BSD software

BSD licenses

BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software.

See IPFilter and BSD licenses

DragonFly BSD

DragonFly BSD is a free and open-source Unix-like operating system forked from FreeBSD 4.8.

See IPFilter and DragonFly BSD

In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. IPFilter and firewall (computing) are firewall software.

See IPFilter and Firewall (computing)

FreeBSD

FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD).

See IPFilter and FreeBSD

GNU General Public License

The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses, or copyleft, that guarantee end users the four freedoms to run, study, share, and modify the software.

See IPFilter and GNU General Public License

Hewlett Packard Enterprise

The Hewlett Packard Enterprise Company (HPE) is an American multinational information technology company based in Spring, Texas.

HP-UX

HP-UX (from "Hewlett Packard Unix") is Hewlett Packard Enterprise's proprietary implementation of the Unix operating system, based on Unix System V (initially System III) and first released in 1984.

See IPFilter and HP-UX

Illumos

Illumos (stylized as illumos) is a partly free and open-source Unix operating system.

See IPFilter and Illumos

Ipfirewall

ipfirewall or ipfw is a FreeBSD IP, stateful firewall, packet filter and traffic accounting facility. IPFilter and Ipfirewall are BSD software and firewall software.

See IPFilter and Ipfirewall

Iptables

iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. IPFilter and Iptables are firewall software.

See IPFilter and Iptables

Kernel (operating system)

The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system.

See IPFilter and Kernel (operating system)

Linux

Linux is both an open-source Unix-like kernel and a generic name for a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.

See IPFilter and Linux

Loadable kernel module

In computing, a loadable kernel module (LKM) is an object file that contains code to extend the running kernel, or so-called base kernel, of an operating system.

See IPFilter and Loadable kernel module

NetBSD

NetBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD).

See IPFilter and NetBSD

Network address translation

Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.

See IPFilter and Network address translation

NPF (firewall)

NPF is a BSD licensed stateful packet filter, a central piece of software for firewalling. IPFilter and NPF (firewall) are BSD software and firewall software.

See IPFilter and NPF (firewall)

Open-source software

Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose.

See IPFilter and Open-source software

OpenBSD

OpenBSD is a security-focused, free and open-source, Unix-like operating system based on the Berkeley Software Distribution (BSD).

See IPFilter and OpenBSD

OpenIndiana

OpenIndiana is a free and open-source illumos distribution descended from UNIX System V Release 4 via the OpenSolaris operating system.

See IPFilter and OpenIndiana

Oracle Corporation

Oracle Corporation is an American multinational computer technology company headquartered in Austin, Texas.

Oracle Solaris

Solaris is a proprietary Unix operating system originally developed by Sun Microsystems.

See IPFilter and Oracle Solaris

PF (firewall)

PF (Packet Filter, also written pf) is a BSD licensed stateful packet filter, a central piece of software for firewalling. IPFilter and pF (firewall) are BSD software and firewall software.

See IPFilter and PF (firewall)

Stateful firewall

In computing, a stateful firewall is a network-based firewall that individually tracks sessions of network connections traversing it.

See IPFilter and Stateful firewall

Theo de Raadt

Theo de Raadt (born May 19, 1968) is a South African-born software engineer who lives in Calgary, Alberta, Canada.

Unix-like

A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification.
