Tool for debugging your C programs (malloc debugger).

Ethtool is a small utility for examining and tuning ethernet-based
network interfaces. See the man page for more details.

Expat is an XML 1.0 parser written in C. It aims to be fully
conformant. It is currently not a validating XML processor. The current
production version of expat can be downloaded from
ftp://ftp.jclark.com/pub/xml/expat.zip. The directory xmltok contains a
low-level library for tokenizing XML. The interface is documented in
xmltok/xmltok.h. The directory xmlparse contains an XML parser library
that is built on top of the xmltok library. The interface is documented
in xmlparse/xmlparse.h. The directory sample contains a simple example
program using this interface. The directory sample/build.bat is a batch
file to build the example using Visual C++. The directory xmlwf
contains the xmlwf application, which uses the xmlparse library. The
arguments to xmlwf are one or more files to check for well-formedness.
An option -d dir can be specified. For each well-formed input file, the
corresponding canonical XML is written to dir/f, where f is the
filename (without any path) of the input file. A -x option causes
references to external general entities to be processed. A -s option
makes documents that are not stand-alone cause an error (a document is
considered stand-alone if it is intrinsically stand-alone because it
has no external subset and no references to parameter entities in the
internal subset or it is declared as stand-alone in the XML
declaration).

FBSet can query and change console framebuffer settings.

Some framebuffers do not support this, such as the VESA framebuffer
"vesafb".

Fetchmail is a robust and well-documented remote mail retrieval and
forwarding utility intended to be used over on-demand TCP/IP links
(such as SLIP or PPP connections).

Fetchmail retrieves mail from remote mail servers and forwards it to
your local machine's delivery system, so it can be read by normal mail
user agents, such as mutt, elm, pine, (x)emacs/gnus, or mailx.

fetchmailconf, an interactive GUI configurator suitable for end-users,
is included in the fetchmailconf package.

Fortune displays a random text string from a set of files in a certain
format.

This occurs each time you start a login shell. To get this feature just
uncomment the respective lines in the user's .profile.

FPing is a ping-like program that 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 a list of
targets to ping. Instead of sending pings to one target until it times
out or replies, FPing sends a ping packet and moves on to the next
target in a round-robin fashion.

In the default mode, if a target replies, it is noted and removed from
the list of targets to check. If a target does not respond within a
certain time limit or retry limit, it is designated as unreachable.
FPing also supports sending a specified number of pings to a target or
looping indefinitely (as in ping).

Unlike ping, FPing is meant to be used in scripts. Its output is
designed to be easy to parse.

A portable, easy-to-use and standard compliant library suitable for
developing free and commercial software that need support for a RADIUS
protocol (RFCs 2128 and 2139).

The FreeRADIUS server has a number of features found in other servers
and additional features not found in any other server. The server's
features are:

* Support for RFC and VSA attributes

* Additional server configuration attributes

* Selection of a particular configuration

* Authentication methods

* Accounting methods

GLOBAL is a common source code tag system for C, C++, Yacc, and Java.
You can locate the specified function in source files and move there
easily. It is useful to hack a large project containing many
subdirectories or many main() functions like MH, X, or Linux kernel.

Gpart is a small tool that tries to guess what partitions are on a PC
type hard disk in case the primary partition table was damaged. Gpart
supports, among others, partitions formatted as ext2, FAT 12/16/32,
ReiserFS, NTFS, and HPFS. Read the file
/usr/share/doc/packages/gpart/README and the gpart man page before
using gpart.

GnuPG 2 is the successor of "GnuPG" or GPG. It provides: GPGSM,
gpg-agent, and a keybox library.

GnuPG Made Easy (GPGME) is a library designed to make access to GnuPG
easier for applications. It provides a high-level Crypto API for
encryption, decryption, signing, signature verification, and key
management. Currently it uses GnuPG as its back-end, but the API is not
restricted to this engine.

Because the direct use of GnuPG from an application can be a
complicated programming task, it is suggested that all software should
try to use GPGME instead. This way bug fixes or improvements can be
done at a central place and every application benefits from this.

A shell utility to access and tune the ioctl features of the Linux IDE
driver and IDE drives.

A tool for looking at the ICMP messages received on the running host.

indent can be used to make code easier to read. It can also convert
from one style of writing C code to another. indent understands a
substantial amount of C syntax, but it also tries to cope with
incomplete and malformed syntax.

IPTraf is a console-based network statistics utility. It gathers a
variety of information such as TCP connection packet and byte counts,
interface statistics and activity indicators, TCP/UDP traffic
breakdowns, and LAN station packet and byte counts.

less is a text file browser and pager similar to more. It allows
backward as well as forward movement within a file. Also, less does not
have to read the entire input file before starting. It is possible to
start an editor at any time from within less.

Lib3ds is a free alternative to Autodesk's 3DS File Toolkit for
handling 3DS files. Its main goal is to simplify the creation of 3DS
import and export filters.

Libassuan is the IPC library used by gpg2 (GnuPG version 2)

libEtPan is a mail purpose library. It will be used for low-level mail
handling : network protocols (IMAP/NNTP/POP3/SMTP over TCP/IP and
SSL/TCP/IP, already implemented), local storage (mbox/MH/maildir),
message / MIME parse

This is a library that defines common error values for all GnuPG
components. Among these are GPG, GPGSM, GPGME, GPG-Agent, libgcrypt,
pinentry, SmartCard Daemon, and possibly more in the future.

KSBA is a library to simplify the task of working with X.509
certificates, CMS data, and related data.

Libmcrypt is a data encryption library. The library is thread safe
and provides encryption and decryption functions. This version of the
library supports many encryption algorithms and encryption modes.
Supported algorithms include SERPENT, RIJNDAEL, 3DES, GOST, SAFER+,
CAST-256, RC2, XTEA, 3WAY, TWOFISH, BLOWFISH, ARC. FOUR, and WAKE.
