I didn't know of any and was wondering if | anyone out there in netland knew of any. If not, I guess I will have | to write something myself. I would appreciate any infomation about | programs or algorithms that do file broadcasting. It must use a broadcast, | not a copy to one machine then copy to another method (i.e. UDP), and | if a machine is up it must reliably send the file. +--------------- Using the multicast features of the XTP protocol, you could do what you want with something like the following: for i in $MACHINELIST do # start each receiver listening rsh $i 'txtp -r -s -M | tar xf - &' done # now multicast the file txtp -t -s -M
