I am working on a tool using udpcast that works kinda like ssh .. but allows one to 'cast' to multiple hosts. I cheat and use 7zip to do the data reduction. THis uses Windows XP and/or 7 .. and you have to have something on the windows side to tell it to start listening...

For now you can run this on the receivers:

udp-receiver.exe --nokbd | 7z x -si -ttar -y -a{targetdir}

and then this on the sender

7za a -ttar -so foo /sourcedir -r | udp-sender --full-duplex

and that will handle the work for you. Works well and is well tested.

PS > you have to use -ttar because 7z doesn't appear well supported for streaming .. particularly between different OS's

Hi everyone,

I tried the udpcast, one problem is that the tool copy ALL the disk, even the empty space....

for optimize the speed, is there a option to allow the copy of only the data on disk, and not all the disk ......

I have a Windows 7 with about 9go of data on a 250go disk, and wants to copy only this 9go.

thank you for your help !
