"Out of band" means other than the communications medium being discussed. If it travels over the ethernet wire, it's ethernet, and explicitly NOT out of band. Ditto Wifi.
In the case of vPro, "out of band" means that it's using the same wires (or frequency) that the NIC is connected/tuned to, but it's being processed outside of the OS's. So before your software firewall even sees the packet come in, the NIC consumes it and passes it along to the vPro chip to be handled. Since these control packets are not TCP/IP and not using the OS's networking stack, they can't traverse network segments (routers) unless explicitly forwarded. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAEBAgAGBQJP7LseAAoJEMco5sYyM+0w3D8H+gJ14978mabzuD9eke5IkHlk 0zfkGMKcvr4fHDyBSZStsMqPTN3toBBgcQGnTAO4F/ZuWSkccaJoHfbxfh9B25SP 7cbqgZu82QqBlEE4jEsr5Vm6bhP66FrzkJ6/kMtI1vjZgOq6+vl0RGjvYt7acweY Hw7yQlzqpEJD1MfuyZ0PY5W9LsnDAa2sqzL8Mp+ok93ukaTuyho89pZBrnfRtitV SVWygAopxPoFtDu922asC+i5o6fbsNJMIeDbOSau8fsXvPCG5uPlgCGVdXhyofBQ mzf3oi+bdF5NHY9FyGl2K6l92cfr4lwulUrXQZsAeAMSnWxVRmmCytGkxN09AfY= =5FO/ -----END PGP SIGNATURE----- _______________________________________________ Freedombox-discuss mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss
