I want dd an image and save it to remote using tftp for example I'm trying to do
"dd if=/dev/mtd2" | save it to tftp server.
the direction of the file I have used in that code is wrong I'm trying my best to learn how it can be, this is the wrong code I made my self I mean half of it :'(
"dd if=/dev/mtd2" | tftp -l -p RootFS.bin 10.10.233.238 | dd of=File.bin
also if it's possible to transfer multiple folders and save it as one file on tftp for e.g I want to copy given below
or these directories
bin dev etc lib mnt opt proc root sbin sys tmp usr var
and save it as
My wrong code is
tftp -l /bin && /dev/ && /etc/ && /lib/ && /mnt/ && /opt/ && /proc/ && /root/ && /sbin/ && /sys/ && /tmp/ && / usr/ && /var/ -r Linux.bin -p 10.10.233.238
This is a tricky one, and it also appears you're using an embedded device (by the use of /dev/mtd).
It looks like you're trying to take an image of a block device, and create a 'bin' file on another machine. You may be overthinking this - a block device is openable as a file, and can be read by normal tools.
If that is what you are trying to achieve, the command you want to run is
tftp -l /dev/mtd2 -r file.bin -p 10.10.233.238
This opens the file /dev/mtd2 (even though it's a block device) and saves it as 'file.bin' on 10.10.233.238.
