True. But the original example does not follow the finger protocol. In a
finger server conversation the client has to provide the username. For
our example we'll finger root:
steve:~$ telnet localhost 79
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
root
There is no such user.
Connection closed by foreign host.
steve:~$
The original example is similar to daytime in that merely connecting to
the port results in a reply:
steve:~$ telnet localhost 13
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
