Image erstellung im Netzwerk #

dd ist ein bekantes Linux tool um Festplatten Images zu erzeugen. wenn mal alles ins Netz geschickt werden muss weil man keine Festplatte ausbauen möchte.

installiert man sich am besten netcat (nc) 

 apt-get install netcat

Server starten #

 nc -v -w 120 -p 3333 -l < /dev/null > image.gz

Server auf Port 3333 und wartet 120 sec.

Client sendet #

 dd if=/dev/hda bs=512 | gzip -c | nc -v -w 60 <image server ip> 3333
