-If you want to be able to run a process that responds to requests on a
[Port
] below 1024 without running it as the SuperUser, a simple approach is to have it bind to some port above 1024, then configure a lower layer in the NetworkStack to do the legwork
. On [Linux], a convenient way to achieve this is by using iptables(8):
-
-<pre>
-iptables --table nat -A PREROUTING -p tcp --dport <i>$external_port</i> -i eth0 -j REDIRECT --to-ports <i>$local_port</i>
-</pre>
-
-This way, you could have a process bind to port 8080 locally, but have it appear to outsiders as though it was listening on port 80.
-
-(Don’t forget to issue something like <tt>/etc/init.d/iptables save</tt> so this configuration won’t be lost on reboot.)
