Open Source BSD Proxy Servers

The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform-independent SMTP Proxy server which implements auto-whitelists, self learning Hidden-Markov-Model and/or Bayesian, Greylisting, DNSBL, DNSWL, URIBL, SPF, SRS, Backscatter, Virus scanning, attachment blocking, Senderbase and multiple other filter methods. Click 'Files' to download the professional version 2.8.1 build 24261. A linux(ubuntu 20.04 LTS) and a freeBSD 12.2 based ready to run OVA of ASSP V2 are also available for download. NOTICE: V1 development has been stopped at the end of 2014 (1.10.1 build 16060). Possibly there will be done some bugfixing in future. Please upgrade to V2, which is and will be actively maintained.

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.

c-icap is an implementation of an ICAP server. It can be used with HTTP proxies that support the ICAP protocol such as the Squid 3.x HTTP proxy server to implement content adaptation/filtering services.

This program allows you to use SSH, TELNET, VNC, FTP and any other Internet application from behind HTTP(HTTPS) and SOCKS(4/5) proxy servers. This "proxifier" provides proxy server support to any app.

Caddy is a powerful, extensible, enterprise-ready server platform that uses TLS by default. Everything you would require in your infrastructure, from TLS certificate renewals and OCSP stapling, to reverse proxying and ingress, Caddy simplifies it all. Its modular architecture lets you do more with just a single static binary that compiles for any platform. Caddy is the only web server that uses HTTPS automatically and by default. It automatically renews TLS certificates, staples OCSP responses and more. Though used mostly as an HTTPS server, Caddy can be used to run Go applications, offering automated documentation, graceful on-line config changes via API and more to these apps. Caddy is very extensible, with a powerful plugin system unlike any other web server.

Screen squid is web-based interface for viewing reports based on Squid proxy server log files. It can be accessed from web-browser through more than 50 reports. No extra files, only DB. All reports generated "on-the-fly". And we got personal cabinet for each user/group.

mpg321 is a completely Free drop-in replacement for mpg123. It has been designed to work as a drop-in replacement for mpg123, for the use of front ends, shell scripts, etc. It does all mp3 decoding using the high-quality integer-only MAD library.

ModSecurity is a web application firewall that can work either embedded or as a reverse proxy. It provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis.

Pangolin is an open-source, self-hosted tunneled reverse proxy server that brings identity-aware access control and dashboard management to exposing private services securely. It allows you to connect applications and resources behind firewalls or NATs to a central hub, using encrypted tunnels rather than opening public ports or relying entirely on VPNs. With Pangolin you can route traffic from across distributed networks, enforce contextual access rules (such as SSO, geolocation, time of day, IP restrictions), and manage all of your exposed resources in one dashboard. It supports multi-site deployments and highly-available node architectures, enabling you to own your infrastructure yet still get orchestration and control benefits. Pangolin works well for individuals, teams or organizations that need to expose internal web apps, APIs, or services, while maintaining strong authentication, auditing and governance.
