So DJB's program basically has a large listen queue, and goes into

If that's the case, then there's still a DOS - just fill the listen
queue with so much stuff that connections aren't serviced for a long
I wonder how many years it takes for people to realise that DOS based on
service flooding is not something you can be immune to. Does it really
take one DDOS per person to realise this simple truth? For every single
method you invent there are 10 other methods to smash your box into nirvana
Purpose of inetd was never security, nor protection of box from stupid
applications it is called to start that can consume all resources.
Inetd fulfills its purpose. If you need more, you need something else.
If you want security separation, use state-tracking firewall. If you want
to be immune from DOS, unplug from internet. All else is pointless whining.
Imagining that inetd should evolve into strong firewall is as bizarre as
it can get.
