Setting Samba for very old client

Hi,

I need to set Samba share for very old client with unknown protocol.

The client is Dreambox 500hd satellite receiver. It works perfect with old NAS dlink nas-320. It is, I suppose, SMBv1 only NAS.

I have new server with OVM5.5.10-1 installed and it does not work.

I have added options in SMB/CIFS

client min protocol = LANMAN1

server min protocol = LANMAN1

client lanman auth = yes

client ntlmv2 auth = no

client NTLMv2 auth = no

client plaintext auth = yes

What I miss to set?

The connection from PC Win10 to share folder works. The problem is in protocol.

I can also add parameters on client Dreambox 500hd side. But it is unclear what is supported.

Any idea?

How to debug the connection. I do not see anything in log set to debug level. Where I should look?

Thanks

Martin

I answer by myself:

It works: Perhaps last 3 lines can be enought.

client min protocol = LANMAN1

server min protocol = LANMAN1

client lanman auth = yes

client ntlmv2 auth = no

client plaintext auth = yes

ntlm auth = yes
