CGIProxy is a Perl CGI script that acts as an Internet proxy. Through it, you can retrieve resources that may be inaccessible from your own machine. The user is kept as anonymous as possible from any servers. HTTP and FTP are supported, and optionally SSL. Common uses include censorship circumvention, VPN-like setups, anonymous proxies, personal proxies, and others. Options include text-only browsing (to save bandwidth), selective cookie and script removal, simple ad filtering, access restriction by server, encoded target URLs and cookies, configuration by end user, and much more (currently over 70 config options). Javascript and Flash are fully supported. Messages are in 12 languages so far. Can be installed as a CGI script, a mod_perl script, a FastCGI script, or with its own embedded secure HTTP server. An online demo is available.

ipt_pkd is an iptables extension implementing port knock detection with SPA (single packet authorization). This project provides 3 parts: the kernel module ipt_pkd, the iptables user space module libipt_pkd.so, and a user space client knock program. For the knock packet, it uses a UDP packet sent to a random port that contains a SHA-256 of a timestamp, small header, random bytes, and a shared key. ipt_pkd checks the time window of the packet and does the SHA-256 to verify the packet. The shared key is never sent.

PHREL is a per host rate limiter. It will track the rate of incoming traffic on a server and insert a chain into iptables when a configured threshold is crossed. The inserted chain may either rate limit or block the offending host for a period of time. The inserted chain is automatically removed when the offending host's traffic levels return to normal. PHREL is particularly well suited to protecting nameservers (DNS) from random hosts that flood requests, and to preventing SSH brute force login attempts.

HTTPTunnel is a simple client/server application for creating an HTTP tunnel between two machines, optionally via a Web proxy. This tunnel can then be used to wrap arbitrary TCP socket traffic in HTTP, thus allowing communications even through a restrictive firewall that only allows outgoing HTTP connections.

AppGate Security Server is an access control gateway for secure access to resources such as TCP ports, network ranges, Web pages, file shares, and remote desktops. Users connect with the cross-platform AppGate client (or any standard SSH client) and the server has a detailed configuration that says which users gain access to what under which circumstances. AppGate Free Edition is a virtual appliance running in a VMWare image and is limited to a maximum of 10 concurrent users.

Mail2sh makes it possible to carry out shell commands by email. Email is sent to a particular user on your host and the commands will be carried out if the user and password given matches ones in /etc/passwd. Commands are executed with the user's privileges, and combined with a PGP module ensures a certain level of security for use. Note that the system is not natively encrypted, so use of an encryption mechanism is highly recommended for security reasons.

Firewall Builder consists of a GUI and set of policy compilers for various firewall platforms. It helps users maintain a database of objects and allows policy editing using simple drag-and-drop operations. The GUI and policy compilers are completely independent, which provides for a consistent abstract model and the same GUI for different firewall platforms. It currently supports iptables, ipfilter, ipfw, OpenBSD pf, Cisco PIX and FWSM, and Cisco routers access lists.

Fina is a simple, robust bash script that loads iptables rules from a rules directory. As such, it isn't concerned with creating rules for you; it just helps you load them in a robust way, going back to older or safe rules when things go wrong.
