How can I bind to a port under 1024 and still run as a non-root user?
I want to bind resin to port 80, but my operating system only allows root to bind to ports under 1024. If I run Resin as root, it is a security risk. How can I start Resin as root but then change the user and group id after it is bound to the port?http://www.caucho.com/resin-3.0/install/faq.xtp#How-can-I-bind-to-a-port-under-1024-and-still-run-as-a-non-root-user?Most Unix systems can simply use the <user-name> and <group-name> configuration tags.
New versions of Linux (with the new threading model) can also use <user-name> , but using "/sbin/iptables" may be a better solution. The Linux iptables maps port 80 requests to port 8080. This way, your Resin instance can start up as a normal user and listen to port 8080 without needing to start as root.
Linux 2.2.x route port 80 to port 8080
/sbin/ipchains -A input -i eth+ -j REDIRECT 8080 -p tcp –destination-port 80
Linux 2.4.x route port 80 to port 8080
/sbin/iptables -t nat -A PREROUTING -i eth+ -p tcp –dport 80 -j REDIRECT –to-port 8080

It’s exciting to see them being so ambitious and going after areas that are ripe for innovation (competition has been sorely needed - witness the skimpy amount of webmail space Yahoo offered with free email accounts until Google forced them to be more competitive). But I have to wonder if they will be able to continue taking on so many areas and at the same time be able to leverage their efforts strategically across all of the product lines. Will it all come together as a coherent set of offerings that leverage a similar user experience and take advantage of core underlying technologies in an efficient manner? It should be interesting to watch as they continue to race forward…
