Re: Using nping echo mode over IPv6

["Luis MartinGarcia." <luis.mgarc () gmail com>]

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

Please let me know if this fixes the issue.

Thank you and best regards,
