Hi Juhani, I've been looking into this. The echo client/server functionality over IPv6 had never been properly implement (my fault). I've just committed a series of patches that may solve the issue. The patches are in a development branch. Here are instructions on how to download the code: svn co https://svn.nmap.org/nmap-exp/luis/nmap-npingchanges cd nmap-npingchanges ./configure && make sudo make install And here's what I get: SERVER$ sudo ./nping --es public -e vmnet2 -6 Starting Nping 0.6.26SVN ( http://nmap.org/nping ) at 2013-10-07 23:03 CEST Packet capture will be performed using network interface vmnet2.

My mail agent says that the files were attached, I'm leaning more toward the mailing list software filtering them out (maybe I need some sort of whitelist entry first). We're trying again in just a moment with my friend Toni. Btw, if you didn't, can you please run with the -d5 flag? Thanks. Best regards, Luis MartinGarcia.
