It only appears with statically compiled busyboxes and has been reported to the busybox dev team. But somehow, I've got the feeling that the busybox team not really cares about static compilation. In the meantime, I've implemented a local fix in udpcast-20070602 (explicitly fflush'ing stdout just before exit) Regards, Alain From alain at knaff.lu Sat Jun 2 14:08:40 2007 From: alain at knaff.lu (Alain Knaff) Date: Sat, 02 Jun 2007 14:08:40 +0200 Subject: [Udpcast] [PATCH] fixes parallel make & make DESTDIR=/tmp/xxx install In-Reply-To: <200704070852.07758.dragonheart@gentoo.org> References: <200704070852.07758.dragonheart@gentoo.org> Message-ID: <46615DC8.4000601@knaff.lu> Daniel Black wrote: > 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.

Thanks for the note Alain From Alex.Richards at saultcollege.ca Mon Jun 11 19:30:23 2007 From: Alex.Richards at saultcollege.ca (Alex Richards) Date: Mon, 11 Jun 2007 13:30:23 -0400 Subject: [Udpcast] Help needed... Message-ID: Hi; Hopefully you can shed some light on the situation I am encountering. I have a class set of 30 Dell Optiplex 745 workstations - and the drivers on the Web Configurator (primarily the tg3 driver) did not work with the Broadcom NetXtreme Gigabit network adapter in these workstations. So I built a new set of disks using a Feisty Fawn live cd and its Kernel to get the appropriate driver support. I am now able to get udpcast working to send a sysprepped windows xp pro image, ntfs - 80gb sata drive(ata-piix). I am now having the issue where machines are randomly failing with the newly casted image. I've been using lzop compression and have received a few errors on the sender - but the my main concern is that random machines get a disk read error (obviously wont boot) and some get NTLDR Missing error messages. This is very odd as it isn't always the same machines that get this error after a cast. I can restore a ghost image to those machines individually - they then initialize just fine. I've also tried to create disks using the Fedora Core 7 live cd with the same results. I am attaching a the very rough documentation I made as a reminder to myself on how I create the udpcast disks. Udpcast is great and works flawlessly on my older Dell labs here in the college! The issue has stumped me for about a month as I've tried different techniques on and off. Your insight is greatly appreciated!!

Well that's okay and udpcast is fantastic but if I could clone 20 pcs also with 500 Mbit/s it would great. Does anyone knows the reason for the reduced transferrate - whichever could be the bottleneck?

You either have to clone the entire hard disk, or just one partition. Cloning a selected subset is not yet supported.

Message-ID: <8E18F51F62CF334D8052662DC4EEA0313B54D1@RHEA.pedagogie.euroschool.lu> Hi everybody, I have a problem with the images castomatic for PXE. When I download the PXE image already prepared on the site, there is no problem but if I want to create my own preconfigured image with castomatic, the image will load but an error occures and we can see the following error message : File "/lib/modules/2.6.21.3udpcast/modules.pcimap" not found (No such file or directory) I tried 3 images : - Preconfigured for a Dell optiplex 740 (NIC => tg3, Sata => sata_nv) - Preconfigured for a Dell optiplex GX620 (NIC => tg3, Sata => ata_piix) - Preconfigured (NIC => Autodetected, Sata =>Autodetected) Please note that my DHCP server is on a Windows Server and that my TFTP server is on another Windows Server. I don't think the problem come from my infrastructure. The problem should come during the creation of the image by castomatic. Is someone already encounter this issue ?

Everything is in line now, could you try it again?

I have been using udpcast (version 2006-09-15) successfully until last week when I decided to upgrade. I first tried 2007-06-02, but that didn't work. So I tried 2007-03-26 and that failed in the same way. When I use either of these newer images I see this message on the receiver: ... sending go signal lzop: : block size too small -- recompile lzop bytes= 848 848 (43.00 Mbps) and then the transfer stops. The program doesn't end, but the sender just continues to timeout. Any help would be appreciated. It must have happened between Sept, 2006 and March, 2007. I am using the prebuilt images from the CD- ROM, booted via PXE, as my receiver. My sender is Mac OS 10.4 PowerPC and I tried the Sept '06 and most recent versions of the program. I tried lzop 1.0 and lzop 1.02rc2, both of which work with the older receiver.

The bug has been there for ages, but as it only occurs on certain inputs (and never with archives generated with udpcast's busybox itself), it went unnoticed for so long. This is fixed now (version 20070622) (However, due to the nature of the problem, the new version *may* now produce archives which are unusable by the old version) Regards, Alain From devin at freeshell.org Mon Jun 25 21:08:05 2007 From: devin at freeshell.org (Devin Bayer) Date: Mon, 25 Jun 2007 19:08:05 +0000 Subject: [Udpcast] [PATCH] Mac OS X Fixes Message-ID: This patch applies to 20070602 and has a few fixes needed for OS X 10.4. * removes 3 harmless warnings in fifo.c, log.c, statistics.c, and util.c * drops the fatal error when getting the broadcast address fails for an interface, since this is normal for the loopback, which is checked before the ethernet. This causes udpcast to always die unless the -- interface option is used. * use the alternative IP_MULTICAST_IF method, same as for Cygwin. The comment in the code made it sound like Cygwin was out of the norm, but it's Linux that's at ends with OpenBSD, Apple OS X, Solaris, Cygwin, etc...
