cdrkit is CD Recording Kit, a collection of applications related to creation of optical disk media on Unix platforms, from creation of the filesystems used on such media to the actual burning process. It is heavily based on the cdrtools package (partially developed and maintained by Joerg Schilling before), but is maintained independently.
Muddleftpd is an FTP server designed to overcome the need for working as root without limiting the access protection and safety of a regular FTP server. It can operate as a replacement for wu-ftpd, or it can operate under a single UID, running without any knowledge of the system password file. Anonymous access is available, and you can create as many guest accounts as you like with the same or different properties.
