Only root can bind a process to port 80.
Well, i dont see the point here (cause i'm a newbie), but i would like to
get this result:
1)An user contact www.myhost.com
2) the resolver asks to the DNS for that name, and the DNS answers with the
pair IP:PORT (ie www.myhost.com:8080)
It doesn't work like that. DNS knows nothing about port numbers. HTTP = 80, HTTPS = 443, that's a browser thing, not a server thing. If a user types "http://your.host.com"; in their browser, the browser is going to contact port 80...plain and simple and there's no changing it.
You'll need one of the following: 1) proxy, 2) port forwarding (like a proxy but could be done with something like SSH), 3) URL forwarding service (like zoneedit.com), or 4) a redirect like you've mentioned.
Ports under 1024 are reserved for security reasons. Very good security reasons, and chances are the only people you will find who will disagree with the restrictions on ports less than 1024 will be newbies (also for good reason).
For example, how would you like it if just any user on a server could run a mail daemon on port 25? Port 110, sniffing POP3 passwords from other users? Etc. etc. ad nauseam.
In this way my TomCat, running at 8080, will be contacted at each request.
The actual solution (crappy) is to have an index.php file in my home
directory which redirect to www.myhost.com:8080.
If the former solution could be done, my question would be: how to do that ?
You'll need to use some sort of port forwarder or proxy. Apache can do the proxying, but you'll need to be root to configure it and test the configuration (in which case the whole thing is moot because then you could start Tomcat as root on port 80), or you'll need to use something like SSH or iptables/ipchains (or some other package) to do the forwarding for you. Either way, you still need to be root.
You could just use an external forwarding service...zoneedit.com has one.
