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:

|
|
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

<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

|
<heading>What do I need to run FreeBSD?</heading>
|
|
<p>
|
|
You'll need a 386 or better PC, with 4 MB 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.

<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="<doc@FreeBSD.ORG>">.

A FreeBSD ``handbook'' is being created, and can be found as:

|
|
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

A good book on system administration is:

Evi Nemeth, Garth Snyder, Scott Seebass & Trent R. Hein,<newline>
|

``Unix System Administration Handbook'', Prentice-Hall, 1995<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$45-$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).

One good source of additional information is the

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

<heading>Copyrights</heading>

|
|
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>I have only 4 MB of RAM. 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! Must I 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>Can Windows 95 co-exist with 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>
|
|
Yes. DOS extended partitions are mapped in at the end of
|
|
the other ``slices'' in FreeBSD, e.g. your D: drive might
|
|
be /dev/sd0s5, your E: drive /dev/sd0s6, and so on. This
|
|
example assumes, of course, that your extended partition is
|
|
on SCSI drive 0. For IDE drives, substitute ``wd'' for ``sd''
|
|
and so on. You otherwise mount them exactly like you would
|
|
mount any other DOS drive, e.g.:
|
|
|
|
<p>
|
|
mount -t msdos /dev/sd0s5 /dos_d
|
|
|
|
|
|
<sect1>
|
|
<heading>Can I run DOS binaries under FreeBSD?</heading>
|
|
|
|
<p>
|
|
Not yet, though BSDI has just donated their <tt/rundos/ DOS emulation
|
|
subsystem which we're now working on integrating and enhancing.

Send mail to

|
|
if you're interested in joining this effort!
|
|
|
|
For now, 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).

|
|
<heading>Help! I can't install from tape!<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>How can I install onto a large SCSI disk?</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 cylinders 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

<heading>When I boot FreeBSD I get ``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>I can't get past the boot manager's `F?' prompt.</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 ``>1GB drive support''), try
|
|
toggling its setting and reinstalling FreeBSD.
|
|
|
|
<sect1>
|
|
<heading>How can I add my new hard disk to my FreeBSD system?</heading>
|
|
<p>
|
|
The easiest way to do this is from the installation program. You can
|
|
start the installation program by running /stand/sysinstall as root
|
|
(note however that this will require kernel support for running
|
|
gzipped executables - the one shipped with FreeBSD does <tt /not/
|
|
support this).
|
|
<p>
|
|
Alternatively, if you still have the install floppy, you can just
|
|
reboot from that.
|
|
<p>
|
|
Select the ``Express Mode for Experts'' option, which will put you
|
|
straight into the fdisk editor, and create a single slice on the
|
|
disk. (Make sure you are editing the right disk!) Press `w' to write
|
|
your changes to the disk. Say ``No'' when asked if you want to
|
|
remain compatible with other operating systems, and ``Yes'' when
|
|
asked if you know what you're doing.
|
|
<p>
|
|
Pressing `q' to quit will transfer you to the disklabel editor.
|
|
Divide up your FreeBSD slice according to taste and press `w' when
|
|
you are happy with the way it looks. Again, say ``Yes'' when asked
|
|
for confirmation, and press `q' to quit.
|
|
<p>
|
|
At this point, you will be asked if you wish to commit your changes.
|
|
Do <tt /not/ do this! Instead, keep pressing the `escape' key until
|
|
you exit the installation program. If you booted from the install
|
|
floppy, the system will reboot at this point. Remember to remove the
|
|
floppy from the drive first!
|
|
<p>
|
|
All we need to do now is to put a filesystem on the disk. Just typing
|
|
newfs followed by the device name will do this. For example, if the
|
|
new disk is your second SCSI drive and you put its FreeBSD slice on
|
|
slice 1, the command would be:-
|
|
<verb>
|
|
newfs /dev/sd1s1
|
|
</verb>
|
|
``newfs'' will choose sensible default values which will be good
|
|
enough for most purposes; if you need to tune the filesystem, the man
|
|
page for newfs describes all the options. A common optimisation is to
|
|
use the option `-i 2048' to put more inodes on a disk which is going
|
|
to be used for a news spool (the default is to have an inode for
|
|
every 4096 bytes of data - note that there was an error in the man
|
|
page in 2.1.0 in this respect).
|
|
<p>
|
|
If that sentence did not make any sense to you, you definitely do not
|
|
need to worry about tuning your filesystem! :-)

<heading>I have an IDE drive with lots of bad blocks on it...</heading>
|
|
<p>
|
|
FreeBSD's bad block (the ``<tt/bad144/'' command) handling is
|
|
still not 100% (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 RAM. Will this cause any 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. (Note that this
|
|
is not required if you have a PCI motherboard).
|
|
|
|
<sect1>
|
|
<heading>I keep seeing messages like ``<tt/ed1: timeout/''.</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. Boot with the -c option and
|
|
change the ed0/de0/... entry to match your board.
|
|
|
|
<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>I live outside the US. Can I use DES encryption?</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:

|
|

|
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

|
|
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 the <url url="http://www.freebsd.org/handbook/kernelconfig.html"
|
|
name="Handbook entry on 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? :)

FreeBSD supports APM on certain machines. Please look in the

<sect1>
|
|
<heading>FreeBSD does not recognise my Bustek 742a EISA SCSI.</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 doesn'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 you 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.

<heading>I want to run X, how do I go about it?</heading>
|
|
|
|
<p>
|
|
First, get the XFree86(tm) distribution of X11R6 from
|
|
<tt/XFree86.cdrom.com/ The version you want for FreeBSD 2.X and
|
|
later is <tt/XFree86 3.1.1/. Follow the instructions for
|
|
installation carefully. You may then wish to read the
|
|
documentation for the <tt/ConfigXF86/ tool, which assists you in
|
|
configuring XFree86(tm) for your particular graphics
|
|
card/mouse/etc.
|
|
|
|
You may also wish to investigate the Xaccel server, which is
|
|
available at a very reasonable price. See section

You don't have a math co-processor, right?
|
|
You will need to add the alternative 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_EMULATE/

<sect1>
|
|
<heading>Is there an easy way to get hold of applications?</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.

<heading>When I run a SCO/iBCS2 application, it bombs on <tt/socksys/.</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 & 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_HACK/ when you compile the system.

<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.

<heading>Why doesn't chmod change the permissions on symlinks?</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>When I mount a CDROM, I get ``Incorrect super block''.</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_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 mount a CDROM, I get ``Device not configured''.</heading>
|
|
<p>
|
|
This generally means that there is no CDROM in the CDROM drive,
|
|
or the drive is not visible on the bus. Feed the drive
|
|
something, and/or check its master/slave status if it is
|
|
IDE (ATAPI).

<sect1>
|
|
<heading>How can I use the NT loader to boot FreeBSD?</heading>
|
|
<p>
|
|
The general idea is that one copies the first sector of your
|
|
native root Linux or FreeBSD partition into a file in the DOS/NT
|
|
partition. Assuming one names that file something like
|
|
<tt>c:\bootsect.lnx</tt> or <tt>c:\bootsect.bsd</tt>
|
|
(inspired by <tt>c:\bootsect.dos</tt>) one can then edit the
|
|
<tt>c:\boot.ini</tt> file to come up with something like
|
|
this:
|
|
<verb>
|
|
[boot loader]
|
|
timeout=30
|
|
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
|
|
[operating systems]
|
|
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows NT"
|
|
C:\BOOTSECT.LNX="Linux"
|
|
C:\BOOTSECT.BSD="FreeBSD"
|
|
C:\="DOS"
|
|
</verb>
|
|
This procedure assumes that DOS, NT, Linux, FreeBSD, or whatever
|
|
have been installed into their respective fdisk partitions on the
|
|
<bf/same/ disk. In my case DOS & NT are in the first fdisk
|
|
partition, Linux in the second, and FreeBSD in the third. I also
|
|
installed Linux and FreeBSD to boot from their native partitions,
|
|
not the disk MBR, and without delay.
|
|
|
|
Mount a DOS-formatted floppy (if you've converted to NTFS) or the
|
|
FAT partition, under, say, <tt>/mnt</tt>.
|
|
|
|
In Linux:
|
|
<verb>
|
|
dd if=/dev/sda2 of=/mnt/bootsect.lnx bs=512 count=1
|
|
</verb>
|
|
|
|
In FreeBSD:
|
|
<verb>
|
|
dd if=/dev/rsd0a of=/mnt/bootsect.bsd bs=512 count=1
|
|
</verb>
|
|
|
|
Reboot into DOS or NT. NTFS users copy the <tt/bootsect.lnx/
|
|
and/or the <tt/bootsect.bsd/ file from the floppy to
|
|
<tt/C:\/. Modify the attributes (permissions) on
|
|
<tt/boot.ini/ with:
|
|
|
|
<verb>
|
|
attrib -s -r c:\boot.ini
|
|
</verb>
|
|
|
|
Edit to add the appropriate entries from the example
|
|
<tt/boot.ini/ above, and restore the attributes:
|
|
|
|
<verb>
|
|
attrib -r -s c:\boot.ini
|
|
</verb>
|
|
|
|
If Linux or FreeBSD are booting from the MBR, restore it with the
|
|
DOS ``<tt>fdisk /mbr</tt>'' command after you reconfigure them to
|
|
boot from their native partitions.

If it's parallel, and the only problem is that it's terribly

This is a known problem with the ATI Mach 64 video card.
|
|
The problem is that this card 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.
|
|
(This will put the kernel into configuration mode).
|
|
<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>That works, but 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.

<heading>Now everything runs great, except for X Window!</heading>
|

<p>

Some newer ATI Mach 64 video cards (notably ATI Mach Xpression)
|
|
do not run with the current version of <tt/XFree86/; the screen
|
|
goes black when you start X Window, or it works with strange
|
|
problems. 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">

<heading>What is a virtual console?</heading>
|
|
<p>
|
|
Virtual consoles, put simply, enable you to have several
|
|
simultaneous sessions on the same machine without doing anything
|
|
complicated like setting up a network or running X.
|
|
<p>
|
|
When the system starts, it will display a login prompt on
|
|
the monitor after displaying all the boot messages. You can
|
|
then type in your login name and password and start working (or
|
|
playing!) on the first virtual console.
|
|
<p>
|
|
At some point, you will probably wish to start another
|
|
session, perhaps to look at documentation for a program
|
|
you are running or to read your mail while waiting for an
|
|
FTP transfer to finish. Just do Alt-F2 (hold down the Alt
|
|
key and press the F2 key), and you will find a login prompt
|
|
waiting for you on the second ``virtual console''! When you
|
|
want to go back to the original session, do Alt-F1.
|
|
<p>
|
|
The default FreeBSD installation has three virtual consoles
|
|
enabled, and Alt-F1, Alt-F2, and Alt-F3 will switch between
|
|
these virtual consoles.
|
|
|
|
<sect1>
|
|
<heading>How do I access the virtual consoles from X?</heading>
|
|
<p>
|
|
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.

<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"
|

This file describes how to setup sup on your machine. You may

<heading>How cool is FreeBSD?</heading>
|
|
<p>
|
|
Q. 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.
|
|
<p>
|
|
A. 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 uses the ``<tt/HALT/'' instruction when the
|
|
system is idle thus lowering its energy consumption and therefore
|
|
the heat it generates.
|
|
|
|
<sect1>
|
|
<heading>Who's scratching in my memory banks??</heading>
|
|
<p>
|
|
Q. 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.
|
|
<p>
|
|
A. 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?</heading>
|
|

The entire process of creating installation disks and source and

be enough to get you started.

<sect1>
|
|
<heading>"make world" clobbers my existing installed binaries.</heading>
|
|
|
|
<p>
|
|
Yes, this is the general idea; as its name might suggest,
|
|
``make world'' rebuilds every system binary from scratch, so
|
|
you can be certain of having a clean and consistent
|
|
environment at the end (which is why it takes so long).
|
|
<p>
|
|
If the environment variable <tt/DESTDIR/ is defined 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>${DESTDIR}</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 boots, it says ``(bus speed defaulted)''.</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_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.

If you start X with 'startx', the permissions on /dev/console will

|
|

<p>

This is because of the way console permissions are set by default.

On a multi-user system, one doesn't necessarily want just any user

to be able to write on the system console. For users who are logging

|
directly onto a machine with a VTY, the <tt/fbtab(5)/ file exists

to solve such problems.

/dev/ttyv0 0600 /dev/console

<heading>How are Plug N Play ISA cards detected and initialised?</heading>
|
|
<p>
|
|
By: Frank Durda IV <tt><uhclem@nemesis.lonestar.org></tt>
|
|
|
|
In a nutshell, there a few I/O ports that all of the PnP boards
|
|
respond to when the host asks if anyone is out there. So when
|
|
the PnP probe routine starts, he asks if there are any PnP boards
|
|
present, and all the PnP boards respond with their model # to
|
|
a I/O read of the same port, so the probe routine gets a wired-OR
|
|
``yes'' to that question. At least one bit will be on in that
|
|
reply. Then the probe code is able to cause boards with board
|
|
model IDs (assigned by Microsoft/Intel) lower than X to go
|
|
``off-line''. It then looks to see if any boards are still
|
|
responding to the query. If the answer was ``<tt/0/'', then
|
|
there are no boards with IDs above X. Now probe asks if there
|
|
are any boards below ``X''. If so, probe knows there are boards
|
|
with a model numbers below X. Probe then asks for boards greater
|
|
than X-(limit/4) to go off-line. If repeats the query. By
|
|
repeating this semi-binary search of IDs-in-range enough times,
|
|
the probing code will eventually identify all PnP boards present
|
|
in a given machine with a number of iterations that is much lower
|
|
than what 2^64 would take.
|
|
|
|
The IDs are two 32-bit fields (hence 2ˆ64) + 8 bit checksum.
|
|
The first 32 bits are a vendor identifier. They never come out
|
|
and say it, but it appears to be assumed that different types of
|
|
boards from the same vendor could have different 32-bit vendor
|
|
ids. The idea of needing 32 bits just for unique manufacturers
|
|
is a bit excessive.
|
|
|
|
The lower 32 bits are a serial #, ethernet address, something
|
|
that makes this one board unique. The vendor must never produce
|
|
a second board that has the same lower 32 bits unless the upper
|
|
32 bits are also different. So you can have multiple boards of
|
|
the same type in the machine and the full 64 bits will still be
|
|
unique.
|
|
|
|
The 32 bit groups can never be all zero. This allows the
|
|
wired-OR to show non-zero bits during the initial binary search.
|
|
|
|
Once the system has identified all the board IDs present, it will
|
|
reactivate each board, one at a time (via the same I/O ports),
|
|
and find out what resources the given board needs, what interrupt
|
|
choices are available, etc. A scan is made over all the boards
|
|
to collect this information.
|
|
|
|
This info is then combined with info from any ECU files on the
|
|
hard disk or wired into the MLB BIOS. The ECU and BIOS PnP
|
|
support for hardware on the MLB is usually synthetic, and the
|
|
peripherals don't really do geniune PnP. However by examining
|
|
the BIOS info plus the ECU info, the probe routines can cause the
|
|
devices that are PnP to avoid those devices the probe code cannot
|
|
relocate.
|
|
|
|
Then the PnP devices are visited once more and given their I/O,
|
|
DMA, IRQ and Memory-map address assignments. The devices will
|
|
then appear at those locations and remain there until the next
|
|
reboot, although there is nothing that says you can't move them
|
|
around whenever you want.
|
|
|
|
There is a lot of oversimplification above, but you should get
|
|
the general idea.
|
|
|
|
Microsoft took over some of the primary printer status ports to
|
|
do PnP, on the logic that no boards decoded those addresses for
|
|
the opposing I/O cycles. I found a genuine IBM printer board
|
|
that did decode writes of the status port during the early PnP
|
|
proposal review period, but MS said ``tough''. So they do a
|
|
write to the printer status port for setting addresses, plus that
|
|
use that address + <tt/0x800/, and a third I/O port for reading
|
|
that can be located anywhere between <tt/0x200/ and <tt/0x3ff/.

<heading>Kernel Configuration</heading>
|
|
<p>
|
|
<sect1>
|
|
<heading>I'd like to customize my kernel. Is it difficult?<label id="make-kernel"></heading>
|
|
<p>
|
|
Not at all! First, 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, unlike most commercial UNIX vendors, we have a policy
|
|
of <bf/NOT/ shipping our kernel code in binary object form.
|
|
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/really/ happening.
|
|
|
|
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 8 should only be undertaken if steps 6 and 7
|
|
succeed. 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 step 7 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.

<heading>My kernel compiles fail because <tt/_hw_float/ is missing.</heading>
|
|
|
|
<p>
|
|
Let me guess. You removed <tt/npx0/ from your kernel configuration
|
|
file because you don't have a math co-processor, right? Wrong! :-)
|
|
The <tt/npx0/ is <bf/MANDATORY/. Even if you don't have a

mathematic co-processor, you <bf/must/ include the <tt/npx0/

<heading>Interrupt conflicts with multi-port serial code.</heading>
|
|
<p>
|
|
Q. 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?
|
|
|
|
<p>
|
|
A. The problem here is that FreeBSD has code built-in to keep the
|
|
kernel from getting trashed due to 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>How do I enable support for QIC-40/80 drives?</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.

|

|
<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
|

<sect1>
|
|
<heading>I have 128 MB of RAM but the system only uses 64 MB.</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/

|

<heading>FreeBSD 2.0 panics with ``kmem_map too small!''</heading>
|
|
|
|
<p>
|
|
<tt /Note/ The message may also be ``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 <n> 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/.

<heading>Where are the system start-up configuration files?</heading>
|
|
|
|
<p>
|
|
As of 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>.

``Diskless booting'' means that the FreeBSD box is booted over a

<heading>Can a FreeBSD box be used as a dedicated network router?</heading>
|
|
|
|
<p>
|
|
Internet standards and good engineering practice prohibit us from
|
|
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.

A possible cause for this is IJPPPs' use of predictor1

most likely it.

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.

additional parameter on the <tt/ifconfig(1)/ command line. The

<heading>Why do I have to use the FQDN for hosts on my site?</heading>
|
|
<p>
|
|
You will probably find that the host is actually in a different
|
|
domain; for example, if you are in foo.bar.edu and you wish to reach
|
|
a host called ``mumble'' in the bar.edu domain, you will have to
|
|
refer to it by the fully-qualified domain name, ``mumble.bar.edu'',
|
|
instead of just ``mumble''.
|
|
<p>
|
|
Traditionally, this was allowed by BSD BIND resolvers. However
|
|
the current version of <em>BIND</em> that ships with FreeBSD
|
|
no longer provides 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 continued across <tt>mumble.bar.edu</tt>, and
|
|
<tt>mumble.edu</tt>. Have a look at RFC 1535 for why this
|
|
was considered bad practice, or 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 it.

<sect1><heading>Sendmail says ``mail loops back to myself''</heading>
|
|
<p>
|
|
This is answered in the sendmail FAQ as follows:-
|
|
<verb>
|
|
* I'm getting "Local configuration error" messages, such as:
|
|
|
|
553 relay.domain.net config error: mail loops back to myself
|
|
554 <user@domain.net>... Local configuration error
|
|
|
|
How can I solve this problem?
|
|
|
|
You have asked mail to the domain (e.g., domain.net) to be
|
|
forwarded to a specific host (in this case, relay.domain.net)
|
|
by using an MX record, but the relay machine doesn't recognize
|
|
itself as domain.net. Add domain.net to /etc/sendmail.cw
|
|
(if you are using FEATURE(use_cw_file)) or add "Cw domain.net"
|
|
to /etc/sendmail.cf.
|
|
</verb>
|
|
<p>
|
|
The sendmail FAQ is in <tt>/usr/src/usr.sbin/sendmail</tt>
|
|
and is recommended reading if you want to do any
|
|
``tweaking'' of your mail setup.
|
|
|
|
<sect1>
|
|
<heading>How do I use sendmail for mail delivery with UUCP?</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 didn't install your system with full sources,
|
|
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 panic, 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 to m4 configuration.
|
|
|
|
<p>
|
|
For UUCP delivery, you are best advised to use 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 can 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.
|

<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?</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.
|
|

<heading>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 any old configuration files you have, though.
|
|
|
|
<sect1>
|
|
<heading>How do I access the serial ports on FreeBSD?</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 enable support for a 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_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>Can FreeBSD handle multiport serial cards sharing irqs?</heading>
|
|
<p>
|
|
Not yet. You'll have to use a different irq for each card.
|
|
|
|
<sect1>
|
|
<heading>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.

<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 connect a dumb terminal 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).
|
|
|

|
|
<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 can 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&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&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?<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>The <tt/@/ sign for the pn capability doesn't work!</heading>
|
|
<p>
|
|
The <tt/@/ sign in the phone number 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>Do I have to type in the bps rate every time I do that?</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 access a number of hosts through a terminal server.</heading>
|
|
<p>
|
|
Rather than waiting until you're connected and typing
|
|
``<tt/CONNECT <host>/'' each time, use tip's <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.

<p>

This is often a problem where a university has several modem lines
|
|
and several thousand students trying to use them...
|
|
<p>
|
|
Make an entry for your university in <tt>/etc/remote</tt>
|
|
and use <tt>\@</tt> for the <tt/pn/ capability:
|
|
<verb>

big-university:\

|
|
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>Why do 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=<single-char>/'' followed by a newline.
|
|
<tt/<single-char>/ is any single character. If you leave
|
|
out <tt/<single-char>/, 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/<single-char>/ 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>$HOME/.tiprc</tt>
|
|
file:
|
|
<verb>
|
|
force=<single-char>
|
|
</verb>
|
|
|
|
<sect1>
|
|
<heading>Suddenly everything I type is in UPPER CASE??</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>How can I run zmodem with <tt/tip/?</heading>

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 <files>/'' to send them to the

remote system.
