Re: Using nping echo mode over IPv6

[Juhani Toivonen <juhani.toivonen () cs helsinki fi>]

Hi,

Thank you. I tried this out and looks like it works on IPv6 now.

We had a further goal of using nping over a tunnelling protocol called HIP to measure its performance. Towards 
applications the implementation we use speaks IPv6, but it might be a bit picky about using raw sockets and such, we 
did not yet succeed with that one. As this might as well be an issue with our implementation I'll be looking to learn 
more first.

As for the basic IPv6 this fixed our issue.

Thanks, and best regards
