Hi Thomas, Thanks for the report. On Linux boxes I can also confirm this behaviour since Nmap 6.0. We are aware of it and we are trying to fix it (there are at least two other bugs which are related to the network interfaces and routes). We'll provide patches soon, and hopefully other Nmap developers will test them on their Windows machines. Thanks. On Thu, Jun 21, 2012 at 10:31:51PM +0200, Thomas, Ulrich H. wrote:
Hello, there is someting strange in the routing table of nmap as shown below. All routes are set to eth1 interface, but e.g. 172.16.0.0/16 should be eth0. If I start nmap without the -e eth0 option, nmap don't discover the a host on this network. System is Windows 7 x64. nmap -n -sP 172.16.14.10 Starting Nmap 6.01 ( http://nmap.org ) at 2012-06-21 22:29 Mitteleuropõische Sommerzeit Note: Host seems down.
