The stunnel program is designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server. It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. It will negotiate an SSL connection using the OpenSSL or SSLeay libraries. It calls the underlying crypto libraries, so stunnel supports whatever cryptographic algorithms you compiled into your crypto package.
Tinyproxy is a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems. Designed from the ground up to be fast and yet small, it is an ideal solution for use cases such as embedded deployments where a full featured HTTP proxy is required, but the system resources for a larger proxy are unavailable.
Ziproxy is a high-performance forwarding (non-caching) HTTP proxy that gzips text and HTML files, and reduces the size of images by converting them to lower quality JPEGs or JPEG 2000. It is intended to increase the speed for low-speed Internet connections (mobile, dial-up, other). It's suitable for both home and professional usage. Ziproxy is fully configurable and also features transparent proxy mode, HTML/JS/CSS optimization, operation in daemon mode, a detailed access log with compression statistics, basic authentication, and more.
goMyPlace is a reverse proxy software and a daemon that runs on the client side. The system features elements of a remote access system. The proxy runs smart data hash based caching, so a daemon running on the client uploads a file only once. All URL links are static and friendly to search engines. An open reverse proxy hides the IP address of the HTTP servers and can protect sensitive content. An HTTP server hides behind the reverse proxy, never accepts incoming connections, and can be kept behind a NAT and firewall.
Quassel IRC is a modern, cross-platform, distributed IRC client, meaning that one or more clients can attach to and detach from a central core, much like the popular combination of screen and a text-based IRC client, but graphical. In addition to this unique feature, it aims to be a comfortable chatting program.
Pagekite is software to make servers on "localhost" visible to the wider Internet. It can be used by Web developers to show off their works in progress to clients or colleagues, embedded developers who need direct access to devices in the field, or as an alternative to dynamic DNS for individuals/hobbyists who would rather host their own content than rely on 3rd party hosting. It creates and maintains a tunnel between your server on localhost and a remote "front-end" (a reverse proxy). Only the front-end has to have a visible IP address; the server itself can reside on a heavily firewalled computer, a mobile device, or even an anonymous node on the Tor network.
