iputils

USE flags

• arping - Build and install arping -- tool for sending ARP requests to peers (see also net-analyzer/arping)
• caps - Use Linux capabilities library to control privilege
• clockdiff - Build and install clockdiff -- tool for comparing clocks via ICMP packets
• doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• filecaps - Use Linux file capabilities to control privilege rather than set*id (this is orthogonal to USE=caps which uses capabilities at runtime e.g. libcap)
• idn - Enable support for Internationalized Domain Names
• nls - Add Native Language Support (using gettext - GNU locale utilities)
• rarpd - Build and install rarpd -- server for handling RARP (reverse ARP) requests; generally only used by old systems
• rdisc - Build and install rdisc -- server for the client side of the ICMP router discover protocol
• static - !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
• test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
• tracepath - Build and install tracepath -- tool for tracing network paths for discovering MTU values
