Can't connect via LAN plugin

Post by *Clas Hortien » 2019-08-22, 12:40 UTC


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

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

only guest=no
create mask=0777
directory mask=0777

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
[2019/08/22 14:21:51.768122, 0] ../lib/util/util.c:555(dump_data) [0000] 09 DE 9D 09 2F 58 DC 8B 8A ED 78 11 D2 B3 F8 C5 ..../X.. ..x.....
[2019/08/22 14:21:51.768559, 0] ../lib/util/util.c:555(dump_data) [0000] A6 1B 11 B0 6C 51 72 27 24 B9 2C F0 41 F4 9A 3D ....lQr' $.,.A..=

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:

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.
