It should be noted that a lot of this software is portable to BSD, and should be included in the ports tree of your preferred operating system.

Communications

Web browsers

For more detailed information see Web browsers.

Firefox

Firefox is free software developed by Mozilla. It is highly extensible via addons and included as the default browser in many GNU/Linux distributions. It is often criticized on /g/ and /tech/ as "SJWfox" because of some Mozilla developers outspoken campaigns on social and political issues.

GNU IceCat

GNU IceCat is a Richard Stallman approved rebrand of Firefox maintained by the GNU Project. It removes all trademarked artwork and adds some privacy protection features.

Palemoon

Pale Moon is a fork of Firefox under a proprietary open source license. It has a familiar UI without the "Australis" redesign.

Tor Browser

Tor Browser (formerly known as Tor Browser Bundle) is a package of a modified Firefox extended support release, NoScript, HTTPS-Everywhere, Tor, TorButton and TorLauncher. It automatically routes traffic through the Tor network and deletes history and cookies when closed.

Email clients

Claws Mail

Claws Mail is an email client (and news reader), based on GTK+. The appearance and interface are designed to be familiar to new users coming from other popular email clients, as well as experienced users. Almost all commands are accessible with the keyboard.

Evolution

Evolution is a personal information management application that provides integrated mail, calendaring and address book functionality.

KMail

KMail is the email component of Kontact, the integrated personal information manager from KDE.

Thunderbird

• Alpine is a fast, easy to use email client that is suitable for both the inexperienced email user as well as for the most demanding of power users. Alpine is based on the Pine® Message System. It is released under the Apache License, Version 2.0.

• Mutt's initial interface was based largely on the ELM mail client. To a large extent, Mutt is still very ELM-like in presentation of information in menus (and in fact, ELM users will find it quite painless to switch as the default key bindings are identical). As development progressed, features found in other popular clients such as PINE and MUSH have been added, the result being a hybrid, or "mutt."

IM (Instant Messaging) clients

Pidgin

Pidgin, formerly known as GAIM, is an instant messaging client developed in C. It is based upon Libpurple and offers support for the AIM, Bonjour, Gadu-Gadu, Google Talk, Groupwise, ICQ, IRC, MSN, MXit, MySpaceIM, SILC, SIMPLE, Sametime, XMPP, Yahoo!, and Zephyr chat networks out of the box. Partial or complete support for additional networks like Xfire is offered through third-party plug-ins like Gfire. It can support OTR with a plugin. Beware it stores passwords in plain text.

RetroShare

RetroShare is an open source decentralized communication platform. It provides secure chat, photo and video sharing using OpenPGP to authenticate peers and the OpenSSL API to encrypt all communication.

Ricochet IM is and end-to-end encrypted instant messages which uses Tor hidden services.

Internet Relay Chat (IRC) clients

HexChat

HexChat is a popular replacement for the XChat IRC client, a client which offered a free binary for GNU/Linux but charges money for the Windows version. HexChat is a continuation of XChat and makes both its source code and binaries available to users of all platforms it's created for. Like its parent software, HexChat is licensed under the GNU GPL. It includes all the basic features one would need, and can be ideal both for new users and IRC veterans.

Smuxi

Smuxi is another IRC client and uses the GTK. It has some scripting capability and looks about the same on all systems. It doesn't have many features but it does those that it has well.

Terminal

• BitchX was originally a script for the IrcII client. It was converted to a program on its own right in 1996. It is highly customizable and capable of running scripts, so it can be used as an IRC bot too.

• Irssi is the father of rice clients and easily accessible for all systems. The author of the Metacity window manager for GNU/Linux describes his software as follows: "Boring window manager for the adult in you. Many window managers are like Marshmallow Froot Loops; Metacity is like Cheerios." Irssi is the terminal IRC client equivalent of that sentiment. Irssi is extensible through plugins.

• Weechat is Irssi with more rice, scripting languages, ideal defaults and development. It is rising in popularity as a preferred client on /g/. Weechat also includes plugin functionality.

VoIP (Voice-over-IP) clients

Mumble

Mumble is audio chat software. It is superior in audio quality and latency by always being the first client to use latest technologies, such as the Opus audio codec.

Skype

Skype is botnet mode in full effect. No seriously. It is also closed source and susceptible to state snooping.

TeamSpeak

TeamSpeak is widely used for gaming. Lots of permissions/ACL tuning is available. Servers must be often licensed to use without restrictions. The client has a backdoor that allows TeamSpeak Systems GmbH. to blacklist any server and take full control. It is proprietary software, and it is thus recommended to use Mumble (by virtue of performance alone, it would still be the better choice).

Tox

Tox is an open source alternative to Skype. It is in early alpha stage.

DNS

DNSCrypt

DNSCrypt adds security to the otherwise plaintext DNS lookups. Everything is encrypted, which means no more eavesdropping, and no more spoofing. Can be modified to run without systemd.

Unbound

Unbound is a validating, recursive, and caching DNS server that can enforce DNSSEC, harden your DNS queries and ultimately lower your 3rd-party exposure by caching DNS queries. Can and should be used with DNSCrypt.

File compression utilities

File compression software is widely used by various software distributors and archives to mitigate bandwidth and storage space requirements.

PeaZip

PeaZip is a free and open source archiver developed in free Pascal by Giorgio Tani. It is notable for its native PEA format and its support of cutting-edge compression technologies like PAQ and LPAQ that are not supported by other popular archivers. Like 7zip, it is capable of retrieving files from virtually any archive that one might encounter.

The PAQ and LPAQ methods are capable of an impressive degree of lossless compression, but the time and system resources required are equally impressive.

Terminal

• p7zip is a port of 7za.exe for POSIX systems. 7za.exe is the command line version of 7-zip.

• bzip2 is a high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.

• xz works in a way similar to gzip and utilizes a compression format similar to 7zip (LZMA2). In fact, .tar.xz files are compatible with 7zip.

• Packet Filter (pf) is OpenBSD's firewall which has been ported to many other operating systems.

Firewall utils

• Ufw stands for Uncomplicated Firewall, and is program for managing a netfilter firewall. It provides a command line interface and aims to be uncomplicated and easy to use.

• Arno's iptables firewall script is a highly secure front-end for iptables that extends the firewall and comes preconfigured to block all incoming connections by default. For a complete list of features, check this.

Penetration testing

• Gerix WiFi Cracker is a graphical frontend for Aircrack-ng and pyrit.

Terminal

• Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the PTW attack, thus making the attack much faster compared to other WEP cracking tools.

• Reaver implements a brute force attack against Wifi Protected Setup (WPS) registrar PINs in order to recover WPA/WPA2 passphrases. On average Reaver will recover the target AP's plain text WPA/WPA2 passphrase in four to ten hours, depending on the AP. In practice, it will generally take half this time to guess the correct WPS pin and recover the passphrase.

Password managers

KeePassX

KeePassX is a light interface and cross platform password manager published under the GNU GPL.

Terminal

• pass is a CLI password manager. It encrypts all of your passwords with GnuPG in the ~/.password_store file. One disadvantage is that it doesn't encrypt the folders it's in, meaning that if you store a password in privatewebsite.com/username, an attacker will know you have an account on privatewebsite.com - this shouldn't be an issue if your /home is encrypted and the computer is turned off. Overall it's very convienent and easy to use.

• pwsafe is another UNIX password manager that manages encrypted password databases. It is compatible with the Win32 program PasswordSafe.

Emulation and compatibility

Virtualization

VirtualBox

VirtualBox is free and open source GPL software. It was first developed by Innotek GmbH, then bought by Sun Microsystems and now continually developed by Oracle.

Compatibility layers

Windows

Wine

Wine is a compatibility layer capable of running Windows applications. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.

PlayOnLinux

PlayOnLinux is a frontend for Wine which can manage all your different Wine versions and prefixes as well as automatically resolve dependencies for your Windows applications. There's no reason to use Wine directly if you have this available.

OS X

• Darling is a translation layer that allows you to run unmodified OS X binaries on GNU/Linux platforms. In its nature, it is similar to the well-known Wine project. At this point, it is unlikely that Darling will run your favorite OS X application.
