INSTALLATION NOTES for OpenBSD/landisk 4.6 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. To integrate more smoothly in other environments, OpenBSD 4.6 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 4.6 release is available on the web at http://www.OpenBSD.org/46.html. OpenBSD/landisk runs on various network appliances based on an IO-DATA design with an Hitachi/Renesas SuperH CPU.

If you wish to become a distribution site for OpenBSD, contact . OpenBSD 4.6 Release Contents: ----------------------------- The OpenBSD 4.6 release is organized in the following way. In the .../4.6 directory, for each of the architectures having an OpenBSD 4.6 binary distribution, there is a sub-directory. The landisk-specific portion of the OpenBSD 4.6 release is found in the "landisk" subdirectory of the distribution. That subdirectory is laid out as follows: .../4.6/landisk/ INSTALL.landisk 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. miniroot46.fs A miniroot filesystem image to be copied to the beginning of the disk to allow installing OpenBSD 4.6. *.tgz landisk binary distribution sets; see below. bsd A stock GENERIC landisk kernel which will be installed on your system during the install. bsd.rd A compressed RAMDISK kernel; the embedded filesystem contains the installation tools. Used for simple installation from a pre-existing system. The OpenBSD/landisk binary distribution sets contain the binaries which comprise the OpenBSD 4.6 release for landisk systems. There are eleven binary distribution sets. The binary distribution sets can be found in the "landisk" subdirectory of the OpenBSD 4.6 distribution tree, and are as follows: base46 The OpenBSD/landisk 4.6 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. [ 45.8 MB gzipped, 129.5 MB uncompressed ] comp46 The OpenBSD/landisk 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. [ 90.8 MB gzipped, 259.1 MB uncompressed ] etc46 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.) [ 499.2 KB gzipped, 1.4 MB uncompressed ] game46 This set includes the games and their manual pages. [ 2.5 MB gzipped, 5.6 MB uncompressed ] man46 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. [ 7.8 MB gzipped, 28.6 MB uncompressed ] misc46 This set includes the system dictionaries (which are rather large), and the typesettable document set. [ 2.7 MB gzipped, 9.4 MB uncompressed ] xbase46 This set includes the base X distribution. This includes programs, headers and libraries. [ 9.9 MB gzipped, 25.9 MB uncompressed ] xetc46 This set includes the X window system configuration files that reside in /etc. It's the equivalent of etc46 for X. [ 74.1 KB gzipped, 275.0 KB uncompressed ] xfont46 This set includes all of the X fonts. [ 33.9 MB gzipped, 41.7 MB uncompressed ] xserv46 This set includes all of the X servers. [ 1.7 MB gzipped, 3.8 MB uncompressed ] xshare46 This set includes all text files equivalent between all architectures. [ 2.6 MB gzipped, 14.0 MB uncompressed ] OpenBSD System Requirements and Supported Devices: -------------------------------------------------- OpenBSD/landisk runs on the following SH4-based IO-DATA made models: IO-DATA USL-5P, using CF storage (Japan) IO-DATA HDL-U, HDL-AV, HDL-W and HDLM-U series (Japan) SuperTank LAN Tank (SOTO-HDLWU) (Japan) IO-DATA UHDL-160U and UHDL-300U (May be found in USA) Plextor PX-EH16L, PX-EH25L and PX-EH40L Supported devices include: Ethernet Adapters ADMtek AN986-based USB adapters, including: Abocom UFE1000 Abocom DSB650TX Accton USB320-EC Accton SpeedStream Ethernet Admtek Pegasus, Pegasus II Billionton Systems USB100 Corega FEther USB-TX D-Link DSB-650, 650TX, 650TX-PNA Elecom LD-USB Elsa Microlink USB2Ethernet I/O Data USB ETTX Kingston KNU101TX Linksys USB100TX, USB100H1 and USB10TA Melco Inc.

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. The variety of options listed may seem confusing, but situations vary widely in terms of what peripherals and what sort of network arrangements a user has, the intent is to provide some way that will be practical. 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 "base46" set somewhere in your file system. It is recommended that you upgrade the other sets, as well. Preparing your System for OpenBSD Installation: ----------------------------------------------- The default configuration of the landisk systems comes with a Linux installation on the disk (either an IDE hard drive, or a CompactFlash card). At the moment, there is no known way to log in this installation as ``root'' or interrupt the boot process, and start an OpenBSD installation procedure. Because of this, the only way to boot the OpenBSD install is to copy the miniroot "miniroot46.fs" image to the hard drive or CompactFlash (on the other hand, upgrades can be started by copying bsd.rd to the OpenBSD disk and booting from it). As a result, you will need another machine to plug the machine's disk or CompactFlash in. Any machine type will do, as long as it supports ATA-compatible storage devices, regardless of the partition scheme it uses. Under OpenBSD, it will appear as a ``wd'' device, for example ``wd1''. Use the dd(1) utility to copy the miniroot to the hard drive. The command would likely be, under OpenBSD: dd if=miniroot46.fs of=/dev/rwd1c Replace ``rwd1c'' with the appropriate device name for the raw device on the system used to do the copy. If the machine has a hard drive, and you had to change jumpers on it to change its ``master'' status, do not forget to configure it back to ``master'' or ``single drive'', as slave drives are not bootable. In addition to the disk preparation, you will need to connect a serial port connector to the machine. Please refer to the OpenBSD/landisk page at http://www.OpenBSD.org/landisk.html for more information. 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. The installation procedure is designed to gather as many 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). If you have copied the miniroot image to the disk, it will boot automatically upon power-up. 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 "wd0". 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. After the kernel is done initialization, 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 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 sollicitation 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 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. 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. Disks on OpenBSD/landisk are partitioned using the so-called ``MBR'' partitioning scheme. You will need to create one MBR partition, in which all the real OpenBSD partitions will be created. The installation program will ask you if you want to use the whole disk for OpenBSD. If you don't need to or don't intend to share the disk with other operating systems, answer `w' here. The installation program will then create a single MBR partition spanning the whole disk, dedicated to OpenBSD. Otherwise, fdisk(8) will be invoked to let you to edit your MBR partitioning. The current MBR partitions defined will be displayed and you will be allowed to modify them, add new partitions, and change which partition to boot from by default. Note that you should make the OpenBSD partition the active partition at least until the install has been completed. After your OpenBSD MBR partition has been setup, the real partition setup can follow. 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, tape, 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 4.6 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/4.6/landisk 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 landisk this is "4.6/landisk". 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 0 through 9. 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 onlyinstall 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'll need to configure is the time zone your system will be using. For this to work properly, it is expected that you have installed at least the "base46", "etc46", 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. Congratulations, you have successfully installed OpenBSD 4.6. 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 4.6 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. Upgrading a previously-installed OpenBSD System: ------------------------------------------------ Warning! Upgrades to OpenBSD 4.6 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. To upgrade OpenBSD 4.6 from a previous version, start with the general instructions in the section "Installing OpenBSD". Boot from bsd.rd on the boot disk. 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 ``etc46.tgz'' nor the ``xetc46.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 etc46.tgz and xetc46.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, 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 4.6/packages/sh 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/4.6/packages/sh/ # # 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/4.6/packages/sh/ 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/4.6/packages/sh/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 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 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. 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 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.
