Can't connect via LAN plugin

[Clas Hortien]

Hi,

I try to connect via LAN plugin to a samba share on my raspberry pi machine. In samba I have the following settings:

[global]
workgroup = HOMESWEETHOME
netbios name = umbra

client min protocol = SMB2
client max protocol = SMB3
server min protocol = SMB2
min protocol = SMB2
protocol = SMB2

...

The share is defined like

[Backup]
path=/media/10TB/Backup
browseable=yes
writeable=yes
only guest=no
create mask=0777
directory mask=0777
public=yes

In the plugin I have SMB2 enabled and the correct user (pi) with his password set (I can login with that user and I can access the share from my Windows 10 machine with that user).

In the samba log file you can see messages like

[2019/08/22 14:21:51.767778, 0] ../libcli/smb/smb2_signing.c:171(smb2_signing_check_pdu) Bad SMB2 signature for message

Samba is fully updated to Version 4.5.16-Debian

Does this tell you anything ? What can I do to get this to work ?

Many thanks

I'm using the open source jmbj library for SMB2:
https://github.com/hierynomus/smbj

I couldn't find any bug reports about your specific error. You can try some other values for protocol:
SMB2_02: The earliest SMB2 version.
SMB2_10: Windows 7 SMB2 version. (By default SMB2 selects the SMB2_10 variant.)
SMB2_22: Early Windows 8 SMB2 version.
SMB2_24: Windows 8 beta SMB2 version.

Hi,
When I uncheck the SMB2 option I can connect succesfully .
