Thanks! The patch works. 'nmap' starts up fine and functions as expected on Ethernet interfaces. Shows the chopped MAC address for ib0 an ib1 with --iflist. As expected, IB networks can be scanned with --send-ip. Seems perfectly fine. --send-eth fails to detect other systems on the IB subnets. Strangely it does work for the local IB interface. Possibly that's a linux kernel bug since really it should not. Or possibly since the frames are local the MAC layer is entirely ignored. Since use of IB is relatively rare at stable or declining levels (10G and 40G Ethernet work well) I'd say this degree of support is "good enough." Perhaps 'nmap' can sense when it's asked to route over an IB interface (or a non-Ethernet interface) and automatically apply --send-ip. At 12:44 PM 8/28/2012 +0100, Djalal Harouni wrote:
Another point is can we send ethernet frames in this case ? or only IP packets ? which I suppose can be handled by the '--send-ip' Nmap switch. Anyway you can start with the attached patch, and see if it will work, only 6bytes of hardware address will be reported. Please try to see if you can send IP packets with Nmap on that interface.
