Debian Edu LTSP-Thin-Client packages

Autofs controls the operation of the automount daemons. The automount daemons automatically mount filesystems when they are used and unmount them after a period of inactivity. This is done based on a set of pre-configured maps.

The kernel automounter implements an almost complete SunOS style automounter under Linux. A recent version of the kernel autofs4 module (builtin or separate) is required.

This is the autofs daemon.

This package provides the console with the same keyboard configuration scheme as the X Window System. As a result, there is no need to duplicate or change the keyboard files just to make simple customizations such as the use of dead keys, the key functioning as AltGr or Compose key, the key(s) to switch between Latin and non-Latin mode, etc.

The package also installs console fonts supporting many of the world's languages. It provides an unified set of font faces - the classic VGA, the simplistic Fixed, and the cleaned Terminus, TerminusBold and TerminusBoldVGA.

D-Bus 是一个消息总线，用户在应用程序间发送消息。从概念上说，在复杂性方面，它介于原始套接字和 CORBA 之间。

在使用 systemd 的系统上，该软件包默认启用会话模型，即用户的会话在其第一次登录时开始，直到该用户所有的登录会话均结束后才停止。该模型将所有并行的非图形登录会话（文本模式、ssh、cron 等）和至多一个图形会话合并进入单一的“user-session”（用户会话）或“super-session”（超级会话），其中所有后台的 D-Bus 服务均彼此共享。

该模式当前并不支持单用户的多个图形会话；因此，它特别适合 gdm，后者会在处理打开并行图形会话请求时采取切换至已有图形会话并解锁的行为。

如需恢复 dbus 传统的会话语义，即登录会话彼此之间独立的行为，请移除本软件包并转而安装 dbus-x11。

参阅 dbus 软件包描述以获取更多有关 D-Bus 的总体信息。

This package builds a bootable initramfs for Linux kernel packages. The initramfs is loaded along with the kernel and is responsible for mounting the root filesystem and starting the main init system.

和本地化(l10n)以及国际化(i18n)相关的这部分 C 程序库，所使用的机器可辨识的数 据文件、共享目标文件(shared objects)以及一些软件。

本软件包包含从源文件（软件包中已含有）生成 locale 定义文件的工具。这样您就 可以自己定制哪些 locale 定义文件是真正要生成的了。以前这个软件包的默认处理 方式是生成所有的 locale，现在的机制和以往相比要节省空间一些。以往把软件包解 压之后的大小超过了 30 兆字节。

Make an installation able to netboot as an LTSP client. For LTSP servers, also install the suggested packages (dnsmasq etc).

LTSP helps in netbooting LAN clients from a single installation that resides in a chroot or a VM on the LTSP server. This way maintaining tens or hundreds of clients is as easy as maintaining a single PC.

这是对 IETF secsh 工作组制定的安全 Shell 标准的自由、可移植的实现。 Shell标准的自由实现。

Ssh (安全 Shell，Secure Shell)是一个用于登录远程机器并在远程机器 上执行命令的程序。它在通过不安全的网络的两台不相互信任的主机之间提供了 安全加密的通信：X11 连接和任意 TCP/IP 端口均可通过安全通道转发。 它可以用于提供给程序安全的通信管道。

本软件包提供 sshd 服务器。

在某些国家，未经特别许可使用任何加密技术都可能是非法的。

sshd 取代了不安全的 rsh，它在多数用途中过时了。

p910nd is a small daemon that copies any data received on the port it is listening on to the corresponding printer port.

It is primarily intended for diskless Linux hosts running as printer drivers but there is no reason why it could not be used on diskful hosts.

Port 9100 is copied to /dev/lp0, 9101 to /dev/lp1 and 9102 to /dev/lp2. The default is port 9100 to /dev/lp0.

PulseAudio, previously known as Polypaudio, is a sound server for POSIX and WIN32 systems. It is a drop in replacement for the ESD sound server with much better latency, mixing/re-sampling quality and overall architecture.

These are some of PulseAudio's features:

• High quality software mixing of multiple audio streams with support for more than one sink/source. May be used to combine multiple sound cards into one (with sample rate adjustment).

• Wide range of supported client libraries. ESD, ALSA, oss, libao and GStreamer client applications are supported as-is. Native PulseAudio plug-ins are also available for xmms and mplayer.

• Good low latency behaviour and very accurate latency measurement for playback and recording. Ability to fully synchronize multiple playback streams.

• Network transparency, allowing an application to play back or record audio on a different machine than the one it is running on.

• Extensible plug-in architecture with plug-ins for jackd, multicast-rtp lirc and avahi, just to name a few.

This package contains the daemon and basic module set.

X2Go is a serverbased computing environment with

• session resuming
• low bandwidth support
• session brokerage support
• client-side mass storage mounting support
• client-side printing support
• audio support
• authentication by smartcard and USB stick

X2Go Client is a graphical client (Qt5) for the X2Go system. You can use it to connect to running sessions and start new sessions.

x2gothinclient-common:

Common files for X2Go TCE (display manager / mini desktop).

xinit and startx are programs which facilitate starting an X server, and loading a base X session.

xpdf is a light-weight open source viewer for Portable Document Format (PDF) files (also called 'Adobe Acrobat' or 'Acrobat' files). This is just the xpdf viewer client; various command-line pdf tools are now provided via the poppler-utils package.

Debian's xpdf is a fork of Xpdf version 3, modified to use the Poppler PDF rendering library but keeping the Motif toolkit, and nowadays maintained as the xpopple project.

The Xorg X server is an X server for several architectures and operating systems, which is derived from the XFree86 4.x series of X servers.

The Xorg server supports most modern graphics hardware from most vendors, and supersedes all XFree86 X servers.

More information about X.Org can be found at:

This package is built from the X.org xserver module.

This package depends on the full suite of input drivers for the X.Org X server (Xorg). It does not provide any drivers itself, and may be removed if you wish to only have certain drivers installed.
