InputPlumber is an open source input routing and control daemon for Linux. It can be used to combine any number of input devices (like gamepads, mice, and keyboards) and translate their input to a variety of virtual device formats.
Tinyproxy is a small, efficient HTTP/SSL proxy daemon released under the GNU General Public License. Tinyproxy is very useful in a small network setting, where a larger proxy would either be too resource intensive, or a security risk. One of the key features of Tinyproxy is the buffering connection concept. In effect, Tinyproxy will buffer a high speed response from a server, and then relay it to a client at the highest speed the client will accept. This feature greatly reduces the problems with
tinc is a Virtual Private Network (VPN) daemon that uses tunneling and encryption to create a secure private network between multiple hosts on the Internet. This tunneling allows VPN sites to share information with each other over the Internet without exposing any information.
This project aims to make updating firmware on Linux automatic, safe, and reliable.
Sndio is a small audio and MIDI framework part of the OpenBSD project and ported to FreeBSD, Linux and NetBSD. It provides a lightweight audio & MIDI server and a fully documented user-space API to access either the server or the hardware directly in a uniform way. Sndio is designed to work for desktop applications, but pays special attention to synchronization mechanisms and reliability required by music applications. Reliability through simplicity are part of the project goals.
mrouted is an implementation of the IPv4 multicast routing protocol DVMRP, RFC 1075. It is capable of turning a UNIX workstation, or Linux device, into a multicast router with tunneling support. Support for IGMPv1, IGMPv2, and IGMPv3. Comes with mroutectl for interacting with the daemon.
PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It aims to support the usecases currently handled by both PulseAudio and Jack and at the same time provide same level of powerful handling of Video input and output. It also introduces a security model that makes interacting with audio and video devices from containerized applications easy, with supporting Flatpak applications being the primary goal. Alongside Wayland and Flatpak we expect PipeWire to pro
NetworkManager attempts to keep an active network connection available at all times. The point of NetworkManager is to make networking configuration and setup as painless and automatic as possible. NetworkManager is intended to replace default route, replace other routes, set IP addresses, and in general configure networking as NM sees fit (with the possibility of manual override as necessary). In effect, the goal of NetworkManager is to make networking Just Work with a minimum of user hassle
SMCRoute is a daemon and command line tool to manipulate the multicast routing table in the UNIX kernel. Both FreeBSD and Linux kernels are supported. SMCRoute can be used as an alternative to dynamic multicast routing daemons like mrouted or pimd in situations where (only) static multicast routes should be maintained and/or no proper IGMP/MLD signaling exists.
Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH. We call it clientless because no plugins or client software are required. Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.
Cyberprobe is a network attack monitoring software stack. It collects data packets for inspection, logging and analysis. It can be integrated with snort to record the actual intrusion source. While Cybermon is highly configurable protocol decoder and analysis tool, which can also automate responses such as dynamic connection resets, firewalling or forged DNS replies.
Inadyn is a small and simple DDNS client with HTTPS support, both GnuTLS and OpenSSL are supported. Inadyn is commonly available in many GNU/Linux distributions, used in off-the-shelf routers and Internet gateways to automate the task of keeping your DNS record up to date with any IP address changes from your ISP. It can also be used in installations with redundant (backup) connections to the Internet.
This is a TCP port redirector for UNIX. It can be run under inetd or as standalone (in which case it handles multiple connections). It is 8 bit clean, not limited to line mode, is small and lightweight. If you want access control, run it under xinetd, or inetd with TCP wrappers. Redir listens for TCP connections on a given port, and, when it receives a connection, then connects to a given destination address:port, and pass data between them. It finds most of its applications in traversing firew
Valvula is a high performance mail policy daemon for Postfix. It provides out of the box support for sender login mismatch, mail quotas, per user and per domain blacklists and whitelists, and much more. It is system administrator friendly, providing many automatic features like automatically detecting Postfix MySQL databases to determine local domains and local accounts. It is fully extensible through plugins.
fIcy is a small icecast/shoutcast stream grabber suite for use under shell environment. Its goal is to automatically rip a stream into user customisable files. It will work with ICY compatible streams, allowing you to either to save the stream to disk or to pipe the output to a media player, or even both. fIcy, among other uses, is ideal for batch/unattended recording of radio programs and stream debugging.
downtimed is a program that monitors operating system downtime, uptime, shutdowns, and crashes and records such events. At OS startup it logs information about previous downtime. It then periodically updates a time stamp file on the disk, which is used to determine the approximate time when the system was last up and running. During a graceful system shutdown, it records a time stamp in another file. The downtimes(1) command line tool can be used to inspect records of past downtime.
bftpd is an FTP server for Unix systems, which is designed to be portable and fast. It supports inetd and standalone mode, most RFC FTP commands and is very easy to configure.
Play the popular card game Mau Mau (similar to UNO®) against the computer or over the network with your friends. It consists of a highly configurable stand-alone server and a client based on Qt4/5. The client's development is now ceased and in search of a new maintainer, transforming it from a worse and annoying showstopper to a usable and fun to play one. Features: * Play against an unlimited number of tactical playing computer opponents * Play against an unlimited number of human players ov
An empty, event-driven daemon with built-in CLI. Includes a simple publish/subscribe mechanism. Written in C and has no dependencies (but plug-ins can be in any language). Intended for robotics but may be useful elsewhere.
AppFS is a FUSE-based filesystem that presents a filesystem view of remote packages presented via HTTP for the purpose of running software without the hassle of installing it. Instead, as files are requested they are downloaded and made available.
Rsyslog is a log proccessing framework optimized for performance and throughput. It has a modular design, and offers great security features. It evolved from a regular syslogd into a log message distribution and transformation system for different targets. It's multi-threaded, works atop TCP, SSL, TLS, RELP, can use MySQL, PostgreSQL, Oracle and other databases, filter syslog messages even partially, provides a configurable output format, and has been tested with enterprise-class relay chains.
Rudiments is a C++ class library. It provides base functionality for things such as daemons, client and server implementations. It also wraps standard C functions for regexps, semaphores, signal handling, socket communication, string processing, command line and environment interfaces, crypt, device handling, file and directory processing, serial and modem ports, threading, and XML processing.
SQL Relay provides a database proxy connection pool, load balancing, query routing and filtering. It eases replication and scalability. It supports MySQL, PostgreSQL, SQlite, ODBC, Oracle, Sybase, DB2, Firebird, MS SQL Server and MS Access. There are drop-in MySQL and PostgreSQL libraries to use it without client adaption. A native SQL Relay client API is also available for C, C++, C#, PHP, Perl, Python, Ruby, Java, TCL and Erlang, or drivers for Perls DBI, Pythons DB, Rubys DBI or PHPs PDO and
Hotspotd is a daemon to create a WiFi hotspot on Linux. It uses the standard hostapd program for access-point provisioning and establishes a NAT (Network address translation) with the target device using the iptables firewall. Hotspotd uses dnsmasq to allocate ip-addresses in a pre-defined range for target devices.
