Section -1. (Where else to look)

	In the distribution of each of the *BSD systems, there is a LOT
	of documentation.  If you are completely unfamiliar with Unix,
	there is a reading list recommended in Section 1 of the FAQ.
	There are also various documents in the /usr/share/doc directory
	on the installed system.  Many of these give detailed information 
	about the design, history, and use of many of the pieces of the
	*BSD system you are interested.  Once you are familiar with
	Unix-like systems, you can probably graduate to the 'man'
	program.  The 'man' program is a series of manual pages which
	describe various parts of the system (kernel stuff, file
	formats, commands, 'C' standard functions, etc.) in enough
	detail to generally get you where you want to be.  The command
	'man man' will give you a lot of details.  The other command
	which might help is called 'apropos' (pronounced ap'-rO-pO).
	This command searches the title lines of every manual page
	looking for a match in the word you include as an argument.  If
	you have the system running, try the command 'apropos ttys' to
	get a feel for all the stuff that's out there.

	0.2          About this FAQ.
	0.2.1        I want to start up a thread about why *BSD is or isn't
		     as good as some other operating system. Can anyone
		     suggest a good reason why I shouldn't?

	2.0          Install process
	2.0.1        Boot disks (versions and media formats)
	2.0.1.1      I have the base system installed, and now I want to
		     install the rest of the system. Where did the 'extract'
		     program go? 
	2.0.1.2a     The floppy booted, but now the hard disk won't boot?
	2.0.1.2b     I am trying to reinstall. I run install and it loops
		     asking me if I want to use the whole disk? 
	2.0.1.4      What are the options on the boot prompt?
	2.0.1.5      I just used the '-s' option on the boot, but I can't
		     write anything onto the disk. What is wrong? If I use a
		     plain 'mount' command it tells me that my root file
		     system is read-only. 
	2.1          Binary distribution
	2.1.1        I want to install by NFS but I am having all kinds of
		     problems connecting to the Sun server where the files
		     are. 
	2.2          Configuration
	2.2.1        Partitions
	2.2.1.1      What is a 'disklabel' and why do I need one?
	2.2.1.2      What other kinds of information do I need if I really
		     want to tune my hard drive's performance in conjunction
		     with a newfs? 
	2.2.2        Common Disk Label Problems.
	2.2.2.1      Increasing the *BSD partition size.
	2.2.2.2      I can access the DOS partition on my second disk from
		     Unix but not DOS? Any suggestions? 
	2.2.2.3      I want to use my entire 2 Gig drive as the root
		     partition. Why doesn't it work? 
	2.5.3        How do I set up the system so that I can boot from more
		     than one operating system/file-loader without using
		     floppies? 
	2.2.3        How do I get the system to boot from the second hard
		     drive? 
	2.2.4        How do I disklabel my second hard drive?
	2.2.5        NetBSD and FreeBSD cannot handle disk geometry
		     translations, but it turns out that my disk geometry is
		     translated. It has five zones, each with a different
		     sec/track! What kind of things can I do about the disk
		     translation my hard disk controller uses? 
	2.2.6        I am having trouble installing on the EIDE hard drive.
		     What are some of the things that I need to look into? 
	2.2.7        My disk label is complaining about '256 heads' in the
		     disklabel. This is obviously bogus, but it doesn't seem
		     to be hurting anything. Is it Okay or should I fix it? 
	2.2.8        What are the options for the boot up prompt?
	2.2.9        I am having trouble installing WRT 'syslogd: bind: Can't
		     assign requested address' errors. What are some of the
		     things I should look at? I also am having trouble with
		     the network: 'starting network ... ifconfig: localhost:
		     badvalue'. 
	2.2.10       When I start up my system, it hangs for three or four
		     minutes during the 'netstart' program. Our network
		     nameserver is working OK, and I use it all the time; my
		     resolv.conf file says to use the network nameserver. Why
		     would netstart have such problems using it? 
	2.2.11       I am having trouble getting net aliases to work. What
		     could some of the problems be? 
	2.2.12       I'm having trouble with the networking code
		     (specifically the PPP stuff to my ISP). How can I debug
		     NetBSD's networking? 
	2.2.13       I want to hard wire my SCSI devices to a particular
		     device number. Is that possible? 
	2.3          Common installation problems.
	2.3.2        Endless reboot cycles.
	2.4          The computer just sits there, or 'that isn't right'.
	2.4.1        The boot disk works all right on one computer but not
		     another. 
	2.4.2        Really strange errors in the various *BSD flavors.
	2.4.2.2      Using the new code in NetBSD, I get a "panic: pdti
		     206067" in pmap_enter(). What should I do? 
	2.4.3a       I get the error "isr 15 and error: isr 17" on an NE2000
		     card. 
	2.4.3b       I have some card on IRQ2 and it doesn't work; why?
	2.4.3c       I am getting lousy performance out of my network card.
		     What are some of the other possibilities? 
	2.4.4        What is the difference between IRQ2 and IRQ9? Are they
		     really the same, or are they really different? 
	2.4.5        Some of my SCSI devices (like a tape drive) don't work;
		     why? 
	2.4.6        I want to use the Adaptec 1542C SCSI controller. What
		     are the problems/tricks you need to know to get it
		     working? 
	2.4.7        Is there a SCSI utility which works to fix up the random
		     problems I sometimes have with my drives? 
	2.4.8        My system boots OK off the floppy, but once I try to
		     boot from the hard drive, the message "changing root
		     device to sd0a" appears and the system hangs. What is
		     the most likely thing that I have done wrong? 
	2.5          Other common problems that are attributed to the
		     installation process but are caused other places. 
	2.5.1        I want to use more than 16 Megabytes of memory. Will any
		     of the BSD based systems support it? 
	2.5.2        I tried to use a device in my computer that should be
		     there. When I did, I got a "Device not configured
		     error." What do I do now? 
	2.6          Customizing the system to meet my needs.
	2.6.1        How do I get the system to not display the machine name,
		     but display our company name? 
	2.6.2        I have a program that, under normal circumstances,
		     starts once a second. This regularly causes inetd to
		     terminate the program with a 'server failing (looping),
		     service terminated' error. How do I fix this? 
	3.0          System Internals
	3.1          Kernel
	3.1.1        How do I build a kernel?
	3.1.1.1      Why does the kernel code for NetBSD still use the old
		     K&R style declarations when the ANSI declarations are SO
		     much better? 
	3.1.1.2      How do I port NetBSD to another platform?
	3.1.2        I want to do one of the following things:
		     * add a device not in the distributed kernel (third com
		       port, additional disk or tape, line printer driver,
		       etc).
		     * use a patch from the net or the patchkit to fix a
		       kernel bug.
		     * add another swap device.
		     * recompile the kernel to remove extraneous devices so
		       that it takes up less space.
		     * configure more pseudo-terminals to allow for more
		       xterms or network logins. 
	3.1.3        I want to build and profile a kernel. What do I need to
		     do? 
	3.1.4        Now that I have a kernel, how do I install it?
	3.1.5        My system is complaining about stray interrupt 7. Is my
		     machine going to explode or anything? 
	3.1.6        I keep getting "wd0c: extra interrupt". What does it
		     mean? 
	3.1.7        I keep getting silo overflow messages, but the system
		     doesn't seem to mind. Is there a problem? 
	3.1.8        I found a bug in the kernel. How do I report it?
	3.2          What exactly is this config file, anyway? What are all
		     of these cryptic notations? 
	3.2.1        Okay, fine. Why shouldn't I just add every device I can
		     find to the kernel, so I'll never have to recompile this
		     again? 
	3.2.2        What should I remove from the kernel?
	3.2.3        I can't get enough remote login sessions or xterm
		     sessions. I also can only get four sessions working at a
		     time. What can I do? 
	3.2.4        How do I get ddb, the kernel debugger, compiled into the
		     kernel and running? 
	3.2.5        I'm getting all kinds of errors when I try to build a
		     new version of GCC. How can I upgrade GCC to the most
		     current version? 
	3.2.6        Can I patch the current running OS image?
	3.2.7        Can I have more than one config file? Should I rename it
		     to something else? Any other hints? 
	3.2.8        I have been getting a lot of "virtual memory exhausted"
		     errors when I am compiling a program with a really big
		     static array. I have 128Meg of memory and 8Gig of swap.
		     How can this be happening? 
	3.2.8.1      I am running NetBSD and really DO have 128 Meg of
		     memory; but the generic kernel only sees the first
		     64Meg. How can I fix this? 
	3.2.8.2      How do I dedicate 16Meg of memory to nothing but disk
		     buffers? 
	3.2.9        Where can I learn more about all this?
	3.3          Other kernel related kind of questions.
	3.3.1        Has the method for system call changed in NetBSD?
	3.3.2        Does anyone have a system building script that takes
		     things like building a new config and multiple config
		     files into account? 
	3.3.3        How do I upgrade from my release version of NetBSD (and
		     probably FreeBSD) to the '-current' development sources?
		     
	3.3.4        Is there a Makefile that does all that happy
		     world-building stuff? 
	3.3.5        Can NetBSD do cross compilation?
	3.3.6        My network memory seems to be leaking. The numbers just
		     keep increasing slowly over time. Is there a problem I
		     need to worry about? 
	3.4          X11/XFree86/XS3
	3.4.1        What options should I define to get the X extensions
		     included? 
	3.4.2        Where can I get the FAQ for 'X'?
	3.4.3        Why does X drop characters when using xdm? When I run
		     xdm from the console, it keeps losing keystrokes and the
		     shift keys don't always work. Why? 
	3.4.4        What can I do to figure out why 'X' doesn't work with
		     NetBSD? 
	3.4.5        Under NetBSD and FreeBSD, xlock (or any other program
		     that uses passwords) fails to validate user passwords.
		     Anyone know why? 
	3.5          I want to run 'XYZA' which is dynamically linked and
		     from 'some other operating system'. What special things
		     do I have to do to get it working? 
	3.6          You promised to talk about timezones below. Are you
		     going to? 
	3.6.1        How do you change the timezone on NetBSD (FreeBSD
		     also?)? 
	3.6.2        The translation between seconds-since-the-epoch and date
		     differs by about 18 seconds between BSD and other Unixes
		     when running ntp; why? 
	3.7          How can I implement CVS to track MY changes to the
		     kernel source tree, yet still follow the -current
		     development tree? 
	3.8          Optional Op-codes for NetBSD, FreeBSD, and other
		     systems. 
	4.0          Introduction
	4.1          Common (sort of) Kernel-related problems
	4.1.1        Sometimes I have trouble with my system resetting the
		     terminal to seven bit mode. Isn't BSD eight bit clean? 
	4.1.2        How do you implement quotas on Net/2 derived BSD
		     systems? 
	4.1.3        What are the correct permissions for the /tmp, /usr/tmp,
		     and /var/tmp directories? 
	4.2          Available kernel add-ons
	4.2.1        Loadable Kernel Modules
	4.3          Other program building type problems.
	4.3.1        I am building a program that requires access to the
		     crypt library. Either I have it and it isn't getting
		     copied into the executable, or I don't have it; why? 
	4.3.2        I am having trouble with long file names in my
		     libraries. It seems like there is a 16 character limit
		     in the library somewhere. 
	4.3.3        I'm getting annoyed with having this "conflicting types
		     for `sys_errlist'" problem show up nearly every time I
		     build a program. What do I need to do? 
	4.4          System Administration Questions
	4.4.1        Where can I get good books about NetBSD or FreeBSD?
	4.4.2        I am concerned about system security. What should I do
		     to protect my system from net attacks? 
	4.4.3        How can I log failed login attempts?
	4.4.4        Can I use a Concatenated Filesystem with NetBSD?
	4.4.4.1      Why, when I type "ccdconfig ccd0 16 none /dev/wd0a >
		     /dev/wd1a", do I get back "ccdconfig: ioctl (CCDIOCSET):
		     /dev/ccd0d: Device not configured"? 
	4.4.5        I am really new to Unix System Administration. I need
		     some real basic help. 
	4.4.5.1      What is the System Administrator's user name?
	4.4.5.2      I can't log in as 'su'. What does that message mean when
		     I log in as root. 
	4.4.5.3      Are there any books I can 'bootstrap' myself with?
	4.4.5.4      How about some code examples?
	4.5.6        How do I change the default shell for a user?
	4.5          Daemon questions
	4.5.1        I'd like to use amd to mount a file system (/dev/sd0f
		     aka /usr/local) on another machine as "/usr/local".
		     What's the magic? 
	4.5.2        I am having trouble with my nameserver refusing to
		     accept 'nslookup's from my SunOS machine after I
		     installed the resolver fix. The exact error message is
		     "*** Can't find server name for address 194.100.46.2:
		     Query refused". Can you help? 
	4.5.3        Are there any alternatives to 'NIS' available for
		     NetBSD, et al.? 
	4.6          Adding new and removing old users.
	4.6.1        Where can I FTP the 'adduser' program?
	4.6.2        Where can I get a 'rmuser' script?
	5.0          Introduction
	5.1          A replacement curses program/library.
	5.2          Floppy Disk problems.
	5.2.1        How do I get a bootable floppy?
	5.2.2        How do I maximize the space on a mountable floppy disk. 
	5.3          Character Device Driver info
	5.3.1        Printers
	5.3.2        Terminals/Keyboards
	5.3.3        Modems/FAX Modems
	5.3.3.1      How do I add a modem to *BSD:
	5.3.3.4      Adding a Dial-in/Dial-out FAX to NetBSD or FreeBSD.
	5.3.4        What is the trick for getting Kermit to work with rz and
		     sz? 
	5.4          Tape Drives
	5.4.1        Does the tape need to be formatted?
	5.4.2        If I execute the command 'st -f /dev/st0 status', I get:
		     Archive/Tandberg? tape drive, residual=0, blocksize=512
		     Density: high = 16 (0x10), medium = 15 (0xf), low = 5
		     (0x5) ds=0 er=0 
	5.4.3        When is erst0 used?
	5.4.4        How is density (bpi) computed? I am using 3M DC 6250
		     cassettes which have a 250MB capacity on the Viper 150.
		     But computing the bits/inch based on 250MB/tape-length
		     (1020 ft.), I get a density of 171335 bpi, which is
		     nowhere near the 10000 bpi associated with QIC-150 in
		     the st(1) man page. Why the discrepancy? 
	5.4.5        How is an appropriate block size determined (and in what
		     units are they specified in the st(1) command)? 
	5.4.6        From the 4.3BSD mtio(4) man page, it sounds like data is
		     typically (traditionally?) stored on tape in
		     eof-terminated sequences of 1K records. 
	5.4.6.1      Is st's notion of "file" the record sequence between two
		     eof marks? 
	5.4.6.2      What about a "record"?
	5.4.6.3      Is a "record" one "block", as determined by st's
		     "blocksize" command? If not, what is the connection
		     between them? 
	5.4.6.4      Can I change the "record" size?
	5.4.6.5      When would I want a block size that is different from
		     the default? 1KB is the size of writes used by dd or
		     whatever. QIC specifies 512 byte records (well at least
		     its what people use..) Whatever you write in will be
		     broken into 512 byte sections. They must be multiples of
		     512 though. 
	5.4.7.1      How do I write several archives to a single tape? I
		     tried without success: $ st -f /dev/rst4 rewind $ tar cf
		     /dev/nst4 archive1 $ st -f /dev/nrst4 weof $ tar cf
		     /dev/nst4 archive2 $ st -f /dev/nrst4 weof 
	5.4.7.2      Later, I would expect to be able to access, say,
		     archive3 via the fsf directive to skip over the first
		     two archives. What is the correct sequence? 
	5.4.8        Since the Viper 150 writes on QIC-150/120, I guess I
		     don't need to worry about writing variable-length
		     records? How about reading a tape written with
		     variable-length records. Is this possible with the
		     Viper? If so, what's involved? 
	5.4.9        The very scant documentation that came with my drive
		     mentions a "selectable buffer disconnect size," whose
		     default is 16K. This is evidently the "maximum number of
		     bytes that can be sent over the SCSI bus during a single
		     data transfer phase." What's that? How is it connected
		     st's "blocksize" command? Do I want to use 16K blocks,
		     or might I even want to set the disconnect size to a
		     higher value? 
	5.4.10       What is "streaming"? When I tar a directory of files to
		     tape, I notice that the tape often stops. Streaming
		     means it doesn't stop? How would I get the viper 150 to
		     stream using tar or cpio or dump? 
	5.4.13       My tape drive doesn't work.
	5.4.14       I am trying to restore a tape from a FreeBSD machine on
		     a Sun. What kinds of problems should I expect? 
	5.4.15       What are the jumper settings for the Archive Viper tape
		     drive? 
	5.4.16       My Viper-150 auto-detects fine; however, the first
		     attempt to read a tape fails after a boot due to an
		     "illegal SCSI command". What could be the problem? 
	5.4.17       Why haven't we changed the defaults in rdump and
		     rrestore to something that makes sense? I was trying to
		     dump a filesystem to a remote tape and ran into an error
		     complaining about being unable to execute /etc/rmt. 
	5.5          Network Stuff
	5.5.1        How can I get my system to work as a network router?
	5.5.2        I recently had a problem where I got a message that said
		     "panic: kmem_malloc: mb_map too small". What is the
		     solution to this problem? 
	5.5.3        Does anyone have an example of a working gated.conf
		     file? I can't figure these instructions out at all. 
	5.5.4        How do I set up Multicasting on my system?
	5.6          I want to use my ZIP drive. Are there any weird things I
		     need to know? 
	6.0          Working with DOS and BNR/2 related software.
	6.1          Formatting a floppy
	6.2          Sharing the Disk with MS-DOS
	6.2.1        How can I partition my drive to support both MS-DOS and
		     *bsd? 
	6.2.2        I can install using the whole disk, but I can't install
		     when I try to share the drive between *BSD and MS-DOS.
		     Why? 
	6.2.4        Is there any hope of ever running MS-DOS applications
		     under any of the free BSD systems? 
	6.2.5        How do I get Linux executables to run under NetBSD?
	6.3          Accessing the MS-DOS filesystem
	6.4          NFS/PC-NFS support
	6.4.1        Can I use 8K packets for NFS? When I try, I have all
		     kinds of problems. Specifically, I get 'ring buffer
		     overflows' or the performance is real bad. 
	6.4.2        How do I get around the NFS "Permission denied" error? 
	6.4.3        What does the message "BAD MNT RPC: RPC Authentication
		     error; why = Invalid client credential" mean when I try
		     to mount something from another machine? 
	6.4.4        What does the message "Bad MNT RPC: RPC: Authentication
		     error; why = Client credential too weak" mean when I try
		     to mount something from another machine? 
	6.4.5        I get a lot of 'ring buffer overflow' messages using NFS
		     and the ed0 driver. Is there a problem? 
	6.4.6        I am getting really poor performance out of my network,
		     especially when talking to older networks or when
		     performing short file transfers. What's the problem? 
	6.4.7        Is there any PC software that will allow me to use my
		     enormous PC with all of the unsupported hardware as a
		     PC-NFS server? 
	6.5          How can I use mtools with the 'new' floppy naming
		     convention? 
	7.0          Communications
	7.1          SLIP/CSLIP
	7.2          PPP
	7.2.1        I have a problem with my PPP connection. From time to
		     time, the connection will just 'pause'. If I do
		     something in another window which polls some other

		     while. 
	7.3          TCP/IP
	7.3.1        Where can I obtain *BSD source code to add IP Security

		     FreeBSD? OpenBSD? 
	7.8.1        Is it possible to Network boot a NetBSD machine from a
		     network on a diskless Sparc? 
	7.8.2        I have been working with FreeBSD 1.5.1 with some

		     for 2.0R (i.e., Which are the magic words to put in the
		     Kernel configuration file?) 
	7.8.3        How can I get ISDN to work?
	8.0          What hardware works!
	8.3.1        How do I configure multiport cards? Is there a
		     possibility of using multiport serial boards? How do you
		     configure an AST/4 in the kernel? It looks like the AST
		     driver only supports 4-port cards, but it looks like it

0.1	A brief history of the *BSD family.

	In the beginning, there was Research Unix.  Bell Labs, in a
	moment of utter abandon said "Let us produce progeny of Unix.
	yea verily, that we might garner a market share with this white
	elephant."  In order to beget as many pretenders to the Unix
	throne as possible, they removed most of the copyright notices
	and released huge gobbets of code to Universities throughout the
	United States.  From that humble decision came the very spark of
	what has arguably become the most successful, completely free
	Unix-style operating system you can make money on.

	There were several version of BSD roaming around, but they all
	had one thing in common.  You HAD to have a source code license
	to the original Unix source to get a working version going.  The
	bulk of the code was written at Berkeley, much of it by
	long-haired computer geeks, complete with bad complexions and
	pocket protectors.  Many Master's Degrees were built on what was
	to follow.

	Then, suddenly, someone realized the amount of source code from
	the original Unix distribution was pretty much down to zilch.
	They decided that making the distribution available to the whole
	world (not just the select Unix license holders) seemed like a
	pretty 'groovy' (to use the vernacular) idea.  From that came
	the Net distribution.

	William and Lynne Jolitz, with their standard flair and panache,
	decided to write the pieces that needed to be written.  From
	that decision came 386BSD Version 0.0.  Generally considered to
	be unusable, it was nonetheless a major coup, in that one no
	longer needed the dreaded 'source license' to produce working
	operating system images.  Version 0.1 (generally considered to
	be the progenitor of all of the subsequent PC BSD systems) was
	released on Bastille Day, 1992.

	386BSD 0.1 eventually came to be.  Linux, the other entrant in
	the Free Unix-style OS family, had been running for about a year
	by then.  Many people, wanting to stick with code that they
	already knew and which was in use in the commercial sector,
	decided to start using (and fixing) the 386BSD 0.1 code.  As such,
	many contributions to the system are provided through interaction
	by people who communicate via many means.  Many new and innovative
	features have been added to 386BSD since it's original release in 
	July of '92.  There was an 'unofficial' patchkit which was available
	from many anonymous FTP sources which made 386BSD more stable and
	usable.  Many problems associated with the use of 386BSD Version 
	0.1 were solved through the application of patches from the 
	patchkit.  Now, more or less overcome by events, the original
	386BSD, with its relationship to the AT&T/Berkeley out-of-court
	settlement, has become a rare piece of code to find.  With some
	of the code considered 'suspect', it was removed from FTP sites
	world-wide.

	To replace the original 386BSD, three newer versions of the 
	system are available, under new names.  NetBSD is the oldest, 
	FreeBSD followed shortly thereafter.  Both systems have evolved 
	into programs that are superior to their progenitor and both 
	have sizable (if a little rabid) followings.  The third entry in
	the group is a fairly recent entrant, called OpenBSD.  

	Most of the statements made in this FAQ will apply to all three 
	of the replacement systems, although I will try to differentiate 
	one from another whenever the difference matters.  Any place 
	that says 386bsd either means the original 386bsd 0.1 or any 
	of the members of the PC BSD family.  

	There have been many attempts to polarize the *BSD development 
	groups in the past.  One of the reasons that I am still 
	maintaining the FAQ is that it simply is a good source for
	historical information, as well as a reasonable source for 
	information that is specific to the implementations of NetBSD, 
	FreeBSD, and OpenBSD.

	It should be remembered that when the *BSD family started out, Bill
	and Lynne used a source called the "Berkeley Net Release/2" tape 
	as their foundation.  While this provided a stable starting point, 
	it also built a possible bomb into the system.  Due to a legal 
	battle (which has now been resolved) the following files are 
	identified as 'encumbered' in the BNR/2 source tree.  These
	kernel files are identified as the 'binary only' files in the
	BSDI distribution, and either have been or must be replaced
	before we can have a truly free OS family.  These files are the
	primary reason you won't find the original 386BSD Version 0.1
	available for FTP anymore.


0.1.1	How close is NetBSD (or FreeBSD) to BSD 4.4?

	If you take a look at the README files that accompany each of
	these packages, you will find that each is based as closely as
	possible to BSD 4.4-Lite.  The core development team for FreeBSD 
	used the 4.4 Lite distribution and re-engineered the missing 
	pieces to come up with the the current version of FreeBSD.  The
	NetBSD developers started with the existing 386BSD files, and
	compared them to the unencumbered, freely releasable files from
	BSD 4.4.  For both groups, any files which were not available
	(through being encumbered) were written from scratch to provide
	the functionality that was needed.  Either way, both systems are
	close to BSD 4.4.  Of course, each has differences that make it
	different from the other, and different from regular BSD 4.4.  


0.1.3	Where can I get more information about the *BSD family of
	Operating Systems?

	Here are the current members of the *BSD family.  These are
	presented in alphabetical order, to avoid implying anything.

	386BSD - An older version of BSD now targeted exclusively at 
	the research and academic community.  CD distributions only, 
	sold by Dr. Dobb's Journal.

	FreeBSD - A version of BSD for Intel platforms only and targeted 
	at a broad user base.  See http://www.freebsd.org for details or 
	ftp://ftp.freebsd.org/pub/FreeBSD for the latest release.

	NetBSD - A version of BSD for many different platforms, from 
	Intel to the 68K to the DEC ALPHA.  See http://www.netbsd.org for 
	more details or ftp://ftp.netbsd.org/pub/NetBSD for the latest 
	release.

	OpenBSD - Another version of BSD.  See http://www.openbsd.org for 
	more details or ftp://ftp.openbsd.org/pub/OpenBSD for the latest 
	release.


0.2	About this FAQ.

	This FAQ consists of several parts:

		Section 0.  Basic FAQ information
		Section 1.  General Network Information
		Section 2.  Common installation questions
		Section 3.  Kernel Building and Maintenance
		Section 4.  Kernel Additions
		Section 5.  Kernel Replacement Parts
		Section 6.  Interaction with MS-DOS
		Section 7.  System Communication
		Section 8.  NetBSD for the Mac FAQ
		Section 9.  NetBSD for the Amiga FAQ
		...
		Section n.  NetBSD for the Timex Sinclair FAQ

	It has been suggested that I remove some of the older, less 
	relevant information from this FAQ.  I have given it some 
	thought, and I might.  Of course, if someone were to do it for 
	me, it sure wouldn't break my heart.


0.2.1	I want to start up a thread about why *BSD is or isn't as good 
	as some other operating system.  Can anyone suggest a good reason
	why I shouldn't?

	Jordan Hubbard, one of the FreeBSD core team members, has
	offered this missive on that very subject:

	[ Note:  You could very well simply substitute the word
	"NetBSD", "OpenBSD", or "Windows 95"  for "Linux" in the 
	argument that follows ]

	From time to time, a thread in both the comp.os.386bsd.misc and 
	comp.os.linux.misc groups flares up regarding which operating
	system is "better", FreeBSD or Linux.  This generally provokes 
	controversy from users on both sides, with one group claiming
	that their OS is "better" for some reason and the other group
	claiming that the first group doesn't know what the heck it's
	talking about.

	Both arguments are a waste of time.

	Rather than trying to win a rather questionable debate on
	relative (and constantly changing) technical merits, we should
	be asking ourselves what both groups are REALLY about and what
	they represent.  This is naturally going to be a matter of
	personal opinion, but I believe even the most seriously at-odds
	members would agree that both operating systems represent a
	unique and long-awaited opportunity: The ability to run a fully 
	featured operating system on popular, easily affordable
	hardware and for which all source code is freely available.
	Those who have been in computing for awhile will remember when
	the term `operating system' referred almost exclusively to
	something provided solely by the hardware vendor, with very
	little in the way of alternative options.  It was never EVER
	given out with source code, and true "wizard" status could only
	be achieved by exerting mind-numbing amounts of effort and
	patience in digging through forbidden bits of binary data.  By 
	comparison, the situation today seems almost too good to be
	true!  Certainly, the feeling of achievement that came from
	finally ferreting out some esoteric bit of information from a
	4MB printed system dump was high, but I don't think that anyone
	would argue that it was hardly the most optimal way of truly
	getting to know your operating system! :-)

	So now, within a very short space of time, we're almost spoiled
	for choice in having machines several times more powerful than
	the first multi-user VAX machines and available for under
	$2000, and we've got not one but SEVERAL perfectly reasonable
	free operating systems to chose from.  We are in a comparative 
	paradise, and what are some of us doing?  *Complaining* about 
	it!  I suppose too much is never enough, eh? :-)

	So, my essential point is simply this:  For the first time ever
	we have what previous computing generations could only dream
	about; powerful computers at a reasonable prices and a
	wonderful selection of things to run on them.  Be happy, read
	the source code you're so privileged to now have available
	(*believe* me!  What I wouldn't have given, even 5 years ago!)
	and spend your energy in making constructive use of it, not in 
	arguing with the guys on the other side of the fence!

	Additionally, it should be said that none of the FreeBSD team
	has anything but the highest degree of respect for Linus
	Torvalds and his "team" of dedicated volunteers (and we
	occasionaly exchange gripe mail about the huge volume of
	messages each of us gets as a direct result of being insane
	enough to volunteer to do something like this :-).  Our common 
	commitment to the Intel platform also gives us more common
	ground (and interests) than one might think and, if anything,
	it's a pity that we do not endeavor to share more code and
	effort - ideologically, at least, I'd say we share pretty
	similar goals.

	As to which is "best", I have only one standard reply: Try them
	both, see for yourself, think for yourself.  Both groups have
	given you something for free, at considerable personal effort,
	and the least you can do is give them the benefit of exerting
	enough effort to try what they're offering out before passing 
	judgment (or worse, blindly accepting someone else's!).

	Whichever you run, you're getting a great deal - enjoy!

0.4	How to add your pet answer to the FAQ.

	This is the trickiest part of this section of the FAQ.  There are 
	only two criteria for getting an entry made into the FAQ:

	1.  Your answer should answer a question that seems to come up
	    with some regularity, or at least perplexes a group of
	    people from time to time.

	2.  Your answer should be technically correct.  In other words,
	    answers like 'RTFM' and 'everybody knows that' are not really
	    good candidates for the FAQ.  These answers should spell out,
	    in a reasonable level of detail, precisely how to fix the
	    the question asked, or explain the basis for the answer and
	    leave the implementation of the answer to the questioner.

	All answers MUST include a question.  This is not as obvious as 
	it would seem at first glance.  An answer could solve many 
	problems, especially in the realms of system halts or other 
	catastrophes. 

	Since I (Dave) am no Unix guru, I rely HEAVILY on the input of 
	other people to make the FAQ a success.  Many questions in the 
	FAQ have been made largely irrelevant through the patchkits, but 
	that doesn't means they may not reappear.  That is why the old 
	FAQ questions are still here.

	New FAQ questions should be added.  I will try to attribute the 
	question/answer to the author, but I personally think this is a 
	waste of good disk space.  As long as the answers get out, that 
	should be reward enough :-)


0.5	Administrivia.

	Send all question/answer pairs to burgess@cynjut.neonramp.com,  
	If you are going to post the Q/A to the net, then do that, but 
	be sure to mark it as a FAQ entry.  I will get it from the net 
	as easily as I do my E-Mail.  Your Q/A will be formatted to 
	look more or less like the others and be added.  Corrections, 
	deletions, flames, snivels, and whines should be addressed 
	directly to me here.  Either way, I will be sure to send out a 
	reply letting you know what I have done with your submission.

	One last thing.  I will assume that I am infalible. :-)  I will 
	not notice any mistakes that you may find.  If you find a 
	mistake and don't tell me, it will very likely stay a mistake.
	After all, if I didn't notice it before, why should I notice
	it now?


0.6	Does anyone reading this have any sense of humor at all?

	I'm not sure.  While reasearching the great 'Linux vs. everyone
	else sucks' debate, I received this in E-Mail.  The author's
	identity has been removed to protect him from the mail-bombs.
	For the humor impaired, stop reading now!

	----------------------------------------------------------------

	Many people ask the question "Which is better?  FreeBSD, NetBSD, 
	OpenBSD, or Linux?"  Up until now, not many people are willing 
	to answer thoroughly and give reasons.  I, being a brave soul, 
	am.  This mini-FAQ lists the most significant differences 
	between Linux, NetBSD, and FreeBSD in a fair and evenhanded 
	manner.  Permission is given to redistribute this mini-FAQ 
	freely, with attribution.  If anyone wants to take the burden 
	of posting it periodically on the appropriate newsgroups, be 
	my guest.

	This is based on a message I wrote some months ago.  I've 
	tried to update it substantially to reflect the changing 
	nature of x86 OS's.

	-------------
	Q) Which is better?  NetBSD, OpenBSD, Linux, or FreeBSD?


	A) NetBSD is the best of the three because of it's superb 
	error handling capabilities (this is the "Net" referred to 
	in the name).  With NetBSD, it's almost impossible to make 
	a mistake, either in installation, or operation, because the 
	system will "catch" you as you "fall".  NetBSD works on a 
	wide range of processors, including the Intel 386, 486, and 
	586, the Sun, Sparc, SGI, MIPS, Macintosh, Motorola 6809, 
	Krupf, ADC Kentrox, Whirlpool, Amana, Zilog Z80, 
	Timex-Sinclair, and the Braun.  Currently, the NetBSD team 
	is devoting all of their energies towards finishing the 
	all-important IBM RT port.


	Linux is the successor to an operating system called "Minix".  
	Linux was developed by Linus Pauling, a Finnish communist.  
	Linux tries to uphold traditional Marxist values in several 
	ways; firstly by using GNU tools from the FSF foundation 
	wherever possible.  The Linux kernel is developed by committee, 
	and the operating system reflects this:  rather than having one 
	"init" process which fathers all others, a group of co-resident 
	processes with equal powers are created simultaneously.  "Kill" 
	commands are treated as formal protests.  Linux networking has 
	come a long way since it's implementation, and there is no truth 
	whatsoever to the rumor that sudden losses of IP connectivity 
	are in any way related to future plans to limit users to 1.5 
	hours of SLIP or PPP unless they send in the registration fee.


	FreeBSD was a radical offshoot of the Linux project; you could 
	consider it to be of the Trotskyite school.  FreeBSD supports 
	an extremely wide range of PC hardware, as long as it was 
	obtained at less than cost.  FreeBSD is used by Amnesty 
	International and many other human rights organizations.  
	FreeBSD supports every peripheral available for the IBM PC 
	except the ones you have.  The FreeBSD team was actually 
	responsible for porting  "Doom" to Linux, in a successful 
	effort to slow down constructive work by distracting the 
	central committee with frivolous games.  FreeBSD has the 
	nicest installation of any of the x86 unices -- you install 
	the boot disks, which then initialize the modem and call 
	Jordan "Perky" Hubbard, who then comes to your house with the 
	rest of the disks and completes the installation.  The FreeBSD 
	CD-ROM plays various Nick Cave and Tom Waits songs Jordan is
	known to be fond of.

	386bsd was written by Bill Jolitz in a fit of pique.  It was 
	based entirely on Sun's widely-respected "Solaris" operating 
	system, as revenge against Sun's Bill Joy, who rudely chose a 
	name with the same initials as Jolitz.  A new version of 386bsd 
	will be released very soon.  Unfortunately, it will only run on 
	386es, and thus is unsuitable for anyone with a 486 or Pentium.  
	486bsd should be released "sometime in 2138," according to 
	industry insider James Monroe, Sr.

	DID YOU KNOW?
	=============

	1) The Free and Net BSD teams split up in the year 1632.  The 
	cause of the split is uncertain, but it seems to have something 
	to do with someone named "Janice."  They still get together for 
	drinks occasionally, and remember old times.  Every so often, 
	after tying on a few too many, they end up waking up next to 
	each other and feel ashamed over their night of pleasure.  The 
	kids still blame themselves.

	2) The Linux kernel has actually not changed at all since January, 
	'94?   Linus just increments "version.c" once every 48 hours and 
	unleashes the "change" on an unsuspecting Internet, bringing FTP 
	servers to their knees.  A book, "The Design and Implementation 
	of the Linux Operating System," by Gary Marshall James T. Kirk 
	McUsenet, was rejected by Addison-Wesley on the grounds that they 
	didn't feel the public was prepared to purchase a book written 
	on looseleaf paper with diagrams in crayon.

	3) All three systems claim to be "POSIX" compliant.  However, the 
	POSIX people have denied knowing anything about it.  Scuttlebutt 
	in the industry is that POSIX will soon be outdated, and will be 
	replaced by GNOPIX, a FSF standard which implements the TOPS-20 
	operating system in Scheme.
