comment Does 802.1X and RADIUS prevent rogue APs?
The AP is not the authentication server, and only the authentication server knows the certificate.

comment Shell SIGKILL Keybinding
I guess he's not actually talking about the line editor - if he's typing into the shell, there would be no running foreground process, right? The shell would never actually see the keypresses if there is a foreground process running and connected to the current tty.

comment TCP and fair bandwidth sharing
But isn't that how TCP itself handles congestion control? Packets are dropped, and the sender throttles back. I just want the packets to be dropped "fairly", i.e. if one user consumes more than his fair share, only (or primarily) his packets will be dropped, and only his flows will have to throttle back. Of course that would imply metering each user's current packet rate, and dropping accordingly. Is that possible?

But I can always drop that packet, thereby forcing TCP to throttle back, right? I'm hoping that the offending flows are TCP or TCP-like regarding their congestion control.

comment Why does NAT64 require DNS rewriting?
So that scenario was not considered when IPv6 was designed (or considered not to be relevant to the core standard), and DNS64 is the hack that makes it work? Or am I missing something? Would defaulting to that prefix in case no IPv4 interface is available by all IPv6 hosts break anything?

But that's 6to4, right? There would be no way for the hosts in the network to have "native", routable IPv6 addresses.

comment Why does NAT64 require DNS rewriting?
Ok, so I guess there is a pretty good reason why it is being used, but just out of curiosity: Why is there no well-known prefix? Hosts could automatically select it in case there is no IPv4 route to the target host, and all the DNS hassle could be avoided. (Hardwired IP addresses would still work, too.) Or would that interfere with the sockets API (after all, a requested IPv4 connection would suddenly be an IPv6 one)?
