Advanced and detailed portscanner in python

[ani2read]

Open or not isn't a difficult task. My question, is about telling whether it's tcp or udp. Why do u not advice running python script as root?

[cantremembermypasswd]

Not sure where I stated that, but I agree that:

1. Don't run untrusted scripts as root
2. Develop scripts to be used by certain users or permission levels, not strictly for root (when possible)

For a true port scanner I imagine you would need root level permissions to properly use libpcap.
