-OpenBSD New User FAQ Version .2 by Jonathan Katz: jkatz@openbsd.org
-
-These are a few of the questions that seem to be asked every so-often on
-the mailing list. This is very early in the making for such a document, so
-if it doesn't contain what you are looking for, please ask and feel free
-to contribute. This document DOES NOT cover the installation process.
-
-Sections:
-
-1) Non-standard hardware OR "I can't get my hardware to work."
-2) Virtual Consoles
-3) How to compile a kernel
-4) Getting source code
-5) Rebuilding my system
-6) Ethernet quirks
-7) Problems loading X11 (XFree86)
-8) Finding other software (ports).
-9) Where do I get my OpenBSD 2.1 CD?
-10) disklabel and fdisk
-11) Miscellany (HELP!)
-
--------------------------------------------------------
-
-1) My foobar 1230 SCSI adapter (or other peripheral) has a non-standard
-irq and doesn't work with the GENERIC or INSTALL kernels!
-
-Yes it does. With a little tinkering and patience, anything can be
-accomplished. At the OpenBSD boot prompt type "-c". IT should look
-something like this:
-
-[OpenBSD boot Rev. 1.0a]
-boot>> -c
-
-You will eventually get a 'UKC>' prompt. Here you can type "list" and list
-all the devices that are compiled into this kernel. Once you find the name
-of the device you'd like to change, type "change devicename". UKC will guide
-you through the different attributes of the device that can be configured.
-Once you are finished adding the necessary configurations, you'll be back at
-the UKC> prompt. At the prompt type "quit" and your machine will continue to
-boot, with the updated info.
-
-2) How do I get virtual consoles?
-
-To start, virtual consoles are only supported on the i386 port. The
-default GENERIC kernel (the one you normally get after doing an install)
-has support for virtual consoles compiled in. If you are using an
-older GENERIC kernel, or a different kernel, support for "vt0" (the
-kernel device that controls virtual consoles) may not be included. If
-you are using the 2.1 release GENERIC kernel, you will have virtual
-consoles enabled.
-
-2.1) Now that I know I have virtual consoles, how do I use them?
-
-Unlike Linux, you need to hit cntrl+alt+fn to swap from console to
-console. By default (with the files in /dev from your install, and a newly
-compiled kernel with vt0 support) you have four (F1 through F4) virtual
-consoles. If you make more ttyC devices in /dev (cd /dev; MAKEDEV ttyC4;
-MAKEDEV ttyC5; MAKEDEV ttyC6; MAKEDEV ttyC7;) and edit /etc/ttys so that
-all the tty's are on, you will have a standard 8 virtual consoles.
-
-3) How do I compile a kernel?
-
-Kernels can be compiled in under 9 steps (WOW!)
-1) get the source code VIA FTP, CTM, or CVS (skip to CVS section if need be)
-2) cd /usr/src/sys/arch/(your_machine_type)/conf
- NOTE: (your_machine_type) will vary with what kind of
- processor you use. On my VAX 3400, it would be:
- /usr/src/sys/arch/vax/conf
- On my P5/100 it would be:
- /usr/src/sys/arch/i386/conf
- On my Sparc IPC it would be:
- /usr/src/sys/arch/sparc/conf
-3) edit a config file to your liking and save it as a new name.
- (vi GENERIC; :w NEW_KERNEL_NAME :q)
- Things to keep in mind:
- Make your kernel name snazzy (you don't HAVE to do that).
- Most people keep their kernel names in caps (general
- convention).
-4) type "config NEW_KERNEL_NAME"
- If all goes according to plan it will tell you to
- "don't forget to make depend!" If config chokes on
- your file, look at what it says and play with your
- configuration until you get it right.
-5) cd /usr/src/sys/arch/(your_machine_type)/compile/NEW_KERNEL_NAME
- NOTE: config makes that DIRECTORY "NEW_KERNEL_NAME" all by
- itself.
-6) make depend ; make
-7) su (if not root already); cp /bsd /bsd.old; cp bsd /bsd
-8) shutdown/reboot your system.
-9) Enjoy your custom kernel :-)
-
-4) How do I get source code?
-
-OpenBSD source code is obtained VIA CVS, FTP or CTM. If you've ftp'd the
-distribution of OpenBSD, it should be pretty simple for you to figure out
-how to FTP the source. CTM is covered in its own document on the WWW
-server. As for CVS, here is your crash course. I've found that getting
-code VIA CVS is fast, easy, and means you get newer/better/bugfixed code.
-
-NOTE: For example purposes I'm using anoncvs.openbsd.org which is a few
-miles of fiber away from me in the United States. You may want to pick a
-nearer cvs site for you to use (especially if you are downloading the
-tree, as downloading OpenBSD's powerful crypto from the States to sites in
-Europe breaks various laws). See the OpenBSD WWW sites for a cvs mirror
-close to home. If these instructions are not working for you, please skip
-to the section that talks about the "pserver" that has been set-up in
-order to aleviate the headache of a proxy/firewall that may be causing you
-some greif.
-
-INITIAL USE:
-cd /usr
-setenv CVSROOT anoncvs@anoncvs.openbsd.org:/cvs
-cvs -z 9 -q get -PA src
-
-UPDATE USE:
-cd /usr/src
-setenv CVSROOT anoncvs@anoncvs.openbsd.org:/cvs
-cvs -z 9 -q up -PAd
-
-"pserver" WORK-AROUND:
-cd /usr
-setenv CVSROOT :pserver:anoncvs@anoncvs5.usa.openbsd.org:/cvs
-cvs login
-<type any password, it will return ok...work>
-cvs -z9 -q get src ..
-
-[From: Todd Miller... millert@openbsd.org]
-
-A quick explanation of the flags:
-"-z 9" turns on compression-- the same as "gzip -9"
-"-q" makes it quiet, as CVS can generate a lot of output
-"-d" will create and update new directories if your tree does not have
- them
-"-P" prunes out old directories
-"-A" resets sticky tags
-
-5) How do I rebuild my system?
-
-Depending on what version system you have and what version source you
-have, it can be as easy as four steps, and as legnthy as 22. If
-you have a 2.1 CD (or downloaded 2.1) and are using "-current"
-sources, you should be able to recompile in 4 steps. In order to get 2.1
-(and later) versions to compile on a 2.0 based system, things get a little
-tricky.
-
-5.1) "The Four Steps" (as opposed to the Four Questions)
-
-If you want to be risky, you can just try doing a "make -k build" in
-/usr/src-- the four steps below follow a prudent guideline for making
-a new system.
-
-1) cd /usr/src/share/mk; make install
-2) mkdir /usr/obj; cd /usr/src; make obj
-3) make -k build && make install
-4) make cleandir
-
-A quick explanation:
-1) "fixes" Makefiles and make (if broken, which somestimes happens)
-2) makes the directory for objects, then makes the objects
-3) builds the entire system. "-k" is a flag to make that tries to have
- make progress if there are any errors. "make build" also builds
- the dependencies. "make install" makes SURE it gets installed--
- "make build" is supposed to do the installing.
-4) this cleans up the source tree (deletes out extra binaries, etc)
-
-5.2) The long version. These are very detailed instructions given to
-misc@openbsd.org from Marco Hyman. If you aren't too paranoid, you can
-actually skip some of the stuff in there, at your own risk. Please read
-through carefully. If you aren't careful, you can actually hose your
-system up :(

-From marc@dumbcat.codewright.com Sun May 4 17:57:34 1997
-Date: Sat, 03 May 1997 12:10:35 -0700
-From: Marco S Hyman <marc@dumbcat.codewright.com>
-To: tech@openbsd.org, misc@openbsd.org
-Subject: From 2.0 to current in 22 steps
-
-Someone (Theo?) recently said that updating from a 2.0 to current was
-a bitch. That sounded enough like a challenge that I thought I'd try
-it -- and document what I had to do at the same time. Hope this is
-helpful to others.
-
-Given:
- o System running 2.0 code
- o -current source tree mounted as /usr/src. My -current source lives on a
- different host, so it happens to be NFS mounted. This code was current
- as of 1 May.
- o An empty /usr/obj on the local disk.
-
-Variables:
-
- * $arch=i386, the architecture I'm generating the code for
- * $config=TRAVEL, my configuration file. This is a copy of ALL with
- everything I don't use commented out and a few minor changes. Travel
- is a Toshiba laptop and I wanted the PCMCIA modem to be com1 and the
- PCMCIA ethernet card to be either ed0 or ep0, depending upon which
- flavor or card I happen to be using.
-
-Ok, here are the steps. Disclaimer mode:
- - Some may not be necessary.
- - There may be necessary steps that I missed and just luckely
- have not run into problems yet.
- - The order that I did things may be wrong.
- - Etc.
-[ FAQ assembler's note: This mailing was hearlded by some as a masterpiece
-rivaling the Magna Carta :) ]
-
- [ 1] cd /usr/src/share/mk && make install
- use the new make for everything
-
- [ 2] cd /usr/src/includes && make includes
- use the new included for everything
-
- [ 3] cd /usr/src/bin/pdksh && make && make install && make clean
- This is installed as /bin/sh which is needed for the next step.
- The 2.0 /bin/sh does not work with making the object links.
- The `make clean' step is to get the $arch specific objects
- out of the source directory.
-
- [ 4] cd /usr/src && make obj
- make the obj links so that code is generated on the local disk,
- not the NFS mounted source disk. (Note: the kernel is still
- generated in /sys/arch/$arch/compile/$config).
-
- [ 5] cd /usr/src/usr.bin/mktemp && make && make install
- mktemp is required to generate a kernel
-
- [ 6] cd /usr/src/usr.sbin/config && make depend && make && make install
- The latest config MUST be used to generate the new kernel. If you
- don't use this config you won't get past the "make depend" step
- of kernel generation.
-
- [ 7] cd /sys/arch/$arch/conf
- edit your $config file if necessary.
-
- [ 8] config $config
- generate required files to build updated kernel.
-
- [ 9] cd ../compile/$config && make clean && make depend && make
- Don't forget the make clean. It may not be necessary, but doesn't
- hurt in any case. The new config may have even warned you to do
- this.
-
- [10] mv /bsd /bsd- && mv bsd /
- Get ready...
-
- [11] reboot
- Reboot your box and watch the console to see what's going on. In
- my case all went well. Xdm started and gave me my console login.
- I ssh'd from another host, su'd, and then re-mounted the current
- source on /usr/src. uname -a says:
-
- OpenBSD travel.codewright.com 2.1 TRAVEL#0 i386
-
- [12] cd /usr/src && make cleandir
- We start with this step of the build process because the
- /usr/src/share/mk and the include files were installed above.
-
- [13] cd /usr/src/usr.bin/compile_et && make depend && make && make install
- this tool is required to build the libraries.
-
- [14] cd /usr/src/usr.bin/mk_cmds && make depend && make && make install
- this tool is required to build the libraries
-
- [15] cd /usr/src/lib && make depend && make && make install
- Go and have dinner then see a movie. This should be done
- just about the time you get back to the console. At least
- that's how long it takes on my old pentium portable.
-
- [16] cd /usr/src/gnu/usr.bin/ld && make depend && make && make install
- needed for the gnu libraries (libg++ will fail)
-
- [17] cd /usr/src/gnu/lib && make depend && make && make install
-
- [18] cd /usr/src/kerberosIV && make build
-
- [19] cd /usr/src/gnu/usr.bin/texinfo && \
- make -f Makefile.bsd-wrapper && \
- make -f Makefile.bsd-wrapper install
- The updated makeinfo is required by gcc which is generated
- before makeinfo when doing a standard `make'
-
- [20] cd /usr/src && make depend && make && make install
-
- [21] reboot
- See that everything comes up. If your source lives on a
- remote machine (like mine does), mount it on /usr/src.
-
- [22] cd /usr/src && make build
- This step is optional. I like to use the generated system to
- regenerate the full system just to ensure that all is OK.
- Probably best to start this before you go to bed. It might
- be done by the time you wake up.
-
-As I type this I've completed steps 1-21. Step 22 is in progress. I'll
-mail out an update if I run into any problems. Again, I hope this is
-helpful to others.

-There you have it!
-
-6) Why can't I use my old linux ifconfig commands and flags?
-
-Linux's implementations of "ifconfig" and "route" are not standard.
-OpenBSD's versions are normal. To get my ne2000 clone working, I type:
-
-corinne# ifconfig ed2 205.212.82.80 up
-corinne# route add default 205.212.82.1
-
-That should work to get ANY ethernet interface working, as long as you
-specify the correct IP numbers and interface.
-
-6.1) Whenever I do anything to the network I get a "device timeout"
- error!?!
-
-This is because you have an incorrect hardware or irq address assigned to
-your ethernet interface. To fix this, reboot the machine with the "-c"
-flag and change the attributes for your ethernet interface. See the
-general instructions in item 1 of this FAQ on how to change how the
-kernel talks to your hardware.
-
-6.2) Hey, my IP Aliasing breaks after trying to add a third host!
-
-Aliasing one additional host usually isn't a big deal. When a user tries
-to alias a third or fourth host, sometimes things break. Adding
-"netmask 0xffffffff" to the end of your "ifconfig" for adding the aliased
-host solves the problem. i.e.:
-
-sparcy# ifconfig le0 alias 123.45.67.89 netmask 0xffffffff
-
-7) Why won't XFree86 load on my (insert really cool/expensive, you
-know-it-will-work-because-you-checked-it-on-the-compatability-list at
-xfree86.org) graphics card?
-
-Some of the X servers require direct access to "/dev/mem" (raw memory)
-in order to work. By default, the OpenBSD kernel does not allow for this.
-There are two solutions:
- A) recompile a kernel with "option insecure" in your configuration
- file.
- B) Use the "apature" Loadable Kernel Module (lkm) found in the X11
- distribution.
-
-8) Where's pine (or other GNU/semi-free utility)?
-
-All about ports (as cribbed from www.openbsd.org/ports.html)
-
-OpenBSD is a fairly complete system of its own, but there still is a lot
-of software that one might want see added to their own system. However,
-one has to draw the line on what to include and leave out, as well as
-having to follow licensing and export restrictions laws. Because of these
-problems, some software cannot be shipped with the system. We wanted to
-find a way for users to easily get software we don't provide and started
-to look around. We didn't have to look far because a sibling project,
-FreeBSD, has an excellent mechanism for exactly this purpose called "The
-Ports Collection". After thinking about it for a while we decided to try
-and use their collection as is, feeding back necessary patches that make
-the ports work on OpenBSD as well as FreeBSD.
-
-The ports idea is to have, for each piece of software, a Makefile that
-describes where to download it from, how to alter the sources (if needed)
-and how to build and install it. Furthermore some patches will have to be
-kept in the "port" as well as some administration files for the package
-registry utilities. Normally this information is kept in an hierarchy
-under /usr/ports (this is configurable, and can be changed). The entire
-ports tree can be found at
- ftp://ftp.freebsd.org/pub/FreeBSD/FreeBSD-current/ports.tar.gz
-
-Note that this isn't a file on their server, rather it archives their
-directories on-the-fly. The entire collection is almost 3.1M tarred and
-gzip'd and will probably be twice that when uncompressed. The ports tree
-is also on the 2.1 CD.
-
-Let's say you managed to get a ports tree sitting under /usr/ports, then
-you should be able to something like this:
-
- mitnick% su
- mitnick# cd /usr/ports/archivers/unzip
- mitnick# make
- mitnick# make install
- mitnick# exit
-
-Easy, huh?
-
-9) Where do I get my OpenBSD 2.1 CD?
-
-To preface, because OpenBSD contains powerful crypto, CDs are being
-distributed from Canda, Sweden, and Argentina. CDs cost $30 US plus
-shipping ($3-$8 US, generally). The CDs are a two CD set, complete with
-binaries for the Alpha, i386, Sparc, Amiga, Arc, Mac (68k), Pmax, and
-Motorola 68k VME systems, source code, X11R6.3, XFree86 3.3 (binaries and
-sources). In addition, The CDs are designed to be bootable on multiple
-architectures.
-
-http://www.openbsd.org/orders.html will take you through the credit card
-on-line odering system. To order VIA phone, call +1 (403) 605-8166
-between 8AM and 5PM North American Mountain Standard Time. Please
-have your American Express, Master Card or Visa ready.
-
-10) disklabel and fdisk
-
-disklabel and fdisk are different in OpenBSD than what most users are used
-to in different oprating systems. Both disklabel and fdisk are coverend
-in-depth in various install documents as well as their respective man
-pages. This portion of the FAQ is here only to explain the philosophy of
-the situation.
-
-In OpenBSD, disklabel is the core program used to modify and view a
-system's hard disk. disklabel is used to establish the disk's partitions
-as well as write the OpenBSD disklabel to disk. disklabel is also used to
-display which partitions are which. By running disklabel with an argument
-like "wd0" (think "disklabel wd0") the output will show not only what
-partitions of the disk are used by OpenBSD, but also what partitions ca be
-used to access DOS partitions.
-
-Unlike Linux, DOS, or FreeBSD, OpenBSD's fdisk is not
-full-screen/interactive. fdisk is used to manipulate partitions other than
-OpenBSD partitions as wel as the MBR on various hard disks. If you are
-sharing a disk between DOS and OpenBSD, you can change which partition is
-active with fdisk. fdisk can also be used to display the same partition
-information as disklabel, although the format of the output is different.
-
-11) XXYYZZ (system something) is broken!
-
-The OpenBSD source tree is always evolving. The 2.1 release is wonderful
-and stable; however since the release snapshots will be made with many
-bugfixes every so often. Make sure you are running the latest code before
-giving up. See the OpenBSD ftp mirrors (as listed on the OpenBSD www
-sites) as well as the CVS section on how to obtain the source. ALSO, watch
-the misc@openbsd.org and announce@openbsd.org mailing lists for vital
-information. As another resource with your problems, check the OpenBSD
-mailing list archive, where it is quite possible that your question or
-concern has already been addressed. PS: always "man (utility)" and
-"apropos (problem)" because the answer you are looking for can lurk in the
-documentation.
