Hi Bill -
You are correct we don't need root access if:
1) The webserver is already installed.
2) The webserver is not binding to a reserved port.
There are some problems though with what you're suggesting. First,
firewalls. I know I tell my firewall to reject the hell out of any
packet coming in on a port that I haven't specifically told it that it
was okay to listen to. Root access would be required to punch a hole.
But then what port would you use? You wouldn't want 80 on the off chance
that another webserver was running. You wouldn't want it random,
otherwise you couldn't publicize the existence of the server to others.
It could indeed run with the permissions of the user on a high enough
port, but when does it run? *nix machines are multi-user. So I wouldn't
want stuff only shared when I'm logged in; if I'm out sick and a
co-worker wants to access one of my public files, they couldn't. And if
more than one user was logged on at a time? Would each of them have
their own webserver on their own port? Or if they used the same server,
under whose permissions would the server run as?
To me, the only way around all of these is if the server runs as root.
It's the only way to have a fixed port, to have multiple users able to
share files at the same time, and to have the server able to access
multiple users' files.
But we still have the problem of collisions with Apache or other
servers. And the firewall. And some of the others I mentioned.
