Debian Edu Common packages

The arping utility sends ARP and/or ICMP requests to the specified host and displays the replies. The host may be specified by its hostname, its IP address, or its MAC address.

GNU bc is an interactive algebraic language with arbitrary precision which follows the POSIX 1003.2 draft standard, with several extensions including multi-character variable names, an `else' statement and full Boolean expressions. GNU bc does not require the separate GNU dc program.

The SMB/CIFS protocol provides support for cross-platform file sharing with Microsoft Windows, OS X, and other Unix systems.

This package provides utilities for managing mounts of CIFS network file systems.

This package will install a handler for command_not_found that looks up programs not currently installed but available from the repositories.

convmv can convert a single filename, a directory tree or all files on a filesystem to a different encoding. It only converts the encoding of filenames, not files contents. A special feature of convmv is that it also takes care of symlinks: the encoding of the symlink's target will be converted if the symlink itself is being converted.

It is also possible to convert directories to UTF-8 which are already partially UTF-8 encoded.

Keywords: rename, move

This package contains some small utilities for debconf developers.

Installs cfengine config files to be used by the machines set up as part of the Debian Edu (Skolelinux) network. Debian Edu is a Debian Pure Blend.

The English version of the manual for the Bookworm and Bullseye based releases of the Debian Edu / Skolelinux project is included in this package.

Debian Edu is a Debian project to make the best distribution for educational purposes. Skolelinux is the name of the Debian Pure Blend which is produced by the Debian Edu project.

The English version of the Audacity, Rosegarden and ITIL manuals are included in this package. Though outdated, still useful in parts.

Debian Edu is a Debian project to make the best distribution for educational purposes. Skolelinux is the name of the Debian Pure Blend which is produced by the Debian Edu project.

This package provides default answers for packages using debconf, and configures services to work out of the box after an installation.

This is part of the Debian Edu project.

This small tool provides an opportunity for a system administrator to perform a DHCP request to find out if a DHCP server is still running.

Dmidecode reports information about the system's hardware as described in the system BIOS according to the SMBIOS/DMI standard.

This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

Beware that DMI data have proven to be too unreliable to be blindly trusted. Dmidecode does not scan the hardware, it only reports what the BIOS told it to.

WOL (Wake-on-LAN) is a standard that allows you to turn on a computer over an Ethernet connection. Computers with WOL-enabled network interface cards can be woken from sleep mode, or powered up from standby via a BIOS feature.

One feature that separates etherwake from other implementations is that it also supports WOL passwords.

ethtool can be used to query and change settings such as speed, auto- negotiation and checksum offload on many network devices, especially Ethernet devices.

finger displays information about the system users.

fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a target host is responding. fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.

Htop is an ncursed-based process viewer similar to top, but it allows one to scroll the list vertically and horizontally to see all processes and their full command lines.

Tasks related to processes (killing, renicing) can be done without entering their PIDs.

hwinfo is the hardware detection tool used in SuSE Linux.

In Debian Edu (Skolelinux) hwinfo has shown better results than discover when detecting mouse, keyboard and monitor.

hwinfo collects information about the hardware installed on a system. Among others, libhd contains information about cdrom, zip, floppy, disks and partitions, network card, graphics card, monitor, camera, mouse, sound, pppoe, isdn, modem, printer, scanner, bios, cpu, usb, memory and smp.

This package does not include the binaries hwscan, hwscand and hwscanqueue. If you think one or more of these should be included in the package, please contact the maintainer at hwinfo@packages.debian.org.

iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question "Why is my Internet link so slow?".

iotop does for I/O usage what top(1) does for CPU usage. It watches I/O usage information output by the Linux kernel and displays a table of current I/O usage by processes on the system. It is handy for answering the question "Why is the disk churning so much?".

iotop can only run under a Linux 2.6.20 or later kernel built with the CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING and CONFIG_VM_EVENT_COUNTERS build config options on.

The iproute2 suite is a collection of utilities for networking and traffic control.

These tools communicate with the Linux kernel via the (rt)netlink interface, providing advanced features not available through the legacy net-tools commands 'ifconfig' and 'route'.

The arping command acts like the standard ping command except it pings a machine by its ARP address instead of its IP address. It is typically used to locate a machine if its hardware address is known but its IP address is unknown

This package provides "less", a file pager (that is, a memory-efficient utility for displaying text one screenful at a time). Less has many more features than the basic pager "more". As part of the GNU project, it is widely regarded as the standard pager on UNIX-derived systems.

Also provided are "lessecho", a simple utility for ensuring arguments with spaces are correctly quoted; "lesskey", a tool for modifying the standard (vi-like) keybindings; and "lesspipe", a filter for specific types of input, such as .doc or .txt.gz files.

This package contains a plugin for the Name Service Switch, providing host name resolution for the locally configured system hostname as returned by gethostname(2). It returns all locally configured public IP addresses or -- if none are configured, the IPv4 address 127.0.0.2 (which is on the local loopback) and the IPv6 address ::1 (which is the local host).

A lot of software relies on that the local host name is resolvable. This package provides an alternative to the fragile and error-prone manual editing of /etc/hosts.

Installing this package automatically adds myhostname to /etc/nsswitch.conf.

Many programs use $TMPDIR for storing temporary files. Not all of them are good at securing the permissions of those files. libpam-tmpdir sets $TMPDIR and $TMP for PAM sessions and sets the permissions quite tight. This helps system security by having an extra layer of security, making such symlink attacks and other /tmp based attacks harder or impossible

libwww-perl (also known as LWP) is a collection of Perl modules that provide a simple and consistent programming interface (API) to the World-Wide Web. The main focus of the library is to provide classes and functions that allow you to write WWW clients. It also contains general purpose modules, as well as a simple HTTP/1.1-compatible server implementation.

A small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 systems, on some PowerPC machines (PowerMac G4 is known to work) and AMD64.

Information can be output in plain text, HTML or XML.

Uses information in sysfs (Linux kernels 2.6.0 and later) to list all scsi devices (or hosts) currently attached to the system. Options can be used to control the amount and form of information provided for each device.

GNU Midnight Commander is a text-mode full-screen file manager. It uses a two panel interface and a subshell for command execution. It includes an internal editor with syntax highlighting and an internal viewer with support for binary files. Also included is Virtual Filesystem (VFS), that allows files on remote systems (e.g. FTP, SSH servers) and files inside archives to be manipulated like real files.

Memtest86+ provides a more thorough memory check than that provided by BIOS memory tests. Can be loaded and run either directly by a PC BIOS (legacy or UEFI) or via an intermediate bootloader.

This tester runs independently of any OS - it is run at computer boot-up, so that it can test all of your memory. You may want to look at `memtester', which allows one to test your memory within Linux, but this one won't be able to test your whole RAM.

It can output a list of bad RAM regions usable by the BadRAM kernel patch, so that you can still use your old RAM with one or two bad bits.

Mtools is a collection of utilities to access MS-DOS disks from Unix without mounting them. It supports Win'95 style long file names, OS/2 Xdf disks, ZIP/JAZ disks and 2m disks (store up to 1992kB on a high density 3 1/2 disk).

Also included in this package are commands to eject and manipulate the write/password protection control of Zip disks.

mtr combines the functionality of the 'traceroute' and 'ping' programs in a single network diagnostic tool.

As mtr starts, it investigates the network connection between the host mtr runs on and a user-specified destination host. After it determines the address of each network hop between the machines, it sends a sequence of ICMP ECHO requests to each one to determine the quality of the link to each machine. As it does this, it prints running statistics about each machine.

mtr-tiny is compiled without support for X and conserves disk space.

Ncftp allows a user to transfer files to and from a remote network site, and offers additional features that are not found in the standard interface, ftp. This version has Readline support enabled.

Nmap is a utility for network exploration or security auditing. It supports ping scanning (determine which hosts are up), many port scanning techniques, version detection (determine service protocols and application versions listening behind ports), and TCP/IP fingerprinting (remote host OS or device identification). Nmap also offers flexible target and port specification, decoy/stealth scanning, sunRPC scanning, and more. Most Unix and Windows platforms are supported in both GUI and commandline modes. Several popular handheld devices are also supported, including the Sharp Zaurus and the iPAQ.

nullidentd is a small, fast and secure identd daemon. It returns a static string for every query.

The inetd server is a network daemon program that specializes in managing incoming network connections. Its configuration file tells it what program needs to be run when an incoming connection is received. Any service port may be configured for either of the tcp or udp protocols.

This is a port of the OpenBSD daemon with some debian-specific features. This package supports IPv6, built-in libwrap access control, binding to specific addresses, UNIX domain sockets and socket buffers tuning.

This package contains various utilities for inspecting and setting of devices connected to the PCI bus.

plocate is a locate(1) based on posting lists, giving much faster searches on a much smaller index. It is a drop-in replacement for mlocate in nearly all aspects, and is fast on SSDs and non-SSDs alike.

This package provides three small programs that gather system information from diverse files under /proc and /sys and print it to the screen:

• lsdev - information from /proc about installed hardware;
• procinfo - system monitoring statistics from /proc and /sys;
• socklist - a summary of open network sockets from /proc/net.

Can be used to create mail-servers, mailing lists, sort your incoming mail into separate folders/files (very convenient when subscribing to one or more mailing lists or for prioritising your mail), preprocess your mail, start any programs upon mail arrival (e.g. to generate different chimes on your workstation for different types of mail) or selectively forward certain incoming mail automatically to someone.

This package contains miscellaneous utilities that use the proc FS:

• fuser: identifies processes that are using files or sockets.
• killall: kills processes by name (e.g. "killall -HUP named").
• peekfd: shows the data traveling over a file descriptor.
• pstree: shows currently running processes as a tree.
• prtstat: print the contents of /proc//stat

Resolvconf is a framework for keeping up to date the system's information about name servers. It sets itself up as the intermediary between programs that supply this information (such as ifup and ifdown, DHCP clients, the PPP daemon and local name servers) and programs that use this information (such as DNS caches and resolver libraries).

This package may require some manual configuration. Please read the README file for detailed instructions.

rsync is a fast and versatile file-copying tool which can copy locally and to/from a remote host. It offers many options to control its behavior, and its remote-update protocol can minimize network traffic to make transferring updates between machines fast and efficient.

It is widely used for backups and mirroring and as an improved copy command for everyday use.

This package provides both the rsync command line tool and optional daemon functionality.

Rsyslog is a multi-threaded implementation of syslogd (a system utility providing support for message logging), with features that include:

• reliable syslog over TCP, SSL/TLS and RELP
• on-demand disk buffering
• email alerting
• writing to MySQL or PostgreSQL databases (via separate output plugins)
• permitted sender lists
• filtering on any part of the syslog message
• on-the-wire message compression
• fine-grained output format control
• failover to backup destinations
• enterprise-class encrypted syslog relaying

It is the default syslogd on Debian systems.

GNU Screen is a terminal multiplexer that runs several separate "screens" on a single physical character-based terminal. Each virtual terminal emulates a DEC VT100 plus several ANSI X3.64 and ISO 2022 functions. Screen sessions can be detached and resumed later on a different terminal.

Screen also supports a whole slew of other features, including configurable input and output translation, serial port support, configurable logging, and multi-user support.

The smartmontools package contains two utility programs (smartctl and smartd) to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (S.M.A.R.T.) built into most modern ATA and SCSI hard disks. It is derived from the smartsuite package, and includes support for ATA/ATAPI-5 disks. It should run on any modern Linux system.

strace is a system call tracer, i.e. a debugging tool which prints out a trace of all the system calls made by another process/program. The program to be traced need not be recompiled for this, so you can use it on binaries for which you don't have source.

System calls and signals are events that happen at the user/kernel interface. A close examination of this boundary is very useful for bug isolation, sanity checking and attempting to capture race conditions.

The sysfs is a virtual file system found in Linux kernels 2.5+ that provides a tree of system devices. This package provides the program 'systool' to query it, which can be used to list devices by bus, class, and topology.

In addition this package ships a configuration file /etc/sysfs.conf which allows one to conveniently set sysfs attributes at system bootup (via an init script).

This program allows you to dump the traffic on a network. tcpdump is able to examine IPv4, ICMPv4, IPv6, ICMPv6, UDP, TCP, SNMP, AFS BGP, RIP, PIM, DVMRP, IGMP, SMB, OSPF, NFS and many other packet types.

It can be used to print out the headers of packets on a network interface, filter packets that match a certain expression. You can use this tool to track down network problems, to detect attacks or to monitor network activities.

The more traditional traceroute(8) sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination.

The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that traceroute(8) sends out end up being filtered, making it impossible to completely trace the path to the destination. However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters.

Vim is an almost compatible version of the UNIX editor Vi.

Many new features have been added: multi level undo, syntax highlighting, command line history, on-line help, filename completion, block operations, folding, Unicode support, etc.

This package contains a version of vim compiled with a rather standard set of features. This package does not provide a GUI version of Vim. See the other vim-* packages if you need more (or less).

Apticron is a simple script which sends daily emails about pending package updates such as security updates, properly handling packages on hold both by dselect and aptitude.

cpqarrayd is a userspace monitoring daemon for HP (Compaq) SmartArray hardware RAID controllers. These controllers usually come built-in to ProLiant, or as a PCI card for ProLiant or Integrity systems. This daemon reports status changes in the disk array to syslog and, optionally, to a snmp trap host.

The default is to only log to the syslog. You can specify traphosts with the -t parameter at the commandline. Multiple traphosts are allowed.

This tool works with the SmartArray drivers found in Linux kernels (cciss and ida drivers).

Contains a tool that is run by a cron job at regular intervals. By default it just updates the package list and downloads new packages without installing. You can instruct it to run anything that you can do with apt-get (or aptitude).

It can optionally send mail to the system administrator on errors, log to syslog or a separate log file.

Observe that this tool may be a security risk, so you should not set it to do more than necessary. Automatic upgrade of all packages is NOT recommended unless you are in full control of the package repository.

These programs are designed to integrate with standard shell tools, extending them to operate on the Debian packaging system.

Package name in brackets denote (non-essential) dependencies of the scripts. Packages names with an asterisk ("*") denote optional dependencies, all other are hard dependencies.

Hard dependencies of single tools are listed in the Recommends field of the package and optional dependencies of single tools in the Suggests field -- as common with many "collection" style Debian packages.

debsecan is a tool to generate a list of vulnerabilities which affect a particular Debian installation. debsecan runs on the host which is to be checked, and downloads vulnerability information over the Internet. It can send mail to interested parties when new vulnerabilities are discovered or when security updates become available.

Suite of programs to manage some I2O-compliant RAID controllers; in particular some Adaptec hardware; to be very specific those using the dpt_i2o kernel module or CONFIG_SCSI_DPT_I2O driver, or (for more recent kernels) the i2o_block and i2o_config modules, or CONFIG_I2O_BLOCK and CONFIG_I2O_CONFIG drivers. One can create/delete a RAID array, add/remove a hot spare drive to/from an array, activate/silence the alarm, and query array/disk status.

GNU Emacs is the extensible self-documenting text editor. This is a metapackage that will always depend on the latest recommended Emacs variant (currently emacs-gtk).

GDB is a source-level debugger, capable of breaking programs at any specific line, displaying variable values, and determining where errors occurred. Currently, gdb supports C, C++, D, Objective-C, Fortran, Java, OpenCL C, Pascal, assembly, Modula-2, Go, and Ada. A must-have for any serious programmer.
