xinetd (https://github.com/xinetd-org/xinetd) is an open source replacement for inetd which combines inetd, tcpwrappers and a considerable amount of other functionality. RedHat 7 (and perhaps other distributions) now appears to use xinetd.
The install scripts for UNIX distributions up to 22.214.171.124 do not support xinetd although it is relatively trivial to manually add the OOB Server to the xinetd configuration post install.
To install the OOB Server under xinetd manually:
 Locate the xinetd.conf file. It is usually /etc/xinetd/conf.
 Examine the xinetd.conf file and look for a an includedir command.
If you find an includedir command change to that directory and add
a new file called esoobserver that looks like this:
socket_type = stream
protocol = tcp
wait = no
user = root
server = /bin/bash
server_args = /usr/local/easysoft/oob/server/server
disable = no
Make sure the server argument is a valid shell on your system.
 If in  you did not find an includedir command then the above
entry can be added to the end of your xinetd.conf file.
 Once you have made your changes you need to tell xinetd to reread
its configuration files. You usually do this by sending it a USR1
signal e.g. kill -USR1 process_id_of_xinetd. However, as xinetd
can be configured to use different signals you should check the
signal your xinetd requires.
