Network connection ports are sockets, yes, but *nices can also have sockets
as files (run "ss -x" to see which ones are open on your system, and "ss -lx"
to see the listening ones).

On my system, they're mostly in the 20000 range, but if those are inode
numbers, they could vary a good deal on different systems.

There are several inode-related settings in /proc/sys/fs, but I admit I don't
know exactly what each one means. You'd need to ask more knowledgeable people
on this list.

Your future is whatever you make it.
So make it a good one!
