Open Source C Internet Software for OpenBSD

DSVPN is a Dead Simple VPN, designed to address the most common use case for using a VPN. Runs on TCP. Works pretty much everywhere, including on public WiFi where only TCP/443 is open or reliable. Uses only modern cryptography, with formally verified implementations. Small and constant memory footprint. Doesn't perform any heap memory allocations. Small (~25 KB), with an equally small and readable code base. No external dependencies. Works out of the box. No lousy documentation to read. No configuration file. No post-configuration. Run a single-line command on the server, a similar one on the client and you're done. No firewall and routing rules to manually mess with. Doesn't leak between reconnects if the network doesn't change. Blocks IPv6 on the client to prevent IPv6 leaks. Works on Linux (kernel >= 3.17), macOS and OpenBSD, as well as DragonFly BSD, FreeBSD and NetBSD in client and point-to-point modes. Adding support for other operating systems is trivial.

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Supports clusters up to 2000 nodes in size.

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.

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

Network monitoring analyzer, network scanner with ping, traceroute and beeper alert and warning mail sender. Capable of scanning IP INFINIT, automatic detection of the source of network interruptions without GUI interface configurations. More, it is designed for the computer technician who carries a powerful tool in the USB key. In addition, an audible alarm warns you via Telnet or SSH terminal, a log files recorded can be used to convey specific information to the system administrator. It is comes with a configurable for warning by email. lightweight code, coming with the source files, written in C, Email warning sender, ANDROID ping, SPARC, AMD64, traceroute, DETECT SOURCE Downs, Warning by Email, C language

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

Campagnol is a decentralized VPN over UDP tunneling. It uses UDP hole punching to open connections through NAT/firewall and OpenSSL's DTLSv1 implementation for mutual authentication and encryption.

A portable, modular and efficient ftp server, supporting SSL, IPv6, UTF-8 compliant, multithreaded, modules ,externals scripts. unix-like permissions+acls, virtual users/groups, security, speed, bandwith limitation (user,group,global), group admins, per

AstroCam is an C based daemon process for Linux and BSD to control stepmotors via SMC 800 cards. AstroCam also includes both, an PHP-based WebInterface and one based on Perl, for remote Stepengine control. You can control webcams with it.

Simple and secure TCP Proxy daemon. Refuses to run as root and confines itself to a chroot jail. Careful with signal handlers and buffers.

The IRCd Conf manager util aims at automating ircd tasks such as configuration and compilation. Other options are also included such as automatich updates. This script will eventually be ready to be used for other irc networks. Requires ncurses/dialog

Impost is a network security auditing tool designed to analyze the forensics behind protocol exploitation.

A small but powerful multiplatform/multiarch webserver daemon.

mp3source reads a playlist of MP3 files and broadcasts each one listed into an Icecast2 server, without re-encoding.

MVProc FastCGI is a Model-View-Controller platform that uses MySQL stored procedures as the Controller element. It's based on the stable Apache module MVProc, and all functionality has been tested (and load tested), so it may be "Production Ready" even though it hasn't been implemented in a production environment as yet. Benchmarking indicates it's "nearly as fast" on lighttpd as the MVProc Apache module, though a truly thorough benchmarking with a variety of servers and web applications (outputting the same result) would be more than welcome if anyone is offering... It's fast and runs great on Lighttpd! Supports application/x-www-form-urlencoded and multipart/form-data! Highly configurable! Very fast templating! Designed to be secure, with SQL injection protection, XSS attack protection, and more! Responsive project admin!

NXLog is a modular, multi-threaded, high-performance log management solution with multi-platform support. In concept it is similar to syslog-ng or rsyslog but is not limited to unix/syslog only. It can collect logs from files in various formats, receive logs from the network remotely over UDP, TCP or TLS/SSL . It supports platform specific sources such as the Windows Eventlog, Linux kernel logs, Android logs, local syslog etc. Writing and reading logs to/from databases is also supported. The collected logs can be stored into files, databases or forwarded to a remote log server using various protocols. The old BSD Syslog and the newer IETF syslog standard is fully supported by NXLog in addition to Snare, XML, JSON, GELF, KVP, CSV and custom formats. A key concept in NXLog is to be able to handle and preserve structured logs. No need to convert everything to syslog and parse these logs again at the other side. It has powerful message filtering, log rewrite and conversion capabilities.

A system for remotely testing TCP/IP services from several machines (currently HTTP, FTP, SMTP, POP3, IMAP, DNS).

OpenChange is a portable Open Source implementation of Microsoft Exchange server and Exchange protocols. It provides a complete solution to interoperate with Microsoft Outlook clients or Microsoft Exchange servers. OpenChange client-side library is used in existing messaging clients and is the solution in new projects to communicate natively with Microsoft Exchange and Exchange-compatible servers. OpenChange server is a transparent Microsoft Exchange server replacement using native Exchange protocols and does not require any plugin installation in Outlook.

OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port.

IRC Daemon based on UnrealIRCd with added features and enhancements, including features from Bahamut, UltimateIRCd, Hybrid and other IRCd software.

The latest version of QuickSock is version (1.1.2). Wrapper for the Monkey Programming Language: http://monkeycoder.co.nz/Community/posts.php?topic=4866 QuickSock is a very simple C++ based UDP networking library. QuickSock currently relies on the WinSock library on Windows, (and as of April 2013, QuickSock uses BSD sockets on other platforms). QuickSock is a work in progress, so later down the road I may add new features, or change how things function. See the "Things to add in the future" section for details. Any criticism, feature requests, and/or bug reports are appreciated. Things to add in the future: * Proper support for IPV6 networking. * Optional reliable messaging. * TCP support. * C++ native stream support. / Better error checking. * An asynchronous socket class. The source code for the project is provided 'as-is' to anyone who wants it, edit it as you like. I'd prefer it if you'd credit me for the official version, but that's completely optional
