I've run across two problems with the network scanner and was hoping someone had a workaround.
1) I'm trying to index all http pages on my intranet, which is 10.0.0.0/8. The scanner doesn't allow that. I've been putting in some subnets to scan but I've run into another problem...
2) attempting a scan from an IP with no http page cancels the scan. So if I want to scan 10.1.0.0/16 (or /24) and the IP you entered (e.g. 10.1.0.1) doesn't have http running it, the scan automatically cancels.
