Hello,
I've got problem with multicasting to many computers at once. I've got server with newest udp-sender (20071228) which is sending files from ext3 partition (with command ./udp-sender --pipe 'tar -B -S -cpf - -C /usr/share/systemimager/boot/i386/pjwstklenny .' --portbase 9006 --min-clients 2 --min-wait 15 --interface eth1 --max-bitrate 70M --mcast-all-addr 234.1.1.162 --ttl 10
and I'm trying to receive it with command:
./udp-receiver --portbase 9006 --nosync --ttl 10 --mcast-rdv-address 234.1.1.162 --pipe "tar -f - -x -vv -C /disk"
on client computer.
Problem is that, when I'm doing it one-by-one (I mean server-1 client) I get full speed - ~70MB/s, but when I'm trying to to this with >= 2 computers transfer drops to >0,5Mb/s. Why? I tried diffrent and the same subnet, I'm using 3com & cisco 3-layer switches (I also tried putting server and clients on the same switch - the same effect).
Please help, cause I've got >200 computers to clone ;)
Best regards
