## Non-Root
|
||||||
|
|
||||||
|
You **do not need root** to map ports, but you may need root to test them.
|
||||||
|
|
||||||
|
If you're cool with allowing all node programs to bind to privileged ports, try this:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node
|
||||||
|
```
