---------
|
||
|
||
Welcome to the FreeBSD 2.0 FAQ! This document tries to answer some of
|
||
the most frequently asked questions about FreeBSD 2.0.
|
||
If there's something you're having trouble with and you do not see it
|
||
here, please send email to:
|
||
|
||
<FreeBSD-questions@FreeBSD.ORG>
|
||
|
||
|
||
Some of the instructions here will also refer to auxiliary utilities
|
||
in the /usr/src/share/FAQ directory. CDROM purchasers and net folks
|
||
who've grabbed the FreeBSD 2.0 `srcdist' will have these files. If
|
||
you don't have the source distribution, then you can either grab the
|
||
whole thing from:
|
||
|
||
ftp.FreeBSD.ORG:pub/FreeBSD/FreeBSD-current
|
||
|
||
Or you can grab only those files you're interested in straight out of
|
||
the FreeBSD-current distribution in:
|
||
|
||
ftp.FreeBSD.ORG:pub/FreeBSD/FreeBSD-current/src
|
||
|
||
0.1: What is FreeBSD?
|
||
|
||
FreeBSD 2.0 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:
|
||
|
||
More robust and extensive PC device support
|
||
System V-style IPC, messaging and semaphores
|
||
Shared Libraries
|
||
Much improved virtual memory code
|
||
Better console driver support
|
||
Network booting (diskless) support
|
||
Yellow Pages support
|
||
Full support of the PCI bus
|
||
Loadable kernel modules
|
||
Too many additional utilities and applications to mention
|
||
|
||
|
||
0.2: What are the FreeBSD mailing lists, and how can I get on them?
|
||
|
||
The following mailing lists are provided for FreeBSD users and
|
||
developers. For more information, send to
|
||
<majordomo@FreeBSD.ORG> and include a single line saying
|
||
``help'' in the body of your message.

||
0.3: What are the various FreeBSD news groups?
|
||
|
||
While there are no groups currently dedicated to FreeBSD, you may find
|
||
the following groups useful.

1 Installation
|
||
--------------
|
||
|
||
1.1: I just installed my system and rebooted. Now I can't find the
|
||
extract or configure programs, where did they go?
|
||
|
||
These two commands are just shell functions defined in /.profile. To
|
||
get these back, boot FreeBSD with a `-s' at the boot prompt.
|
||
|
||
|
||
1.2: I want to install FreeBSD onto a SCSI disk that has more than
|
||
1024 cylinders. How do I do it?
|
||
|
||
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
|
||
`pfdisk' (located in the tools/ subdirectory) which can be used for
|
||
this purpose.
|
||
|
||
|
||
1.3: When I boot FreeBSD it says ``Missing Operating System''.
|
||
|
||
See question 1.2. 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.
|
||
|
||
|
||
1.4: I have an IDE drive with lots of bad blocks on it and FreeBSD doesn't
|
||
seem to install properly.
|
||
|
||
FreeBSD's bad block (bad144) 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 *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.
|
||
|
||
1.5: I have 32MB of memory, should I expect any special problems?
|
||
|
||
No. FreeBSD 2.0 comes with bounce buffers which allows your bus
|
||
mastering controller access to greater than 16MB.
|
||
|
||
1.6: Do I need to install the complete sources?
|
||
|
||
In general, no. However, we would strongly recommend that you
|
||
install, at a minimum, the `base' source kit, which includes several
|
||
of the files mentioned here, and the `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 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 /usr/src 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.
|
||
|
||
1.7: DES encryption software can not be exported from the United
|
||
States. If I live outside the US, how can I encrypt passwords?
|
||
|
||
Since the DES encryption algorithm, which is used by passwd(1) and
|
||
friends to encrypt passwords cannot legally be exported from the US,
|
||
non-US users should not download this software 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:
|
||
|
||
South Africa: braae.ru.ac.za:/pub/FreeBSD/securedist/
|
||
owl.und.ac.za (currently uncertain)
|
||
Iceland: ftp.veda.is:/pub/crypt/FreeBSD/
|
||
|
||
The non-US securedist can be used as a direct replacement for the
|
||
encumbered US securedist. This 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
|
||
braae.ru.ac.za.
|
||
|
||
There is also a mailing list for the discussion of non-US encryption
|
||
software. For more information, send an email message with a single
|
||
line saying ``help'' in the body of your message to
|
||
<majordomo@braae.ru.ac.za>.

2 Hardware compatibility
|
||
------------------------
|
||
|
||
2.1: What kind of hard drives does FreeBSD run on?
|
||
|
||
FreeBSD supports ST-506 (sometimes called ``MFM''), RLL, and ESDI
|
||
drives, which are usually connected to WD-1002, WD-1003, or WD-1006
|
||
controllers (although clones should also work). FreeBSD also supports
|
||
IDE and SCSI hard drives.
|
||
|
||
2.2: What SCSI controllers are supported?
|
||
|
||
FreeBSD supports the following SCSI controllers:
|
||
|
||
Adaptec AH-154x Series <ISA>
|
||
AH-174x Series <EISA>
|
||
AH-152x Series <ISA>
|
||
Buslogic BT-445 Series <VLB> (but see section 1.5)
|
||
BT-545 Series <ISA>
|
||
BT-742 Series <EISA>
|
||
BT-747 Series <EISA>
|
||
BT-964 Series <PCI>
|
||
Future Domain TMC-8xx/950 Series <ISA>
|
||
PCI Generic NCR 53C810 based controllers <PCI>
|
||
ProAudioSpectrum Zilog 5380 based controllers <ISA>
|
||
SCSI-2 controllers <ISA>
|
||
Seagate ST-01/02 Series <ISA>
|
||
UltraStor UH-14f Series <ISA>
|
||
UH-34f Series <EISA/VLB>
|
||
|
||
|
||
2.3: What CD-ROM drives are supported by FreeBSD?
|
||
|
||
Any SCSI drive connected to a supported controller. Mitsumi
|
||
LU002(8bit), LU005(16bit) and FX001D(16bit 2x Speed).
|
||
|
||
FreeBSD does NOT support drives connected to a Sound Blaster or
|
||
non-SCSI SONY or Panasonic drives at this time. A general rule of thumb when
|
||
selecting a CDROM drive for FreeBSD use is to buy a very standard SCSI
|
||
model; they cost more, but deliver very solid performance in return.
|
||
Do not be fooled by very cheap drives that, in turn, deliver VERY LOW
|
||
performance! As always, you get what you pay for.
|
||
|
||
The Mitsumi driver is known to be extremely slow compared to SCSI
|
||
drives.
|
||
|
||
|
||
2.4: What multi-port serial cards are supported by FreeBSD?
|
||
|
||
AST/4 and BOCA 4/8/16 port cards. Some unnamed clone cards have also
|
||
been known to work, especially those that claim to be AST compatible.
|
||
Check the sio(4) man page to get more information on configuring such
|
||
cards.
|
||
|
||
|
||
2.5: Does FreeBSD support the AHA-2742 SCSI adapter from Adaptec?
|
||
|
||
No, FreeBSD does not. This is due to Adaptec's unwillingness to
|
||
supply programming information under other than non-disclosure. This
|
||
is unfortunate, but there's nothing we can do about it.
|
||
|
||
|
||
2.6: I have a Mumbleco bus mouse. Is it supported and if so, how do I set
|
||
it up for XFree86?
|
||
|
||
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:
|
||
|
||
device mse0 at isa? port 0x23c tty irq6 vector mseintr
|
||
|
||
|
||
2.7: I have a PS/2 mouse (`keyboard' mouse) [Alternatively: I have a
|
||
laptop with a track-ball mouse]. How do I use it?
|
||
|
||
The PS/2 mouse is part of the system. See the psm0 driver description
|
||
/sys/doc/options.doc.
|
||
|
||
|
||
2.8: What types of tape drives are supported under FreeBSD?
|
||
|
||
FreeBSD supports SCSI, QIC-02 and QIC-40/80 (Floppy based) tape
|
||
drives. This includes 8-mm (aka Exabyte) and DAT drives.
|
||
|
||
|
||
2.9: What sound cards are supported by FreeBSD?
|
||
|
||
FreeBSD supports the SoundBlaster, SoundBlaster Pro, Pro Audio
|
||
Spectrum 16, AdLib and Gravis UltraSound sound cards. There is also
|
||
limited support for MPU-401 and compatible MIDI cards. The
|
||
SoundBlaster 16 and SoundBlaster 16 ASP cards are not yet supported.
|
||
NOTE: This is only for sound! This driver does not support CD-ROMs,
|
||
SCSI or joysticks on these cards.
|
||
|
||
|
||
2.10: What network cards does FreeBSD support?
|
||
|
||
There is support for the following cards:
|
||
|
||
`ed' driver:
|
||
NE2000 and 1000
|
||
WD/SMC 8003, 8013 and Elite Ultra (8216)
|
||
3Com 3c503
|
||
And clones of the above
|
||
|
||
`ie' driver:
|
||
AT&T EN100/StarLAN 10
|
||
3Com 3c507
|
||
|
||
`is' driver:
|
||
Isolan AT 4141-0
|
||
Isolink 4110
|
||
|
||
`ep' driver:
|
||
3com 3c509 (*)
|
||
|
||
`el' driver:
|
||
3com 3c501 (*)
|
||
|
||
`ze' driver:
|
||
IBM PCMCIA credit card adapter
|
||
|
||
(*)The `ep' and `el' driver is known to have some problems; see the
|
||
/usr/src/KNOWNBUGS file for more details.
|
||
|
||
|
||
2.11: I have a 386/486sx/486SLC machine without a math co-processor.
|
||
Will this cause me any problems?
|
||
|
||
Generally no, but there are circumstances where you will take a hit,
|
||
either in performance or accuracy of the math emulation code (see
|
||
section 4.1). In particular, drawing arcs in X will be VERY slow. It
|
||
is highly recommended that you lay out the $50 or so for a math
|
||
co-processor; it's well worth it. 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.
|
||
|
||
2.12: I am about to buy a new machine to run FreeBSD on and
|
||
want an idea of what other people are running. Is there list
|
||
of other systems anywhere?
|
||
|
||
Yes. Please look at the file FAQ/OTHER-FAQS/Systems.FAQ. This file
|
||
is a listing of hardware that people are running in their machines.
|
||
Please note, this is a raw listing of equipment that other users
|
||
have sent in.
|
||
|
||
|
||
|
||
3 Commercial Applications
|
||
-------------------------
|
||
|
||
Note: This section is still very sparse, though we're hoping, of
|
||
course, that companies will add to it! :) The FreeBSD group has no
|
||
financial interest in any of the companies listed here but simply
|
||
lists them as a public service (and feels that commercial interest in
|
||
FreeBSD can have very positive effects on FreeBSD's long-term
|
||
viability). We encourage commercial software vendors to send their
|
||
entries here for inclusion.
|
||
|
||
|
||
<XXX> 3.1: Where can I get Motif for FreeBSD?
|
||
|
||
|
||
|
||
4 User Applications
|
||
-------------------
|
||
|
||
4.1: I want to run X, how do I go about it?
|
||
|
||
First, get the XFree86 distribution of X11R5 from XFree86.cdrom.com.
|
||
The version you want for FreeBSD 1.1 and later is XFree86 2.1. Follow
|
||
the instructions for installation carefully. You may then wish to read
|
||
the documentation for the ConfigXF86 tool, which assists you in
|
||
configuring XFree86 for your particular graphics card/mouse/etc.
|
||
|
||
|
||
4.1: 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?
|
||
|
||
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.
|
||
|
||
options GPL_MATH_EMULATE
|
||
|
||
NOTE: You will need to remove the MATH_EMULATE option when you do this.
|
||
|
||
|
||
4.2: 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?
|
||
|
||
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 deinstalled again easily without having to know
|
||
the gory details. CDROM people will have a packages/ directory on
|
||
their CD, others can get the currently available packages from:
|
||
|
||
ftp.FreeBSD.ORG:pub/FreeBSD/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 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.
|
||
|
||

|
||
5 Miscellaneous Questions
|
||
----------------
|
||
|
||
5.1: I've heard of something called FreeBSD-current. How do I run it, and
|
||
where can I get more information?
|
||
|
||
Read the file /usr/src/share/FAQ/FreeBSD.current.policy,
|
||
it will tell you all you need to know.
|
||
|
||
|
||
5.2: What is this thing called `sup', and how do I use it?
|
||
|
||
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.
|
||
|
||
To use it, you need to have direct internet connectivity (not just
|
||
mail or news). First, pick up the sup_bin.tgz package from:
|
||
|
||
ftp.FreeBSD.ORG:pub/FreeBSD/packages
|
||
|
||
Second, read the file /usr/src/share/FAQ/FreeBSD.sup.faq.
|
||
|
||
This file describes how to setup sup on your machine. You may also
|
||
want to look at /usr/src/share/FAQ/FreeBSD.*.supfile,
|
||
which are a set of supfiles for supping from FreeBSD.ORG.
|
||
|
||
|
||
5.3: How do I create customized installation disks that I can give
|
||
out to other people at my site?
|
||
|
||
The entire process of creating installation disks and source and
|
||
binary archives is automated by various targets in
|
||
/usr/src/etc/Makefile. The information there should be enough to get
|
||
you started.
|
||
|
||
5.4: How do I re-build my system without clobbering the existing
|
||
installed binaries?
|
||
|
||
If you define the environment variable DESTDIR while running `make
|
||
world' or `make install', the newly-created binaries will be deposited
|
||
in a directory tree identical to the installed one, rooted at
|
||
${DESTDIR}. Some random combination of shared libraries modifications
|
||
and program rebuilds can cause this to fail in `make world', however.
|
||
|
||
|
||
5.5: When my system booted, it told me that ``(bus speed defaulted)''.
|
||
What does that mean?
|
||
|
||
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 ``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.
|
||
|
||
5.6: I would like to track changes to current and do not have net access.
|
||
Is there any way besides downloading the whole tree?
|
||

5.7: How do I split up large binary files into smaller 240k files
|
||
like the distribution does?
|
||
|
||
Newer BSD based systems have a "-b" option to split that allows them to
|
||
split files on arbitary byte bondaries.
|
||
|
||
Here is an example from /usr/src/Makefile.
|
||
bin-tarball:
|
||
(cd ${DISTDIR}; \
|
||
tar cf - . \
|
||
gzip --no-name -9 -c | \
|
||
split -b 240640 - \
|
||
${RELEASEDIR}/tarballs/bindist/bin_tgz.)
|
||
|
||
|
||
<XXX> 5.8: I've had a couple of system panics and would like to be able
|
||
browse the system dumps. The normal kernel is stripped and
|
||
I don't want to run a bloated kernel. What can I do?
|
||
|
||
|
||
|
||
6 Kernel Configuration
|
||
----------------------
|
||
|
||
6.1: 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?
|
||
|
||
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:
|
||
|
||
#
|
||
# 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
|
||
|
||
|
||
6.2: FreeBSD is supposed to come with support for QIC-40/80 drives but
|
||
when I look, I can't find it.
|
||
|
||
You need to uncomment the following line in the generic config file
|
||
(or add it to your config file) and recompile.
|
||
|
||
controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr
|
||
disk fd0 at fdc0 drive 0
|
||
disk
|
||
fd1 at fdc0 drive 1
|
||
#tape ft0 at fdc0 drive 2
|
||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
||
You will have a device called /dev/ft0, which you can write to through
|
||
a special program to manage it called `ft' - see the man page on ft for
|
||
further details. Versions previous to -current also had some trouble dealing
|
||
wiht bad tape media; if you have trouble where ft seems to go back and forth
|
||
over the same spot, try grabbing the latest version of ft from /usr/src/sbin/ft
|
||
in current and try that.
|
||
|
||
|
||
6.3: Does FreeBSD support IPC primitives like those in System V?
|
||
|
||
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.
|
||
|
||
options SYSVSHM
|
||
options "SHMMAXPGS=64" # 256Kb of sharable memory
|
||
options SYSVSEM # enable for semaphores
|
||
options SYSVMSG # enable for messaging
|
||
|
||
Recompile and install.
|
||
|
||
|
||
6.4: Will FreeBSD ever support other architectures?
|
||
|
||
Several different groups have expressed interest in working on
|
||
multi-architecture support for FreeBSD. If you are interested in
|
||
doing so, please contact the developers at
|
||
<FreeBSD-hackers@FreeBSD.ORG> for more information on our
|
||
strategy for porting.
|
||
|
||
|
||
6.5: I just wrote a device driver for a Foobar Systems, Inc.
|
||
Integrated Adaptive Gronkulator card. How do I get the
|
||
appropriate major numbers assigned?
|
||
|
||
This depends on whether or not you plan on making the driver publicly
|
||
available. If you do, then please send us a copy of the driver source
|
||
code, plus the appropriate modifications to files.i386, a sample
|
||
configuration file entry, and the appropriate MAKEDEV code to create
|
||
any special files your device uses. If you do not, or are unable to
|
||
because of licensing restrictions, then character major number 32 and
|
||
block major number 8 have been reserved specifically for this purpose;
|
||
please use them. In any case, we'd appreciate hearing about your
|
||
driver on <FreeBSD-hackers@FreeBSD.ORG>.

||

||
7 System Administration
|
||
-----------------------
|
||
|
||
7.1: How do I add a user easily? I read the man page and am more confused
|
||
than ever! [Alternatively: I didn't read the man page, I never read
|
||
man pages! :-) ]
|
||
|
||
Use the adduser command.
|
||
|
||
|
||
<XXX> 7.2: I'm trying to use my printer and keep running into problems. I tried
|
||
looking at /etc/printcap, but it's close to useless. Any ideas?
|
||
|
||
|
||
|
||
8 Networking
|
||
------------
|
||
|
||
|
||
8.2: I've heard that you can use a FreeBSD box as a dedicated network
|
||
router - is there any easy support for this?
|
||
|
||
Internet standards and good engineering practice prohibit us from
|
||
providing packet forwarding by default in FreeBSD. You can enable
|
||
this support by adding `options GATEWAY' to your kernel configuration
|
||
file and recompiling. 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 routed(8),
|
||
or for more complex situations you may want to try GateD (available by
|
||
FTP from gated.Cornell.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.
|
||
|
||
|
||
8.3: Does FreeBSD support SLIP and PPP?
|
||
|
||
Yes. See the man pages for slattach(8) and/or 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 sliplogin(8).
|
||
You may also want to take a look at the slip FAQ in:
|
||
/usr/src/share/FAQ/Slip.FAQ
|
||
|
||
8.4: How do I get my network set up? I don't see how to make my
|
||
/dev/ed0 device!
|
||
|
||
In the Berkeley networking framework, network interfaces are only
|
||
directly accessible by kernel code. Please see the /etc/netstart 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.
|
||
|
||
8.5: How do I get my 3C503 to use the other network port?
|
||
|
||
Use `ifconfig ed0' to see whether the ALTPHYS flag is set, and then
|
||
use either `ifconfig ed0 altphys' if it was off, or `ifconfig ed0
|
||
-altphys' if it was on.
|
||
|
||
8.6: I'm having problems with NFS to/from FreeBSD and my Wuffotronics
|
||
Workstation / generic NFS appliance, where should I look first?
|
||
|
||
Certain PC network cards are better than others (to put it mildly) and
|
||
can sometimes cause problems with network intensive applications like
|
||
NFS. See /usr/src/share/FAQ/NFS.FAQ for more information on this
|
||
topic.
|
||
|
||
8.8: 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?]
|
||
|
||
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 ip_mroute_mod loadable kernel module and run mrouted.
