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>.

1.1 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 65: <li>New curses library, including libform, libpanel and libmenu.
1.25 deraadt 66: <li>a termlib library which understands termcap.db, needed for new curses.
67: <li>The FreeBSD ports subsystem was integrated and is usable by you!
1.22 deraadt 68: <li>ipfilter for filtering dangerous packets
69: <li>better ELF support
1.25 deraadt 70: <li>nlist() that understands ELF, ECOFF, and a.out, allowing non-a.out ports
71: to use kvm utilies
1.22 deraadt 72: <li>Verbatim integration of the GNU tools (using a wrapper Makefile)
73: <li>All the pieces needed for cross compilation are in the source tree.
74: <li>Some LKM support in the tree.
75: <li>ATAPI support (should work on all ISA busses)
1.25 deraadt 76: <li>new scsi, md5, pkg_* commands
1.22 deraadt 77: <li>Numerous security related fixes
1.25 deraadt 78: <li>Kerberos and other crypto in the source tree that is exportable
79: <li>Solid YP master, server, and client capabilities.
1.22 deraadt 80: <li>/dev/rnd -- source of random data
1.23 deraadt 81: <li>In-kernel update(8) with an adaptive algorithm
1.25 deraadt 82: <li>Some ddb improvements and extensions
83: <li>Numerous scsi fixes
1.28 deraadt 84: <li>new system calls: rfork(), minherit(), poll().
85: <li>select() that can handle any amount of file descriptors.
1.29 deraadt 86: <li>kernfs extensions
87: <li>ATM support (support for one company's sparc & i386 cards available)
1.33 deraadt 88: <li>Boot kernels with "-c" to edit/enable/disable device configuration tables
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.
1.47 deraadt 95: <li>Working ATAPI audio support.
1.51 deraadt 96: <li>terminfo database support.
1.53 deraadt 97: <li>Fortran in the tree.
98: <li>The most secure rdist support anywhere.
99: <li>randomized port allocation from bind() and bindresvport() -- security
100: via unpredictability.
101: <li>Protection from the udp spamming and ftp bounce attacks.
102: <li>Significantly improved ftp daemon.
103: <li>Numerous more security policy and implimentation improvements (OpenBSD
104: defaults to installing in a very secure mode)
105: <li>zlib (non-GPL'd gzip-compatible library)
106: <li>Newest version of ppp, vi,
1.54 deraadt 107: <li>_POSIX_SAVED_IDS behaviour with permitted BSD extensions.

1.1 deraadt 114: Note: for some of these platforms, the platform-independent code may
115: be identical to that found in NetBSD because there isn't a specific
116: OpenBSD developer. For other ports the differences are significant.
117: If you find an empty page that means nothing of consequence that is
118: directly port-specific has changed from NetBSD. (Of course there are
119: differences, but they just aren't in the /sys/arch/XXXX directory).

1.1 deraadt 413: The CVS man page (included with the CVS sources) has much more
1.18 fn 414: information about how CVS can be used.

1.1 deraadt 417: <p>
418: The anoncvs service gives fledgling developers a chance to learn CVS
419: operation and get thoroughly involved in the development process
420: before getting "commit" access -- as a result of showing useful
421: skills and high quality results they will naturally later be given
1.18 fn 422: developer access. As well, people providing patches can create
423: their "diff"s relative to the CVS tree, which will ease integration.
424: </p>
425:
426: <p>
427: The CVS client uses rsh to talk to the CVS server. If some local
428: security measure like a firewall (or imperfect protocol emulators
429: like slirp) prevents you from using rsh, you may be able to use
430: <a href=http://www.cs.hut.fi/ssh>ssh</a>
431: instead (if you are running Solaris, there is a kernel bug which
432: causes problems -- contact
433: <a href=mailto:johns@cs.umr.edu>johns@cs.umr.edu</a>
434: for further details). In this case, one sets the environment
435: variable <strong>CVS_RSH</strong> to point to ssh (typically
436: <strong>/usr/local/bin/ssh</strong>). To reduce the performance
437: hit the anoncvs server would take it is recommended (and requested)
438: that you disable encryption. If your local site prevents you from
439: connecting out to port 22 (which ssh defaults to using) use port 2022.
440: </p>
1.5 deraadt 441:
442: <p>
1.1 deraadt 443: Do not be tempted to turn on compression since CVS already compresses.
444: Use something like the following in your <strong>$HOME/.ssh/config</strong>
445: file.

454: If you wish to be a new anoncvs mirror site, please contact the anoncvs
455: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.16 deraadt 456: Anoncvs mirrors require about 300MB of disk, and use up to 4MB of swap
1.1 deraadt 457: per anoncvs user (assuming the user does a large operation; while smaller
458: operations use fewer resources, anoncvs still makes much more of an
1.18 fn 459: impact than ftp or sup). Such anoncvs machines should have excellent
460: network connectivity for the area they are expected to serve. A
461: <a href=anoncvs.shar>document</a>
462: which describes the setup of anoncvs servers is available.
