A bug in udpcast doc ?
by Steven Shiau 17 Feb '07

17 Feb '07

Hi, I read the doc cmd.html, and did some test about --broadcast, IMHO, I think the following doc in cmd.html should be fixed: ---------------------------- Networking options The following networking options should be supplied both on the sender and the receivers: ... --broadcast ... This option should only be supplied on the sender. ---------------------------- udp-receiver --boradcast udp-receiver: unrecognized option `--boradcast' udp-receiver [--file file] [--pipe pipe] [--portbase portbase] [--interface net-interface] [--log file] [--ttl time-to-live] [--mcast-rdv-addr mcast-rdv-address] [--rcvbuf buf] [--nokbd] [--exit-wait milliseconds] [--nosync] [--license] --broadcast should only be used in udp-sender, Not with udp-receiver. Therefore --braodcast should be moved to the session "The following networking options should be supplied only on the sender:" Thanks.

Re: [Udpcast] Image Server

Hi again, I used boot cd for updcast. Yes, the new hdd in exactly the same size and have the same layout becouse i used dd to get the same partition tables, and after that formated them. But for now i only want to backup the boot partition, not the entirely hdd. And i know the problem is on the backup method or file, becouse i have a ghost image from the partiton and restored it without any problem, and everything is fine. If use the file make with udpcast, i get error checking filesystem ( chkdsk ). I'm don't blaming udpcast, becouse i know it's me the one don't know how to do it. Maybe the correct question is: is it possible to backup a partition, using updcast, through a network and strore it on a file server? For your answears i supose it is posible, wich steps you followed? or which option you use to backup to a file and restore from a file? Thanks!! On 2/15/07, Michael D.

Hi, I'm trying to make some kind of imageserver. I backed up my windows 2000 boot partition to an image file on the server. I restore it, without problems..everything is ok. But if i change hdd, o if destroy partition and create a new one ( same size, same place ), i can restore the image but windows won't boot. when i check filesystem y get some errors ( of course they weren't when i backup the partition ). I even fixboot and mbr with the same result. Anyone can helpme with some tip? Thanks!!

by Haiwei Sun 13 Feb '07

13 Feb '07

Dear Sir: I am testing UDP-sender.exe and UDP-receiver.exe under WinXP with following commands. But a error (marked by red color) happens after the server transfers data once. Under linux, I have never met this problem. I am wonder if there is a bug? UDP-sender: C:\Documents and Settings\hwsun.PSL-AD\Desktop\UDPCast-run>udp-sender -f test.tx t -P 5004 -M 239.1.1.1 --daemon-mode --nokbd --min-receivers 1 Udp-sender 2007-02-05 Using mcast address 234.81.112.185 UDP sender for test.txt at 10.81.112.185 on Intel(R) PRO/100 VE Network Connecti on - Packet Scheduler Miniport (00-00-e2-5b-c7-66) Broadcasting control to 239.1.1.1 New connection from 10.81.112.185 (#0) 00000009 Starting transfer: 00000009 bytes= 1 230 re-xmits=0000000 ( 0.0%) slice=0000 1 230 - 0 Transfer complete. Disconnecting #0 (10.81.112.185) bind socket to 10.81.112.185:5005 (Bad file descriptor) <------------ why???

Exiting udp-receiver or reboot machine after a certain amount of time without transfer activity
by Jens Breuer 09 Feb '07

09 Feb '07

Hello, I am curious whether there is an commandline option which could instruct udp-receiver to exit after a certain amount of time without any udp-sender activity or generally when the transfer process doesn't start. At least I could not find anything in the documents. We use udpcast together with PXE-boot and sometimes some machines are simply not responding to the sender (why is yet unclear). After manually restarting the machines it is usually the case that the machines to be imaged are responding again and everything is well. Unfortunately it could be the case that there are machines to be imaged which are placed in locked rooms and so it is impossible to restart them manually. Regards Jens

Hi All, Have Latitude D620s - I can't make UDPcast bootdisks that support the Broadcom 57xx Gigabit network card and Intel SATA drivers. I can't find documentation to add these drivers manually. Any ideas? Thanks, Alex

cast-o-matic initrd modules.info does not include all modules?
by Frederik 07 Feb '07

07 Feb '07

I'm trying to create an initrd for udpcast with cast-o-matic. In the first screen, I only chose sky2 gigagabit ethernet driver and the ahci and piix SATA drivers. These files are actually present in the generated initrd, but it seems the file /lib/modules/modules.info does not include any SATA drivers. Could somebody check this please? -- Frederik
