If I uninstall v6.01 and reinstall v5.51, it works again.  Reverse the

process and

it doesn't work without --unprivilged and even then, as I said, it works

much

slower.

  It wouldn't hurt to send the output from --iflist (inline is fine), but I wouldn't be surprised if this is caused by some of the interface/route issues that are affecting a number of other people. It appeared to work fine up until 5.51 (I think 5.51SVN-dnet-pcap2 in March 2011 was fine too), but I think the introduction of IPv6 support with 5.52 has broken something. For some reason my Nmap 6 thinks that all routes should use eth2, even for hosts on the local subnet for eth1. Djalal was looking into fixing this on Linux, but his patch seems to break the routes completely on Windows (to be fair, I wasn't expecting this to work as he did say it wouldn't). You might be able to get Nmap 6 to work correctly by forcing it to use the correct interface (e.g. "-e eth1"), assuming this is a routing issue and not some other issue - if forcing the interface works, do let us know! Using --unprivileged will force Nmap to use the OS to send it (instead of using WinPcap), and Windows will know the correct interface and route to use, which is probably why it works.

  Using -e <interface> works a treat.  I assume then that this is your known problem.  Thanks for the help.

  I think this problem is fixed in r29889 and will be fixed in the next release.  http://seclists.org/nmap-dev/2012/q3/1037  David Fifield _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
