To disable telnetd, edit /etc/inetd.conf and comment out the telnetd entry and then refresh inetd.
In /etc/inetd.conf there is a line like

  telnet stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetd

which can be found by search the string telnet. Comment it out by putting the pound character ("#")
at the beginning of the line so that the entry looks like

  #telnet stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetd
