The only alternative I am aware of would be to 37 * register as a heuristic dissector for pretty much every possible protocol 38 * there is, which seems unreasonable to do to me. To fully support Wake-On-Lan dissection 34 * though, we would need a way to have this dissector called only if the frame 35 * hasn't already been classified as some other type of dissector. 30 * 31 * To keep things simple, this dissector will only indicate a frame as 32 * Wake-On-Lan if the MagicPacket is found for a frame marked as etherytpe 33 * 0x0842 or if it's a UDP packet. Ether-wake implements it as an Ethernet 27 * frame with ether type 0x0842 (ETHERTYPE_WOL), and the other tools all seem 28 * to implement it as a UDP packet, both with the payload as nothing but the 29 * MagicPacket. 22 * 23 * From what I can tell from the tools available, even though the white paper 24 * indicates that the so-called, 'MagicPacket' can be located anywhere within 25 * the Ethernet frame, in practice, there seem to be only 2 variations of the 26 * implementation of the MagicPacket.

17 * 18 * In addition, testing of the dissector was conducted using 2 utilities 19 * downloaded from and 20 *, as well as with the ether-wake utility 21 * on a Linux Fedora Core 4 system. 14 * 15 * The 'Wake On LAN' dissector was written based primarily on the AMD white 16 * paper, available from. This dissector is 12 * a heuristic one though, so appropriate changes have made to the template 13 * as needed.

It uses the template from SVN23520 docs/vloper, which 11 * was the latest one available at the time of this writing.
