You store an image of a complete system via ghost, but you clone all machines via udpcast? My problem is, that i'll get the next days 40 blades wich i have to install and udpcast seems to be the best way. Perhaps i'll install one blade and clone the other machines from this one. But i fearing the controller in this machine. I read there is a Pear4/im raid controller included and as i saw, this modul is not yet included in the udpcast version :-( > > > On 12 Dec 2005 at 13:07, Thomas Kuehling wrote: > > Subject: Re: [Udpcast] Problems with udpcast in combination with a fileserver > From: Thomas Kuehling <thomas.kuehling(a)mapsolute.com> > To: D Teed <dteed(a)artistic.ca> > Organization: Mapsolute GmbH > Date sent: Mon, 12 Dec 2005 13:07:05 +0100 > Copies to: udpcast(a)udpcast.linux.lu > Send reply to: thomas.kuehling(a)mapsolute.com > <mailto:udpcast-request@udpcast.linux.lu?subject=unsubscribe> > <mailto:udpcast-request@udpcast.linux.lu?subject=subscribe> > > > Hi Teed, > > > > Am Montag, den 12.12.2005, 07:51 -0400 schrieb D Teed: > > > Are the disk geometries the same on the master and target notebooks? > > > Is lilo or grub or other used as the boot loader? > > > > not really.

Problems with udpcast in combination with a fileserver

by Thomas Kuehling

Dear all, i've got a strange problem with udpcast. If i store the files on an ext3-partition on a fileserver via udp-reciever -f foo.image and clone it on the other notebook, i am not able to boot the new system on it. When i look on the hdd, i see the several partitions, but no partition types. What's my fault? I am getting more and more confused. Please help me.

It could be an ordinary dependancy or lib you don't have. Usually the last 6 to 10 lines from a make error tell the tale of what went wrong. I've built udpcast on Sun with Linux, so I don't think there is anything x86 centric about it. --Donald Teed On Wed, 14 Sep 2005, Jeff Michels wrote: > Hello, > > I've been using UDPCast for about a year now and it has saved our school > district from the cost of a commercial imaging program.

How to do an automatic reboot

by david aimé

Hello I use udpcast with several computers. After duplicating one hard disk to the others, i would like that the computers that received the data reboot automatically. But i don't know how to do this because udpcast don't allow us to do that with it's options. I'm waiting for your advice Aimé David _________________________________________________________________ MSN Messenger : personnalisez votre messagerie instantanée ! http://g.msn.fr/FR1001/866

udp-receiver portbase problem

by Raúl Sánchez Sánchez

16 years, 6 months

RE: Udpcast Digest, Vol 29, Issue 5

by Jeff Michels

Hello: I'm trying to use udp-receiver with a inirrd (PXE) image from your web with the portbase option. The client is configured to use port the 9600. When I launch udp-sender --portbase 9600 option no client listen it. However if I use the default port, it works fine. So clients are listening at port 9000 instead of 9600 how I wanted :( What I'm doing wrong? Hello, I am having the same issue when booting a computer via PXE and using udp-sender at the command line of our server. If I boot two computers using a CD and set one as the sender and one as a receiver using a port other than 9000, it works. This really hasn't been much of an issue as of yet because our server is really only powerful enough to send one image out at a time. In the future we will be getting a new system and it would be nice to be able to send out more than one type of image at a time. Thanks, Jeff Michels Technology Support Specialist The School District of Beloit
