ftpd

File Transfer Protocol (FTP) server

This is the netkit ftp server. You are recommended to use one of its alternatives, such as vsftpd, proftpd, or pure-ftpd. This server supports IPv6, and can be used in standalone mode as well as in inetd-slave mode, but other servers have better long-term security screening. The server can be used with GNU/Linux, GNU/kFreeBSD, and GNU/Hurd.

ftpd-ssl

FTP server with SSL encryption support

This is the netkit ftp server with encryption support. ftpd-ssl replaces normal ftpd using SSL authentication and encryption. It interoperates with normal ftp. It checks if the other side is also talking SSL, if not it falls back to normal ftp protocol. Advantages over normal ftp(d): Your passwords and the data you send will not go in cleartext over the line. Nobody can get it with tcpdump or similar tools.
