Using MAC addresses from DHCP to send wake on lan packets to all machines.

We have recently migrated a linux dhcp server to windows 2003.

The Linux system had a quick script that read mac addresses from the dhcp leases file, and I could then send a wake on lan packet to all the pc`s dhcp had "seen".

Since moving to windows I am struggling to get hold of the mac addresses from dhcp, or a utility to send the WOL Packets.

Is this possible? If so how?

Thanks

OK, that really helps getting the data out of dhcp. The next stage it converting this to a format useable with a wol package.

Previously this was using grep on linux, which of course doesn`t exist natively in windows.

Hitting google for stage  two, but any suggestions greatly recieved.

Thanks

Check out this link

Click on the SFU for UNIX commands for windows.  I haven't used it so I can't vouch for it.

Gary,

Yes I have seen some of this, and the cygwin equivelents. Actually I am stuck trying to find a win32 command line program to send wake on lan packets!

Tried several last night, all with no response from the PC`s. Didn`t think windows firewall would stop them being transmitted?

Going to try a manual cut copy paste across to the old linux server and confirm WOL is ok from there.

Here's a good tutorial on WOL.

Here's a link to a WOL client.

There's supposed to be a program from AMD that's free, but I couldn't find it on their site.

Cheers,
