The MAC will disappear from the ARP table after a while. But as you use the broadcast address this should not be an issue.
Enters power management. For a few years now PCs which are euro-compliant are mandated to feature a power off mode ~ 1Wh. Many (all?) machines will reach this level only with the Ethernet board fully powered off. In this mode the thing is dead, no matter of WOL will wake the computer. A bios option should be available to engage/ disable the feature. http://en.wikipedia.org/wiki/Standby_power Same goes for "green Ethernet" switches/routers. These will modulate the power applied to an Ethernet port according to the detected cable length, negotiated speed, and will power off ports which are not connected (or connected to a dead link, I suppose.) I believe the amount of power saved by port is minuscule; but considering a sparely populated 16-port switch operating 24/365, I suppose the initiative makes sense. I your router/switch is of the green Ethernet kind, you will probably find an option related to power in its management interface. http://en.wikipedia.org/wiki/Green_Ethernet HTH 4 SB 3 iPeng (iPhone + iPad) SqueezeLite Squeezebox Server 7.6.2 (Debian 6.0) with plugins: CD Player, WaveInput by bpa IRBlaster by Gwendesign (Felix) Server Power Control by Gordon Harris Smart Mix by Michael Herger PowerSave by Jason Holtzapple Song Info, Song Lyrics by Erland Isaksson Just Covers by Tom Kalmijn WeatherTime by Martin Rehfeld Local Player, BBC iPlayer, SwitchPlayer by Triode Auto Dim Display, SaverSwitcher, ContextMenu by Peter Watkins. ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=100328
