This is a great product! I have already used it a bunch, I imaged 59 computers on friday in an an hour an half. But I have some questions.
Question 1 Most of my machines have the same hardware, but some have had hard drives replaced. so some are bigger... If I go from a big hard drive to a smaller one I get and error but it seems to work just fine. But if I go from a smaller hard drive to a bigger one it says transfre complete. But when I restart the the computer (windows 98) I get invalid system disk. Is there any way or trick to be able to copy from a smaller drive to a bigger one?
This is very weird. Normally, I'd expect the opposite behaviour: i.e. copying to a smaller disk should break (because some data isn't copied, and because the OS is led to believe that the disk is bigger than it really is), but copying to a bigger one should work fine.
Maybe what's happening in your case is the following:
1. [Copy from large to small] During casual testing, the data that happens to be located at the end of the disk might not yet be needed, and hence the problem does not show up. However, continued usage _will_ show problems (even if the non-existant sectors were empty to begin with, eventually the OS _will_ try to store some data on them, and fail)
2. [Copy from small to large] Maybe an unrelated problem, such as different number of sectors and/or heads. Linux does not care about such things, but windows unfortunately does. This should not be a concern with newer hardware (where the "disk geometry" as seen by the OS depends only on the mode (LBA, Large, CHS), rather than on the physical geometry). However, when dealing with older hardware, there might be surprises...
Question 2 I have been trying to use the command line tool so I can store images on a server. I have a computer running Fedora core 2 and I can start the recieving process by typing in udp-reciever -f pIII98. It says the following: udp-reciever 2004-05-31 UDP reciever PII98 at 10.4.222.79 on eth0
On the sending machine I boot off the cdrom and start the sender, this is what it says:
UDP sender 2004-05-31 using mcast address 234.4.222.2 compressed UDP sender for /dev/hda/ at 10.4.222.2 on eth0 Broadcasting control to 10.255.255.255
Both should be set to use the default port of 9000, but they won't connect. They will both just sit there like this. If I boot them both off the cd they will connect just fine. I am only not able to connect when using the command line tool.
Possibly mismatched netmasks, or firewall rules.
Try running tcpdump on your server box (where you run the command line version) and check what packets are send and received.
If anybody could help me out that would be great. Thanks Kevin Christensen Kuna Joint school district Kuna Idaho
