Exactly 20 years ago, Chris Demetriou made the first commit, which marked the establishment of the project repository and branches from the code base 386BSD 0.1. The first release came a few weeks later – on April 19.

Among the reasons for the creation of the new OS mentioned divergence of views with developers 386BSD, as expressed in the desire to move to a more open development model, to unite in a working product accumulated in the community and to integrate external patches in individual developing a collection of network applications.

Open SourceIn OpenBSD source tree code integrated with the new daemon identd IDENT protocol implementation (RFC 1413), designed to identify the user organization, establishing TCP-connection.

New identd developed in the depths of the OpenBSD project as a safe, high-performance replacement of the original BSD identd, caused by inetd.

New implementation itself handles the connection and starts to form a background process, and connections are handled in non-blocking mode using libevent. At the expense of the competent organization handling network connections and avoid the overhead associated with the launch of a new process for each request using inetd, the new implementation can dramatically increase the performance of the service IDENT. In addition, the new identd possible to parallel processing of client connections. Continue reading
