mod_ftpd is an FTP server module for Apache using the authentication system in Apache to provide anonymous or user-based FTP. Alternate chroot directories for users can be provided via a plugin system to check different data sources for the information. Currently a DBM and libdbi plugin are included. Limiting the number of users that can log into the system is also provided via a plugin system, so new limiting algorithms can be easily added in. Currently only a base limiter is provided which sets an overall cap to the each virtual server.
