Few days back I learn about super server in networking. Then I looked for /etc/inetd.conf and /etc/xinetd.d and found neither of them in Ubuntu.
Note:
I know only these two types of super server configuration file in Unix like system.
Is Ubuntu still running inetd super server or it has been removed from system?
If it's running inetd super server then where it's located?
On Ubuntu, Upstart takes care of starting services. Restarting services as inetd can do is often not needed as the programs like sshd just start and run in the background, instead of being restarted again and again.
If you install some serial ports you might have to install (x)inetd to allow login over a serial line, but I haven't seen any need recently for other uses of inetd. That is not to say that it doesn't work, just that it has been marginalized by stability of specific daemons and no need to release memory that much on modern machines (like in the old days).
Systemd2 once it percolates through from Debian to Ubuntu supports, AFAIK, more of inetd functionality than Upstart, but I don't know if it will prohibit its use.
