I tried looking into the /etc/ folder, but I couldn't find it. I even did a full system scan using
find / -name inetd.conf
still in vain.
From the inetd man page
Upon execution, inetd reads its configuration information from a
configuration file which, by default, is /etc/inetd.conf.
If it's not there, create it there as it's the default.
and next time you look for something use locate inetd
