Stephan Rickauer has announced the release of BSDanywhere 4.5, a live CD consisting of a base OpenBSD system plus a graphical desktop (Enlightenment 17): "We are pleased to announce the immediate availability of BSDanywhere 4.5 - Enlightenment at your fingertips. Here's a quick summary of the changes since 4.4: Upgrade base system to OpenBSD 4.5 and packages accordingly, please see the OpenBSD site for a list of changes since 4.4; contains official, standard, unmodified OpenBSD kernel - previously, we had to ship a slightly modified version of the OpenBSD kernel to make the boot off CD media less cumbersome, but thanks to OpenBSD developer Kenneth Westerback, this has been improved in OpenBSD 4.5; last but not least, we have great new artwork, provided graciously by Tim Saueressig." Here is the complete release announcement. Download (SHA256): bsdanywhere45-i386.iso (628MB), bsdanywhere45-amd64.iso (699MB).

BSDanywhere是基于OpenBSD的自启动运行光盘镜像。它包含了整个OpenBSD基础系统（不含编译器），并带有一份图形桌面、一套非典型 的软件收藏、自动硬件检测，以及对很多显示卡、声卡、SCSI、USB设备及其他外设的支持。BSDanywhere可以作为一份教学UNIX系统，一套 修复环境，或者是硬件测试平台来使用。

Pre-orders are now being accepted for OpenBSD 4.5, scheduled for release on May 1st, 2009.

The developers bring us an amazing amount of cool new stuff (Accelerated video drivers, OpenSSH 5.2, LDoms Virtualization, pflow(4) NetFlow export interface, aucat(8) audio server capability and lots more). There are over 5500 ports and packages for easy installation.

Of course, t-shirts and posters are available too. Order your set NOW! (International, Europe)

    Some exploitable logic errors have been discovered in OpenSSL versions prior to 0.9.8j.
    These errors may permit an attacker to bypass validation of DSA/ECDSA certificates and
    conduct a "man in the middle attack" against SSL/TLS connection that use them.
    Fortunately, DSA and ECDSA certificates appear to be rarely used in practice.

    This vulnerability has been designated CVE-2008-5077.
    More information is available from the OpenSSL project at:

        http://www.openssl.org/news/secadv_20090107.txt

    Source code patches are available for OpenBSD 4.3 and 4.4. -current has been updated to OpenSSL 0.9.8j

    Patch for OpenBSD 4.3:

        ftp://ftp.openbsd.org/pub/OpenBSD/patches/4.3/common/007_openssl.patch

    Patch for OpenBSD 4.4:

        ftp://ftp.openbsd.org/pub/OpenBSD/patches/4.4/common/007_openssl.patch

    These patches are also available in the OPENBSD_4_3 and OPENBSD_4_4 stable CVS branches.

Thanks Damien for the update. Start your patching!

LOCKSPOOL(1)               OpenBSD Reference Manual               LOCKSPOOL(1)

NAME
     lockspool - lock user's system mailbox

SYNOPSIS
     lockspool [username]

DESCRIPTION
     lockspool is useful for a client mail program to attain proper locking.
     lockspool obtains a username.lock for the calling user and retains it un-
     til stdin is closed or a signal like SIGINT, SIGTERM, or SIGHUP is re-
     ceived.  Additionally, the superuser may specify the name of a user in
     order to lock a different mailbox.

     If lockspool is able to create the lock file, ``1'' is written to stdout,
     otherwise ``0'' is written and an error message is written to stderr.
     lockspool will try up to 10 times to get the lock (sleeping for a short
     period in between tries).

     The lockspool utility exits 0 on success, and 1 if an error occurs.

FILES
     /var/mail/username.lock  user's mail lock file

SEE ALSO
     mail(1), mail.local(8), sendmail(8)

HISTORY
     The lockspool program appeared in OpenBSD 2.4.

NOLOGIN(8)              OpenBSD System Manager's Manual             NOLOGIN(8)

NAME
     nologin - politely refuse a login

SYNOPSIS
     nologin

DESCRIPTION
     nologin displays a message that an account is not available and exits
     non-zero.  It is intended as a replacement shell field for accounts that
     have been disabled.

     If the file /etc/nologin.txt exists, nologin displays its contents to the
     user instead of the default message.

SEE ALSO
     login(1)

HISTORY
     The nologin command appeared in 4.4BSD.

Stephan Rickauer has announced the release of BSDanywhere 4.4, a live CD based on the latest stable version of OpenBSD: "We are pleased to announce the immediate availability of BSDanywhere 4.4 - Enlightenment at your fingertips. As always, we release our OpenBSD based images in two flavours: i386 (32bit) and amd64 (64bit). Here's a quick summary of the not-to-intense changes since 4.3: removed packages: GIMP, AbiWord, Audacious, Mutt, rsnapshot, Darkstat - we are really limited in space that's why we decided to concentrate on the primary focus of BSDanywhere, which is hardware testing and system rescue; added packages: Dnstop, dnstracer; we now enabled 'machdep.kbdreset' which permits console CTRL-ALT-DEL to do a nice halt; new artwork."

INTRO(3)                  OpenBSD Programmer's Manual                 INTRO(3)

NAME
     intro - introduction to the C libraries

SYNOPSIS
     cc [flags] file ...  [-llibrary]

DESCRIPTION
     The manual pages in section 3 provide an overview of the C library func-
     tions, their error returns, and other common definitions and concepts.
     Most of these functions are available from the C library, libc.  Other
     libraries, such as the math library, libm, must be indicated at compile
     time with the -l option of the compiler.

     The various libraries (followed by the loader flag):

     libc (-lc)
             Standard C library functions.  When using the C compiler cc(1),
             it is not necessary to supply the loader flag -lc for these func-
             tions.  There are several ``libraries'' or groups of functions
             included inside of libc: the standard I/O routines, database rou-
             tines, bit operators, string operators, character tests and char-
             acter operators, DES encryption routines, storage allocation,
             time functions, signal handling, and more.

     libcompat (-lcompat)
             Functions which are obsolete but are available for compatibility
             with 4.3BSD.  In particular, a number of system call interfaces
             provided in previous releases of BSD have been included for
             source code compatibility.  Use of these routines should, for the
             most part, be avoided.  The manual page entry for each compati-
             bility routine indicates the proper interface to use.

     libcrypto (-lcrypto)
             The OpenSSL crypto library.  Implements a range of cryptographic
             algorithms, providing such functionality as symmetric encryption,
             public key cryptography, and certificate handling.  See
             crypto(3).

     libcurses (-lcurses)
     libncurses (-lncurses)
     libtermcap (-ltermcap)
     libtermlib (-ltermlib)
             Terminal-independent screen management routines for two-dimen-
             sional non-bitmap display terminals.  This implementation is
             ``new curses'' and is a replacement for 4.2BSD classic curses.
             The libraries libncurses, libtermcap, and libtermlib are all hard
             links to libcurses.  This is for compatibility purposes only; new
             programs should link with -lcurses.  See curses(3) and
             termcap(3).

     libdes (-ldes)
             Implementation of the DES encryption algorithm.  See
             des_crypt(3).

     libedit (-ledit)
             Generic line editing and history functions, similar to those
             found in sh(1).  Functions using the libedit library must be
             linked with the libcurses library, i.e. -ledit -lcurses.  See
             editline(3).

     libevent (-levent)
             Provides a mechanism to execute a function when a specific event
             on a file descriptor occurs or after a given time has passed.
             See event(3).

     libexpat (-lexpat)
             Library routines for parsing XML documents.

     libform (-lform)
             Terminal-independent facilities for composing form screens on
             character-cell terminals.  Functions using the libform library
             must be linked with the libcurses library, i.e. -lform -lcurses.
             See form(3).

     libfrtbegin (-lfrtbegin)
     libg2c (-lg2c)
             Support routines for Fortran functions.  These two libraries were
             separated to allow linking Fortran code with other languages on
             ELF platforms.  See g77(1).

     libgcc (-lgcc)
             GCC runtime support, including long arithmetic, propolice, and
             language independent exception support.  Note: users do not nor-
             mally have to explicitly link with this library.

     libgssapi (-lgssapi)
             The Generic Security Service Application Program Interface
             (GSS-API) provides security services to callers in a generic
             fashion.  See gssapi(3).

     libiberty (-liberty)
             Collection of subroutines missing in other operating systems, as
             well as the C++ demangler and other functions used by the GNU
             toolchain.

     libkadm5clnt (-lkadm5clnt)
             Kerberos administration client library, for talking to a Kerberos
             database.  Clients communicate via the network.

     libkadm5srv (-lkadm5srv)
             Kerberos administration server library, for talking to a Kerberos
             database.  Servers talk directly to the database.

     libkeynote (-lkeynote)
             System library for the keynote trust-management system.  Trust-
             management systems provide standard, general-purpose mechanisms
             for specifying application security policies and credentials.
             Functions using the libkeynote library must be linked with the
             libm and libcrypto libraries, i.e. -lkeynote -lm -lcrypto.  See
             keynote(3) and keynote(4).

     libkrb5 (-lkrb5)
     libasn1 (-lasn1)
     libcom_err (-lcom_err)
     libhdb (-lhdb)
     libkafs (-lkafs)
             Kerberos 5 libraries.  The libraries libasn1, libcom_err, libhdb,
             and libkafs are all hard links to libkrb5.  See krb5(3).

     libkvm (-lkvm)
             Kernel memory interface library.  Provides a uniform interface
             for accessing kernel virtual memory images, including live sys-
             tems and crash dumps.  See kvm(3).

     libl (-ll)
     libfl (-lfl)
             The library for lex(1), a lexical analyzer generator.  The libfl
             library is a hard link to libl.

     libm (-lm)
             Mathematical functions which comprise the C math library, libm.
             See math(3).

     libmenu (-lmenu)
             Terminal-independent facilities for composing menu systems on
             character-cell terminals.  Functions using the libmenu library
             must be linked with the libcurses library, i.e. -lmenu -lcurses.
             See menu(3).

     libmilter (-lmilter)
             The sendmail(8) mail filter API.  See the documentation in

     libotermcap (-lotermcap)
             Routines to provide the user with a method of updating screens
             with reasonable optimisation.  The ocurses(3) library is compati-
             ble with the curses library provided in 4.3.  libotermcap is the
             4.3-compatible termcap library, and is a hard link to libocurses.
             See otermcap(3).

     libossaudio (-lossaudio)
             Provides an emulation of the OSS (Linux) audio interface.  This
             is used only for porting programs.  See ossaudio(3).

     libpanel (-lpanel)
             Terminal-independent facilities for stacked windows on character-
             cell terminals.  Functions using the libpanel library must be
             linked with the libcurses library, i.e. -lpanel -lcurses.  See
             panel(3).

     libpcap (-lpcap)
             Packet capture library.  All packets on the network, even those

LIBRARY TYPES
     The system libraries are located in /usr/lib.  Typically, a library will
     have a number of variants:

           libc.a
           libc.so.30.1
           libc_p.a
           libc_pic.a

     Libraries with an `.a' suffix are static.  When a program is linked
     against a library, all the library code will be linked into the binary.
     This means the binary can be run even when the libraries are unavailable.
     However, it can be inefficient with memory usage.  The C compiler, cc(1),
     can be instructed to link statically by specifying the -static flag.

     Libraries with a `.so.X.Y' suffix are dynamic libraries.  When code is
     compiled dynamically, the library code that the application needs is not
     linked into the binary.  Instead, data structures are added containing
     information about which dynamic libraries to link with.  When the binary
     is executed, the run-time linker ld.so(1) reads these data structures,
     and loads them at a virtual address using the mmap(2) system call.

     `X' represents the major number of the library, and `Y' represents the
     minor number.  In general, a binary will be able to use a dynamic library
     with a differing minor number, but the major numbers must match.  In the
     example above, a binary linked with minor number `3' would be linkable
     against libc.so.30.1, while a binary linked with major number `31' would
     not.

     The advantages of dynamic libraries are that multiple instances of the
     same program can share address space, and the physical size of the binary
     is smaller.  The disadvantage is the added complexity that comes with
     loading the libraries dynamically, and the extra time taken to load the
     libraries.  Of course, if the libraries are not available, the binary
     will be unable to execute.  The C compiler, cc(1), can be instructed to
     link dynamically by specifying the -shared flag, although on systems that
     support it, this will be the default and need not be specified.

     Libraries with a `_p.a' suffix are profiling libraries.  They contain ex-
     tra information suitable for analysing programs, such as execution speed
     and call counts.  This in turn can be interpreted by utilities such as
     gprof(1).  The C compiler, cc(1), can be instructed to generate profiling
     code, or to link with profiling libraries, by specifying the -pg flag.

     Libraries with a `_pic.a' suffix contain position-independent code (PIC).
     Normally, compilers produce relocatable code.  Relocatable code needs to
     be modified at run-time, depending on where in memory it is to be run.
     PIC code does not need to be modified at run-time, but is less efficient
     than relocatable code.  PIC code is used by shared libraries, which can
     make them slower.  The C compiler, cc(1), can be instructed to generate
     PIC code, or to link with PIC libraries, by specifying the -fpic or -fPIC
     flags.

     With the exception of dynamic libraries, libraries are generated using
     the ar(1) utility.  The libraries contain an index to the contents of the
     library, stored within the library itself.  The index lists each symbol
     defined by a member of a library that is a relocatable object file.  This
     speeds up linking to the library, and allows routines in the library to
     call each other regardless of their placement within the library.  The
     index is created by ranlib(1) and can be viewed using nm(1).

     The building of PIC versions of libraries and dynamic libraries can be
     prevented by setting the variable NOPIC in /etc/mk.conf.  The building of
     profiling versions of libraries and/or dynamic libraries can be prevented
     by setting the variable NOPROFILE in /etc/mk.conf.  See mk.conf(5) for
     more details.

APROPOS(1)                 OpenBSD Reference Manual                 APROPOS(1)

NAME
     apropos - locate commands by keyword lookup

SYNOPSIS
     apropos [-C file] [-M path] [-m path] keyword ...

DESCRIPTION
     apropos shows which manual pages contain instances of any of the given
     keyword(s) in their title line.  Each word is considered separately and
     case of letters is ignored.  Words which are part of other words are con-
     sidered; when looking for ``compile'', apropos will also list all in-
     stances of ``compiler''.

     If the line output by apropos starts ``name (section) ...'', you can en-
     ter ``man section name'' to get its documentation.
