Darwin build fixes patch
by Devin Bayer 18 Apr '07

Hello. Thanks for developing udpcast. It almost compiles on my mac. But I have to make a few small changes. 1.) the linker doesn't support the -Wl,-warn-common option 2.) what is malloc.h? It isn't needed. 3.) struct ifreq is variable size, so we must use _SIZEOF_ADDR_IFREQ (), not pointer arithemetic 4.) some endian issues Thanks, Devin Bayer

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

optiplex 745 and keyboard problems
by Chad Brogan 30 Jan '07

30 Jan '07

I've done some googling and found a few posts which seemed to indicate that udpcast shouldn't have problems working with a usb keyboard. Nonetheless, when I boot a pc from the cd or pxe, the keyboard does not work. Where should I start in troubleshooting this problem? I am very much a linux noob, but if someone can get me started, I believe I can stumble my way through it. Thanks. Chad

udpcparam=autostart 12
by Stephane 16 Oct '06

Hi, I build a script to get parameters from isolinux boot and rewrite udpcfg.txt I can put only one kernel and one initrd on my multiboot-cd and preconfigure choices in isolinux.cfg See udpcfg_txt.sh It works fine. My predialog contains: ================= #!/bin/sh modprobe ide-cd /bin/udpc_dialog init ( cd /proc/ide ; for i in hd? ; do if fgrep -q cdrom $i/media ; then eject /dev/$i ; echo ejecting /dev/$i ; fi ; done) sh /bin/udpcfg_txt.sh ================= And I buid image with: ================= /usr/lib/udpcast/makeImage_2 -k /usr/lib/udpcast/kernel/vmlinuz-2.6.17.13udpcast --fullbox --prescript /usr/lib/udpcast/perso_bin/noblank --predialog /usr/lib/udpcast/perso_bin/predialog --postscript /usr/lib/udpcast/perso_bin/date_fin.sh -c udpfr_20061011b.img -C fr.conf ================= makeImage_2 is makeImage modified to add a few scripts including udpcfg_txt.sh I would like to know the way I could send '--autostart 5' from isolinux.cfg so I've got a not complete keyboard (fr.ktl) during isolinux. I do a little transformation to use . instead of - and ? instead of space. My isolinux.cfg contains: ======================== label u1 kernel linux/udpcast/vmlu26 append initrd=linux/udpcast/udprd root=01:00 persoparams=oui lang=FR kbmap=FR dhcp=yes compr=lzop port=9002 umode=snd label u2 kernel linux/udpcast/vmlu26 append initrd=linux/udpcast/udprd root=01:00 persoparams=oui lang=FR kbmap=FR dhcp=yes compr=lzop port=9002 umode=rcv ======================== I send: u1 netmodule=AUTO enableDiskmodule=no disk=/dev/hda udpcparam=..autostart?1 But I get this message: Extra argument "..autostart?1" ignored Udp-sender 2006-09-15 Using mcast adress... It seems, udpcparam aren't read from /udpcfg.txt How could I make it work? Thank you very much! -- Stéphane.

Has anyone managed to solve the problem of running udpcast on netbsd? It still tries to bind to an ip address of 6.4.6.x. Any suggestions? Regards, Steve

Problems with SATA
by MAAS Jean-Paul 05 Oct '06

05 Oct '06

Hi there everyone, I am using UDPcast for quite some time with a huge success in our School. However as of today, as I tried to clone my first SATA Disk on an FSC Esprimo, suddenly nothing works as I was used to. On the sender it indicates that I have an ata_piix SCSI ... driver. When I start the transfer, after 2 or 3 second I'll always get an error message on my receiver indicating "Not enough space". This seems quite impossible as I am copying a 40 GByte SATA (even if uncompressed) to a 250 GByte image storage HD which is about 5% used. Does anyone have a clue what my problem could be and how I could solve it. I have 30 machines to deploy in the quickest ossible way.
