Debian Edu Thin-client-server packages

Multi-threaded TFTP server implementing all options (option extension and multicast) as specified in RFC1350, RFC2090, RFC2347, RFC2348 and RFC2349. Atftpd also supports multicast protocol known as mtftp, defined in the PXE specification. The server supports being started from inetd(8) as well as in daemon mode using init scripts.

A metapackage containing dependencies for packages required on all networked workstation (thick client) installations in the Debian Edu Blend.

GStreamer is a streaming media framework, based on graphs of filters which operate on media data. Applications using this library can do anything from real-time sound processing to playing videos, and just about anything else media-related. Its plugin-based architecture means that new data types or processing capabilities can be added simply by installing new plug-ins.

This package contains the GStreamer plugin for PulseAudio, a sound server for POSIX and WIN32 systems.

iptables는 리눅스 패킷 필터링 룰셋을 설정하는데 사용하는 사용공간 명령행 프 로그램 입니다. iptables는 시스템관리자를 그 대상으로 합니다. 네트워크 주소 변환(NAT)은 패킷 필터링 룰셋에서 설정되기 때문에, iptables는 이를 위해서도 사용됩니다. iptables 패키지는 또한 ip6tables를 포함합니다. ip6tables는 IPv6 패킷 필터 설정에 사용됩니다.

This is the server from the Internet Software Consortium's implementation of DHCP.

Dynamic Host Configuration Protocol (DHCP) is a protocol like BOOTP (actually dhcpd includes much of the functionality of bootpd). It gives client machines "leases" for IP addresses and can automatically set their network configuration.

This is the DHCP server with LDAP patches applied to it.

This includes the Linux Terminal Server Project Administrator's Reference and other documentation for LTSP. It provides information about the theory of thin client networks, selecting appropriate server and thin client hardware, as well as how to configure specific LTSP features.

This is a complete LTSP server environment with all LTSP server features including a DHCP server, remote device access using ltspfs, remote sound using pulseaudio, network swap using NBD and more.

LTSP stands for 'Linux Terminal Server Project'.

LtspFS is a remote filesystem consisting of two parts: 1) A network server daemon that runs on the LTSP terminal. 2) A FUSE module that runs in userspace on the server, that connects with the daemon on the client.

This package contains the userspace parts for the LTSP server.

Nagios is a host/service/network monitoring and management system.

The purpose of this addon is to allow you to execute Nagios plugins on a remote host in as transparent a manner as possible.

This program runs as a background process on the remote host and processes command execution requests from the check_nrpe plugin on the Nagios host.

This dummy package is provided to support the transition from nagios-plugins-standard to monitoring-plugins-standard and should be removed afterwards.

Network Block Device (NBD) is a client/server protocol that emulates a block device (such as a hard disk, a floppy, or a CD-ROM) over the network, thus giving the system the ability to swap over the network, or to use raw network disk space for other purposes.

However, writing to one Network Block Device from different clients simultaneously is not recommended, and would probably result in data loss. If you want multiple clients to share a remote resource, use a network file system such as NFS or Coda.

This package provides the server binary for NBD.

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.

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.

This package contains the ESD compatibility components used by some older versions of complete desktop environments, e.g., GNOME, and many useful applications. It enables a PulseAudio sound server to fully replace ESD.

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 tools provide command line access to various features of the PulseAudio sound server. Included tools are:

  paplay - Playback a WAV file via a PulseAudio sink.
  pacat - Cat raw audio data to a PulseAudio sink.
  parec - Cat raw audio data from a PulseAudio source.
  pacmd - Connect to PulseAudio's built-in command line control interface.
  pactl - Send a control command to a PulseAudio server.
  padsp - /dev/dsp wrapper to transparently support OSS applications.
  pax11publish - Store/retrieve PulseAudio default server/sink/source
                 settings in the X11 root window.

rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks.

Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. Finally, rdiff-backup is easy to use and settings have sensible defaults.

Trivial File Transfer Protocol (TFTP) is a file transfer protocol, mainly to serve boot images over the network to other machines (PXE).

tftp-hpa is an enhanced version of the BSD TFTP client and server. It possesses a number of bugfixes and enhancements over the original.

This package contains the client.

VNC stands for Virtual Network Computing. It is, in essence, a remote display system which allows you to view a computing `desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.

This package provides a server to which X clients can connect and the server generates a display that can be viewed with a vncviewer.

The difference between the tightvncserver and the normal vncserver is the data encoding, optimized for low bandwidth connections. If the client do not support jpeg or zlib encoding it can use the default one. Later versions of vncserver (> 3.3.3r2) support a new automatic encoding that should be equally good as the tightvnc encoding.

Note: This server does not support or need a display. You need a vncviewer to see something. However, this viewer may also be on a computer running other operating systems in the local net.

xrdp offers a graphical login to a remote client using RDP (the Remote Desktop Protocol). xrdp can connect to a locally created X.org session with the xorgxrdp drivers, to a VNC X11 server, and forward to another RDP server.

xrdp accepts connections from freerdp, rdesktop, and the built-in terminal server / remote desktop clients of Microsoft Windows operating systems. In the xorgxrdp (which replaces X11RDP) and VNC modes, it provides a fully functional Linux terminal server, offering an X-Window desktop to the user. In the RDP or VNC forwarding mode, any sort of desktop can be used.

iTALC makes it possible to access and guide the activities of students from the computer of the teacher. For example, with the help of iTALC a teacher can view the contents of students' screens and see if any of them need help. If so, the teacher can access the student's desktop and provide support; the student can watch the teacher's actions and learn from them. Alternatively the teacher can switch into "demo-mode", where all the students' screens show the contents of the teacher's screen. Furthermore, actions like locking students' screens, killing games, powering clients on or off, and much more can all be performed via iTALC.

This package contains the client software for iTALC, which can be controlled using italc-master.
