peter@joule:~$ grep telnet /etc/inetd.conf
#<off># telnet	stream	tcp	nowait	root	/usr/sbin/tcpd	/usr/sbin/telnetd -a none -E /bin/bash

Not sure #<off># should be there.  Have yet to find an explanation for it.

Executes with no report to the terminal.

peter@joule:~$ telnet localhost
Trying ::1...
telnet: Unable to connect to remote host: Connection refused

Whereas the legacy telnetd accepted the connection.
That's why I used the legacy telnetd.

Tomorrow I might look for debug info for inetutils-telnetd.
