IpTables Rope
Rope is a programming language that allows developers to write extensions to the Iptables/Netfilter components of Linux using a simple scripting language based on Reverse Polish notation. It is a scriptable Iptables match module, used to identify whether IP packets passed to it match a particular set of criteria or not. Rope started life as a project to make the "string" match module of Iptables stronger and evolved fairly quickly into an open-ended scriptable packet matching mechanism.

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. The filters are organized in different tables, which contain chains of rules for how to treat network traffic packets. Different kernel modules and programs are currently used for different protocols; ''iptables'' applies to IPv4, ''ip6tables'' to IPv6, ''arptables'' to ARP, and ' to Ethernet frames. iptables requires elevated privileges to operate and must be executed by user root, otherwise it fails to function. On most Linux systems, iptables is installed as and documented in its man pages, which can be opened using man iptables when installed. It may also be found in /sbin/iptables, but since iptables is more like a service rather than an "essential binary", the preferred location remains . The term ''iptables'' is also commonly used to inclusively refer to the kernel-level componen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
