The NetBSD Operating System is a fully functional Open Source UNIX-like operating system derived from the University of California, Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on many different different system architectures (ports) across a variety of distinct CPU families, and is being ported to more. The NetBSD 9.2 release contains complete binary releases for most of these system architectures, with preliminary support for the others included in source form. Please see the NetBSD website for information on them.
NetBSD is a completely integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code.
NetBSD is a creation of the members of the Internet community. Without the unique cooperation and coordination the net makes possible, NetBSD would not exist.
The NetBSD 9.2 release provides many significant changes, including support for many new devices, hundreds of bug fixes, new and updated kernel subsystems, and numerous userland enhancements. The result of these improvements is a stable operating system fit for production use that rivals most commercially available systems.
It is impossible to completely summarize the massive development that
went into the
NetBSD
9.2 release.
The complete list of changes can be found in the following files:

It now supports arbitrary big disks and offers GPT partitions as alternative to MBR/fdisk partitions on a lot architectures.
Unfortunately it has not been tested on all hardware supported by NetBSD. If you have problems partitioning the target disk or installing the system, please report bugs with as much details as possible. See the Administrivia section below on how to report bugs or contact other users and ask for support.

The root directory of the NetBSD 9.2 release is organized as follows:
.../NetBSD-9.2/
CHANGESCHANGES-9.0CHANGES-9.1CHANGES-9.2CHANGES.prevLAST_MINUTEREADME.filesimages/source/In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures for which NetBSD 9.2 has a binary distribution.
The source distribution sets can be found in subdirectories of the
source
subdirectory of the distribution tree.
They contain the complete sources to the system.
The source distribution sets are as follows:
config(1)
utility.
All the above source sets are located in the
source/sets
subdirectory of the distribution tree.
The source sets are distributed as compressed tar files.
Except for the
pkgsrc
set, which is traditionally unpacked into
/usr/pkgsrc,
all sets may be unpacked into
/usr/src
with the command:
# cd / ; tar -zxpf set_name.tgz
In each of the source distribution set directories, there are files which contain the checksums of the files in the directory:
MD5SHA512The SHA512 digest is safer, but MD5 checksums are provided so that a wider range of operating systems can check the integrity of the release files.

NetBSD maintains its own set of sources for the X Window System in order to assure tight integration and compatibility. These sources are based on XFree86 4.5.0. Binary sets for the X Window System are distributed with NetBSD. The sets are:
The sun3 binary distribution sets are distributed as gzipped tar files
named with the extension
.tgz,
e.g.
base.tgz.
The instructions given for extracting the source sets work equally
well for the binary sets, but it is worth noting that if you use that
method, the filenames stored in the sets are relative and therefore
the files are extracted
below the current directory.
Therefore, if you want to extract the binaries into your system, i.e.
replace the system binaries with them, you have to run the
tar -xzpf
command from the root directory (
/
) of your system.
There is a collection of Sun3 and Sun3X kernels in the
sun3/binary/kernels
subdirectory of the
NetBSD
9.2 distribution.
The ones named
netbsd-ramdisk*.gz
contain a root file system image and should only be used for the
initial installation.
The others are included for convenience.
(Most people will want to use
netbsd-generic.gz
or
netbsd-generic3x.gz
as appropriate.)
Please note that these kernels are simply gzipped and are not tar archives.
NetBSD/sun3 9.2 runs on most Sun3 machines, including:
| 3/50 | 3/60 | 3/110 |
| 3/75 | 3/150 | 3/160 |
| 3/260 | 3/280 | 3/E |
| 3/80 | 3/470 |
Note that NetBSD/sun3 includes support for `Sun3X' machines, which used to be supported with a separate NetBSD/sun3x distribution.
The minimal configuration requires 4 MB of RAM and about 100 MB of disk
space.
To install the entire system requires much more disk space.
To run X or compile the system, more RAM is recommended.
Good performance requires 8 MB of RAM, or 16 MB when running the
X Window System.
A good rule of thumb is to have a swap partition twice the size of the
amount of RAM in your machine.
You will probably want to compile your own kernel, as
GENERIC
is large and bulky to accommodate all people.
Note that the sun3 installation procedure uses a miniroot image which is placed into the swap area of the disk. The swap partition must be at least as large as the miniroot image (10 MB).
If it's not on this list, there is no support for it in this release.
Installation is supported from several media types, including:
The procedure for transferring the distribution sets onto installation media depends on the type of media. Instructions for each type of media are given below.
In order to create installation media, you will need all the files in the directory
.../NetBSD-9.2/sun3/
The boot tape is created as follows:
# cd .../NetBSD-9.2/sun3/installation/tapeimage
# sh MakeBootTape /dev/nrst0
The install tape is created as follows:
# cd .../NetBSD-9.2/sun3/installation/tapeimage
# sh MakeInstallTape /dev/nrst0
If the tapes do not work as expected, you may need to explicitly
set the EOF mark at the end of each tape segment.
It may also be necessary to use the
conv=osync
argument to
dd(1).
Note that
this argument is incompatible with the
bs=
argument.
Consult the tape-related manual pages on the system where the tapes are
created for more details.
If you are using a
NetBSD
system as the boot-server, have a look at
the
diskless(8)
manual page for guidelines on how to proceed with this.
If the server runs another operating system, consult the
documentation that came with it (i.e.
add_client(8)
on
SunOS).
When instructed to boot over the network, your sun3 expects to be
able to download a second stage bootstrap program via
TFTP
after
it has acquired its IP address through
RARP.
It will attempt to download a file using a name derived from the
machine's recently acquired IP address,
and in the case of sun3x machines, an extension which corresponds to the
machine architecture.
(It may be handy to have a hexadecimal
calculator for this next step.)
The filename is created by
converting the machine's assigned IP address into hexadecimal,
most-significant octet first, using uppercase characters for the
non-decimal (A-F) digits.
sun3x machines use a filename suffix of
.SUN3X.
For example, a sun3 which has been assigned IP address 130.115.144.11
will make an
TFTP
request for
8273900B,
and a sun3x will try
8273900B.SUN3X.
Normally, this file
is a symbolic link to the
NetBSD/sun3
netboot
program, which should
be located in a place where the
TFTP
daemon can find it.
(Remember, many TFTP daemons run in a chroot'ed environment.)
The netboot program may be found in the install directory of this distribution.
The netboot program will query a bootparamd server to find the
NFS server address and path name for its root, and then load a
kernel from that location.
The server should have a copy of the netbsd-rd kernel in the root area
for your client (no other files are needed in the client root) and
/etc/bootparams
on the server
should have an entry for your client and its root directory.
The client will need access to the miniroot image, which can be
provided using NFS or remote shell.
If you will be installing NetBSD on several clients, it may be useful to know that you can use a single NFS root for all the clients as long as they only use the netbsd-rd kernel. There will be no conflict between clients because the RAM-disk kernel will not use the NFS root. No swap file is needed; the RAM-disk kernel does not use that either.
.../install
(which you get via FTP).
Once you have booted netbsd-rd (the RAM-disk kernel)
and loaded the miniroot, you can load any of the distribution sets
over the net using FTP.
The
install
program in the miniroot
automates the work required to configure the network interface and
transfer the files.
The preparations for this installation/upgrade method are easy; all
you make sure that there's some FTP site from which you can retrieve
the
NetBSD
distribution when you're about to install or upgrade.
You need to know the numeric IP address of that site, and, if it's not on
a network directly connected to the machine on which you're installing
or upgrading
NetBSD,
you need to know the numeric IP address of the
router closest to the
NetBSD
machine.
Finally, you need to know the numeric IP address of the
NetBSD
machine itself.
Sun3 machines usually need little or no preparation before installing NetBSD, other than the usual, well advised precaution of backing up all data on any attached storage devices.
You will need to know the SCSI target ID of the drive on which you will install NetBSD.
sd2,
target 2 is
sd4,
etc.
It might be a good time to run the diagnostics on your Sun3.
First, attach a terminal to the
ttya
serial port, then set the
``Diag/Norm''
switch to the Diagnostic position, and power-on the machine.
The Diag. switch setting forces console interaction to occur on ttya.
Note that the 3/80 has a
``software''
diag switch you can set at
the PROM monitor prompt.
To turn on diag boot mode, do:
q 70b 12
To return to normal boot mode, do:
q 70b 6.
The console location (ttya, ttyb, or keyboard/display) is controlled
by address 0x1F in the EEPROM, which you can examine and change in
the PROM monitor by entering
q1f
followed by a numeric value (or
just a
`.'
if you don't want to change it).
Console values are:
00101120Installing NetBSD is a relatively complex process, but if you have this document in hand it should not be too difficult.
There are several ways to install NetBSD onto your disk. If your machine has a tape drive the easiest way is Installing from tape (details below). If your machine is on a network with a suitable NFS server, then Installing from NFS is the next best method. Otherwise, if you have another Sun machine running SunOS you can initialize the disk on that machine and then move the disk. (Installing from SunOS is not recommended.)
>b st()
>b st(0,8,0)
The first example will use the tape on SCSI target 4, where the
second will use SCSI target 5.
The
>
is the monitor prompt.
After the tape loads, you should see many lines of configuration messages, and then the following `welcome' screen:
Welcome to the NetBSD/sun3 RAMDISK root!
This environment is designed to do only three things:
1: Partition your disk (use the command: edlabel /dev/rsd0c)
2: Copy a miniroot image into the swap partition (/dev/rsd0b)
3: Reboot (using the swap partition, i.e. /dev/sd?b).
Note that the sun3 firmware cannot boot from a partition located
more than 1 GB from the beginning of the disk, so the swap partition
should be completely below the 1 GB boundary.
Copying the miniroot can be done several ways, allowing
the source of the miniroot image to be on any of these:
boot tape, NFS server, TFTP server, rsh server
The easiest is loading from tape, which is done as follows:
mt -f /dev/nrst0 rewind
mt -f /dev/nrst0 fsf 2
dd if=/dev/nrst0 of=/dev/rsd0b bs=32k conv=sync
(For help with other methods, please see the install notes.)
To reboot using the swap partition, first use "halt",
then at the PROM monitor prompt use a command like:
b sd(,,1) -s
To view this message again, type: cat /.welcome
Copy the miniroot as described in the welcome message, and reboot from that just installed miniroot. See the section entitled Booting the miniroot for details.
First, at the Sun PROM monitor prompt, enter a boot command using the network interface as the boot device. On desktop machines this is le, and ie on the others. Examples:
>b le() -s
>b ie() -s
After the boot program loads the RAMDISK kernel, you should see the welcome screen as shown in the Installing from tape section above. You must configure the network interface before you can use any network resources. For example the command:
ssh> ifconfig le0 inet 192.233.20.198 up
will bring up the network interface with that address. The next step is to copy the miniroot from your server. This can be done using either NFS or remote shell. (In the examples that follow, the server has IP address 192.233.20.195.) You may then need to add a default route if the server is on a different subnet:
ssh> route add default 192.233.20.255 1
You can look at the route table using:
ssh> route show
Now mount the NFS file system containing the miniroot image:
ssh> mount -r 192.233.20.195:/server/path /mnt
The procedure is simpler if you have space for an expanded (not compressed) copy of the miniroot image. In that case:
ssh> dd if=/mnt/miniroot.fs of=/dev/rsd0b bs=8k
Otherwise, you will need to use
zcat
to expand the miniroot image while copying.
This is tricky because the
ssh
program
(small shell) does not handle
sh(1)
pipeline syntax.
Instead, you first run the reader in the background with its input set
to
/dev/pipe
and then run the other program in the foreground with its output to
/dev/pipe.
The result looks like this:
ssh> run -bg dd if=/dev/pipe of=/dev/rsd0b obs=8k
ssh> run -o /dev/pipe zcat /mnt/install/miniroot.fs.gz
To load the miniroot using rsh to the server, you would use a pair of commands similar to the above. Here is another example:
ssh> run -b dd if=/dev/pipe of=/dev/rsd0b obs=8k
ssh> run -o /dev/pipe rsh 192.233.20.195 zcat miniroot.fs.gz
First, boot SunOS and place the miniroot file onto the hard drive. If you do not have gzip for SunOS, you will need to decompress the image elsewhere before you can use it.
Next, bring SunOS down to single user mode to insure that nothing will be using the swap space on your drive. To be extra safe, reboot the machine into single-user mode rather than using the shutdown command.
Now copy the miniroot image onto your swap device (here
/dev/rsd0b)
with the command
gzip -dc miniroot.fs.gz | dd of=/dev/rsd0b obs=32k
or if you have already decompressed the miniroot
dd if=miniroot.fs of=/dev/rsd0b obs=32k
Finally, reboot the machine and instruct the ROM to boot from the swap device as described in the next section.
b'
of the disk with
SCSI target ID=0 then the PROM boot command would be:
>b sd(0,0,1) -s
With SCSI target ID=2, the PROM is:
>b sd(0,10,1) -s
The numbers in parentheses above are:
The miniroot's install program will:
foo
instead of
foo.bar.org.
If, during the process of configuring
the network interfaces, you make a mistake, you will
be able to re-configure that interface by simply selecting
it for configuration again.
/etc/fstab.
/).
/dev.
/).
First-time installation on a system through a method other than the
installation program is possible, but strongly discouraged.
Once you've got the operating system running, there are a few things you need to do in order to bring the system into a properly configured state. The most important steps are described below.
postinstall(8).
/etc/rc.conf
If you or the installation software haven't done any configuration of
/etc/rc.conf
(sysinst
normally will),
the system will drop you into single user mode on first reboot with the
message
/etc/rc.conf is not configured. Multiuser boot aborted.
and with the root file system
(/)
mounted read-only.
When the system asks you to choose a shell, simply press
RETURN
to get to a
/bin/sh
prompt.
If you are asked for a terminal type, respond with
vt220
(or whatever is appropriate for your terminal type)
and press
RETURN.
You may need to type one of the following commands to get your delete key
to work properly, depending on your keyboard:
# stty erase '^h'
# stty erase '^?'
At this point, you need to configure at least
one file in the
/etc
directory.
You will need to mount your root file system read/write with:
# /sbin/mount -u -w /
Change to the
/etc
directory and take a look at the
/etc/rc.conf
file.
Modify it to your tastes, making sure that you set
rc_configured=YES
so that your changes will be enabled and a multi-user boot can
proceed.
Default values for the various programs can be found in
/etc/defaults/rc.conf,
where some in-line documentation may be found.
More complete documentation can be found in
rc.conf(5).
When you have finished editing
/etc/rc.conf,
type
exit
at the prompt to
leave the single-user shell and continue with the multi-user boot.
Other values that may need to be set in
/etc/rc.conf
for a networked environment are
hostname
and possibly
defaultroute.
You may also need to add an
ifconfig_int
for your
<int>
network interface,
along the lines of
ifconfig_le0="inet 192.0.2.123 netmask 255.255.255.0"
or, if you have
myname.my.dom
in
/etc/hosts:
ifconfig_le0="inet myname.my.dom netmask 255.255.255.0"
To enable proper hostname resolution, you will also want to add an
/etc/resolv.conf
file or (if you are feeling a little more adventurous) run
named(8).
See
resolv.conf(5)
or
named(8)
for more information.
Instead of manually configuring networking,
DHCP can be used by setting
dhcpcd=YES
in
/etc/rc.conf.
After reboot, you can log in as
root
at the login prompt.
If you didn't set a password in
sysinst,
there
is no initial password.
You should create an account for yourself (see below) and protect it and the
``root''
account with good passwords.
By default, root login from the network is disabled (even via
ssh(1)).
One way to become root over the network is to log in as a different
user that belongs to group
``wheel''
(see
group(5))
and use
su(1)
to become root.
Use the
useradd(8)
command to add accounts to your system.
Do not
edit
/etc/passwd
directly! See
vipw(8)
and
pwd_mkdb(8)
if you want to edit the password database.
If you installed the X Window System, you may want to read the chapter about X in the NetBSD Guide:
If you wish to install any of the software freely available for UNIX-like systems you are strongly advised to first check the NetBSD package system, pkgsrc. pkgsrc automatically handles any changes necessary to make the software run on NetBSD. This includes the retrieval and installation of any other packages the software may depend upon.
sun3/9.2/All
subdir.
If you installed
pkgin(1)
in the
sysinst
post-installation configuration menu, you can use it to automatically install
binary packages over the network.
Assuming that
/usr/pkg/etc/pkgin/repositories.conf
is correctly configured, you can install them with the following commands:
# pkgin install tcsh # pkgin install bash # pkgin install perl # pkgin install apache # pkgin install kde # pkgin install firefox ...
/pub/pkgsrc
directory.
The above commands will install the Tenex-csh and Bourne Again shells, the Perl programming language, Apache web server, KDE desktop environment and the Firefox web browser as well as all the packages they depend on.
pkgsrc(7)
framework for compiling packages can be obtained by
retrieving the file
/usr/pkgsrc
(though other locations work fine) with the commands:
# cd /usr
# tar -zxpf pkgsrc.tar.gz
After extracting, see the
doc/pkgsrc.txt
file in the extraction directory (e.g.,
/usr/pkgsrc/doc/pkgsrc.txt)
for more information.
/etc/mail/aliases
to forward root mail to the right place.
Don't forget to run
newaliases(1)
afterwards.
/etc/rc.local
to run any local daemons you use.
/etc
files are documented in section 5 of the manual; so just invoking
# man 5 filename
is likely to give you more information on these files.
It is possible to easily upgrade your existing NetBSD/sun3 system using the upgrade program in the miniroot. If you wish to upgrade your system by this method, simply select the upgrade option once the miniroot has booted. The upgrade program with then guide you through the procedure. The upgrade program will:

Using the miniroot's upgrade program is the preferred method of upgrading your system.
However, it is possible to upgrade your system manually. To do this, follow the following procedure:

Users upgrading from previous versions of NetBSD may wish to bear the following problems and compatibility issues in mind when upgrading to NetBSD 9.2.
Note that sysinst will automatically invoke
postinstall fix
A number of things have been removed from the NetBSD 9.2 release. See the ``Components removed from NetBSD'' section near the beginning of this document for a list.
Documentation is available if you installed the manual
distribution set.
Traditionally, the
``man pages''
(documentation) are denoted by
`name(section)'.
Some examples of this are
intro(1),
man(1),
apropos(1),
passwd(1),
and
passwd(5).
The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative information is in section 8.
The man command is used to view the documentation on a topic, and is started by entering man [section] topic. The brackets [] around the section should not be entered, but rather indicate that the section is optional. If you don't ask for a particular section, the topic with the lowest numbered section name will be displayed. For instance, after logging in, enter
# man passwd
to read the documentation for
passwd(1).
To view the documentation for
passwd(5),
enter
# man 5 passwd
instead.
If you are unsure of what man page you are looking for, enter
# apropos subject-word
where subject-word is your topic of interest; a list of possibly related man pages will be displayed.
If you've got something to say, do so!
