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>.

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.

417: <strong>IMPORTANT NOTE:</strong>
418: There are a few issues relating to cryptographic software that everyone
419: should be aware of:
420: <ul>
1.20 deraadt 421: <li>The OpenBSD sources are from Canada.
422: <a href=http://insight.mcmaster.ca/org/efc/pages/doc/crypto-export.html>It
423: is legal to export crypto software from Canada to the world.</a>
1.21 deraadt 424: <p>
1.1 deraadt 425: <li>However, if you are outside the USA or Canada, you should not
1.5 deraadt 426: fetch the cryptographic sections of the OpenBSD sources from an
427: anoncvs server located in the USA. The files in question are...
1.1 deraadt 428: <ul>
429: <li>src/kerberosIV/*
430: <li>src/lib/libc/crypt/crypt.c
431: <li>src/lib/libc/crypt/morecrypt.c
432: </ul>
433: Because of the USA ITAR munitions list,
434: crypto software may only be exported to Canada from the USA.
1.21 deraadt 435: <p>
1.58 deraadt 436: <li>The OpenBSD project is looking for more anoncvs servers -- read
437: on to find out how you can help.

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

1.1 deraadt 504: Do not be tempted to turn on compression since CVS already compresses.
505: Use something like the following in your <strong>$HOME/.ssh/config</strong>

1.71 deraadt 515: CVS is a little noisy starting up; to quiet it a bit you may want to
516: do this:

1.18 fn 523: If you wish to be a new anoncvs mirror site, please contact the anoncvs
524: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.16 deraadt 525: Anoncvs mirrors require about 300MB of disk, and use up to 4MB of swap
1.1 deraadt 526: per anoncvs user (assuming the user does a large operation; while smaller
527: operations use fewer resources, anoncvs still makes much more of an
1.18 fn 528: impact than ftp or sup). Such anoncvs machines should have excellent
529: network connectivity for the area they are expected to serve. A
530: <a href=anoncvs.shar>document</a>
531: which describes the setup of anoncvs servers is available.
