Re: Remote Wake On Lan

I used to use WOL a lot on my own network. Solarwinds had quite a useful wol client which would then ping the target until it responded and then show you the machine is alive based on it starting to reply to pings.
Unfortunately I've never found a way to use WOL over the internet. Barry Zubel would be your best bet for that sort of information.
I need a new signature... i'm bored of the old one!

Re: Remote Wake On Lan

You would need to be able to get your router to send a wake-up packet to your PC.
See http://en.wikipedia.org/wiki/Wake-on-LAN#How_it_works
Maybe if you use a VPNHuh  Grin

Re: Remote Wake On Lan

The WOL packet is a specially crafted packed that is sent directly to a MAC address, rather than an IP address.
Unfortunately, this means that it can't be sent *directly* from a machine that's not on the same physical network.  However, if you are on the same physical network, there are a multitude of clients you can use, such as Fusion WOL

You need to configure your router with a NAT entry to forward the WOL 'magic packet' to the broadcast address of the LAN and, in particular, ensure that your router allows these 'directed broadcasts' to take place (as they are often disallowed by default in order to mitigate the potential for Denial-of-Service attacks).
Exact configuration obviously varies between routers but if yours happens to be a Cisco I can go through the specifics (it's only a couple of lines). I use this setup to allow remote (over the Internet) wake-up calls to be sent to servers that don't require 24/7 operation and, if I'm not at my usual remote client I'll use one of the online WOL packet senders such as http://www.depicus.com/wake%2Don%2Dlan/woli.aspx or http://www.remotewakeup.com/en/index.php.

Re: Remote Wake On Lan

I've discovered this free magic packet software for WOL, http://magicpacket.free.fr/
It seems to work well, I can even start up servers in the office when I'm dialled in on a VPN from home.
But I can't start my home PCs from the office as my router won't forward broadcast packets... unless someone has figured it out?  It's a Netgear DG834G

Re: Remote Wake On Lan

An update to my comment above:
I found this http://www.softword.it/freedg/ which is modified firmware for the DG834G v3 (which is the router I use), and I have loaded it and been using it for a couple of weeks now without problem.
If you want to wake up a computer remotely, you need to log in to the remote management of the router and select the Wake On LAN menu function.  It works well.
