Re: [93attendees] Network experiment during the meeting

["Eric Vyncke (evyncke)" <[e-mail]>]

Like Toerless, I find interesting this discussion when we all know that WiFi (unless WPA is used) is 'broadcasted' everywhere.

During some previous IETF meetings, I used https://github.com/evyncke/mcast6 for one hour or two to collect aggregated statistics on IPv6 NDP & other multicast packets. Obviously, anybody could do it as the WiFi AP are configured in such a way that mcast packets are forwarded

I asked Jim and Joel this but no response as yet. Maybe you have an opinion

This appears to be a benign experiment, but would it impact operations, or in your opinion, intrude on privacy?

I do not expect it to impact operations, and, as the device collecting data will be in the NOC, we can easily disable it should there be any concerns.

Both Jari and I have discussed privacy concerns with Rolf and, at the level of information I have, I believe Rolf will be protecting our attendees privacy.

That said, I'm not a security guy and a full analysis of the security implications would probably need to be done by a security guru.

However, note, with or without our permission, any attendee can collect the same information Rolf is collecting.

Typically experiments involving the production network run past the
network staff and the IAD/IAOC or IETF chair.

Joel,

Rolf contacted me a while ago and I had him contact Jari for approval of this "experiment". Jari has approved it.

The device will sit in the NOC where we can easily disable it if there's an issue.

I haven't seen this float by so I don't know if it has or not but if
you haven't, I'd suggest doing that.

 Rolf's done his job. I got distracted by traveling and trying to get the network working to forward this to the NOC list. I'll do that asap.

Chris.

thanks
joel
