INSTALLATION NOTES for OpenBSD/alpha 5.6 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. Because OpenBSD is from Canada, the export of Cryptography pieces (such as OpenSSH and IPsec) 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 5.6 release is available on the web at http://www.OpenBSD.org/56.html. OpenBSD/alpha runs on a broad range of Alpha processor-based machines, including workstations manufactured by Digital (then Compaq, now HP), as well as OEM motherboards designed by Samsung and Alpha Processor, Inc. Sources of OpenBSD: ------------------- Please refer to http://www.openbsd.org/ftp.html for all the ways you may acquire OpenBSD. OpenBSD 5.6 Release Contents: ----------------------------- The OpenBSD 5.6 release is organized in the following way. In the .../5.6 directory, for each of the architectures having an OpenBSD 5.6 binary distribution, there is a sub-directory. The alpha-specific portion of the OpenBSD 5.6 release is found in the "alpha" subdirectory of the distribution. That subdirectory is laid out as follows: .../5.6/alpha/ INSTALL.alpha Installation notes; this file. SHA256 Output of the sum(1) program using the option -a sha256, usable for verification of the correctness of downloaded files. SHA256.sig The above file, signed with the OpenBSD signing key for the 5.6 release, usable for verification of the integrity of the above file, and thus of the downloaded files. floppy56.fs The standard alpha boot and installation floppy; see below. This floppy image will boot on the following alpha models: - AlphaStation 200, 250, 255, 400 - AlphaServer 300 and 400 - AlphaStation 500, 600 - AlphaStation 600A, 1200 - AlphaServer 800, 1000, 1000A, 1200, 4000 and 4100 - AXPpci33 based machines, including ``Noname'', UDB, Multia - EB164 based machines, including PC164, 164SX, and 164LX - Personal Workstation (Miata) floppyB56.fs Another alpha boot and installation floppy; see below. This floppy image will boot on the following alpha models: - Alpha Processor, Inc. UP1000, UP1100, UP2000 and UP2000+ - XP900, XP1000, CS20, DS10, DS20, DS20L, ES40 and 264DP floppyC56.fs Another alpha boot and installation floppy; see below. This floppy image will boot on the following alpha models: - Tadpole AlphaBook *.tgz alpha binary distribution sets; see below. bsd A stock GENERIC alpha kernel which will be installed on your system during the install. bsd.mp A stock GENERIC.MP alpha kernel, with support for multiprocessor machines, which can be used instead of the GENERIC kernel after the install. bsd.rd A compressed RAMDISK kernel; the embedded filesystem contains the installation tools. Used for simple installation from a pre-existing system. install56.iso The alpha boot and installation CD-ROM image, which contains the base and X sets, so that install or upgrade can be done without network connectivity. cd56.iso A simple bootable filesystem image consisting of the bsd.rd installation kernel, suitable to be used as a bootable CD-ROM image, but will require the base and X sets be found via another media or network. Bootable installation/upgrade floppy images: The three floppy images can be copied to a floppy using rawrite.exe, ntrw.exe, or `dd', as described later in this document. Each floppy image is a bootable install floppy which can be used both to install and to upgrade OpenBSD to the current version. It is also useful for maintenance and disaster recovery. The OpenBSD/alpha binary distribution sets contain the binaries which comprise the OpenBSD 5.6 release for alpha systems. There are ten binary distribution sets. The binary distribution sets can be found in the "alpha" subdirectory of the OpenBSD 5.6 distribution tree, and are as follows: base56 The OpenBSD/alpha 5.6 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. [ 64.2 MB gzipped, 196.9 MB uncompressed ] comp56 The OpenBSD/alpha Compiler tools. All of the tools relating to C, C++ and Objective-C 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. [ 48.0 MB gzipped, 182.5 MB uncompressed ] etc56 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.) [ 176.5 KB gzipped, 611.3 KB uncompressed ] game56 This set includes the games and their manual pages. [ 2.7 MB gzipped, 6.6 MB uncompressed ] man56 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. [ 8.7 MB gzipped, 34.2 MB uncompressed ] xbase56 This set includes the base X distribution. This includes programs, headers and libraries. [ 17.1 MB gzipped, 59.0 MB uncompressed ] xetc56 This set includes the X window system configuration files that reside in /etc. It's the equivalent of etc56 for X. [ 67.4 KB gzipped, 279.3 KB uncompressed ] xfont56 This set includes all of the X fonts. [ 38.0 MB gzipped, 49.7 MB uncompressed ] xserv56 This set includes all of the X servers.

On other systems, including all TURBOchannel-based machines, OpenBSD/alpha *must* be used with a serial console. Verifying the OpenBSD Installation Media: ----------------------------------------- As of OpenBSD 5.5, installations are able to verify files for the next release. The OpenBSD 5.6 release was signed with the /etc/signify/openbsd-56-base.pub release key. If you have an existing OpenBSD 5.5 or higher installation, you can run signify(1) to verify the signature and checksum. For example, run the following to verify that the cd56.iso file was distributed by the OpenBSD team: signify -C -p /etc/signify/openbsd-56-base.pub -x SHA256.sig cd56.iso If you are unable to run or compile signify(1), use sha256(1) with the SHA256 file to see if a file was corrupt during the transfer. Getting the OpenBSD System onto Useful Media: --------------------------------------------- Installation is supported from several media types, including: CD-ROM (NOT supported if booting from floppy) FFS partitions FTP HTTP If you can burn the bootable CD-ROM mini image, you can boot from it. Otherwise, you will need to create a bootable floppy disk. Creating a bootable CD-ROM: First you need to get access to the OpenBSD bootable CD-ROM (ISO) images. They can be found on one of the FTP or HTTP mirrors. Two files are available, install56.iso which contains all of the sets needed for installation, and a smaller cd56.iso which contains just the installer, for a network install. Windows 7 users should be able to do this by right clicking on the install56.iso file and clicking burn to CD. OpenBSD users should be able to do this with the cdio command. "cdio tao install56.iso" Users of other operating systems should consult the appropriate documentation. Creating a bootable floppy disk using Windows: First you need to get access to the OpenBSD bootable floppy images. If you can access the distribution from the CD-ROM under DOS, you will find the bootable disks in the 5.6/alpha directory. Otherwise, you will have to download them from one of the OpenBSD FTP or HTTP mirror sites, using an FTP client or a web browser. In either case, take care to do "binary" transfers, since these are images files and any DOS cr/lf translations or Control-z EOF interpretations will result in corrupted transfers. You will also need to go to the "tools" directory and grab a copy of the ntrw.exe utility. Run it with the correct arguments like this "ntrw :" Note that, when installing, the boot floppy can be write-protected (i.e. read-only). Creating a bootable floppy disk using a Un*x-like system: First, you will need to obtain a local copy of the bootable filesystem image as described above. You should use the signify(1) and sha256(1) commands to verify the integrity of the images with the SHA256.sig file on the mirror site. Next, use the dd(1) utility to copy the file to the floppy drive. The command would likely be, under OpenBSD: dd if=floppy56.fs of=/dev/rfd0c bs=36b If you are using another operating system, you may have to adapt this to conform to local naming conventions for the floppy and options suitable for copying to a "raw" floppy image. The key issue is that the device name used for the floppy *must* be one that refers to the correct block device, not a partition or compatibility mode, and the copy command needs to be compatible with the requirement that writes to a raw device must be in multiples of 512-byte blocks. The variations are endless and beyond the scope of this document. If you're doing this on the system you intend to boot the floppy on, copying the floppy back to a file and doing a compare or checksum is a good way to verify that the floppy is readable and free of read/write errors. Note that, when installing, the boot floppy can be write-protected (i.e. read-only). If you neither have a floppy drive nor a CD-ROM drive on your alpha: If you don't have a floppy drive you can copy the floppy image onto the hard disk you intend to install OpenBSD on. Doing so will overwrite the disk's old contents, however. You must use a UN*X-like system to write the floppy image to the hard disk you will be using for OpenBSD/alpha. You should use the "dd" command to copy the file system image (floppy56.fs or floppyB56.fs) directly to the raw 'c' device (whole disk) of the target hard disk. It is suggested that you read the dd(1) manual page or ask your system administrator to determine the correct set of arguments to use; it will be slightly different from system to system, and a comprehensive list of the possibilities is beyond the scope of this document. Please note that this will put a floppy disklabel on your disk which will confuse the install script. To fix this you need to ask for a shell (answer "s" to the first question) when booting your disk and do "dd if=/dev/zero of=/dev/rsd0c count=20", assuming you booted from sd0. After doing this you will not be able to boot that disk again unless you complete the install. You can now enter "install" and start the actual install process. 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. 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 "base56" set somewhere in your file system. It is recommended that you upgrade the other sets, as well. Preparing your System for OpenBSD Installation: ----------------------------------------------- OpenBSD/alpha requires the SRM console. Some alphas come with the AlphaBIOS (also known as the ARC firmware on older machines) instead; this is what Windows NT uses. It is fairly simple to replace the AlphaBIOS with the SRM firmware. Switching your alpha to SRM console: AlphaServer class machines (except for models 300 and 400) and recent enough machines (such as the Miata and later models) have enough flash ROM space to carry both the AlphaBIOS and the SRM console. To switch to SRM from AlphaBIOS, do the following: - enter the AlphaBIOS setup upon startup (F2 key, or Ctrl-B from serial console) - choose "CMOS Setup" from the menu - select "Advanced CMOS Setup" (F6 key, or Ctrl-F from serial console) - change the "Console Selection" setting to "OpenVMS console (SRM)" - confirm your changes with F10 (or Ctrl-U) twice, then enter. - power-cycle your system for the changes to take effect. If you didn't find a "Console Selection" entry (for example on 164SX or 164LX), your system can not hold both the AlphaBIOS and SRM console in flash, and you will have to upgrade your firmware. You can get replacement firmware either from a firmware update CD-ROM, which can be downloaded from ftp://ftp.hp.com/pub/alphaserver/firmware/v73.zip However, this CD-ROM image only supports AlphaServer DS10, DS20, DS20L, and ES40. Firmware update for other models can be picked individually via FTP from ftp://ftp.hp.com/pub/alphaserver/firmware/retired_platforms/ Please refer to http://h18002.www1.hp.com/alphaserver/firmware/index.html for more information. Note that, on most models, upgrading the firmware requires a jumper to be moved on the motherboards; refer to the firmware update instructions for details. AXPpci33 Motherboard specific notes: The 1994 version of the OEM guide has an incorrect pinout for the serial ports. The newer version used to be available at ftp://ftp.digital.com/pub/Digital/axppci/design_guide.ps.Z with a corrected pinout (as well as more information than the 1994 edition). Although ftp.digital.com does not exist anymore, a few copies of this document are scattered accross various ftp servers on the globe, such as ftp://ftp.uniroma2.it/Digital/support/axppci/design_guide.ps.Z or http://vt100.net/mirror/mds-199909/cd1/alpha/axpcidgc.pdf Note that there are two flavors of PC serial connectors. If you have the wrong kind, you won't get any output from the serial console. Using the SRM console: This is not intended to be an exhaustive guide on using the SRM firmware console. It should, however, give you enough information to boot OpenBSD/alpha. To see a list of devices connected to your alpha, you can use the "show device" command. For booting, the devices you are interested in are "dva0" (the floppy drive) and "dka*" (the disk drives). You can set ROM variables by saying "set VARIABLE VALUE". Some variables you will want to set: auto_action Determines what happens when you turn the power on, halt, or restart your machine. Valid values are: "halt" the system will not autoboot, will restart when rebooted (shutdown -r), and will not restart when halted (shutdown -h). "boot" the system will autoboot on powerup, and when the system is halted (shutdown -h) or rebooted (shutdown -r). "restart" the system will autoboot on powerup, will restart when rebooted (shutdown -r), and will not restart when halted (shutdown -h). Most users will want to set this to "restart". bootdef_dev Default boot device (or list of devices). boot_file Name of the kernel to boot. If this variable is empty, "bsd" will be loaded. Note that this variable does not exist in all versions of the SRM console, in which case you need to always boot manually and specify a kernel filename if it differs from "bsd". boot_osflags Flags to pass to the kernel (there is no need to prefix them with a `-' dash sign). To see a list of all variables on your machine, use the "show" command with no arguments. If there are too many of them, you might want to page with "show | more". You can bypass the boot_file and boot_osflags values from the command prompt, with the -fi (to override boot_file) and -fl (to override boot_osflags) options. For example, boot -fi bsd -fl c dka0 will boot the "bsd" kernel with the "c" flag on dka0. However, some versions of the SRM console (mainly on DEC 3000 series) will only let you specify uppercase filenames. USB support on the XP1000: For some unknown reason, the USB interface found on the XP1000 (and possibly the XP900 and the XP1100) is not enabled unless a specific SRM environment variable is set. If you plan to use USB devices on these machines, enter set usb_enable on at the SRM prompt, followed by init before attempting to install OpenBSD. EISA configuration: A few alpha systems support EISA devices. However, the SRM firmware has only a very limited knowledge of EISA devices and is not able to configure them. Every time an EISA board is added to or removed from the system, the EISA Configuration Utility needs to be run from a floppy disk using the ``runecu'' command at the SRM prompt. An ECU floppy disk is supposed to be provided with EISA-capable systems; this disk will be updated with the current configuration every time it is run, and needs to be writeable. ECU disks should not be shared between systems. Redistributing ECU is not allowed, however a copy of it can be downloaded from: ftp://ftp.hp.com/pub/alphaserver/firmware/other/utility/ecu/ntecuv111a.zip Extract this archive to a newly FAT-formated 3"1/2 floppy disk to get a pristine ECU disk. SRM console boot device restrictions: The SRM firmware on your system may or may not be able to boot from any disk controller you may install in your alpha. The built-in disk controllers on your alpha will always be supported, however on IDE-based machines, such as the EB164, 164SX and 164LX, as well as the low-end Personal Workstation (non-u models), you can plug in a SCSI controller, and boot from it if it is recognized. Recent SRM releases for these machines will be able to boot (or netboot) from the following controllers: QLogic PCI SCSI controllers Symbios Logic (NCR) 53C8xx (but not on PC164) Adaptec AHA-[23]9[34]x[U][W] cards Intel i8255x-based cards (EtherExpress PRO) The following controllers are known not to be supported as boot devices by the SRM: Adaptec AHA-[23]9[34]xU2 cards Depending on your specific model, your mileage may vary, though. OpenBSD/alpha console device restrictions: On systems with no framebuffer supported (currently all TURBOchannel-based machines), OpenBSD/alpha must be used with a serial console. Setting an Alpha system to use a serial console is system-specific. Although most models will default to serial console if no keyboard is connected on powerup, this behaviour can't be relied upon. The recommended procedure is: DEC 3000/[4-9]00 Flip the `S3' switch on the back of the machine (up for glass console, down for serial console). When configured to use a serial console, it is also necessary to set the ``server'' SRM environment variable to ``on'' for the system to autoboot on powerup despite the lack of a keyboard and mouse plugged in. DEC 3000/300 family machines Console is selected by the `W2' jumper block, to the edge of the logic board, near the memory banks. Setting the jumper cap on pins 1-2 selects glass console, and on pins 2-3 selects serial console. All other machines From the SRM console, enter either set console serial or set console graphics at the SRM prompt, then enter init or cycle power. Installing the OpenBSD System: ------------------------------ Installing OpenBSD is a relatively simple process. If you take your time and are careful to read the information presented by the installer, you shouldn't have any trouble. There are several ways to install OpenBSD onto a disk. The easiest way is to boot from the bootable CD-ROM mini image, then install from your favorite source. You can also use one of the OpenBSD installation floppies, if your machine has a floppy drive. Network booting is supported through means of dhcpd(8) and tftpd(8). Booting from Floppy Disk installation media: At the SRM console prompt, enter boot dva0 You should see info about the primary and secondary boot and then the kernel should start to load. It will take a while to load the kernel from the floppy, most likely more than a minute. If some action doesn't eventually happen, or the spinning cursor has stopped and nothing further has happened, or the machine spontaneously reboots, then either you have a bad boot floppy (in which case you should try another) or your alpha is not currently supported by OpenBSD. Booting from CD-ROM installation media: At the SRM console prompt, enter show device to find the device ID of your CD-ROM drive (the device ID is usually in the second column (``bootdev'') and should start with DKA for a SCSI CD-ROM drive). If your drive shows up with a drive number with trailing zeros, you will want to ignore them (unless it is DKA0). For example, if your CD-ROM drive is listed as DKA600, you want to use dka6 (device IDs are case insensitive). Insert the OpenBSD/alpha CD-ROM and enter boot DEVICE where DEVICE is the dka device name. You should see info about the primary and secondary boot and then the kernel should start to load. If the kernel fails to load or the spinning cursor has stopped and nothing further has happened, you either have a hardware problem or your alpha is not currently supported by OpenBSD; try booting from a floppy instead if possible. Booting from Network: In order to bootstrap via the network, you must provide a second system to act as a boot server. It is convenient if this is a second OpenBSD machine as the necessary services are already installed, although source code for such programs as dhcpd can be found in OpenBSD's source tree, and should be reasonably portable to other UN*X-like operating systems. More information on diskless booting can be found in the OpenBSD diskless(8) manual page. In this case, you will need to set up dhcpd on the server, which can serve bootp protocol requests. Start by editing the /etc/dhcpd.conf on the bootserver, and declare an information block. Here is an example: subnet 10.0.0.0 netmask 255.0.0.0 { host piper { always-reply-rfc1048 "true"; filename "netboot"; option root-path "/alpha"; hardware ethernet 00:02:56:00:73:31; fixed-address 10.42.42.42; } } Do not forget to enable dhcpd. You will also need to enable tftpd, for the alpha to download the "netboot" from the server in the /tftpboot directory. Next, you need to add an entry for your alpha in /etc/bootparams. For example: piper root=myserver:/alpha Enable rpc.bootparamd either by turning it on in /etc/rc.conf and rebooting, or by running it manually. Only uncompressed kernels are supported for booting in this release. This means you have to execute the following command on your boot server before installing a new kernel for your alpha to boot: # gzip -dc bsd.rd > /alpha/bsd This assumes you have path /alpha exported via NFS. Once loaded, netboot will mount /alpha over NFS and load the kernel from there. Installing using the Floppy, CD-ROM or Network procedure: 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. The installation procedure is designed to gather as much information about your system setup as possible at the beginning, so that no human interaction is required as soon as the questions are over. The order of these questions might be quite disconcerting if you are used to other installation procedures, including older OpenBSD versions. 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 will occur, though). Boot your machine from the installation media as described above. It will take a while to load the installation kernel, especially from a slow network connection or a CD-ROM, most likely more than a minute. If some action doesn't eventually happen, or the spinning cursor has stopped and nothing further has happened, either your boot media is bad, your diskless setup is incorrect, or you may have a hardware or configuration problem. Once the kernel has loaded, you will be presented with the OpenBSD kernel boot messages which contain information about the hardware that was detected and supported by OpenBSD. After the kernel is done initialising, you will be asked whether you wish to do an "(A)utoinstall", "(I)nstall" or an "(U)pgrade". Enter 'I' for a fresh install or 'U' to upgrade an existing installation. Enter 'A' to start an unattended installation where all of your answers are supplied in a response file (more on that in "Preparing an unattended installation of OpenBSD"). If you are connected with a serial console, 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 vt220). The first question you will be asked is the system hostname. Reply with the name of the system, without any domain part. You will now be given 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. The install program will give you a list of network interfaces you can configure. For each network interface you select to configure, you will be asked for: - the symbolic host name to use (except for the first interface setup, which will reuse the host name entered at the beginning of the installation). - the IPv4 settings: address and netmask. If the IP address should be obtained from a DHCP server, simply enter ``dhcp'' when asked for the address. - the IPv6 settings (address, prefix length, and default router). You may enter ``rtsol'' when asked for the address for the interface to configure automatically via router solicitation messages. After all interfaces have been configured, if there have been any IPv4 interfaces setup, you will be asked for the IPv4 default route. This step is skipped if you only have one IPv4 interface setup, and it is configured with DHCP. The install program will also ask you for your DNS domain name, and the domain name servers, unless this information has already been obtained from a DHCP server during interface setup. You will also be presented with an opportunity to do more manual configuration. If you accept, you will be dropped to a shell; when you are done, enter `exit' to return to the installation program. You will then be asked to enter the initial root password of the system, twice. Although the install program will only check that the two passwords match, you should make sure to use a strong password. As a minimum, the password should be at least eight characters long and a mixture of both lower and uppercase letters, numbers and punctuation characters. You will then be asked whether you want to start sshd(8) by default, as well as ntpd(8). If you choose to start ntpd(8), you will be asked for your ntp server; if you don't have any preferred ntp server, press enter to confirm the default setting of using the pool.ntp.org servers. You will next be asked whether you intend to run the X Window System on your machine. The install program needs to know this, to change a configuration setting controlling whether the X server will be able to access the xf86(4) driver; it is not necessary to answer `y' to this question if you only intend to run X client programs on a remote display. If you are installing using a serial console, and since by default, the OpenBSD/alpha installation will only start terminals on the primary display device, the installation program will ask you whether you want to also enable an additional terminal on that line, and will allow you to select the line speed. You will now be given the possibility to setup a user account on the forthcoming system. This user will be added to the `wheel' group. Enter the desired login name, or `n' if you do not want to add a user account at this point. Valid login names are sequences of digits and lowercase letters, and must start with a lowercase letter. If the login name matches this criteria, and doesn't conflict with any of the administrative user accounts (such as `root', `daemon' or `ftp'), you will be prompted with the users descriptive name, as well as its password, twice. As for the root password earlier, the install program will only check that the two passwords match, but you should make sure to use a strong password here as well. If you have chosen to setup a user account, and you had chosen to start sshd(8) on boot, you will be given the possibility to disable sshd(8) logins as root. You may now be given the opportunity to configure the time zone your system will be using (this depends on the installation media you are using). If the installation program skips this question, do not be alarmed, the time zone will be configured at the end of the installation. The installation program will now tell you which disks it can install on, and ask you which it should use. Reply with the name of your root disk. You will the be asked if you want to use DUID notation in /etc/fstab, instead of traditional device names. You are strongly advised to use DUIDs, as they allow you to move your disks to different controllers, or change their bus identifiers, without having to modify /etc/fstab every time your configuration changes. Next the disk label which defines the layout of the OpenBSD partitions must be set up. Each file system you want will require a separate partition. You will be proposed a default partition layout, trying to set up separate partitions, disk size permitting. You will be given the possibility to either accept the proposed layout, or edit it, or create your own custom layout. These last two choices will invoke the disklabel(8) interactive editor, allowing you to create your desired layout. Within the editor, you will probably start out with only the 'c' partition of fstype 'unused' that represents the whole disk. This partition can not be modified. You must create partition 'a' as a native OpenBSD partition, i.e. one with "4.2BSD" as the fstype, to hold the root file system. In addition to partition 'a' you should create partition 'b' with fstype "swap", and native OpenBSD partitions to hold separate file systems such as /usr, /tmp, /var, and /home. You will need to provide a mount point for all partitions you define. Partitions without mount points, or not of 4.2BSD fstype, will neither be formatted nor mounted during the installation. For quick help while in the interactive editor, enter '?'. The `z' command (which deletes all partitions and starts with a clean label), the `A' command (which performs the automatic partition layout) and the `n' command (to change mount points) are of particular interest. Although the partitions position and size are written in exact sector values, you do not need a calculator to create your partitions! Human-friendly units can be specified by adding `k', `m' or `g' after any numbers to have them converted to kilobytes, megabytes or gigabytes. Or you may specify a percentage of the disk size using `%' as the suffix. Enter 'M' to view the entire manual page (see the info on the ``-E'' flag). To exit the editor enter 'q'. After the layout has been saved, new filesystems will be created on all partitions with mount points. This will DESTROY ALL EXISTING DATA on those partitions. After configuring your root disk, the installer will return to the list of available disks to configure. You can choose the other disks to use with OpenBSD in any order, and will get to setup their layout similarly to the root disk above. However, for non-root disks, you will not be proposed a default partition layout. When all your disks are configured, simply hit return at the disk prompt. 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, CD-ROM, or a local disk partition. To install via FTP or HTTP: To begin an FTP or HTTP install you will need the following pieces of information: 1) Proxy server URL if you are using a URL-based FTP or 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 FTP or HTTP connections (assuming you have a proxy available to use). 2) The IP address (or hostname if you configured DNS servers earlier in the install) of an FTP or HTTP server carrying the OpenBSD 5.6 distribution. The installation program will try to fetch a list of such servers; depending on your network settings, this might fail. If the list could be fetched, it will be displayed, and you can choose an entry from the list (the first entries are expected to be the closest mirrors to your location). 3) The directory holding the distribution sets. The default value of pub/OpenBSD/5.6/alpha is almost always correct on FTP servers; for HTTP servers there is no standard location for this. 4) For FTP installs only, the login and password for the FTP account. You will only be asked for a password for non-anonymous FTP. Then refer to the section named "installation set selection" below. 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". If there is more than one partition on the CD-ROM, you will be asked which partition the distribution is to be loaded from. This is normally partition "a". You will also have to provide the relative path to the directory on the CD-ROM which holds the distribution, for the alpha this is "5.6/alpha". Then refer to the section named "installation set selection" below. To install from a local disk partition: When installing from a local disk partition, you will first have to identify which disk holds the distribution sets. This is normally "wdN" or "sdN", where N is a number. Next you will have to identify the partition within that disk that holds the distribution; this is a single letter between 'a' and 'p'. You will also have to identify the type of file system residing in the partition identified. Currently, you can only install from partitions that have been formatted as the Berkeley fast file system (ffs). 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 '/'. Then refer to the next section. Installation set selection: A list of available distribution sets found on the given location will be listed. You may individually select distribution sets to install, by entering their name, or wildcards (e.g. `*.tgz' or `base*|comp*', or `all' to select all the sets (which is what most users will want to do). You may also enter `abort' to deselect everything and restart the selection from scratch, or unselect sets by entering their name prefixed with `-' (e.g. `-x*'). It is also possible to enter an arbitrary filename and have it treated as a file set. When you are done selecting distribution sets, enter `done'. The files will begin to extract. After the files have been extracted, you will be given the choice to select a new location from which to install distribution sets. If there have been errors extracting the sets from the previous location, or if some sets have been missing, this allows you to select a better source. Also, if the installation program complains that the distribution sets you have been using do not match their recorded checksums, you might want to check your installation source (although this can happen between releases, if a snapshot is being updated on an FTP or HTTP server with newer files while you are installing). The last thing you might need to configure, if you did not get the chance to earlier, is the time zone your system will be using. For this work properly, it is expected that you have installed at least the "base56", "etc56", and "bsd" distribution sets. The installation program will then proceed to save the system configuration, create all the device nodes needed by the installed system, and will install bootblocks on the root disk. On multiprocessor systems, if the bsd.mp kernel has been installed, it will be renamed to `bsd', which is the default kernel the boot blocks look for. The single processor kernel, `bsd', will be available as `bsd.sp'. Finally, you will be asked whether you would like to install non-free firmware files (which can't be tightly integrated to the OpenBSD system) on first boot, by invoking fw_update(8) on the next boot. Congratulations, you have successfully installed OpenBSD 5.6. 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 5.6 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. Preparing an unattended installation of OpenBSD: ------------------------------------------------ If the installation system detects that it booted from the network, and isn't interrupted within 5 seconds, it attempts a fully-automatic installation. In this mode the installer runs dhclient(8) on the network interface the system booted from, or in case of multiple interfaces it will ask which one to use. Upon success it retrieves a response file via HTTP. The "next-server" DHCP option specifies the hostname part of the URL, as in "http:///install.conf". The "filename" DHCP parameter specifies the installer mode, e.g. "auto_install". On architectures where this parameter is used for netbooting, create a symbolic link named "auto_install" pointing to the boot program. The response file contains lines with key/value pairs separated by an equals sign '=', where the key is a non-ambiguous part (up to the question mark) of the installer question, consisting of whitespace separated words. The value is what would have been entered at the interactive prompt. Empty lines and lines beginning with a '#' character are ignored. The installer uses default answers in case of missing answers. Here is a response file example that uses a hashed password (see encrypt(1) for more details) for root and a public ssh key for the user that is created during the installation. System hostname = openbsd Password for root = $2a$14$Z4xRMg8vDpgYH...GVot3ySoj8yby Setup a user = puffy Password for user = ************* Public ssh key for user = ssh-ed25519 AAAAC3NzaC1...g3Aqre puffy@ai What timezone are you in = Europe/Stockholm Location of sets = http HTTP Server = ftp.eu.openbsd.org The "System hostname" key above matches the following full question asked during an interactive installation: System hostname? (short form, e.g. 'foo') While the installation is in progress the installer writes all output to the file /ai.log, which is available as mail on the freshly installed system after the initial reboot. If the installation is successful the system will reboot automatically; otherwise, you will be dropped back into the shell where you can look at the /ai.log file or try again. Upgrading a previously-installed OpenBSD System: ------------------------------------------------ Warning! Upgrades to OpenBSD 5.6 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. As a minimum, if the toolchain (the ``comp'' set) was installed, you should remove all files within /usr/include before attempting to upgrade. To upgrade OpenBSD 5.6 from a previous version, start with the general instructions in the section "Installing OpenBSD". Boot from the CD-ROM or an installation floppy. When prompted, select the (U)pgrade option rather than the (I)nstall option at the prompt in the install process. You will be presented with a welcome message and asked if you really wish to upgrade. 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 neither the ``etc56.tgz'' nor the ``xetc56.tgz'' sets, 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 etc56.tgz and xetc56.tgz sets in a temporary directory and merge changes by hand, or with the help of the sysmerge(8) helper script, 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, CVSync or FTP. For more information, see http://www.OpenBSD.org/anoncvs.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) Use the OpenBSD ``package'' collection to grab a pre-compiled and tested version of the application for your hardware. 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) Obtain the source code and build the application based upon whatever installation procedures are provided with the application. If you purchased the OpenBSD CD-ROM set you already have a few 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 the most commonly installed third-party applications pre-built for various hardware architectures. Limited disk space on the CD-ROM unfortunately limits the number of such packages. Check the directory 5.6/packages/alpha 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/5.6/packages/alpha/ # # umount /cdrom Package names are usually the application name and version with .tgz appended, e.g. bzip2-1.0.6p0.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/5.6/packages/alpha/ 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/5.6/packages/alpha/emacs-21.4p23.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/faq/ports/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 look at the FreeBSD ports or NetBSD pkgsrc for inspiration. 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 in the OpenBSD Porter's Handbook at http://www.openbsd.org/faq/ports/ 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. More information about the various OpenBSD mailing list and proper netiquette is available at http://www.OpenBSD.org/mail.html 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 As a favor, please avoid mailing huge documents or files to the mailing lists. Instead, put the material you would have sent on a web server, 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.
