>
This line indicates that the second serial port
(<tt>/dev/ttyd1</tt>) has a modem connected running at 57600 bps
and no parity (<tt/std.57600/, which comes from the file
<tt>/etc/gettytab</tt>). The terminal type for this port is
``dialup.'' The port is ``on'' and is ``insecure''---meaning
root logins on the port aren't allowed. For dialin ports like
this one, use the <tt/ttydX/ entry.
It's common practice to use ``dialup'' as the terminal type.
Many users set up in their .profile or .login files a prompt for
the actual terminal type if the starting type is dialup. The
example shows the port as insecure. To become root on this port,
you have to login as a regular user, then ``<tt/su/'' to
<tt/root/. If you use ``secure'' then <tt/root/ can login in
directly.
After making modifications to <tt>/etc/ttys</tt>, you need to
send a hangup or <tt/HUP/ signal to the <tt/init/ process:
<verb>
kill -1 1
</verb>
This forces the init process to reread <tt>/etc/ttys</tt>. The
init process will then start getty processes on all ``on'' ports.
You can find out if logins are available for your port by typing
<verb>
ps -ax | grep '[t]tyd1'
</verb>
You should see something like:
<verb>
747 ?? I 0:00.04 /usr/libexec/getty std.57600 ttyd1
</verb>
<sect1>
<heading>How can I make my spare computer a dumb terminal connected to my FreeBSD box?</heading>
<p>
If you're using another computer as a terminal into your FreeBSD
system, get a null modem cable to go between the two serial
ports. If you're using an actual terminal, see its accompanying
instructions.
Then, modify <tt>/etc/ttys</tt>, like above. For example, if
you're hooking up a WYSE-50 terminal to the fifth serial port,
use an entry like this:
<verb>
ttyd4 "/usr/libexec/getty std.38400" wyse50 on secure
</verb>
This example shows that the port on <tt>/dev/ttyd4</tt> has a
wyse50 terminal connected at 38400 bps with no parity
(<tt/std.38400/ from <tt>/etc/gettytab</tt>) and <tt/root/ logins
are allowed (secure).
<sect1>
<heading>Why can't I run <tt/tip/ or <tt/cu/?</heading>
<p>
On your system, the programs <tt/tip/ and <tt/cu/ are probably
executable only by <tt/uucp/ and group <tt/dialer/. You can use
the group <tt/dialer/ to control who has access to your modem or
remote systems. Just add yourself to group dialer.
Alternatively, you can let everyone on your system run <tt/tip/
and <tt/cu/ by typing:
<verb>
chmod 4511 /usr/bin/tip
</verb>
You don't have to run this command for <tt/cu/, since <tt/cu/ is
just a hard link to <tt/tip/.
<sect1>
<heading>My stock Hayes modem isn't supported---what should I do?</heading>
<p>
Actually, the man page for <tt/tip/ is out of date. There is a
generic Hayes dialer already built in. Just use
``<tt/at=hayes/'' in your <tt>/etc/remote</tt> file.
The Hayes driver isn't smart enough to recognize some of the
advanced features of newer modems---messages like <tt/BUSY/,
<tt/NO DIALTONE/, or <tt/CONNECT 115200/ will just confuse it.
You should turn those messages off when you use <tt/tip/ (using
<tt/ATX0&amp;W/).
Also, the dial timeout for <tt/tip/ is 60 seconds. Your modem
should use something less, or else tip will think there's a
communication problem. Try <tt/ATS7=45&amp;W/.
Actually, as shipped <tt/tip/ doesn't yet support it fully. The
solution is to edit the file <tt/tipconf.h/ in the directory
<tt>/usr/src/usr.bin/tip/tip</tt> Obviously you need the source
distribution to do this.
Edit the line ``<tt/#define HAYES 0/'' to ``<tt/#define HAYES
1/''. Then ``<tt/make/'' and ``<tt/make install/''. Everything
works nicely after that.
<sect1>
<heading>How am I expected to enter these AT commands without resorting to some DOS-based terminal program?<label id="direct-at"></heading>
<p>
Make what's called a ``<tt/direct/'' entry in your
<tt>/etc/remote</tt> file. For example, if your modem's hooked
up to the first serial port, <tt>/dev/cuaa0</tt>, then put in the
following line:
<verb>
cuaa0:dv=/dev/cuaa0:br#19200:pa=none
</verb>
Use the highest bps rate your modem supports in the br
capability. Then, type ``<tt/tip cuaa0/'' and you'll be
connected to your modem.
If there is no <tt>/dev/cuaa0</tt> on your system, do this:
<verb>
cd /dev
MAKEDEV cuaa0
</verb>
<p>
Or use cu as root with the following command:
<verb>
cu -l``line'' -s``speed''
</verb>
with line being the serial port (e.g.<tt>/dev/cuaa0</tt>)
and speed being the speed (e.g.<tt>57600</tt>).
When you done entering the AT commands hit <tt>~.</tt> to exit.
<sect1>
<heading>Why doesn't the <tt/@/ sign for the phone number capability work?</heading>
<p>
The <tt/@/ sign in the pn capability tells tip to look in
<tt>/etc/phones</tt> for a phone number. But the <tt/@/ sign is
also a special character in capability files like
<tt>/etc/remote</tt>. Escape it with a backslash:
<verb>
pn=\@
</verb>
<sect1>
<heading>How can I dial a phone number on the command line?</heading>
<p>
Put what's called a ``<tt/generic/'' entry in your
<tt>/etc/remote</tt> file. For example:
<verb>
tip115200|Dial any phone number at 115200 bps:\
:dv=/dev/cuaa0:br#115200:at=hayes:pa=none:du:
tip57600|Dial any phone number at 57600 bps:\
:dv=/dev/cuaa0:br#57600:at=hayes:pa=none:du:
</verb>
Then you can things like ``<tt/tip -115200 5551234/''. If you
prefer <tt/cu/ over <tt/tip/, use a generic cu entry:
<verb>
cu115200|Use cu to dial any number at 115200bps:\
:dv=/dev/cuaa1:br#57600:at=hayes:pa=none:du:
</verb>
and type ``<tt/cu 5551234 -s 115200/''.
<sect1>
<heading>Great---but how can I do that without having to specify the bps rate on the command line?</heading>
<p>
Put in an entry for <tt/tip1200/ or <tt/cu1200/, but go ahead and
use whatever bps rate is appropriate with the br
capability. <tt/tip/ thinks a good default is 1200 bps which is
why it looks for a ``<tt/tip1200/'' entry. You don't have to use
1200 bps, though.
<sect1>
<heading>I want separate entries for various hosts I access through a terminal server, but I don't want to type ``<tt/CONNECT &lt;host&gt;/'' each time once I'm connected. Can <tt/tip/ do that for me?</heading>
<p>
Yes. Use the <tt/cm/ capability. For example, these entries in
<tt>/etc/remote</tt>:
<verb>
pain|pain.deep13.com|Forrester's machine:\
:cm=CONNECT pain\n:tc=deep13:
muffin|muffin.deep13.com|Frank's machine:\
:cm=CONNECT muffin\n:tc=deep13:
deep13:Gizmonics Institute terminal server:\
:dv=/dev/cua02:br#38400:at=hayes:du:pa=none:pn=5551234:
</verb>
will let you type ``<tt/tip pain/'' or ``<tt/tip muffin/'' to
connect to the hosts pain or muffin; and ``<tt/tip deep13/'' to
get to the terminal server.

<heading>My university has 42 billion students but only 4 modem lines. Can tip automatically try each line?</heading>
<p>
Sure. Make an entry for your university in <tt>/etc/remote</tt>
and use <tt>\@</tt> for the <tt/pn/ capability:
<verb>
big-university:\
:pn=\@:tc=dialout
dialout:\
:dv=/dev/cuaa3:br#9600:at=courier:du:pa=none:
</verb>
Then, list the phone numbers for the university in
<tt>/etc/phones</tt>:
<verb>
big-university 5551111
big-university 5551112
big-university 5551113
big-university 5551114
</verb>
<tt/tip/ will try each one in the listed order, then give up. If
you want to keep retrying, run <tt/tip/ in a while loop.
<sect1>
<heading>How come I have to hit CTRL+P twice to send CTRL+P once?</heading>
<p>
CTRL+P is the default ``force'' character, used to tell <tt/tip/
that the next character is literal data. You can set the force
character to any other character with the <tt/~s/ escape, which
means ``set a variable.''
Type ``<tt/~sforce=&lt;single-char&gt;/'' followed by a newline.
<tt/&lt;single-char&gt;/ is any single character. If you leave
out <tt/&lt;single-char&gt;/, then the force character is the nul
character, which you can get by typing CTRL+2 or CTRL+SPACE. A
pretty good value for <tt/&lt;single-char&gt;/ is SHIFT+CTRL+6,
which I've seen only used on some terminal servers.
You can have the force character be whatever you want by
specifying the following in your <tt>&dollar;HOME/.tiprc</tt>
file:
<verb>
force=<single-char>
</verb>
<sect1>
<heading>Suddenly everything I type is all UPPER CASE. What gives?</heading>
<p>
You must've pressed CTRL+A, <tt/tip/'s ``raise character,''
specially designed for people with broken caps-lock keys. Use
<tt/~s/ as above and set the variable ``raisechar'' to something
reasonable. In fact, you can set it to the same as the force
character, if you never expect to use either of these features.
Here's a sample .tiprc file perfect for Emacs users who need to
type CTRL+2 and CTRL+A a lot:
<verb>
force=^^
raisechar=^^
</verb>
The ^^ is SHIFT+CTRL+6.
<sect1>
<heading>How can I do file transfers with <tt/tip/?</heading>
<p>
If you're talking to another UNIX system, you can send and
receive files with <tt/~p/ (put) and <tt/~t/ (take). These
commands run ``<tt/cat/'' and ``<tt/echo/'' on the remote system
to accept and send files. The syntax is:
<verb>
~p <local-file> [<remote-file>]
~t <remote-file> [<local-file>]
</verb>
There's no error checking, so you probably should use another
protocol, like zmodem.
<sect1>
<heading>Okay, how can I run zmodem with <tt/tip/?</heading>
<p>
To receive files, start the sending program on the remote end.
Then, type ``<tt/~C rz/'' to begin receiving them locally.
To send files, start the receiving program on the remote end.
Then, type ``<tt/~C sz &lt;files&gt;/'' to send them to the
remote system.
