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)
• gcrypt - Use dev-libs/libgcrypt for md5 support
• gnutls - Prefer net-libs/gnutls as SSL/TLS provider (ineffective with USE=-ssl)
• idn - Enable support for Internationalized Domain Names
• ipv6 - Add support for IP version 6
• libressl - Use dev-libs/libressl instead of dev-libs/openssl when applicable (see also the ssl useflag)
• nettle - Use dev-libs/nettle for md5 support
• 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
• SECURITY_HAZARD - Allow non-root users to flood (ping -f). This is generally a very bad idea.
• ssl - Add support for SSL/TLS connections (Secure Socket Layer / Transport Layer Security)
• static - !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
• tftpd - Build and install tftpd -- server for the Trivial File Transfer Protocol (see also net-ftp/tftp-hpa)
• tracepath - Build and install tracepath -- tool for tracing network paths for discovering MTU values
• traceroute6 - Build and install deprecated traceroute6 tool. It's recommended to use net-analyzer/traceroute instead.
