The answer is simple

Since, I complied tcpwrapper in /usr/local/tcp_wrapper-7.6 directory. It will
created a file "tcpd" in that directory. you SHOULD LEAVE IT THERE rather than
move "tcpd" file to other places. So the inetd.conf shoul be modified as below:


ftp stream tcp nowait root /usr/sbin/in.ftpd in.ftpd


ftp stream tcp nowait root /usr/local/tcp_wrapper7.6/tcpd


kill -HUP PID

That is the solution.
