[PATCH] fixes parallel make & make DESTDIR=/tmp/xxx install
by Daniel Black 02 Jun '07

02 Jun '07

make -j2 was failing because it started a make each for udp-receiver.1 and udp-sender.1. make DESTDIR=/tmp install was failing because the DESTDIR glue wasn't included. This is a standard part of autoconf and really helps when staging an install. Finally updated the gentoo packages associated with udpcast. http://packages.gentoo.org/packages/?category=net-misc;name=udpcast Keep up the great work, Cheers, -- Daniel Black <dragonheart(a)gentoo.org> Gentoo Foundation

Option --full-duplex
by Bruno Sampayo 10 May '07

10 May '07

Hi, I use the udpcast to send packages to many clients (udp-receiver). So my udp-receiver command line is: #udp-receiver --interface tap0 --nokbd --file U2.wmv Sender line is: #udp-sender --nopointopoint --interface tap0 --log logudp --nokbd --autostart 5 --file U2.wmv --full-duplex My udp-receiver has two kinds of connection: satellite links(low-latency) and local links (high-latency). So Could I use the option --fullduplex on udp-sender line? Thanks for any help, Bruno Sampayo -- Bruno Sampayo <bruno(a)samurai.com.br> Tel.: +55(011) 50973005 Engenharia Samurai Projetos Especiais

Intel Macbook

I am using two UDPCast cds (one sender, one receiver) to boot two Intel MacBooks in an attempt to clone one to the other. Ok, it didn't exactly work out 100% Turns out when I boot my custom UDPCast cds, the SATA Disk Driver and the Marvell Yukon Network chipset in the MacBook fight with each other for IRQ assignment, and UDPCast finally just turns one IRQ off. IRQ 10. Meanwhile, I attached an external Microsoft USB 105-Key Keyboard to a MacBook to see if UDPCast would work with it and it did. But the "repeated ghost keystrokes" are still happening that plague the internal MacBook keyboard. So it seems that UDPCast is not playing well with the USB Controller in the MacBooks. It's not the keyboard. It's the controller. If I can identify the USB controller manufacturer, I might be able to insert the proper USB kernel module at boottime and finally be able to type into UDPCast after it boots. That would make it easier to guide through the menu-driven system that UDPCast uses in default-mode. It would also let me read the system boot log with the limited shell that I call up. So as for my experiment, both MacBooks boot up into a state that is ready-to-go, but they can't see each other on the network. This is most likely due to the IRQ conflict I'm getting from the SATA drive vs. the Network chipset. Network ports do light up on the switch I'm using, but the two computers won't see each other. I've even tried two different switches in case one had some kind of internal circuit that blocked Multicast Packet Storms or something... Has anyone tried UDPCast cloning of Intel-based MacBooks?

Problem with SAS disk
by Lasaro Camargos 24 Apr '07

Hi all. I am trying to clone a powerconnect 1435 using udpcast, but can't get it to recognize my LSI Logic scsi disks with the cast-o-matic image. I tried to create an initrd from the Fedora I have installed on one of the nodes. The problem is then that not all modules are loaded at boot and, once I load then by hand and see the scsi disk on /proc, I have no idea of how to attach it at /dev Shouldn't this be automatic? Or should I mknod the device? I know this is not too specific to udpcast, but I've been out of the linux world for sometime and am a bit lost here. Google wasn't very helpful either. Thanks in advance for any suggestion/help/hint/pointer. lasaro

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
