ruledelt

ruledelt is a command-line utility designed for managing firewall rules. It allows users to add, delete, and list rules for network traffic filtering. The tool primarily interacts with the netfilter framework in the Linux kernel, which is the underlying mechanism for packet filtering and manipulation.

The primary function of ruledelt is to simplify the process of modifying firewall configurations. Instead of manually editing complex configuration files or using lower-level tools, users can employ ruledelt for more straightforward rule management. It supports specifying various parameters for rules, such as source and destination IP addresses, ports, protocols, and actions like ACCEPT or DROP.

Typically, ruledelt would be used in conjunction with a firewall daemon or script that loads the rules into the kernel. Its direct manipulation of the kernel's netfilter tables makes it a powerful tool for system administrators and network engineers who need fine-grained control over network security policies. While specific implementations and features might vary, the core purpose of ruledelt remains consistent: efficient and programmatic management of firewall rules.
