|
| This utility takes a list of IP addresses/ranges and scans them for commonly used web ports, showing the web server type for each active web port. You can select which ports to scan from a fixed list of common web ports. Port 80 is the usual one to look for and 443 should be selected if you are looking for web servers running HTTPS. |

| On Windows XP Service Pack 2, YAPS may appear to be very slow at scanning. This is due to a Microsoft limiting the number of outgoing TCP connection attempts. Google for 'Event ID 4226' for more information. |
