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The iptables/xtables framework has been replaced by nftables.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.

This package includes the important tools for controlling the network subsystem of the Linux kernel. This includes arp, ifconfig, netstat, rarp, nameif and route. Additionally, this package contains utilities relating to particular network hardware types (plipconfig, slattach, mii-tool) and advanced aspects of IP configuration (iptunnel, ipmaddr).

In the upstream package 'hostname' and friends are included. Those are not installed by this package, since there is a special "hostname*.deb".

NFS-kärnservern är för närvarande den rekommenderade NFS-servern för Linuxanvändning, med funktioner såsom NFSv3 och NFSv4, Kerberos-stöd via GSS och mycket mer. Den är också avsevärt snabbare och vanligen mer pålitlig än NFS-servrar i användarrymden (från unfs3- och nfs-user-server-paketen). Den är dock svårare att felsöka än servrarna i användarrymden, och har något annorlunda funktioner.

Detta paket innehåller det användarrymdsstöd som behövs för att använda NFS-kärnservern. De flesta administratörer som vill sätta upp en NFS-server vill installera detta paket.

rdiff-backup säkerhetskopierar en katalog till en annan, möjligen över ett nätverk. Målkatalogen blir en kopia av källkatalogen, men extra omvända skillnader lagras i en speciell underkatalog av målkatalogen så att du fortfarande kan återställa filer som förlorades för ett tag sedan. Idén är att kombinera de bästa egenskaperna hos spegling och inkrementell säkerhetskopiering. rdiff-backup bevarar också underkataloger, hårda länkar, dev-filer, rättigheter, uid/gid-ägande, modifieringstider, utökade attribut, acl:er och resursgreningar.

rdiff-backup kan också köras genom rör på ett bandbreddseffektivt sätt, liknande rsync. Således kan du använda rdiff-backup och ssh för att säkert säkerhetskopiera en hårddisk till en fjärrplats, och endast skillnaderna kommer att överföras. Slutligen är rdiff-backup lättanvänt och inställningarna har vettiga standardvärden.

Squashfs is a highly compressed read-only filesystem for Linux. It uses zlib compression to compress both files, inodes and directories. Inodes in the system are very small and all blocks are packed to minimise data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.

Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed.

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 server.

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.
