Debian Edu LTSP-Server packages

debootstrap is used to create a Debian base system from scratch, without requiring the availability of dpkg or apt. It does this by downloading .deb files from a mirror site, and carefully unpacking them into a directory which can eventually be chrooted into.

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

The iptables/xtables framework has been replaced by nftables. You should consider migrating now.

iptables is the userspace command line program used to configure the Linux packet filtering and NAT ruleset. It is targeted towards systems and networks administrators.

This package contains several different utilities, the most important ones:

iptables-nft, iptables-nft-save, iptables-nft-restore (nft-based version)

iptables-legacy, iptables-legacy-save, iptables-legacy-restore (legacy version)

ip6tables-nft, ip6tables-nft-save, ip6tables-nft-restore (nft-based version)

ip6tables-legacy, ip6tables-legacy-save, ip6tables-legacy-restore (legacy version)

arptables-nft, arptables-nft-save, arptables-nft-restore (nft-based version)

ebtables-nft, ebtables-nft-save, ebtables-nft-restore (nft-based version)

iPXE is network boot firmware. It supports a variety of network cards, including some wireless cards, and variety of network protocols (traditional DHCP, BOOTP and TFTP and also HTTP, iSCSI, SAN via FCoE and Infiniband). It supports scripting.

It is possible to use iPXE as a PXE ROM in the network card or to chainload it from other boot methods.

This package provides boot code for all supported network cards in one binary and several bootable formats.

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.

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.

Plugins for nagios compatible monitoring systems like Naemon and Icinga. It contains the following plugins:

 check_breeze, check_dbi, check_dig, check_disk_smb, check_dns,
 check_flexlm, check_fping, check_game, check_hpjd, check_ifoperstatus,
 check_ifstatus, check_ldap, check_ldaps, check_mailq, check_mysql,
 check_mysql_query, check_oracle, check_pgsql, check_radius, check_rpc,
 check_snmp, check_wave

This package provides the suite of plugins that are most likely to be useful on a central monitoring host. Some scripts need more packages installed to work, which is implemented as recommends.

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.

이 패키지는 리눅스 커널의 네트워크 서브시스템 제어를 위한 중요한 도구가 들 어 있습니다. 이 패키지는 arp, ifconfig, netstat, rarp, nameif 그리고 route 등이 들어 있습니다. 게다가, 이 패키지는 특정 네트워크 하드웨어 타입 (plipconfig, slattach, mii-tool)이나 IP 설정의 진보된 형태(iptunnel, ipmaddr)와 관련된 도구가 들어 있습니다.

원 패키지에는 'hostname' 및 관련 프로그램이 들어 있습니다. "hosname*.deb" 패키지가 따로 있기 때문에, 이 패키지에서는 hostname 및 관련 프로그램은 설치 하지 않습니다.

The NFS kernel server is currently the recommended NFS server for use with Linux, featuring features such as NFSv3 and NFSv4, Kerberos support via GSS, and much more. It is also significantly faster and usually more reliable than the user-space NFS servers (from the unfs3 and nfs-user-server packages). However, it is more difficult to debug than the user-space servers, and has a slightly different feature set.

This package contains the user-space support needed to use the NFS kernel server. Most administrators wishing to set up an NFS server would want to install this package.

rdiff-backup은 네트워크를 통해서 디렉토리를 다른 곳으로 백업합니다. 목적 디 렉토리는 소스 디렉토리의 복사본이지만, 여분의 역방항 diffs가 목적 디렉토리 의 특정 서브 디렉토리에 저장되기 때문에 얼마전에 손실된 파일을 복구할 수 있 습니다. 이 아이디어는 미러와 증분 백업의 최고 기능을 결합한 것 입니다. rdiff-backup은 서브디렉토리, 하드 링크, dev 파일, 퍼미션, uid/gid 소유권, 수정 시간, 확장된 속성, acl, 리소스 포크를 보존합니다.

또한 rdiff-backup은 rsync 처럼 pipe를 통해 대역폭을 효과적인 방법으로 사용 할 수 있습니다. 따라서, rdiff-bacup 및 ssh를 사용해서 외부 위치에 하드 드라 이브를 안전하게 백업할 수 있으며 오직 차이점이 전송됩니다. 마지막으로 rdiff-backup은 사용하기 쉽고 설정에 적절한 기본값을 가지고 있습니다.

Squashfs는 리눅스를 위한 고도로 압축된 읽기 전용 파일 시스템입니다. 파일, 아이노드, 디렉토리 모두를 압축하기 위해 zlib 압축을 사용합니다. 시스템에서 아이노드는 매우 작고 모든 블록은 데이타 오버헤드를 최소화하기 위해 pack 됩니다. 4K 보다 큰 블록 사이즈는 최대 64K까지 지원됩니다.

Squashfs는 보관용 (예, .tar.gz 파일을 사용할 수 있는 경우) 그리고 낮은 오버헤드가 필요한 제한된 블록 장치/메모리 시스템 (예, 임베이드 시스템)을 위한 일반적인 읽기 전용 파일시스템으로 사용됩니다.

Trivial File Transfer Protocol (TFTP)는 주로 네트워크를 통해 부팅 이미지를 다른 시스템 (PXE)에 제공하는 파일 전송 프로토콜입니다.

tftp-hpa는 BSD TFTP 클라이언트 서버의 발전된 버전입니다. 원본에 비해 여러가지 버그 수정 및 향상된 기능을 포함합니다.

이 패키지는 서버를 포함합니다.

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.

X2Go is a server based 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

This package contains the main daemon and tools for X2Go server-side session administrations.

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.
