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)

1.1 deraadt 147: be identical to that found in NetBSD because there isn't a specific
1.75 deraadt 148: OpenBSD developer. For other ports the differences are significant.
1.1 deraadt 149: If you find an empty page that means nothing of consequence that is
1.75 deraadt 150: directly port-specific has changed from NetBSD. (Of course there are

411: <strong>IMPORTANT NOTE:</strong>
412: There are a few issues relating to cryptographic software that everyone
413: should be aware of:
414: <ul>
1.20 deraadt 415: <li>The OpenBSD sources are from Canada.
416: <a href=http://insight.mcmaster.ca/org/efc/pages/doc/crypto-export.html>It
417: is legal to export crypto software from Canada to the world.</a>
1.21 deraadt 418: <p>
1.1 deraadt 419: <li>However, if you are outside the USA or Canada, you should not
1.5 deraadt 420: fetch the cryptographic sections of the OpenBSD sources from an
421: anoncvs server located in the USA. The files in question are...
1.1 deraadt 422: <ul>
423: <li>src/kerberosIV/*
424: <li>src/lib/libc/crypt/crypt.c
425: <li>src/lib/libc/crypt/morecrypt.c
426: </ul>
427: Because of the USA ITAR munitions list,
428: crypto software may only be exported to Canada from the USA.

1.5 deraadt 436: A sample use of an anoncvs CVS server would be:
1.1 deraadt 437: <pre>
1.12 deraadt 438: % setenv CVSROOT anoncvs@anoncvs.usa.openbsd.org:/cvs
1.1 deraadt 439: % cd /tmp
1.58 deraadt 440: % cvs get src/sys/arch/sparc
1.1 deraadt 441: [copies the files from the repository to your machine]
1.58 deraadt 442: % cvs log src/sys/arch/sparc/sparc/locore.s
1.1 deraadt 443: [shows the commit log for the chosen file ]
1.58 deraadt 444: % cvs diff -bc -r1.1 -r1.5 src/sys/arch/sparc/sparc/locore.s
1.1 deraadt 445: [shows the changes between revisions 1.1 and rev 1.5]
446: </pre>
1.18 fn 447: </p>
448:
449: <p>
1.44 deraadt 450: Here is how someone using anoncvs regularily would update his
451: source tree:
452: <pre>
453: # setenv CVSROOT anoncvs@anoncvs.usa.openbsd.org:/cvs
454: # cd /usr
455: # cvs -q get -PA src
456: </pre>
457: or similarily later on he might try
458: <pre>
459: # cd /usr/src
460: # cvs -q up -PAd
461: </pre>
1.58 deraadt 462: Everytime you ran this it would syncronize your /usr/src tree. It would
463: not destroy any of your local changes, rather it would attempt to merge
464: changes in. If you use obj directories (not obj symbolic links) you may
465: wish to append "-I obj" to the cvs command line, this will keep cvs from
466: spitting out a warning about all the obj directories it is going to
467: encounter which are not in the repository.
1.44 deraadt 468: </p>
469:
470: <p>
1.1 deraadt 471: The CVS man page (included with the CVS sources) has much more
1.18 fn 472: information about how CVS can be used.
473: </p>
474:
1.1 deraadt 475: <p>
476: The anoncvs service gives fledgling developers a chance to learn CVS
477: operation and get thoroughly involved in the development process
478: before getting "commit" access -- as a result of showing useful
479: skills and high quality results they will naturally later be given
1.18 fn 480: developer access. As well, people providing patches can create
481: their "diff"s relative to the CVS tree, which will ease integration.
482: </p>
483:
484: <p>
485: The CVS client uses rsh to talk to the CVS server. If some local
486: security measure like a firewall (or imperfect protocol emulators
487: like slirp) prevents you from using rsh, you may be able to use
1.58 deraadt 488: <a href=http://www.cs.hut.fi/ssh>ssh</a> instead. In this case,
489: one sets the environment variable <strong>CVS_RSH</strong> to point
490: to ssh (typically <strong>/usr/local/bin/ssh</strong>). To reduce the
491: performance hit the anoncvs server would take it is recommended (and
492: requested) that you disable encryption. If your local site prevents
493: you from connecting out to port 22 (which ssh defaults to using) use
494: port 2022.

1.1 deraadt 498: Do not be tempted to turn on compression since CVS already compresses.
499: Use something like the following in your <strong>$HOME/.ssh/config</strong>

1.71 deraadt 509: CVS is a little noisy starting up; to quiet it a bit you may want to
510: do this:

1.18 fn 517: If you wish to be a new anoncvs mirror site, please contact the anoncvs
518: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.16 deraadt 519: Anoncvs mirrors require about 300MB of disk, and use up to 4MB of swap
1.1 deraadt 520: per anoncvs user (assuming the user does a large operation; while smaller
521: operations use fewer resources, anoncvs still makes much more of an
1.18 fn 522: impact than ftp or sup). Such anoncvs machines should have excellent
523: network connectivity for the area they are expected to serve. A
524: <a href=anoncvs.shar>document</a>
525: which describes the setup of anoncvs servers is available.
