46:
47: <p>
1.1 deraadt 48: OpenBSD looks a lot like NetBSD (which it is derived from, following
49: the 4.4BSD roots), but is now being developed seperately. Good changes
50: from other free operating systems will be merged in (of course, depending
1.24 deraadt 51: on various factors like developer time for example.) OpenBSD tracks
52: NetBSD changes very closely; say anywhere between 2 days to 10 days
53: behind the state of NetBSD-current all the time. Hence you can truly
54: say that OpenBSD is NetBSD <b>PLUS MORE STUFF</b>.
1.18 fn 55: </p>
1.1 deraadt 56:
57: <p>
1.22 deraadt 58: Various additions have been made. This is only a small partial list of
1.25 deraadt 59: the major machine independent changes (ie. it is the most interesting
60: changes or what people ask about most often). Check the specific port
61: you are interested in for further details of that port -- many of them
62: have been extended too.
1.1 deraadt 63: <ul>
1.35 deraadt 64: <li>Many many NetBSD PR's fixed (which NetBSD has not yet fixed)

1.22 deraadt 68: <li>ipfilter for filtering dangerous packets
69: <li>better ELF support

1.38 deraadt 89: <li>pax as tar, gnutar is toast
1.42 deraadt 90: <li>using AT&T awk, gawk is toast
1.38 deraadt 91: <li>Even more security fixes.
1.47 deraadt 92: <li>Accepts FreeBSD MD5 passwords in password maps, soon will be able to
93: generate them too
1.40 deraadt 94: <li>Linux ext2fs and BSD4.4 LFS support being worked on.
1.65 deraadt 95: <li>Working ATAPI audio support for multiple architectures.

1.75 deraadt 136: Note: for some of these platforms, the platform-dependent code may
1.1 deraadt 137: be identical to that found in NetBSD because there isn't a specific
1.75 deraadt 138: OpenBSD developer. For other ports the differences are significant.
1.1 deraadt 139: If you find an empty page that means nothing of consequence that is
1.75 deraadt 140: directly port-specific has changed from NetBSD. (Of course there are
1.1 deraadt 141: differences, but they just aren't in the /sys/arch/XXXX directory).

401: <strong>IMPORTANT NOTE:</strong>
402: There are a few issues relating to cryptographic software that everyone
403: should be aware of:
404: <ul>
1.20 deraadt 405: <li>The OpenBSD sources are from Canada.
406: <a href=http://insight.mcmaster.ca/org/efc/pages/doc/crypto-export.html>It
407: is legal to export crypto software from Canada to the world.</a>
1.21 deraadt 408: <p>
1.1 deraadt 409: <li>However, if you are outside the USA or Canada, you should not
1.5 deraadt 410: fetch the cryptographic sections of the OpenBSD sources from an
411: anoncvs server located in the USA. The files in question are...
1.1 deraadt 412: <ul>
413: <li>src/kerberosIV/*
414: <li>src/lib/libc/crypt/crypt.c
415: <li>src/lib/libc/crypt/morecrypt.c
416: </ul>
417: Because of the USA ITAR munitions list,
418: crypto software may only be exported to Canada from the USA.
1.21 deraadt 419: <p>
1.58 deraadt 420: <li>The OpenBSD project is looking for more anoncvs servers -- read
421: on to find out how you can help.

1.5 deraadt 426: A sample use of an anoncvs CVS server would be:
1.1 deraadt 427: <pre>
1.12 deraadt 428: % setenv CVSROOT anoncvs@anoncvs.usa.openbsd.org:/cvs
1.1 deraadt 429: % cd /tmp
1.58 deraadt 430: % cvs get src/sys/arch/sparc
1.1 deraadt 431: [copies the files from the repository to your machine]
1.58 deraadt 432: % cvs log src/sys/arch/sparc/sparc/locore.s
1.1 deraadt 433: [shows the commit log for the chosen file ]
1.58 deraadt 434: % cvs diff -bc -r1.1 -r1.5 src/sys/arch/sparc/sparc/locore.s
1.1 deraadt 435: [shows the changes between revisions 1.1 and rev 1.5]
436: </pre>
1.18 fn 437: </p>
438:
439: <p>
1.44 deraadt 440: Here is how someone using anoncvs regularily would update his
441: source tree:
442: <pre>
443: # setenv CVSROOT anoncvs@anoncvs.usa.openbsd.org:/cvs
444: # cd /usr
445: # cvs -q get -PA src
446: </pre>
447: or similarily later on he might try
448: <pre>
449: # cd /usr/src
450: # cvs -q up -PAd
451: </pre>
1.58 deraadt 452: Everytime you ran this it would syncronize your /usr/src tree. It would
453: not destroy any of your local changes, rather it would attempt to merge
454: changes in. If you use obj directories (not obj symbolic links) you may
455: wish to append "-I obj" to the cvs command line, this will keep cvs from
456: spitting out a warning about all the obj directories it is going to
457: encounter which are not in the repository.
1.44 deraadt 458: </p>
459:
460: <p>
1.1 deraadt 461: The CVS man page (included with the CVS sources) has much more
1.18 fn 462: information about how CVS can be used.
463: </p>
464:
1.1 deraadt 465: <p>
466: The anoncvs service gives fledgling developers a chance to learn CVS
467: operation and get thoroughly involved in the development process
468: before getting "commit" access -- as a result of showing useful
469: skills and high quality results they will naturally later be given
1.18 fn 470: developer access. As well, people providing patches can create
471: their "diff"s relative to the CVS tree, which will ease integration.
472: </p>
473:
474: <p>
475: The CVS client uses rsh to talk to the CVS server. If some local
476: security measure like a firewall (or imperfect protocol emulators
477: like slirp) prevents you from using rsh, you may be able to use
1.58 deraadt 478: <a href=http://www.cs.hut.fi/ssh>ssh</a> instead. In this case,
479: one sets the environment variable <strong>CVS_RSH</strong> to point
480: to ssh (typically <strong>/usr/local/bin/ssh</strong>). To reduce the
481: performance hit the anoncvs server would take it is recommended (and
482: requested) that you disable encryption. If your local site prevents
483: you from connecting out to port 22 (which ssh defaults to using) use
484: port 2022.

1.1 deraadt 488: Do not be tempted to turn on compression since CVS already compresses.
489: Use something like the following in your <strong>$HOME/.ssh/config</strong>
490: file.

1.18 fn 497:
498: <p>
1.71 deraadt 499: CVS is a little noisy starting up; to quiet it a bit you may want to
500: do this:
501: <pre>
502: setenv CVS_CLIENT_PORT -1
503: </pre>

1.18 fn 507: If you wish to be a new anoncvs mirror site, please contact the anoncvs
508: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.16 deraadt 509: Anoncvs mirrors require about 300MB of disk, and use up to 4MB of swap
1.1 deraadt 510: per anoncvs user (assuming the user does a large operation; while smaller
511: operations use fewer resources, anoncvs still makes much more of an
1.18 fn 512: impact than ftp or sup). Such anoncvs machines should have excellent
513: network connectivity for the area they are expected to serve. A
514: <a href=anoncvs.shar>document</a>
515: which describes the setup of anoncvs servers is available.
