When executing:
mount -t cifs -o user=trapp,vers=2.1 //192.168.1.14/opsi_depot
/media/opsi_depot/
everything works as expected.
When booting from Kernel 3.16.0-5 both SMB-Versions work:
root@tt-debian8:~# uname -a
Linux tt-debian8 3.16.0-5-amd64 #1 SMP Debian 3.16.51-3+deb8u1
(2018-01-08) x86_64 GNU/Linux
This also happens when using non-virtualized Machines.
kind regards,
Thomas Trapp
