Hi, I apologize if this is a stupid question - actually, I rather hope it is because if I've just missed something somewhere in the documentation then this should be easy to sort out. I've got about 30 work stations here that are used by conferences a dozen or so times a year. Each time they come in they manage to make a mess of them in one way or another, so each workstation gets re-imaged once they've gone away. Currently, we do this with a little linux partition with G4L on it and a little tweaking of the Windows NT boot loader. (Basically, run batch file in windows - machine goes down, linux comes up, script runs, disk image.gz is pulled from FTP server and written to the windows partition, machine goes down, windows comes up, job'sagood'un) This works rather nicely, but it takes a painfully long time as the FTP server struggles under the load of 30 connections. UDP-cast looks perfect for solving this problem, but I can't seem to make it work. This is the command I've got: (from the FTP server - windows 2003 machine) Udp-sender.exe -file c:\bootfiles\image.gz (from the client machines linux command line) Udp-receiver -pipe "gzip -dc" -file /dev/sda1 The network infrastructure is very simple. All the machines involved are in the same subnet 129.67.50.xx (in fact they're all on the same switch to try and keep this as fast as possible) The UDP sender starts to run and awaits connections, but never seems to get any. The UDP receivers sit and wait for a control connection from the server, but never get any either. What am I doing wrong?
