Paranoid TelnetD is written in straight C with few dependencies. It is intended for use with embedded or legacy devices (like the hand-scanners used in warehouses) that communicate via telnet. It features: 'telnet only' user accounts, separate from the system authentication (so only the specified usernames/passwords can login via telnet, and only via telnet); user, IP address, and MAC address whitelisting/blacklisting; chrooting with 'bind mounts' to allow access to certain directories under the chroot jail; and 'honeypot mode' in which all authentication fails and all events are logged at syslog 'crit' level.
