Initrd - Cast-o-Matic issue with mount
by Greg Hasseler 31 Jul '07

31 Jul '07

My desired use of udpcast involves PXE booting machines. I am able to successfully PXE boot, and I am also able to successfully image the machines. However, I would like to further automate the process, which involves implementing a post-setup script. The easy way for me to achieve this (I have the script written) is to simply use the Cast-o-Matic tool (which I do like). However, I have noticed a discrepancy in the output of the initrd file from the Cast-o-Matic versus the "ready prepared" initrd image available for download. When using the ready made initrd, I am able to successfully mount the hard drive. Mounting the hard drive is required so that my post setup script can then make the necessary changes to key files. However, when using the Cast-o-Matic generated initrd, I am unable to mount the hard drive. I am given a mount command failed error. My desired behavior is that I would also be able to mount the hard drive with this initrd. What I would like to know is if the discrepancy can be fixed (only assuming that there is one--maybe mismatched versions?--I don't know), or if there is a way for me to make the "ready prepared" initrd work for my needs? To do this, I would need to inject two files. I realize that most initrd files are simply compressed with cpio and then gzipped. I see that this seems to be the case with the Cast-o-Matic initrds. However, I do not seem to be able to successfully decompress/extract the ready made one using the same technique. I apologize for my long windedness. The target operating system is Gentoo Linux. If any more information is required, please let me know and I will be more than pleased to provide it ASAP.

Thank you both, Jens and Michael. I was missing some dependencies as you both indicated. I was able to compile it today without a problem. What a coincidence that you replied Michael; I was actually updating the udpcast binaries in G4L (terrific project btw!) for testing.

Compiling from Source
by Jon Miller 26 Jul '07

26 Jul '07

I had a question about compiling udpcast from source. I am inexperienced with Linux, so I am probably doing something wrong. I downloaded udpcast-20070602.tar.gz as listed on the site ( http://udpcast.linux.lu/source.html). I followed the steps to extract the file to a folder and changed to that directory. However, when I typed the make command, it says "make: *** No targets specified and no makefile found. Stop.". This is under Ubuntu 6.10. I also tried "make --file=./Makefile.in" thinking that it might be what was needed but got a different error (CC@: Command not found & Error 127). Can you help me figure out what I am doing wrong? Thanks for the project! I am hoping to implement this at a university to replace Ghost. -Jonathan M

Question for UDPcast
by Markus Forster 16 Jul '07

16 Jul '07

Hi, i've got a question about UDP-Cast: How can i integrate an telnet server into an initrd for the PXE System? Maybe you have a tutorial to realize it? Or can you give me any tips to do that? I haven't found a forum on your website to ask someone about this, therefore i write this email. Thank you in advance.
