Binding on ports < 1024 on Linux require elevated permissions, no?
If so, somebody please elaborate.
That's a Linux restriction/feature - must be superuser to use the low port
numbers.

I recommend fronting Tomcat with a web server like nginx or httpd, but see also two solutions from http://georgik.rocks/tomcat-7-listen-on-port-80-linux-debian/

1) have Tomcat listen on a higher port and redirect traffic from port 80 to the higher port in iptables
2) set `AUTHBIND=yes` om /etc/defaults/tomcat7
