I wanted to share a directory (e.g. /share) but it didn’t work, only the users home directory worked well. The reason was “AppArmor” (you find it in the YaST Control Center), disable or configure it well, then it works.

For example when creating a big file for an iSCSI image file, a fast way is to use “fallocate”:

fallocate -l 100GB disk01.img

Go to /etc/ifplugd/action.d/ and rename the ifupdown file to ifupdown.original
Then do: cp /etc/wpa_supplicant/ifupdown.sh ./ifupdown
Finally: reboot

Send hostname to DHCP Server:
/etc/dhcp/dhclient.conf:
send host-name “xxxx”;

Think it should be without the domain name!

At the windows dhpc server check that the option “Dynamically update DNS A and PTR records for DHCP clients that do not request updates” is enabled.
