oidentd is a configurable and RFC 1413 compliant ident protocol server. It runs on Linux, FreeBSD, OpenBSD, NetBSD, DragonFly BSD, and others.

Ident is primarily used on IRC to detect and prevent abuse of shared networks and other services.

Starting from oidentd 2.3.2, release signing keys are signed with a new key signing key. This key has been signed with the previous signing key. Please see the installation instructions for more information.
