INSTALLATION NOTES for OpenBSD/mac68k 4.2 What is OpenBSD? ---------------- OpenBSD is a fully functional, multi-platform UN*X-like Operating System based on Berkeley Networking Release 2 (Net/2) and 4.4BSD-Lite. There are several operating systems in this family, but OpenBSD differentiates itself by putting security and correctness first. The OpenBSD team strives to achieve what is called a 'secure by default' status. This means that an OpenBSD user should feel safe that their newly installed machine will not be compromised. This 'secure by default' goal is achieved by taking a proactive stance on security. Since security flaws are essentially mistakes in design or implement- ation, the OpenBSD team puts as much importance on finding and fixing existing design flaws and implementation bugs as it does writing new code. This means that an OpenBSD system will not only be more secure, but it will be more stable. The source code for all critical system components has been checked for remote-access, local-access, denial- of-service, data destruction, and information-gathering problems. In addition to bug fixing, OpenBSD has integrated strong cryptography into the base system. A fully functional IPsec implementation is provided as well as support for common protocols such as SSL and SSH. Network filtering and monitoring tools such as packet filtering, NAT, and bridging are also standard, as well as several routing services, such as BGP and OSPF. For high performance demands, support for hardware cryptography has also been added to the base system. Because security is often seen as a tradeoff with usability, OpenBSD provides as many security options as possible to allow the user to enjoy secure computing without feeling burdened by it. To integrate more smoothly in other environments, OpenBSD 4.2 also provides, on some platforms, several binary emulation subsystems (which includes iBCS2, Linux, OSF/1, SunOS, SVR4, Solaris, and Ultrix compatibility), aiming at making the emulation as accurate as possible so that it is transparent to the user. Because OpenBSD is from Canada, the export of Cryptography pieces (such as OpenSSH, IPsec, and Kerberos) to the world is not restricted. (NOTE: OpenBSD can not be re-exported from the US once it has entered the US. Because of this, take care NOT to get the distribution from an FTP server in the US if you are outside of Canada and the US.) A comprehensive list of the improvements brought by the 4.2 release is available on the web at http://www.OpenBSD.org/42.html. OpenBSD/mac68k runs on some of the old Macintosh (Motorola 680x0-based) computers.

If you wish to become a distribution site for OpenBSD, contact . OpenBSD 4.2 Release Contents: ----------------------------- The OpenBSD 4.2 release is organized in the following way. In the .../4.2 directory, for each of the architectures having an OpenBSD 4.2 binary distribution, there is a sub-directory. The mac68k-specific portion of the OpenBSD 4.2 release is found in the "mac68k" subdirectory of the distribution. That subdirectory is laid out as follows: .../4.2/mac68k/ INSTALL.mac68k Installation notes; this file. MD5 Output of the md5(1) program, usable for verification of the correctness of downloaded files. *.tgz mac68k binary distribution sets; see below. bsd A stock GENERIC mac68k kernel which will be installed on your system during the install. bsdsbc A slightly different GENERIC mac68k kernel, using a different SCSI driver for some mac68k models, which may allow some otherwise incompatible SCSI devices to function with OpenBSD/mac68k. bsd.rd A compressed RAMDISK kernel; the embedded filesystem contains the installation tools. Used for simple installation from a pre-existing system. bsdsbc.rd A slightly different RAMDISK kernel, using a different SCSI driver for some mac68k models, which may allow some otherwise incompatible SCSI devices to function with OpenBSD/mac68k. utils/ The OpenBSD/mac68k boot program for Mac OS. The OpenBSD/mac68k binary distribution sets contain the binaries which comprise the OpenBSD 4.2 release for mac68k systems. There are eleven binary distribution sets. The binary distribution sets can be found in the "mac68k" subdirectory of the OpenBSD 4.2 distribution tree, and are as follows: base42 The OpenBSD/mac68k 4.2 base binary distribution. You MUST install this distribution set. It contains the base OpenBSD utilities that are necessary for the system to run and be minimally functional. It includes shared library support, and excludes everything described below. [ 39.3 MB gzipped, 127.4 MB uncompressed ] comp42 The OpenBSD/mac68k Compiler tools. All of the tools relating to C, C++, Objective-C and Fortran are supported. This set includes the system include files (/usr/include), the linker, the compiler tool chain, and the various system libraries (except the shared libraries, which are included as part of the base set). This set also includes the manual pages for all of the utilities it contains, as well as the system call and library manual pages. [ 46.3 MB gzipped, 162.6 MB uncompressed ] etc42 This distribution set contains the system configuration files that reside in /etc and in several other places. This set MUST be installed if you are installing the system from scratch, but should NOT be used if you are upgrading. (If you are upgrading, it's recommended that you get a copy of this set and CAREFULLY upgrade your configuration files by hand; see the section named Upgrading a previously-installed OpenBSD System" below.) [ 1.0 MB gzipped, 3.8 MB uncompressed ] game42 This set includes the games and their manual pages. [ 2.5 MB gzipped, 6.0 MB uncompressed ] man42 This set includes all of the manual pages for the binaries and other software contained in the base set. Note that it does not include any of the manual pages that are included in the other sets. [ 6.5 MB gzipped, 23.2 MB uncompressed ] misc42 This set includes the system dictionaries (which are rather large), and the typesettable document set. [ 2.1 MB gzipped, 7.1 MB uncompressed ] xbase42 This set includes the base X distribution. This includes programs, headers and libraries. [ 6.0 MB gzipped, 17.9 MB uncompressed ] xetc42 This set includes the X window system configuration files that reside in /etc. It's the equivalent of etc42 for X. [ 64.4 KB gzipped, 255.0 KB uncompressed ] xfont42 This set includes all of the X fonts. [ 31.6 MB gzipped, 35.8 MB uncompressed ] xserv42 This set includes all of the X servers. [ 482.1 KB gzipped, 1.0 MB uncompressed ] xshare42 This set includes all text files equivalent between all architectures. [ 1.9 MB gzipped, 10.5 MB uncompressed ] The directory '../4.2/mac68k/utils' contains the OpenBSD/mac68k boot program, used to load the OpenBSD kernel. This program is distributed as a self-extracting archive in Macintosh BinHex format. If there is no BSD/Mac68k booter already installed on your Mac OS system, you will need to download this file. OpenBSD System Requirements and Supported Devices: -------------------------------------------------- OpenBSD/mac68k 4.2 runs on several of the older Macintosh computers. 8MB of RAM should be sufficient to boot and a minimal system can probably be squeezed onto a 120MB partition by installing just the minimum sets. To actually do much compiling or anything more interesting than booting, more RAM and disk space is highly recommended. About 250MB will be necessary to install all of the OpenBSD 4.2 binary distribution (note that this does not count swap space!). A Mac OS partition is also required to install OpenBSD/mac68k 4.2 and boot it, see below. OpenBSD/mac68k 4.2 runs on most 680x0 Macintosh's. Specifically, it should work on: * 68020 with 68851 PMMU and 68881 FPU * 68030 with 68882 FPU (many Macs do not have this) * 68040 (not including the 68LC040) The following Macintosh models are supported and tested. This means that at least the SCSI controller, serial console and on-board ethernet will function on these models. On some of these machines, a full 68040 CPU is required to replace the default 68LC040 CPU. * LC family: LC 475, Performa 475, Performa 476 * Centris family: 610, 650 * Quadra family: 605, 610, 630, 650, 660AV, 700, 800, 840AV, 900, 950 Supported devices: * Internal SCSI controllers and peripherals: - Quadra/Centris series' onboard NCR 53c96 SCSI controller (esp). - Macintosh II-series', Performa, and LC-series' onboard NCR 5380 SCSI controller (ncrscsi, sbc). - SCSI disk drives (sd). - SCSI cdrom drives (cd). - Autochangers (ch). - Tape drives (st). * Internal sound (asc). * NuBus internal expansion bus (nubus). * Most NuBus video cards. * Both internal serial ports (zsc). * ADB keyboards and mice (adb) (except on the IIfx, Quadra 900 and 950). * Ethernet cards based on the Natl. Semiconductor 8390 (Asante, Apple, and a few others) (ae). * Quadra/Centris AV series' onboard MACE ethernet (mc). * Some ethernet cards based on the SONIC chip including internal Ethernet on many of Apple's non-AV Quadras/Centrises (sn). Untested systems: The following Macintosh models are untested and/or lack support for major subsystems. It is very likely that many of these system don't work at all. * Classic family: Color Classic, Classic II * Macintosh II family: Mac II, IIx, IIcx, IIci, IIsi, IIfx, IIvi, IIvx, Performa 600 * LC family: LC, LC II, LC III, LC III+, Performa 400-430, Performa 450, Performa 460 * 500 family: 520, 550, 575, 580, Mac TV OpenBSD/mac68k 4.2 does NOT run on these machines: * PowerPC-based Macs. Newer Mac PPC systems are supported by the OpenBSD/macppc port. * Powerbook family. Hardware capabilities limit the usability of these systems. * Machines based on the 68LC040 processor. Unfortunately, the chip itself contains a major bug for which there is no software workaround available in OpenBSD. Hardware that we do NOT currently support, but get many questions about: * Apple Communication Slot (CS) Ethernet cards. * Floppy drive. * IOP ADB subsystem on the IIfx, Quadra 900 and 950. * IDE drives. Getting the OpenBSD System onto Useful Media: --------------------------------------------- Installation is supported from several media types, including: CD-ROM FFS partitions (for upgrades only) Tape Remote NFS partition FTP HTTP The steps necessary to prepare the distribution sets for installation depend on which method of installation you choose. Some methods require a bit of setup first that is explained below. The installation allows installing OpenBSD directly from FTP mirror sites over the internet, however you must consider the speed and reliability of your internet connection for this option. It may save much time and frustration to use ftp get/reget to transfer the distribution sets to a local server or disk and perform the installation from there, rather than directly from the internet. Creating an installation tape: While you won't be able to boot OpenBSD from a tape, you can use one to provide the installation sets. To do so, you need to make a tape that contains the distribution set files, each in "tar" format or in "gzipped tar format". First you will need to transfer the distribution sets to your local system, using ftp or by mounting the CD-ROM containing the release. Then you need to make a tape containing the files. If you're making the tape on a UN*X-like system, the easiest way to do so is make a shell script along the following lines, call it "/tmp/maketape". #! /bin/sh TAPE=${TAPE:-/dev/nrst0} mt -f ${TAPE} rewind for file in base etc comp game man misc xbase xetc xfont xserv xshare do dd if=${file}42.tgz of=${TAPE} obs=8k conv=sync done tar cf ${TAPE} bsd mt -f ${TAPE} offline # end of script And then: cd .../4.2/mac68k sh -x /tmp/maketape If you're using a system other than OpenBSD or SunOS, the tape name and other requirements may change. You can override the default device name (/dev/nrst0) with the TAPE environment variable. For example, under Solaris, you would probably run: TAPE=/dev/rmt/0n sh -x /tmp/maketape Note that, when installing, the tape can be write-protected (i.e. read-only). To install OpenBSD using a remote partition, mounted via NFS, you must do the following: NOTE: This method of installation is recommended only for those already familiar with using BSD network configuration and management commands. If you aren't, this documentation should help, but is not intended to be all-encompassing. Place the OpenBSD distribution sets you wish to install into a directory on an NFS server, and make that directory mountable by the machine on which you are installing or upgrading OpenBSD. This will probably require modifying the /etc/exports file of the NFS server and resetting its mount daemon (mountd). (Both of these actions will probably require superuser privileges on the server.) You need to know the numeric IP address of the NFS server, and, if the server is not on a network directly connected to the machine on which you're installing or upgrading OpenBSD, you need to know the numeric IP address of the router closest to the OpenBSD machine. Finally, you need to know the numeric IP address of the OpenBSD machine itself. Once the NFS server is set up properly and you have the information mentioned above, you can proceed to the next step in the installation or upgrade process. If you are upgrading OpenBSD, you also have the option of installing OpenBSD by putting the new distribution sets somewhere in your existing file system, and using them from there. To do that, do the following: Place the distribution sets you wish to upgrade somewhere in your current file system tree. At a bare minimum, you must upgrade the "base" binary distribution, and so must put the "base42" set somewhere in your file system. It is recommended that you upgrade the other sets, as well. Preparing your System for OpenBSD Installation: ----------------------------------------------- If your machine only has one SCSI disk, you will need to share the disk with Mac OS. You might have to repartition and/or reinstall Mac OS in order to make room available for OpenBSD. Find your favorite disk partitioning utility. Some of the ones that have been tried and seem to work are: APS Powertools 2.7.3 SCSI Directory Lite Disk Manager Mac from OnTrack HD SC Setup from Apple I/O Formatter from Diversified (?) Silverlining from LaCie "HD SC Setup" is included with the supported versions of Mac OS. This utility ignores non-Apple hard disks unless you patch it with the application found at the following URL: http://www.euronet.nl/users/ernstoud/hdpatch.html Alternatively, one might prefer to use the A/UX version which does not have such a restriction, and can be found at the following URL: http://www.euronet.nl/users/ernstoud/hdsetup.html Prior to attempting to repartition your disk, everything of value on the drive should be backed up. All information on the drive you will be repartitioning will be lost. That done, use your favorite partitioning utility and make any necessary Mac OS partitions, then restore your data. You might want to create your OpenBSD partitions at this time, rather than with the "pdisk" utility during the installation itself. In this case, create one "A/UX Root" partition (for the / filesystem), one "Swap" partition (for swap, obviously), and as many "Usr file system" or "Unreserved" partitions as you want (for the other filesystems, such as /tmp, /usr, /var, etc). You will also need to install the BSD/Mac68k Booter on your Mac OS system. It is available in the utils/ subdirectory of the distribution, in self-extracting and binhex form as booter.sea.hqx. Extract it as you would for any other Macintosh application. Before moving on, you should make sure that your machine is running the correct software on the Mac OS side. In the Memory control panel, you should turn Virtual Memory off whenever you are planning to use the BSD/Mac68k Booter. You should also make sure that your machine is using 32-bit addressing. If there is no "Addressing:" option in your Memory control panel and your machine is supported, you will probably need Mode32. Mode32 is a control panel and extension combination which enables 32-bit addressing on older Macs which do not use it by default. This program is available from any Info-Mac mirror. All of that done and accounted for, you are now set to install OpenBSD on your hard drive. Installing the OpenBSD System: ------------------------------ Installing OpenBSD is a relatively complex process, but if you have this document in hand and are careful to read and remember the information which is presented to you by the install program, it shouldn't be too much trouble. You should now be ready to install OpenBSD. The following is a walk-through of the steps you will take while getting OpenBSD installed on your hard disk. If any question has a default answer, it will be displayed in brackets ("[]") after the question. If you wish to stop the installation, you may hit Control-C at any time, but if you do, you'll have to begin the installation process again from scratch. Using Control-Z to suspend the process may be a better option, or at any prompt enter '!' to get a shell, from which 'exit' will return you back to that prompt (no refresh of the prompt though). Double-click on the BSD/Mac68k Booter icon on the desktop to start the application. Go to the "Booting..." entry in the "Options" menu, and make it point to the bsd.rd kernel on your Mac OS filesystem. For the Quadra 605, LC 475, Performa 475 and Performa 476 models it is also necessary to activate the video address hack. Now boot the kernel. Once the kernel has loaded, you will be presented with the OpenBSD kernel boot messages. You will want to read them to determine your disks name and geometry. Its name will be something like "sd0". You will also need to know the device name to tell the install tools what disk to install on. If you cannot read the messages as they scroll by, do not worry -- you can get at this information later inside the install program. You will next be asked for your terminal type. You should choose the terminal type from amongst those listed. (If your terminal type is xterm, just use vt100). After entering the terminal type you will be asked whether you wish to do an "(I)nstall" or an "(U)pgrade". Enter 'I' for a fresh install or 'U' to upgrade an existing installation. You will be presented with a welcome message and asked if you really wish to install (or upgrade). Assuming you answered yes, the install program will then tell you which disks of that type it can install on, and ask you which it should use. Reply with the name of your disk. Next you will have to edit or create a disk label for the disk OpenBSD is being installed on. You will first be given an opportunity to run pdisk and create OpenBSD partitions. You will be issued a command prompt allowing you to modify the partition table. The most common operation, and the example presented here, deals with the creation of partitions for OpenBSD. Before editing, the partition table may look like the following: #: type name length base ( size ) 1: Apple_partition_map Apple 63 @ 1 2: Apple_Driver43*Macintosh 54 @ 64 3: Apple_Driver43*Macintosh 74 @ 118 4: Apple_Patches Patch Partition 512 @ 192 5: Apple_HFS untitled 61440 @ 704 ( 30.0M) 6: Apple_Free Extra 17711380 @ 62144 ( 8.4G) After editing the table, it should look like: #: type name length base ( size )^M 1: Apple_partition_map Apple 63 @ 1 2: Apple_Driver43*Macintosh 54 @ 64 3: Apple_Driver43*Macintosh 74 @ 118 4: Apple_Patches Patch Partition 512 @ 192 5: Apple_HFS untitled 61440 @ 704 ( 30.0M) 6: Apple_UNIX_SVR2 OpenBSD_Root 2097152 @ 62144 ( 1.0G) S0 RUFS k0 / 7: Apple_UNIX_SVR2 OpenBSD_Swap 262144 @ 2159296 (128.0M) S1 SFS k0 (swap) 8: Apple_UNIX_SVR2 OpenBSD_Usr 8388608 @ 2421440 ( 4.0G) S2 UFS k0 /usr 9: Apple_UNIX_SVR2 OpenBSD_Tmp 2097152 @ 10810048 ( 1.0G) S2 UFS k0 10: Apple_UNIX_SVR2 OpenBSD_Var 4866323 @ 12907200 ( 2.3G) S2 UFS k0 This will likely be different based on the number of partitions created on the disk by the Apple partition editor. It is _VERY_ important to not change the start, sizes, or types of partitions other than the ones that are to be used by OpenBSD, including the Apple_Driver.* and Apple_partition_map. The pdisk tool will automatically adjust the Apple_Free partition. --- Command (? for help): c First block: 62144 Length in blocks: 2097152 Name of partition: OpenBSD_Root Available partition slices for Apple_UNIX_SVR2: a root partition b swap partition c do not set any bzb bits g user partition Other lettered values will create user partitions Select a slice for default bzb values: a --- For the OpenBSD_Root slice, chose a bzb value of 'a', for OpenBSD_Swap 'b'. For any other slice do not set any bzb value ('c') except for OpenBSD_Usr, which can be set to 'g'. Next the disk label which defines the layout of the OpenBSD file systems must be set up. The installation script will invoke an interactive editor allowing you to do this. Note that partition 'c' inside this disk label should ALWAYS reflect the entire disk, including any non-OpenBSD portions. If you are labeling a new disk, you will probably start out with an 'a' partition that spans the disk. In this case you should delete 'a' before adding new partitions. The root file system should be in partition 'a', and swap is usually in partition 'b'. It is recommended that you create separate partitions for /usr, /tmp, and /var, and if you have room for it, one for /home. In doing this, remember to skip 'c', leaving it as type "unused". For help in the disk label editor, enter '?' or 'M' to view the manual page (see the info on the ``-E'' flag). OpenBSD/mac68k can share a disk with Mac OS by using an HFS partitioned disk. For proper layout, the disk should be partitioned with Mac OS first with unused space where OpenBSD can be installed. The swap partition (usually 'b') should have a type of "swap", all other native OpenBSD partitions should have a type of "4.2BSD". The install program will now label your disk and ask which file systems should be created on which partitions. It will auto- matically select the 'a' partition to be the root file system. Next it will ask for which disk and partition you want a file system created on. This will be the same as the disk name (e.g. "sd0") with the letter identifying the partition (e.g. "d") appended (e.g. "sd0d"). Then it will ask where this partition is to be mounted, e.g. /usr. This process will be repeated until you enter "done". At this point you will be asked to confirm that the file system information you have entered is correct, and given an opportunity to change the file system table. Next it will create the new file systems as specified, OVERWRITING ANY EXISTING DATA. This is the point of no return. After all your file systems have been created, the install program will give you an opportunity to configure the network. The network configuration you enter (if any) can then be used to do the install from another system using HTTP or FTP, and will also be the configuration used by the system after the installation is complete. If you select to configure the network, the install program will ask you for the name of your system and the DNS domain name to use. Note that the host name should be without the domain part, and that the domain name should NOT include the host name part. Next the system will give you a list of network interfaces you can configure. For each network interface you select to configure, it will ask for the IP address to use, the symbolic host name to use, the netmask to use, and any interface-specific flags to set. The interface-specific flags are usually used to determine which media the network card is to use. Typically no media flags are required as autodetection normally works, but you will be prompted with a list of the acceptable media flags, and asked if you want to provide any. In doubt, do not enter any media flags; or you can refer to the manual page for your interface for the appropriate flags. After all network interfaces have been configured, the install pro- gram will ask for a default route and IP address of the primary name server to use. You will also be presented with an opportunity to edit the host table. At this point you will be allowed to edit the file system table that will be used for the remainder of the installation and that will be used by the finished system, following which the new file systems will be mounted to complete the installation. After these preparatory steps have been completed, you will be able to extract the distribution sets onto your system. There are several install methods supported; FTP, HTTP, tape, {:­CD-ROMor a local disk partition. Note that installation from floppies is not currently supported. To install via FTP: To begin an FTP install you will need the following pieces of information. Don't be daunted by this list; the defaults are sufficient for most people. 1) Proxy server URL if you are using a URL-based FTP proxy (squid, CERN FTP, Apache 1.2 or higher). You need to define a proxy if you are behind a firewall that blocks outgoing FTP (assuming you have a proxy available to use). 2) Do you need to use active mode FTP? By default, ftp will attempt to use passive mode and fall back to an active connection if the server does not support passive mode. You only need to enable this option if you are connecting to a buggy FTP daemon that implements passive FTP incorrectly. Note that you will not be asked about active FTP if you are using a proxy. 3) The IP address (or hostname if you enabled DNS earlier in the install) of an FTP server carrying the OpenBSD 4.2 distribution. If you don't know, answer ``y'' when asked if you want to see a list of such hosts. 4) The FTP directory holding the distribution sets. The default value of pub/OpenBSD/4.2/mac68k is almost always correct. 5) The login and password for the FTP account. You will only be asked for a password for non-anonymous FTP. For instructions on how to complete the installation via FTP, see the section named "Common URL installations" below. To install via HTTP: To begin an HTTP install you will need the following pieces of information: 1) Proxy server URL if you are using a URL-based HTTP proxy (squid, CERN FTP, Apache 1.2 or higher). You need to define a proxy if you are behind a firewall that blocks outgoing HTTP connections (assuming you have a proxy available to use). 2) The IP address (or hostname if you enabled DNS earlier in the install) of an HTTP server carrying the OpenBSD 4.2 distribution. If you don't know, answer ``y'' when asked if you want to see a list of such hosts. 3) The directory holding the distribution sets. There is no standard location for this; You should use the directory specified along with the server in the list of official HTTP mirror sites that you received in step 3. For instructions on how to complete the installation via HTTP, see the section named "Common URL installations" below. To install from tape: In order to install from tape, the distribution sets to be installed must have been written to tape previously, either in tar format or gzip-compressed tar format. You will also have to identify the tape device where the distribution sets are to be extracted from. This will typically be "nrst0" (no-rewind, raw interface). Next you will have to specify how many files have to be skipped on the tape. This number is usually zero. The install program will not automatically detect whether an image has been compressed, so it will ask for that information before starting the extraction. To install from CD-ROM: When installing from a CD-ROM, you will be asked which device holds the distribution sets. This will typically be "cd0". Next you will be asked which partition on the CD-ROM the distribution is to be loaded from. This is normally partition "a". Next you will have to identify the file system type that has been used to create the distribution on the CD-ROM, this can be either FFS or ISO CD9660. The OpenBSD CD-ROM distribution uses the CD9660 format. You will also have to provide the relative path to the directory on the CD-ROM which holds the distribution, for the mac68k this is "4.2/mac68k". For instructions on how to complete the installation from the CD-ROM distribution, see the section named "Common file system installations" below. To install from an NFS mounted directory: When installing from an NFS-mounted directory, you must have completed network configuration above, and also set up the exported file system on the NFS server in advance. First you must identify the IP address of the NFS server to load the distribution from, and the file system the server expects you to mount. The install program will also ask whether or not TCP should be used for transport (the default is UDP). Note that TCP only works with newer NFS servers. You will also have to provide the relative path to the directory on the file system where the distribution sets are located. Note that this path should not be prefixed with a '/'. For instructions on how to complete the installation from the CD-ROM distribution, see the section named "Common file system installations" below. Common file system installations: The following instructions are common to installations from mounted disk partitions, NFS mounted directories and CD-ROMs. A list of available distribution sets will be listed. You may individually select distribution sets to install or enter `all' to install all of the sets (which is what most users will want to do). You may also enter `list' to get a file list or `done' when you are done selecting distribution sets. You may also use wildcards in place of a file name, e.g. `*.tgz' or even `base*|comp*'. It is also possible to enter an arbitrary filename and have it treated as a file set. Once you have selected the file sets you want to install and entered `done' you will be prompted to verify that you really do want to extract file sets. Assuming you acquiesce, the files will begin to extract. If not, you will be given the option of installing sets via one of the other install methods. Common URL installations: Once you have entered the required information, the install program will fetch a file list and present a list of all the distribution sets that were found in the specified directory. (If no valid sets were found, you will be notified and given the option of unpacking any gzipped tar files found or getting a file list if none were found.) At this point you may individually select distribution sets to install or enter `all' to install all of the sets (which is what most users will want to do). You may also enter `list' to get a file list or `done' when you are done selecting distribution sets. You may also use wildcards in place of a file name, e.g. `*.tgz' or even `base*|comp*'. It is also possible to enter an arbitrary filename and have it treated as a file set. Once you have selected the file sets you want to install and entered `done' you will be prompted to verify that you really do want to download and install the files. Assuming you acquiesce, the files will begin to download and unpack. If not, you will be given the option of installing sets via one of the other install methods. When all the selected distribution sets has been extracted, you will be allowed to select which time zone your system will be using, all the device nodes needed by the installed system will be created for you, and the file systems will be unmounted. For this to work properly, it is expected that you have installed at least the "base42", "etc42", and "bsd" distribution sets. Once the installation is complete, reboot into Mac OS, and start the BSD/Mac68k Booter again. This time, point to the OpenBSD kernel location on its own partition. You will have to change the kernel name to "bsd" or "bsdsbc", depending which one you have installed. Be sure to check that the SCSI ID is correct as well. Note that by setting the BSD/Mac68k Booter to boot automatically after starting, and by placing an alias to the booter in the "Startup Items" folder, one can make the Mac68k autoload OpenBSD upon startup. Congratulations, you have successfully installed OpenBSD 4.2. When you reboot into OpenBSD, you should log in as "root" at the login prompt. You should create yourself an account and protect it and the "root" account with good passwords. The install program leaves root an initial mail message. We recommend you read it, as it contains answers to basic questions you might have about OpenBSD, such as configuring your system, installing packages, getting more information about OpenBSD, sending in your dmesg output and more. To do this, run mail and then just enter "more 1" to get the first message. You quit mail by entering "q". Some of the files in the OpenBSD 4.2 distribution might need to be tailored for your site. We recommend you run: man afterboot which will tell you about a bunch of the files needing to be reviewed. If you are unfamiliar with UN*X-like system administration, it's recommended that you buy a book that discusses it. Upgrading a previously-installed OpenBSD System: ------------------------------------------------ Warning! Upgrades to OpenBSD 4.2 are currently only supported from the immediately previous release. The upgrade process will also work with older releases, but might not execute some migration tasks that would be necessary for a proper upgrade. The best solution, whenever possible, is to backup your data and reinstall from scratch. To upgrade OpenBSD 4.2 from a previous version, start with the general instructions in the section "Installing OpenBSD". Boot from the bsd.rd kernel. When prompted, select the (U)pgrade option rather than the (I)nstall option at the prompt in the install process. The upgrade script will ask you for the existing root partition, and will use the existing filesystems defined in /etc/fstab to install the new system in. It will also use your existing network parameters. From then, the upgrade procedure is very close to the installation procedure described earlier in this document. Note that the upgrade procedure will not let you pick the ``etc42.tgz'' set, so as to preserve your files in `/etc' which you are likely to have customized since a previous installation. However, it is strongly advised that you unpack the etc42.tgz set in a temporary directory and merge changes by hand, since all components of your system may not function correctly until your files in `/etc' are updated. Getting source code for your OpenBSD System: -------------------------------------------- Now that your OpenBSD system is up and running, you probably want to get access to source code so that you can recompile pieces of the system. A few methods are provided. If you have an OpenBSD CD-ROM, the source code is provided. Otherwise, you can get the pieces over the Internet using anonymous CVS, CTM, CVSync or FTP. For more information, see http://www.OpenBSD.org/anoncvs.html http://www.OpenBSD.org/ctm.html http://www.OpenBSD.org/cvsync.html http://www.OpenBSD.org/ftp.html Using online OpenBSD documentation: ----------------------------------- Documentation is available if you first install the manual pages distribution set. Traditionally, the UN*X "man pages" (documentation) are denoted by 'name(section)'. Some examples of this are intro(1), man(1), apropos(1), passwd(1), passwd(5) and afterboot(8). 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 least-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. Adding third party software; ``packages'' and ``ports'': -------------------------------------------------------- As complete as your OpenBSD system is, you may want to add any of several excellent third party software applications. There are several ways to do this. You can: 1) Obtain the source code and build the application based upon whatever installation procedures are provided with the application. 2) Use the OpenBSD ``ports'' collection to automatically get any needed source file, apply any required patches, create the application, and install it for you. 3) Use the OpenBSD ``package'' collection to grab a pre-compiled and tested version of the application for your hardware. If you purchased the OpenBSD CD-ROM set you already have several popular ``packages'', and the ``ports'' collection. Instructions for installing applications from the various sources using the different installation methods follow. You should also refer to the packages(7) manual page. Installing applications from the CD-ROM package collection: The OpenBSD CD-ROM ships with several applications pre-built for various hardware architectures. The number of applications vary according to available disk space. Check the directory 4.2/packages/m68k to see which packages are available for your hardware architecture. That directory will be on the same CD-ROM containing the OS installation files for your architecture. To install one or more of these packages you must: 1) become the superuser (root). 2) mount the appropriate CD-ROM. 3) use the ``pkg_add'' command to install the software. Example (in which we use su(1) to get superuser privileges, thus you have to be in group "wheel", see the manual page for su(1)). $ su Password: # mkdir -p /cdrom # mount /dev/cd0a /cdrom # pkg_add /cdrom/4.2/packages/m68k/ # # umount /cdrom Package names are usually the application name and version with .tgz appended, e.g. emacs-21.3.tgz Installing applications from the ftp.OpenBSD.org package collection: All available packages for your architecture have been placed on ftp.OpenBSD.org in the directory pub/OpenBSD/4.2/packages/m68k/ You may want to peruse this to see what packages are available. The packages are also on the OpenBSD FTP mirror sites. See http://www.OpenBSD.org/ftp.html for a list of current FTP mirror sites. Installation of a package is very easy. 1) become the superuser (root) 2) use the ``pkg_add'' command to install the software ``pkg_add'' is smart enough to know how to download the software from the OpenBSD FTP server. Example: $ su Password: # pkg_add \ ftp://ftp.OpenBSD.org/pub/OpenBSD/4.2/packages/m68k/emacs-21.3.tgz Installing applications from the CD-ROM ports collection: The CD-ROM ``ports'' collection is a set of Makefiles, patches, and other files used to control the building and installation of an application from source files. Creating an application from sources can require a lot of disk space, sometimes 50 megabytes or more. The first step is to determine which of your disks has enough room. Once you've made this determination, read the file PORTS located on the CD-ROM which contains the ports tree. To build an application you must: 1) become the superuser (root) 2) have network access, or obtain the actual source files by some other means. 3) cd to the ports directory containing the port you wish to build. To build samba, for example, where you'd previously copied the ports files into the /usr/ports directory: cd /usr/ports/net/samba 4) make 5) make install 6) make clean Installing applications from the OpenBSD ports collection: See http://www.OpenBSD.org/ports.html for current instructions on obtaining and installing OpenBSD ports. You should also refer to the ports(7) manual page. Installing other applications: If an OpenBSD package or port does not exist for an application you're pretty much on your own. The first thing to do is ask if anyone is working on a port -- there may be one in progress. If no such port exists, you might want to tinker with the NetBSD pkgsrc. If you can't find an existing port, try to make your own and feed it back to OpenBSD. That's how our ports collection grows. Some details can be found at http://www.OpenBSD.org/porting.html with more help coming from the mailing list, . Administrivia: -------------- There are various mailing lists available via the mailing list server at . To get help on using the mailing list server, send mail to that address with an empty body, and it will reply with instructions. There are also two OpenBSD Usenet newsgroups, comp.unix.bsd.openbsd.announce for important announcements and comp.unix.bsd.openbsd.misc for general OpenBSD discussion. To report bugs, use the 'sendbug' command shipped with OpenBSD, and fill in as much information about the problem as you can. Good bug reports include lots of details. Additionally, bug reports can be sent by mail to: bugs@OpenBSD.org Use of 'sendbug' is encouraged, however, because bugs reported with it are entered into the OpenBSD bugs database, and thus can't slip through the cracks. As a favor, please avoid mailing huge documents or files to the mailing lists. Instead, put the material you would have sent up for FTP somewhere, then mail the appropriate list about it, or, if you'd rather not do that, mail the list saying you'll send the data to those who want it. For more information about reporting bugs, see http://www.OpenBSD.org/report.html
