Experiencing the following issue with Nmap on Windows?
$ nmap -P0 -sS -T5 0.0.0.0
Starting Nmap 7.70 ( https://nmap.org ) at 2019-06-04 03:14 ric
dnet: Failed to open device eth0
It appears that some version of Npcap (or WinPcap) is causing issues. Updating Npcap to version 0.995 solve this issue.
If you are running Windows 10 build 1607 and use WinPcap, please know that a strict driver signing requirement has been introduced from this version and does work with WinPcap, please install Npcap instead which is fully compatible with latest Windows 10 releases.
