THE PROBLEM: | |
Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.) | |
THE TEMPTINGLY EASY BUT TOTALLY WRONG SOLUTION: | |
Alter the port the script talks to from 8000 to 80: | |
}).listen(80); |
