PAM库的aspect，甚至是关于正在修改的那些非PAM应用程序的提示消息，
而这些应用支持新的已鉴定的模块。
<p>PAM升级的主要部分是将 <package/secure-su/合并到主注册包。
<package/shellutils/提供的缺省的 <prgn/su/现在由 <package/login/
提供，所以PAM组合更完善更system wide。如果你习惯于使用缺省的
<prgn/su/，那么你不必注意新版本中的任何改动。但是，旧的
<package/secure-su/包的使用者必须检查他们的配置以确信新的
PAM安装是否兼容。
<p>你可能注意到这个发行版本包含两个Perl版本：5.004（在
<package/perl-5.004*/包）和5.005（在 <package/perl-5.005*/包）。
我们强烈推荐使用后者，那个新版本，并删除旧版本，它不过是一个方便
程序员的兼容版本。<footnote>这个操作通过安装perl-5.005包来完成，
使用诸如<tt/apt-get install perl-5.005/命令。</footnote>
如果在你的脚本中有/使用任何新包<package/lib*-perl/中的Perl模块，
你将必须文件 <file>/usr/bin/perl</file>进行符号连接
（用<prgn/update-alternatives/），指向Perl 5.005，否则你将遇到麻烦。
<p>请注意Debian non-US 存档已经作了轻微的改动来支持自由软件和
非自由软件的区分。如果你已经使用 <package/apt/来访问non-US，
你需要改变你的文件 <file>/etc/apt/sources.list</file>中的下列行:
<example>
deb http://non-US.debian.org/debian-non-US potato/non-US main contrib non-free
</example>
<p> <prgn/inetd/ 的以前版本(由 <package/netbase/包提供) 有一个bug，
当 <prgn/inetd/ 被终止时，以有的到某些互联网服务器的连接能够通过重起终止
~~~~~~~~~ ~~~~~~~~~~~~~~~~~~
<prgn/inetd/。这个bug已经在当前版本 <package/netbase/中修正，但是
旧版本仍然容易受到攻击。如果你发现 <prgn/inetd/ 不能正常重启动，寻找任何
仍在运行的<prgn/inetd/ 程序，或者执行诸如 "-discard" 或 "-echo"操作的程序。
如果你安装了 <package/psmisc/ 包，运行:
<example>
sed 's/[[:space:]][[:space:]]*/ /g' /etc/inetd.conf |
grep '^ *[^#]' | cut -d" " -f1,3 |
while read serv type; do
fuser -n $type $serv;
done
</example>
在root用户权限下，它将告诉你哪一个程序正在使用 <prgn/inetd/关注的端口。
<p>smail MTA的用户要注意发行版本&release；不要再 ship那个包，因为它
~~~~~
在我们测试时有严重错误。修正的smail包仍放在 unstable目录中，或在
<url id="http://www.fs.tum.de/~bunk/smail.html";>.<!-- um,
there's nothing there -->
<p>新的 XFree86 和其它 <package/xserver-*/ 包也由这个发行版引入，
与以前的版本，2.1版，比较，它们提供了对你的图形硬件的更好支持，
尤其是针对许多新图形卡的驱动，例如 3D加速卡。如果你不能正确地
选择X服务器包，可以尝试 <prgn/xviddetect/程序(来自 <package/xviddetect/包)，
它将输出你需要的基于你的PCI/AGP总线信息的 X 服务器的名字。
<![ %sparc [
<p>如果你没有安装gpm但希望在你的SPARC系统上运行 X，
你不得不先删除 <file>/dev/gpmdata</file> 文件。
]]>
<p>使用Intel i810芯片组的用户应该知道，要正确地执行功能，X 服务器需要未
装入Linux内核源码的Linux内核模块支持。这个模块的源码以及编译和使用的
说明书能在主页<url id="&url-x-strike-force" name="X Strike Force">中找到。
<p>如果你使用的X服务器正在升级<prgn/xfs/字体服务器的主机，它将在
<prgn/xfs/停止时失去同字体服务器的连接。这不是致命的，但却令人讨厌。
注意：相似的问题会出现在其它daemons上，所以你要做好准备。

aspect of the PAM library, even tips on modifying your existing non-PAM
apps to support the new authentication model.
<p>One major part of the PAM upgrade was merging <package/secure-su/
into the main login package. The default <prgn/su/ provided by
<package/shellutils/ is now provided by the <package/login/ package so
that PAM integration was more complete and system wide. If you used to
use the default <prgn/su/, then you should not notice any changes with
the new version. However, users of the obsolete <package/secure-su/
package may have to check their configurations to ensure that the new PAM
setup is compatible.
<p>You may notice that this release includes two versions of Perl: 5.004
(in <package/perl-5.004*/ packages) and 5.005 (in <package/perl-5.005*/
packages). We highly recommend using the latter, newer version, and
removing the old version, which is kept only for compatibility, as a
convenience to programmers.<footnote>This can be accomplished by
installing the perl-5.005 package, using e.g.
<tt/apt-get install perl-5.005/</footnote>
If you have/use any Perl modules from the new <package/lib*-perl/ packages
in your scripts, you will have to set the <file>/usr/bin/perl</file>
symlink (using <prgn/update-alternatives/) to point to Perl 5.005,
otherwise you will experience problems.
<p>Please note that the Debian non-US archive has been slightly reorganized
in order to support separation between free and non-free software.
If you already used <package/apt/ to access it, you will need to change
your <file>/etc/apt/sources.list</file> lines for non-US to this form:
<example>
deb http://non-US.debian.org/debian-non-US potato/non-US main contrib non-free
</example>
<p>Previous versions of <prgn/inetd/ (provided by the <package/netbase/
package) had a bug in that when <prgn/inetd/ was stopped, an existing
connection to some of the internal services could stop <prgn/inetd/ from
restarting. This bug has been fixed in the current <package/netbase/, but
older version of it are still vulnerable. If you find <prgn/inetd/ isn't
restarting properly, look for any existing <prgn/inetd/ processes that are
still running, or processes such as "-discard" or "-echo". If you have the
<package/psmisc/ package installed, running:
<example>
sed 's/[[:space:]][[:space:]]*/ /g' /etc/inetd.conf |
grep '^ *[^#]' | cut -d" " -f1,3 |
while read serv type; do
fuser -n $type $serv;
done
</example>
as root will tell you which processes are using ports <prgn/inetd/ is
interested in.
<p>Users of smail MTA will notice that release &release; doesn't ship
that package anymore, due to serious bugs it had during our test cycles.
Updated smail packages may still be found in the unstable distribution,
or at <url id="http://www.fs.tum.de/~bunk/smail.html";>.<!-- um,
there's nothing there -->
<p>The new XFree86 and other <package/xserver-*/ packages introduced in
this release, compared to those in the previous release, 2.1, may very
well contain better support for your graphics hardware, especially drivers
for newer graphics cards such as many 3D accelerator cards. If you don't
know exactly which X server package to choose, try the <prgn/xviddetect/
program (from <package/xviddetect/ package), that will output the name of
the needed X server, based on information found about your PCI/AGP bus.
<![ %sparc [
<p>If you don't have gpm installed and wish to run X on your SPARC system,
you may have to remove the <file>/dev/gpmdata</file> file first.
]]>
<p>Users of the Intel i810 chipset should be aware that, to properly
function, the X server requires a Linux kernel module that does not ship
with the Linux kernel sources. The source code to this module, and
instructions for compiling it and using it, may be found at the
<url id="&url-x-strike-force" name="X Strike Force"> page.
<p>If the X server you are using refers to the upgrading host for
<prgn/xfs/ font services, it will lose its connection to the font server
when <prgn/xfs/ is stopped. This is not fatal, but can be annoying.
Note: similar things may happen for other daemons, so be prepared.
