important sites use ProFTPD. Sourceforge.net is a good example (this site has a total of 3,000 open-source projects, and its load is not small !). Some Linux Publishers also use ProFTPD on their main FTP site, and WuFTPD is only used by two major Linux Publishers (SuSE and Caldera. Another advantage of ProFTPD is that it can run both from inetd and as a separate daemon. This can easily solve some problems

can run both from inetd and as a separate daemon. In this way, some problems caused by inetd can be easily solved, such as denial of service (DoS) attacks. The simpler the system, the easier it is to ensure system security. WuFTPD either review all source code (very difficult) or completely rewrite the code. Otherwise, WuFTPD must be replaced by ProFTPD. Telnet Telnet is very insecure. It uses plain text to send passwords. Its safe alternative is Op
