[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

Troubles with busybox v1.5.0 (2007-03-28 14:34:43)
by Stephane Boireau (Animateur TICE Bernay/Pont-Audemer) 02 Jun '07

Hi, It seems, a trouble happens using busybox v1.5.0 (2007-03-28 14:34:43). I build an iso using: # udpcast-20070323-1.i586.rpm # udpcast-mkimage-20070328-1.i586.rpm # kernel-udpcast-2.6.20.4-1.i586.rpm And I get strange things: # date Fri May 4 07:50:34 UTC 2007 # That's OK. But: # date > /tmp/date.txt # cat /tmp/date.txt # # A=`echo world` # echo $A world # That's OK. But: # A=`date` # echo $A # No completion working. Is it possible to correct this? Thanks! -- Stephane Boireau Animateur TICE Bernay/Pont-Audemer

Re: [Udpcast] GZip files only

Dear Alain, Thanks for your clarification. May be the function file_gzip_uncompress() at received side can help to support it.

GZip files only
by Haiwei Sun 10 May '07

10 May '07

Hi All, There is a parameter named "-z:int" at sender side which means: Encode content [0=no, 1=ZLib FDT, 2=Zlib FDT and GZip files, 3=Pad files], default=0 However, if somebody sends me uncompressed FDT along with GZip files. Can receiver still work? Thanks in advance, Best Regards, Mr. Haiwei Sun R&D Engineer Panasonic Singapore Laboratories Pte Ltd Singapore

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

UDP Multicast & Internet problem
by AB Benzaquin 10 May '07

10 May '07

Hi, I have a small switched network of 25 machines, with a Linux box sharing a PPPoE connection. I'm using udpcast to transfer files to several machines at once using multicast. It works great, however, the other machines can't access internet during the transfer. I've googled around and seen several posts related to multicast and internet problems, tough not solutions. Perhaps you can help me. Thanks in advance.

Intel Macbook
by Humberto J. Varela 04 May '07

04 May '07

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?
