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.
Nate Sbar.
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.
