Just a simple question from a simple user. Lance Grover was talking about sending a disk to an image file on a server. Well, I have an external hard drive and I've been using dd and gzip to make images on the external drive, but I was hoping somebody out there could give me a quick tutorial on how to pipe udpcast to do the same thing because dd is really slow.

You can save to a file (using the -f option), no problem. For instance, you can do the following (assuming the disk is mounted on /extdisk):
udp-receiver -f /extdisk/myimage-file.img ...
However, it might still be interesting to find out *why* dd is so slow. If the cause is not with dd but elsewhere, udpcast will be just as slow.
For instance, if this external disk is an USB disk, make sure that you are indeed using USB 2 mode, and not USB 1. Or, if it is an SCSI disk, verify terminations, cabling, and verify that the best SCSI speed is used.
