45:
46: <p>
1.1 deraadt 47: OpenBSD looks a lot like NetBSD (which it is derived from, following
48: the 4.4BSD roots), but is now being developed seperately. Good changes
49: from other free operating systems will be merged in (of course, depending
1.24 deraadt 50: on various factors like developer time for example.) OpenBSD tracks
51: NetBSD changes very closely; say anywhere between 2 days to 10 days
52: behind the state of NetBSD-current all the time. Hence you can truly
53: say that OpenBSD is NetBSD <b>PLUS MORE STUFF</b>.
1.18 fn 54: </p>

56: <p>
1.22 deraadt 57: Various additions have been made. This is only a small partial list of
1.25 deraadt 58: the major machine independent changes (ie. it is the most interesting
59: changes or what people ask about most often). Check the specific port
60: you are interested in for further details of that port -- many of them
61: have been extended too.

425: <strong>IMPORTANT NOTE:</strong>
426: There are a few issues relating to cryptographic software that everyone
427: should be aware of:
428: <ul>
1.20 deraadt 429: <li>The OpenBSD sources are from Canada.
430: <a href=http://insight.mcmaster.ca/org/efc/pages/doc/crypto-export.html>It
431: is legal to export crypto software from Canada to the world.</a>
1.21 deraadt 432: <p>
1.1 deraadt 433: <li>However, if you are outside the USA or Canada, you should not
1.5 deraadt 434: fetch the cryptographic sections of the OpenBSD sources from an
435: anoncvs server located in the USA. The files in question are...
1.1 deraadt 436: <ul>
437: <li>src/kerberosIV/*
438: <li>src/lib/libc/crypt/crypt.c
439: <li>src/lib/libc/crypt/morecrypt.c
440: </ul>
441: Because of the USA ITAR munitions list,
442: crypto software may only be exported to Canada from the USA.
1.21 deraadt 443: <p>
1.58 deraadt 444: <li>The OpenBSD project is looking for more anoncvs servers -- read
445: on to find out how you can help.
1.1 deraadt 446: </ul>
1.18 fn 447: </p>
448:
1.1 deraadt 449: <p>
1.5 deraadt 450: A sample use of an anoncvs CVS server would be:
1.1 deraadt 451: <pre>
1.12 deraadt 452: % setenv CVSROOT anoncvs@anoncvs.usa.openbsd.org:/cvs
1.1 deraadt 453: % cd /tmp
1.58 deraadt 454: % cvs get src/sys/arch/sparc
1.1 deraadt 455: [copies the files from the repository to your machine]
1.58 deraadt 456: % cvs log src/sys/arch/sparc/sparc/locore.s
1.1 deraadt 457: [shows the commit log for the chosen file ]
1.58 deraadt 458: % cvs diff -bc -r1.1 -r1.5 src/sys/arch/sparc/sparc/locore.s
1.1 deraadt 459: [shows the changes between revisions 1.1 and rev 1.5]
460: </pre>
1.18 fn 461: </p>
462:
463: <p>
1.44 deraadt 464: Here is how someone using anoncvs regularily would update his
465: source tree:
466: <pre>
467: # setenv CVSROOT anoncvs@anoncvs.usa.openbsd.org:/cvs
468: # cd /usr
469: # cvs -q get -PA src
470: </pre>
471: or similarily later on he might try
472: <pre>
473: # cd /usr/src
474: # cvs -q up -PAd
475: </pre>
1.58 deraadt 476: Everytime you ran this it would syncronize your /usr/src tree. It would
477: not destroy any of your local changes, rather it would attempt to merge
478: changes in. If you use obj directories (not obj symbolic links) you may
479: wish to append "-I obj" to the cvs command line, this will keep cvs from
480: spitting out a warning about all the obj directories it is going to
481: encounter which are not in the repository.
1.44 deraadt 482: </p>
483:
484: <p>
1.1 deraadt 485: The CVS man page (included with the CVS sources) has much more
1.18 fn 486: information about how CVS can be used.
487: </p>
488:
1.1 deraadt 489: <p>
490: The anoncvs service gives fledgling developers a chance to learn CVS
491: operation and get thoroughly involved in the development process
492: before getting "commit" access -- as a result of showing useful
493: skills and high quality results they will naturally later be given
1.18 fn 494: developer access. As well, people providing patches can create
495: their "diff"s relative to the CVS tree, which will ease integration.
496: </p>
497:
498: <p>
499: The CVS client uses rsh to talk to the CVS server. If some local
500: security measure like a firewall (or imperfect protocol emulators
501: like slirp) prevents you from using rsh, you may be able to use
1.58 deraadt 502: <a href=http://www.cs.hut.fi/ssh>ssh</a> instead. In this case,
503: one sets the environment variable <strong>CVS_RSH</strong> to point
504: to ssh (typically <strong>/usr/local/bin/ssh</strong>). To reduce the
505: performance hit the anoncvs server would take it is recommended (and
506: requested) that you disable encryption. If your local site prevents
507: you from connecting out to port 22 (which ssh defaults to using) use
508: port 2022.

1.1 deraadt 512: Do not be tempted to turn on compression since CVS already compresses.
513: Use something like the following in your <strong>$HOME/.ssh/config</strong>

1.71 deraadt 523: CVS is a little noisy starting up; to quiet it a bit you may want to
524: do this:

1.18 fn 531: If you wish to be a new anoncvs mirror site, please contact the anoncvs
532: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.16 deraadt 533: Anoncvs mirrors require about 300MB of disk, and use up to 4MB of swap
1.1 deraadt 534: per anoncvs user (assuming the user does a large operation; while smaller
535: operations use fewer resources, anoncvs still makes much more of an
1.18 fn 536: impact than ftp or sup). Such anoncvs machines should have excellent
537: network connectivity for the area they are expected to serve. A
538: <a href=anoncvs.shar>document</a>
539: which describes the setup of anoncvs servers is available.
