throttle output of udp-cast
by David Crider 23 Sep '08

23 Sep '08

Is it possible to do dynamically throttled UPDcast transmission? We need to throttle the data flow to a Logic Innovations IP encapsulator (with LI's documentation attached with their permission). The udpcast mutlticast address is considered a single route to the IPE. The IPE sends out flow-control messages (described in document) that shows how many bytes are available for traffic for each route every 100 milliseconds in a multicastand comes from a user specified multicast of its own. Attached is the LI document, again with the manufactures permission. Also, you can contact Theo Aukerman, taukerman(a)logici.com for any additional info. I'm asking these questions because IF this is possible, then this would be an almost complete framework for an open source Data-casting network, and can be used for over the air data-broadcasting from any DTV transmitter or any other system with null packets. I currently work as an engineer for a TV station that does data transmission, but would like to move to an open source model.

Include ntfsresize into initrd
by Jeff Michels 03 Apr '08

03 Apr '08

Hello, I would like to include ntfsresize into an initrd created by cast-o-matic. I compiled ntfsresize statically and uploaded the application to be included in the initrd. I'm pretty sure this is a busybox issue. ntfsresize appears in the initrd but I cannot execute it. I am not very familiar with busybox so any help would be appreciated. Thank you in advance.

Intel 82566 NIC driver

Are there plans to place a driver for the new Intel 82566 DM -2 GB NIC on the list of NIC drivers for making a UDPCast CD. The Dell 755 has the above named NIC plus a DH-16W1S SATA CD drive and a SATA HD. Thanks, Chris Albertsen Chris_albertsen(a)abss.k12.nc.us

Eject CD...
by Stephane 18 Jan '08

18 Jan '08

Hi, Eject CD: =================== #( cd /proc/ide ; for i in hd? ; do if fgrep -q cdrom $i/media ; then eject /dev/$i ; echo ejecting /dev/$i ; fi ; done) =================== doesn't work anymore because proc-ide support isn't in the kernel config. I do this: =================== modprobe ide-cd #periph_cd=`fgrep -l cdrom /sys/block/*/device/media | sed 's/\/sys\/block\/$.*$\/device\/media/\1/'` periph_cd=`fgrep -l cdrom /sys/block/*/device/media | cut -d"/" -f4` =================== But, if I put it in predialog, it doesn't work because /dev/hdc doesn't exist at this time. /dev/hdc exists after beginning of dialog. Is it possible to automatically eject CD before dialog end? Available variables are: =================== my $postscript; my $prescript; my $predialogscript; =================== but I think $prescript is run after dialog, am I wrong? Regards. -- Stephane

Action on success or failure
by Stephane 18 Jan '08

Hi, Cast-o-matic allows rebooting on success. I suppose it's /post job: ======================== #!/bin/sh if [ $1 = 0 ] ; then exec reboot -f; else echo "Error. Not rebooting";fi ======================== But I'm not sure I understand $1 Does it mean /post is launched with $? udp-receiver return as first parameter ($1)? Regards. -- Stephane

predialog doesn't run? eject trouble!
by Stephane 07 Jan '08

07 Jan '08

Hi, I get: * Udpcast command line version: udpcast-20070602-1.i586.rpm * Udpcast boot disk generator: udpcast-mkimage-20071228-1.i586.rpm * Udpcast Linux kernel for use with boot disk generator: kernel-udpcast-2.6.23.12-1.i586.rpm and build DEB packages using alien (DEB version at http://udpcast.linux.lu/source.html require libc6 higher than I have on etch). I build an image including my scripts. And predialog doesn't run. (it worked in previous version) If I launch my predialog manually (ALT+F2,...), it works. My predialog is used to get udpcast parameters from boot and generate /udpcfg.txt before udpc_dialog is launched. My predialog was: =========================== #!/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 =========================== But there is an error: When launching cd /proc/ide I see /proc/ide: bad directory And script stops. Solution: If I comment line used to eject CD, it is OK. My script runs. Maybe it would be possible to do something using /proc/sys/dev/cdrom/info or /proc/sys/dev/cdrom/autoeject # grep "drive name" /proc/sys/dev/cdrom/info drive name: hdc # But # grep "drive name" /proc/sys/dev/cdrom/info | sed -e "s/ //g" # Troubles with redirections? I would like to do something like: # grep "drive name" /proc/sys/dev/cdrom/info | tr "\t" " " | sed -e "s/ //g" | cut -d ":" -f2 Regards. -- Stephane

jmicron driver
by john 05 Jan '08

05 Jan '08

Hello I'd like to pre-configure the boot disk menu but there doesn't seem to be the jmicron ata module available. Is there some way I can add this? It seems to be available (works ok) when I download the basic ISO without pre-configuring the boot menu. John =======
