INSTALLATION NOTES for OpenBSD/MACHINE 2.1 What is OpenBSD? ---------------- OpenBSD is a Berkeley Networking Release 2 (Net/2) and 4.4BSD-Lite -derived Operating System. It is a fully functional UN*X-like system which runs on many architectures and is being ported to more. Continuing the multi-platform tradition, OpenBSD has added ports to mvme68k and arc machines. Kernel interfaces have continued to be refined, and now several subsystems and device drivers are shared among the different ports. You can look for this trend to continue. Security of the system as a whole has been significantly improved. Source code for all critical system components has been checked for remote-access, local-access, denial-of-service, data destruction, or information-gathering problems. OpenBSD 2.1 has significantly enhanced the binary emulation subsystem (which includes iBCS2, Linux, OSF/1, SunOS, SVR4, Solaris and Ultrix compatibility) and several kernel subsystems have been generalized to support this more readily. The binary emulation strategy is aimed at making the emulation as accurate as possible. Cryptography components are part of OpenBSD. OpenBSD is from Canada, and export of these pieces (such as kerberosIV) to the world is not restricted. Many new user programs have been added in OpenBSD 2.1, as well, bringing it closer to our goal of supplying a complete UN*X-like environment. Tools like perl and ksh are standard, as are numerous other useful tools. #include "whatis" Sources of OpenBSD: ------------------- #include "mirrors" OpenBSD 2.1 Release Contents: ----------------------------- The OpenBSD 2.1 release is organized in the following way: .../2.1/ src/ Source distribution sets; see below. In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures that OpenBSD 2.1 has a binary distribution for. (That is described further along in this document). The source distribution sets can be found in subdirectories of the "source" subdirectory of the distribution tree. They contain the complete sources to the system. The source distribution sets are as follows: gsrc21 This set contains the "gnu" sources, including the source for the compiler, assembler, groff, and the other GNU utilities in the binary distribution sets. [ 7.1M gzipped, 30.4M uncompressed ] ksrc21 This set contains the sources to the OpenBSD 2.1 kernel, config(8), config.old(8) and dbsym(8). [ 6.0M gzipped, 27.0M uncompressed ] ssrc21 This set contains the "share" sources, which include the sources for the man pages not associated with any particular program, the sources for the typesettable document set, the dictionaries, and more. [ 2.4M gzipped, 8.9M uncompressed ] src21 This set contains all of the OpenBSD 2.1 sources which are not mentioned above. [ 9.3M gzipped, 41.6M uncompressed ] It is worth noting that unless all of the source distribution sets are installed (except the domestic set), you can't rebuild and install the system from scratch, straight out of the box. However, all that is required to rebuild the system in that case is a trivial modification to one Makefile. The source distribution sets are distributed as groups of files named "set_name.xx" where "set_name" is the distribution set name, and "xx" is the sequence number of the file, starting with "aa" for the first file in the distribution set, then "ab" for the next, and so on. All of these files except the last one of each set should be exactly 240,640 bytes long. (The last file is just long enough to contain the remainder of the data for that distribution set.) Catted together, the files belonging to a source distribution set comprise a gzipped tar file. If you want to look at list of the files contained in the set, you could use the command: cd /usr/src; cat set_name.?? | tar tvfz - or to actually extract the files contained in the set: cd /usr/src; cat set_name.?? | tar xfpz - In each of the source distribution set directories, there are two files named "CKSUMS" and "MD5" which contain the checksums of the files in that directory, as generated by the cksum(1) and md5(1) utilities respectively. If you suspect that one of the files is corrupt and have access to a cksum or md5 binary, you can compare their output to the "CKSUMS" or "MD5" file. #include "contents" OpenBSD System Requirements and Supported Devices: -------------------------------------------------- #include "hardware" Getting the OpenBSD System on to Useful Media: ---------------------------------------------- #include "xfer" Preparing your System for OpenBSD Installation: ----------------------------------------------- #include "prep" Installing the OpenBSD System: ------------------------------ #include "install" Upgrading a previously-installed OpenBSD System: ------------------------------------------------ #include "upgrade" Using online OpenBSD documentation: ----------------------------------- Documentation is available if you first install the manual distribution set. Traditionally, the UN*X "man pages" (documentation) are denoted by 'name(section)'. Some examples of this are intro(1), man(1), apropros(1), passwd(1), and passwd(5). The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative information is in section 8. The 'man' command is used to view the documentation on a topic, and is started by entering 'man [section] topic'. The brackets [] around the section should not be entered, but rather indicate that the section is optional. If you don't ask for a particular section, the topic with the 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. 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. 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. There are also port-specific mailing lists, to discuss aspects of each port of OpenBSD. Use majordomo to find their addresses. If you're interested in doing a serious amount of work on a specific port, you probably should contact the "owner" of that port (listed below). As a favor, please avoid mailing huge documents or files to these 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.
