View the Project on GitHub

oidentd is an RFC 1413 compliant ident daemon that runs on Linux, FreeBSD, OpenBSD, NetBSD, DragonFly BSD, and some versions of Darwin and Solaris.

oidentd is used primarily by universities and providers of shell accounts and public IRC bouncers to fight abuse by allowing servers to identify the owners of incoming connections.


For a complete list of features, please consult the manual pages or run oidentd --help.

All releases are signed with PGP key EB19 A17D 8165 4263 5D13 B19F E3E8 FA19 DC9A 1AA9. It is highly recommended that you verify the signatures of releases before installing them.
