Run script when someone telnet my server

I Have:

1) Droplets on DigitalOcean ubuntu/debian/fedora

2) Simple script that echoes something ""

I want:

When someone telnets my Server from terminal:
make my execute in his terminal and exit after that.

To sum up, I need something like this(check this out):



sudo apt-get install xinetd telnetd

/etc/xinetd.d/telnet file content:

service login
    port            = 23 
    socket_type     = stream
    protocol        = tcp
    wait            = no
    user            = root
    server          = /usr/bin/       
    server_args     = test

/etc/xinetd.conf content:

# Please note that you need a log_type line to be able to use log_on_success
# and log_on_failure. The default is the following :
# log_type = SYSLOG daemon info
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30

includedir /etc/xinetd.d

/etc/inetd.conf content:

telnet      stream  tcp nowait telnetd  /usr/bin/

Restart xinetd:

/etc/init.d/xinetd restart

EDIT: Don't forget

chmod +x /usr/bin/
