WU-FTPD
From Wikipedia, the free encyclopedia
WU-FTPD (more fully wuarchive-ftpd, also frequently spelled in lowercase as wu-ftpd) is a FTP server software (daemon) for Unix-like operating systems.
It was originally written by Chris Myers and Bryan D. O'Connor in Washington University as a replacement of the BSD FTP daemon, for use in the Washington University network, primarily the large wuarchive site.
Up until early 2000s, it was the most common FTP server software in use, though its use has lessened in recent years due to availability of more feature-rich and easier to configure software, and primarily due to its lack of security and the perceived complexity of the source code. In 2001, for example, the Ramen worm used WU-FTPD as one of the possible intrusion mechanisms. Many Linux distributions have deprecated WU-FTPD in favor of other daemons.
