+ip_unprivileged_port_start - INTEGER
+ This is a per-namespace sysctl. It defines the first
+ unprivileged port in the network namespace. Privileged ports
+ require root or CAP_NET_BIND_SERVICE in order to bind to them.
+ To disable all privileged ports, set this to 0. It may not

If set, allows processes to bind() to non-local IP addresses,
which can be quite useful - but may break some applications.
