There are numerous third-party software applications for iptables that try to facilitate setting up rules. Front-ends in textual or graphical fashion allow users to click-generate simple rulesets; scripts usually refer to shell scripts (but other scripting languages are possible too) that call iptables or (the faster) iptables-restore with a set of predefined rules, or rules expanded from a ...
Uncomplicated Firewall (UFW) is a program for managing a netfilter firewall designed to be easy to use. It uses a command-line interface consisting of a small number of simple commands, and uses iptables for configuration.
Traffic associated with AT&T's Common Backbone was "split" between two fibers, dividing the signal so that 50 percent of the signal strength went to each output fiber. One of the output fibers was diverted to a secure room; the other carried communications on to AT&T's switching equipment.
A non-routing node in promiscuous mode can generally only monitor traffic to and from other nodes within the same collision domain (for Ethernet and IEEE 802.11) or ring (for Token Ring). Computers attached to the same Ethernet hub satisfy this requirement, which is why network switches are used to combat malicious use of promiscuous mode.
The Linux kernel can now be patched to allow tarpitting of incoming connections instead of the more usual dropping of packets. This is implemented in iptables by the addition of a TARPIT target. [3] The same packet inspection and matching features can be applied to tarpit targets as are applied to other targets.
Netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.Netfilter offers various functions and operations for packet filtering, network address translation, and port translation, which provide the functionality required for directing packets through a network and prohibiting packets from ...
ECN allows end-to-end notification of network congestion without dropping packets. ECN is an optional feature that may be used between two ECN-enabled endpoints when the underlying network infrastructure also supports it. Conventionally, TCP/IP networks signal congestion by dropping packets.
Remote Triggered Black Hole Filtering (RTBH) is a technique that provides the ability to drop undesirable traffic before it enters a protected network. [2] The Internet Exchange (IX) provider usually acquires this technology to help its members or participants to filter such attacks.
