samba - Apr 2020 - Unable to create / copy / delete a file on a SMBv1 only device using Samba 4.12.x

Hello.

I'm using Archlinux Mate with its testing repositories activated. I am only
the owner of an ISP "box" with an embedded HDD working only with SMBv1
protocol.

After I updated my archlinux box to Samba 4.12.0, I noticed that my access
was rejected.

I tweaked my /etc/samba/smb.conf to add this in [global] section.

"server min protocol = CORE
client min protocol = CORE"

After a reboot, I get back an access to the embedded HDD, but I cannot
create / copy a file without getting it created as a directory! A not
deletable one.

Here is the error log I got:

"Mar 31 23:28:40 fredo-arch-mate gvfsd[1096]: Kerberos auth with
'fred at WORKGROUP' (WORKGROUP\fred) to access '192.168.1.254'
not possible"

Do you have any idea or tips to make my HDD works back? The only workaround
I found was to block Samba to its version 4.10.x. Rebuilding gvfs did not
work either.

Thanks for your help.

Try doing a similar thing, but replace 'min' with 'max' and
'CORE' with
'NT1', you will also have to have SMBv1 installed on the clients.

This isn't a good idea really and is only a stop gap, Samba is working 
to remove SMBv1 entirely.
