If you already have another computer, why don't you just send the wakeup from that computer anyway?

Well its a router thing. I used to route the packet (from the net) via an intel Wireless router connected to a 10Mb hub. This all worked fine for ages. Then I replaced these 2 with a shiny new 54Mb SMC router with a 4 port 100Mbps switch. It took me ages to work out why it became unreliable but it seems that the switch "forgets" how to send directed UDP packets to the server's IP after about 10 mins of it being standbyed (flushes ARP cache???) . However, it still responded to broadcast packets. I cannot send broadcast packets from the net via the router and here we are. The empeg is always on, and thanks to Mark's recent additions to hijack, namely authentication, I can open up the empeg to the net and make a web interface... maybe.

If I can bind the script to a button then I can send the /?bottonno from my page I think. This would give me the perfect solution.

I have also piped a netcat listener to another instance of netcat which broadcasts which gives me the same functionality as before my new hardware broke everything.
