Windows and duped machine names
by Yannick Gingras 28 Sep '06

28 Sep '06

Hi I'm wondering if there is a way to set the machine name automatically after the broadcast. I heard that the last version of Ghost do something like that. For the GNU/Linux boxen I can autoset the hostname from a small script in init.d. I don't know much about Windows networking. Is the hostname in some file that we can write to by just mounting the partition? Do we have to mess with the registry? All the boxes connect to a Samba PDC. Can I copy the machine accounts and let them share the SID? -- Yannick Gingras

cast-o-matic reboot checkbox
by Dale Hofkens 27 Sep '06

27 Sep '06

Hi, Is it possible that the Reboot system after udpcast? (only available with full-featured shell) option is not working on the website at the moment? We built various images lately but none of them reboot after receiving an image. Kind regards, Hofkens Dale

Unable to make udpcast in gcc 3.2.2
by Steven Shiau 21 Sep '06

Just noticed that 20060920 was released, so as usual, I compiled it in my RedHat 9 Linux with gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5). I can not compile it successfully. However, udpcast-20060619 works.

Udpcast cast-o-matic
by Stephane 20 Sep '06

20 Sep '06

Hi, A suggestion about: http://udpcast.linux.lu/cast-o-matic/ Would it be possible to add javascript buttons to check/uncheck all drivers? Here is my proposition: =============================== <script type="text/javascript"> function checkAll(){ champs_input=document.getElementsByTagName('input'); for(i=0;i<champs_input.length;i++){ type=champs_input[i].getAttribute('type'); name=champs_input[i].getAttribute('name'); if(type=="checkbox"){ champs_input[i].checked=true; } } } function UncheckAll(){ champs_input=document.getElementsByTagName('input'); for(i=0;i<champs_input.length;i++){ type=champs_input[i].getAttribute('type'); name=champs_input[i].getAttribute('name'); if(type=="checkbox"){ champs_input[i].checked=false; } } } </script> =============================== An to test: =============================== <p><a href="javascript: checkAll();">Check All</a> / <a href="javascript: UncheckAll();">Uncheck All</a></p> =============================== Thank you very much! -- Stéphane.

cast-o-matic image gives error
by Dale Hofkens 20 Sep '06

20 Sep '06

Hi All, We are using Udpcast for some time now to clone pc's, and it's working excellently, thanks for all the work that went into this project. Recently we have changed hardware on our systems we clone, so i went to the cast-o-matic site and made a new image. We built a new client image on 20/9/2006 and download the new kernel (2.6.17.13) to include on our pxe server. We use LZOP compression, and this is what gives an error. On the clients we receive the following message LZOP: Applet not found as an error. After that the system gives a message it wont reboot and ends. We dont't have this error with gzip compression, but the image that resides on our server is LZOP and i read on the udpcast website that lzop is the preferred compression method. Could it be that we do something wrong, or is there a bug in the latest udpcast version/cast-o-matic site. Thanks for looking into this. Kind regards, Hofkens Dale ----------- Settings used : pxe image e100 , ata_piix dhcp used port 9000 no udpcast paramaters compression : lzop transfer direction : receiver use ff shell reboot system do not blank screen

Building offline with RPM and 'Do not blank screen'?

Hi, I don't find any parameter to avoid blanking screen when buiding bootcd-image offline with rpms... Is it the default way it works? Thanks! -- Stéphane.

Building offline and LZOP...
by Stephane 20 Sep '06

20 Sep '06

Hi, I build udpcd.iso offline using rpm->alien->deb and lzop compression doesn't seem to work. (I use 20060917 version) When I choose lzop, at the moment I press a key to launch opéreation, I get: lzop: applet not found And then it seems sot start but it send 0 bit and then print: Transfer complete /bin/lzop is present on live system running. What do you think about it? Thanks! -- Stéphane.

Finding the slowpoke machine when ID numbers scroll away
by D G Teed 17 Sep '06

17 Sep '06

We have a bunch of notebooks to image and the guys aren't willing to wait for the occassional messed up notebook to image if it is dragging all of the others down. When one is showing as missing packets continually, they want to disconnect it and carry on with the others. The problem is that with a recent version of udpcast we are noticing that there are many "Press any key to start" messages filling the screen of each client, so we can't see what node number a client is. Is there any way to either: - eliminate the high number of repeated "press any key" appearances on the clients, or - get the node id of the udpcast client from the client console, or associate its udpast node number with an IP. --Donald Teed

typo in "busyboxUsage" ?
by Tom Carpenter 17 Sep '06

17 Sep '06

The "busyboxUsage" file in "udpcast-20060619.tar.gz" contains the following line: "\t--slice-sice\tinitial slice size\n" \ is "sice" a typo, i.e. should it read "size"? -Tom Carpenter
