I am new to xinetd, but trying to mimic an old machine on site that is using it. So I copied the configs on that machine (changing names where appropriate) and then tried to start xinetd. Then realizd, it is not installed on my fresh centos7 install. So I yum installed. Then systemctl enable xinetd then I did a systemctl start xinetd and then a systtem status xinetd which is what makes my brain hurt, it shows it is removing my service (kcamera) but I have no idea why or why. Then a sudo lsof -i -P -n | grep LISTEN shows no xinetd running at all.
Curious what I am missing. (I haven't touched the firewall if that makes a difference).
[root@dhcp-093 etc]# systemctl status xinetd

I had possibly wrongly assumed that just adding my kcamera to /etc/xinetd.d was enough to get things rolling once xinetd started. Though a LS in that folder reveals a lot of files like tcpmux-server which is one of the ones above it said it was 'removing'.
not sure what else to try, look for, or configure.

I don't see a port number defined in your xinetd service. How can it know which port to listen on without this? Add the correct port number back into the configuration.
