Sanewall is a firewall builder for Linux that uses an elegant language abstracted to just the right level. This makes it powerful and easy to use, audit, and understand. It allows you to create very readable configurations even for complex stateful firewalls. Sanewall can be used for almost any purpose, including control of any number of internal/external/virtual interfaces, control of any combination of routed traffic, setting up DMZ routers and servers, all kinds of NAT, providing strong protection (flooding, spoofing, etc.), transparent caches, source MAC verification, blacklists, and whitelists. Newer versions abstract the differences between IPv4 and IPv6, allowing you to define a common set of rules for both, while permitting specific rules for each as you need. Sanewall is a fork of FireHOL and can make use of existing FireHOL configurations.
OpenConnect server (ocserv) is an SSL VPN GNU/Linux server. Its purpose is to be a secure, small, fast, and configurable VPN server which depends on standard protocols like TLS 1.2 and Datagram TLS. It implements the AnyConnect SSL VPN protocol and is compatible with the OpenConnect VPN client and other Anyconnect SSL VPN clients.
libjmmcg is a basic, low-level library with pretensions to implementing features above and beyond (but not necessarily better than!) those implemented within the Standard C++ Library and the Boost Library. It features a library for multi-core or multi-chip SMP parallelism, a suite of hashing algorithms, functions for raising numbers to integer powers, a generic factory wrapper and a generic, multi-threaded, read-only cache (which uses PPD), arguably the world's worst sorting technique, trace output, exceptions that have the file, line, revision, function, and argument details, string utilities, logging, simple command line processing, and much more.
genpuppet is a script to automatically generate a puppet manifest based on a series of user inputs. Think of it as a kernel "make config" for puppet. With genpuppet, the most frequently used resources are prompted for so one can quickly generate a working manifest without having to concentrate on syntax and spacing.
RCP100 is a modular router control plane for Linux platforms. It can be used as a standalone router, or it can be deployed as an embedded router in a virtualized environment. The modular architecture allows rapid introduction of new features and functionality, including support for custom hardware. It features a command line interface, Web interface, Telnet, FTP, and TFTP access, an NTP client and server, a DNS proxy cache, a DHCP relay, static routes, blackhole routes, static ARP, proxy ARP, RIP version 2 (RFC 2082, RFC 2453), OSPF version 2 (RFC 2328), and Access Control Lists.
Revised is a visual editor (or wizard/assistant/GUI) for Ren’Py, the visual-novel game editor. Ren'Py has a lot of capabilities, and Revised's purpose is not to allow everything that Ren'Py can do, just some of the basics. You can think of it as a step-by-step wizard to create the skeleton of a Ren'Py game.
