I have problems restoring image with Clonezilla which uses udpcast. Since it seems that it's problem in udpcast I'm sending description of the problem here.
Whole discussion you can find here https://sourceforge.net/mailarchive/forum.php?thread_name=49A3C8C9.1080603%4... or here http://tinyurl.com/bk5m9p
And here is explanation of problem and messages that I receive on CLI and in log files.
I create image of MS Win XP and I save it to server. Then I boot clients with PXE and they start Clonezilla. After that Clonezilla server should start sending multicast (or brodcast, whichever I choose in configuration) data.
3:14 minutes after that I get this message on CLI
**** apt-cache search/opt/drbl/sbin/ocs-functions: line 3537: 27660 Exit 141 ( for img in $imagedir/$target_d/$img_file_prefix; do cat $img; done ) 27662 Floating point exception| $udpcast_send_cmd 2> $udpcast_stderr ****
And in /var/log/messages I have
**** Feb 27 08:26:37 server udpcast[27662]: New connection from 192.168.1.104 (#0) Feb 27 08:26:37 server udpcast[27662]: first connection: min wait[0] secs - max wait[0] - min clients[4] Feb 27 08:26:47 server udpcast[27662]: New connection from 192.168.1.103 (#1) Feb 27 08:27:10 server udpcast[27662]: New connection from 192.168.1.105 (#2) Feb 27 08:27:20 server udpcast[27662]: New connection from 192.168.1.106 (#3) Feb 27 08:27:22 server udpcast[27662]: min receivers[4] reached: starting Feb 27 08:27:22 server udpcast[27662]: Starting transfer: file[] pipe[] port[2232] if[eth1] participants[4] Feb 27 08:30:36 server udpcast[27662]: dropped client #0 because of timeout Feb 27 08:30:36 server udpcast[27662]: Disconnecting #0 (192.168.1.104) Feb 27 08:30:36 server udpcast[27662]: dropped client #1 because of timeout Feb 27 08:30:36 server udpcast[27662]: Disconnecting #1 (192.168.1.103) Feb 27 08:30:36 server udpcast[27662]: dropped client #2 because of timeout Feb 27 08:30:36 server udpcast[27662]: Disconnecting #2 (192.168.1.105) Feb 27 08:30:36 server udpcast[27662]: dropped client #3 because of timeout Feb 27 08:30:36 server udpcast[27662]: Disconnecting #3 (192.168.1.106) ****
I have tried to restore two images and they both end the same way (3:14 min and same message). And I can restore that image with unicast, so it's not image problem.
I have tried both multicast and brodcast method, and non of them works, so I guess it's not switch issue.
All clients and server are connected on one switch.
Please confirm me that I'm having problems with unicast. Please help me to troubleshoot this problem.
Best regards,
P.S. I'm using Ubuntu 8.10 server and udpcast version is 20081213

Does the problem also happen with udpcast alone?
Does it still happen with current versions of udpcast?

Hi Alain!
I haven't tried to use udpcast alone. To tell you the true I'm not even sure how to do that.
Can you confirm that this is udpcast problem?
Best regards,

Hi Alain!

It's easy. On the sender, you say
udp-sender -f myfile
and on the receiver:
udp-receiver -f myfile
myfile may also be a device (such as /dev/sda1)
You can also use one of the bootimage from http://udpcast.linux.lu , which boots into a menu system that starts udpcast with the appropriate parameters for cloning disks.
Can you confirm that this is udpcast problem?
Unfortunately I can't confirm it at this point in time, without any more information.
