The quick answer is, "nowhere." It appears that in Debian "wheezy" inetd is not installed by default. You have to do:
# apt-get update # apt-get install inetutils-inetd
That will get you where you need to be. After you configured at least one service in /etc/inetd.conf, you can do:
# dpkg-reconfigure inetutils-inetd Stopping internet superserver: inetd. Starting internet superserver: inetd.
# ps ax | grep inetd 5005 ? S 0:00 /usr/sbin/inetutils-inetd 5008 pts/0 S+ 0:00 grep inetd
Note that the inetd daemon has been renamed.
