RE: Quiet Nmap 7.25BETA1 release

["Rob Nicholls" <robert () robnicholls co uk>]

It looks okay so far on the Windows x64 side of things. Nmap and Npcap appear to work fine on Windows 8.1, Windows 2012 
R2 and Windows 10 Pro. I also have it working on an old Windows 8.0 VM, although I did initially get the warning “dnet: 
Failed to open device lo0” when scanning 127.0.0.1 on a Windows 8.0 VM (running under Hyper-V) before I rebooted and 
reinstalled Nmap/Npcap, but now it’s fine (it is worth noting that Windows 8.0 hasn’t been supported by Microsoft in 
several months). If I find time I’ll try it on an old Server 2008 host (which should work the same as Vista) and build 
a few x86 VMs for further testing.

Is there a way to tell which nsock engine is in use during a scan, now that Windows apparently supports poll and 
select? I’ve gone with whatever is the default on Windows when testing, but I can’t see anything obvious in Nmap’s 
output even with -d9 when I specify the --nsock-engine as poll or select.

Hi folks!  We've quietly updated the Nmap download page with links to a new Nmap 7.25BETA1 release:

https://nmap.org/download.html

This is the first release to include the new Npcap (http://npcap.org) Windows packet capturing library that we've been 
working on for 3 years!  There are dozens of other enhancements as well.  I'm planning to send full release 
announcements on Monday, but please do report it on this dev list if you try 7.25BETA1 (especially the Windows builds) 
and have any problems!

Cheers,
Fyodor
