Open Source Desktop Operating Systems Networking Software

Pandora OPEN is a high-performance, 100% open-source monitoring ecosystem, born as the independent evolution of the Pandora FMS community branch after version 777. Licensed under GPLv2, it provides a modular and sovereign platform for supervising networks, servers, and applications without commercial dependencies. It features multi-platform agents, remote monitoring (SNMP, WMI, HTTP), GIS maps, and advanced visual dashboards. Entirely maintained by the community on GitHub, it ensures total transparency, technical flexibility, and absolute freedom for system administrators.

VTun is the easiest way to create Virtual Tunnels over TCP/IP networks with traffic shaping, compression, and encryption. It supports IP, Ethernet, PPP and other tunnel types. VTun is easily and highly configurable. VPN, Mobile IP, Shaping, etc

UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers.

VirtualBox is a powerful open-source full virtualization software that allows a user to run one or more “guest” operating systems simultaneously inside “virtual machines” on a single physical “host” machine. It supports a wide variety of host platforms (Linux, Windows, macOS, Solaris, etc.) and guest OSes, enabling, for example, running Linux on a Windows PC, running Windows Server on a Linux host, or even legacy OSes in a controlled environment. This flexibility makes VirtualBox ideal for developers, testers, sysadmins, or hobbyists who need different OS environments, want to test software across systems, or need isolation for development, sandboxing, or security experiments. VirtualBox offers both a user-friendly GUI as well as a command-line interface and headless mode, making it useful for desktop usage as well as server or automated environments.

ipmiutil is an easy to use set of IPMI server management utilities. It can get/set sensor readings & thresholds, automate SEL management, do SOL console, etc. Supports Linux, Windows, BSD, Solaris, MacOSX. The only IPMI project tool that runs natively on Windows. See ipmiutil.sf.net for rpms, etc. (formerly called panicsel). It can run driverless in Linux for use on boot media or embedded environments.

I/O performance Analysis Tool

Privoxy is a non-caching web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk. Privoxy has a flexible configuration and can be customized to suit individual needs and tastes. It has application for both stand-alone systems and multi-user networks.

Configurable tool which allows Java applications to be installed and controlled like native NT or Unix services. Includes fault correction software to automatically restart crashed or frozen JVMs. Critical when app is needed 24x7. Built for flexibility.

# OBSOLETE The project has moved to CodeBerg at https://codeberg.org/IPMITool/ipmitool IPMItool provides a simple command-line interface to IPMI-enabled devices through an IPMIv1.5 or IPMIv2.0 LAN interface or Linux/Solaris kernel driver.

Netatalk is a freely-available Open Source AFP fileserver. A *NIX/*BSD system running Netatalk is capable of serving many Macintosh clients simultaneously as an AppleShare file server (AFP).

Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

libivykis is a thin wrapper over various OS'es implementation of I/O readiness notification facilities (such as poll(2), kqueue(2)) and is mainly intended for writing portable high-performance network servers.

This project implements a simple STUN server and client on Windows, Linux, and Solaris. The STUN protocol (Simple Traversal of UDP through NATs) is described in the IETF RFC 3489, available at http://www.ietf.org/rfc/rfc3489.txt

Nagios network monitoring software is a powerful, enterprise-class host, server, application, and network monitoring tools. Designed to be fast, flexible, and rock-solid stable. Nagios runs on *NIX hosts and can monitor Windows, Linux/Unix/BSD, Netware, and network devices.

Conky is a free, light-weight system monitor for X, that displays any kind of information on your desktop. Conky is free software and runs in X on Linux and BSD. Originally a fork of Torsmo, Conky's torsmo-based code is BSD licensed. New code in Conky has been licensed under GPL 3.0. Since its inception, Conky has changed significantly from its predecessor, while maintaining simplicity and configurability. Conky can display just about anything, either on your root desktop, in its own window. Not only does Conky have many built-in objects, it can also display just about any piece of information by using scripts and other external programs. A plethora of OS stats (uname, uptime, CPU usage, mem usage, disk usage, "top" like process stats, and network monitoring, just to name a few). Conky can display information either as text, or using simple progress bars and graph widgets, with different fonts and colours.

Ping for life is a complete solution for network administrators and for people who must know the connection status through ICMP. It's the simpliest and most powerful ping graphical tool.

LCDproc controls various LCD and VFD devices in a standardized way, and ships with a client to display various system statistics. Supports multiple platforms (Linux, *BSD, Solaris). Client/server model allows multiple clients to use one display.

Siproxd is a proxy/masquerading daemon for the SIP protocol. It allows SIP clients (softphones & hardphones) to work behind an IP masquerading firewall or router.

BCU SDK is a C based, high level development system for creating programs for EIB/KNX BCU devices. It includes the GNU toolchain for the m68hc05 architecture (m68hc05-gcc, m68hc05-gdb, newlib). Bus access is possible using multiple methods.
