Hi,
I have been working on getting multicast systemimager image broadcasts to work, but I am having a hard time.
Is it just me (am I doing something wrong?) or does udp-sender completely ignore the wait and client parameters?
Udp-sender doesn't wait at all for a minimum number of clients, after the first connection, it immediately starts the multicast to the first client.
On the server:
# udp-sender --pipe 'tar -B -S -cpf - -C /home/test/sara/ramon/testdir . ' --portbase 12345 --min-clients 20 --max-wait 1800 --min-wait 600 --fec 8x8/128 --interface eth0 --max-bitrate 20M --full-duplex --nopointopoint --nokbd stripes=8 redund=8 stripesize=128 Udp-sender 2004-02-22 Using mcast address 234.168.44.1 Compressed UDP sender for (stdin) at 10.168.44.1 on eth0 Broadcasting control to 10.168.44.255 New connection from 10.168.44.5 (#0) 00000019 Starting transfer: 00000019 bytes= 11 929 600 re-xmits=000000 ( 0.0%) slice=1024 73 709 551 615 - 0 Transfer complete. Disconnecting #0 (10.168.44.5)
On the client:
# udp-receiver --interface eth0 --portbase 12345 --nokbd --nosync --file ./bla.tar Udp-receiver 2004-02-22 UDP receiver for ./bla.tar at 10.168.44.5 on eth0 received message, cap=00000019 Connected as #0 to 10.168.44.1 Listening to multicast on 234.168.44.1 bytes= 11 929 600 ( 15.91 Mbps) 11 929 600 Transfer complete. ramon@u5:~/1.udptest$
Now there is no timestamps, but the udp-sender starts the multicast in about 2 seconds after the connect from the client. But the sender does not have 20 clients connected, and it didn't wait 10 minutes at all (I kind of overdid the values here, but with lower values it doesn't work either).
Am I missing something?
Kind regards,
Ramon Bastiaans.
Are you using flamethrower to do this?
