    What this does is get the telnetd service kicked out by inetd..by using a
    similar method with numerous rapid connections, you can shut-down any tcp
    service running under inetd, ie. ftpd, identd, etc, just by connecting to
    the port each service is listening on. Until a fix is out, it might be
    wise to crontab a HUP to inetd every few minutes, so that if somebody
    takes out your telnet service, you can log back in eventually.
