Is there something that I might be missing that would not be explained on the site to build a udpcast cd from my own kernel? I am using a RedHat 9 box and also have access to a Debian testing computer. I have tried everything I can think of and have read everything on the site. I tried using the floppy and putting the megaraid and scsi modules on a second floppy. But I can't find where to load the modules form the second floppy. When I choose the load other modules form the menu those are not listed, just all the net modules. All I really need is the same thing as the regular cd only with megaraid and raid 5 support in the kernel or available as modules. thanks -- Randy Reames Web Developer Midwest Energy OS X and Debian GNU/Linux ~ Mozilla Web browser Web Standards matter ~ www.webstandards.org/about www.reames.org ~(*)~ www.mwenergy.com

no init found
by Randy Reames 18 Dec '03

18 Dec '03

I was able to compile a kernel with support for the megaraid controller but then it kernel panics with no init found. I loop mounted the iso and got this: 2048 Dec 17 13:20 boot.catalog 1359 Dec 17 13:20 INITRD 9652 Dec 17 13:20 ISOLINUX.BIN 80 Dec 17 13:20 ISOLINUX.CFG 755417 Dec 17 09:43 LINUX the INITRD is a lot smaller here than on the cd image I downloaded. Is there something I am missing to include in the makeImage? I am doing the # ./makeImage -k /usr/src/linux-2.4.21/arch/i386/boot/bzImage -c udpcast.iso Getting closer to cloning these servers.

udpcast-20030803 weird error/transfer abort
by Tien-Duc Nguyen 16 Dec '03

Hello udpcast users! When trying to multicast data to 7 machines, very often transfers abort with this error message: udp-receiver: receivedata.c:419: checkSliceComplete: Assertion `0' failed. /bin/tar: Unexpected EOF in archive /bin/tar: Unexpected EOF in archive /bin/tar: Error is not recoverable: exiting now Here's my environment: Operating System is RedHat 8 with kernel 2.4.20-24.8smp Linksys EG0008 Gigabyte Switch (supports 10/100 also), no config utility by web or serial so I guess it's unmanaged All the nodes have Intel pro/1000 network cards are in 1000Mbps full-duplex as shown by the boot messages, except one node which has a 3Com PCI 3c905C Tornado in 100Mbps full-duplex (set with proper args to the module) I have tried running udpcast-sender in full-duplex and half-duplex. Has anyone in this list encountered this error before? Tien Duc

udpcast scsi
by Randy Reames 15 Dec '03

15 Dec '03

I have used udpcast to clone ide boxes. But I cannot get it to recognize the scsi drives (raid 5) on a couple servers. It looks like the scsi modules are there but are not being loaded at the cd boot. How can I clone /dev/sda on these servers?

Re: [Udpcast] pxe undi network driver

Thank you again for the quick response. I created the /chroot-test dir and did like you said, using chroot to run hdparm. It looks like my distro also requires /lib/ld-linux.so.2 and /lib/libc.so.6. Once those are in place in /chroot-test/lib/ I can load hdparm. I used ldd and ls -ls to find the files that the links pointed to. # ldd /sbin/hdparm libc.so.6 => /lib/libc.so.6 (0x40020000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) # ls -ld /lib/ld-linux.so.2 lrwxrwxrwx 1 root root 11 2003-11-13 15:12 /lib/ld-linux.so.2 -> ld-2.3.2.so # ls -ld /lib/libc.so.6 -rwxr-xr-x 1 root root 1491599 2003-03-13 17:33 /lib/libc.so.6 Then I do a ./makeImage -k /usr/src/linux-2.4.22/arch/i386/boot/bzImage -c /tftpboot/udpcast/images/udpcd.img -i /tftpboot/udpcast/initrd --bzip -m bcm5700 --merge /bin/hdparm=/sbin/hdparm /lib/ld-linux.so.2=/lib/ld-2.3.2.so /lib/libc.so.6=/lib/libc.so.6 I load the image up and I do a /bin/hdparm. "/bin/hdparm: No such file or directory" cd /bin ls -l |grep hdparm -rwxr-xr-x 1 0 0 47976 Thu Jan 1 00:00:00 1970 Thu Jan 1 00:00:00 1970 hdparm cd /lib ls -a all it shows is the modules dir I double checked the syntax for the library names, and they're correct. Just to try and troubleshoot, I tried merging /lib/ls-2.3.2.so from my pc to /lib/ld-linux.so.2 in my initrd image. ./makeImage -k /usr/src/linux-2.4.22/arch/i386/boot/bzImage -c /tftpboot/udpcast/images/udpcd.img -i /tftpboot/udpcast/initrd --bzip -m bcm5700 --merge /lib/ld-linux.so.2=/lib/ld-2.3.2.so Then I cd to /lib and do an ls, and the only thing that is there is the modules dir again. I tried one more thing. I tried merging /lib/ls-2.3.2.so from my pc to the root dir /ld-linux.so.2 in my initrd image. ./makeImage -k /usr/src/linux-2.4.22/arch/i386/boot/bzImage -c /tftpboot/udpcast/images/udpcd.img -i /tftpboot/udpcast/initrd --bzip -m bcm5700 --merge /ld-linux.so.2=/lib/ld-2.3.2.so This time I boot and do an ls, and I see ld-linux.so.2. I wonder why it copied this time and not the other times??

Re: [Udpcast] pxe undi network driver
by Eric Becker 05 Dec '03

Ahhh...I see. Thank you for the reply. I have gotten a custom compiled kernel (with my bcm5700 net drivers) to work using the makeImage utility. I can successfully create floppy and cdrom utilites that work with my hardware. I can also boot using PXE with my custom kernel. However, I would like to include hdparm in initrd. I'm using the following syntax when running makeImage "./makeImage -k /usr/src/linux-2.4.22/arch/i386/boot/bzImage -c /tftpboot/udpcast/images/udpcd.img -i /tftpboot/udpcast/initrd --bzip -m bcm5700 --merge /bin/hdparm=/sbin/hdparm". I boot up my PXE client and go to the console and type /sbin/hdparm, but I get "no such file or directory. I can see the file if I do an ls, but I can't execute it. Any ideas? >>> Stefan Jaeckel <jaeckel(a)wiwi.uni-halle.de> 12/04/03 01:51 AM >>> hi, the network driver has nothing to do with UNDI, after pxe (kernel and initrd loading) you have got a normal linux booting process with a ramdisk. Be shure, that you have copied the driver module from /lib/modules/<your kernel>/kernel/drivers/net/<your nic>.o onto your initrd. If you can boot the "master" system for the pxe-image from hd or cdrom, type "lsmod", to find out which network driver is loaded. It would be one of "/lib/modules/<your kernel>/kernel/drivers/net/<your nic>.o". You can also look into /var/log/messages or boot.msg on your pxe-system, to find an error message about the missing module. Or compile the network driver directly into a new kernel ("lspci -v" on the master system is also helpful). ciao Eric Becker schrieb: > > I'm able to load the pxe images for udpcast successfully on my network > clients using tftp and dhcp.

pxe undi network driver
by Eric Becker 04 Dec '03

04 Dec '03

I'm able to load the pxe images for udpcast successfully on my network clients using tftp and dhcp. However, I'm running into a problem loading a network driver. Is there any undi driver built into the pxe image or do I need to compile my own kernel with support for one?
