pfSense

pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding ... [More] bloat and potential security vulnerabilities to the base distribution. pfSense is a popular project with more than 1 million downloads since its inception, and proven in countless installations ranging from small home networks protecting a single PC to large corporations, universities and other organizations protecting thousands of network devices. This project started in 2004 as a fork of the m0n0wall project, but focused towards full PC installations rather than embedded hardware. [Less]

Firewall Builder

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 ... [More] abstract model and the same GUI for different firewall platforms. It currently supports iptables, ipfilter, ipfw, OpenBSD pf, Cisco PIX, and FWSM. [Less]

Carp::Parse::Redact

Carp::Parse::Redact - Parse a Carp stack trace into an array of caller information, while redacting sensitive function parameters out.

UCARP

UCARP is a portable implementation of the CARP protocol. UCARP allows a couple of hosts to share common virtual IP addresses in order to provide automatic failover. It is a portable userland implementation of the secure and patent-free Common Address Redundancy Protocol (CARP, OpenBSD’s ... [More] alternative to the patents-bloated VRRP). Strong points of the CARP protocol are: very low overhead, cryptographically signed messages, interoperability between different operating systems and no need for any dedicated extra network link between redundant hosts.

Carp::Parse

Carp::Parse - Parse a Carp stack trace into an array of caller information with parsed arguments.

nginx-upstream-carp

nginx_upstream_carpThis module achieves partial CARP(Cache Array Routing Protocol) support in nginx upstream module. It chooses the backend server with a steady order. The same URL will always be forward to the backend with the same order when failure occurs. The score is calculated from ... [More] server's weight and hash value of server name and URL. Detail information is in http://icp.ircache.net/carp.txt. This module do not support Array Membership Table. All the weight value are from the upstream server's weight. INSTALLATION This module needs libmath++. compile nginx with the following addition option: --add-module=/path/to/this/directoryEXAMPLEupstream backend { server 192.168.0.100 weight=1; server 192.168.0.101 weight=2; server 192.168.0.102 weight=3; server 192.168.0.103 weight=4; carp $scheme://$host:$server_port$request_uri; }DIRECTIVEScarp syntax: carp [hash_string] default: $uri context: upstream description: Enable the nginx_upstream_carp module and set the string to be hashed. The hash_string can contain several variables. With the hash value, the request will be routed to the highest score backend server. Note: This is a third-party module. And you need careful test before using this module in your production environment. Questions/patches may be directed to Weibin Yao, yaoweibin@gmail.com. [Less]
