Ubuntu — Samba — SMB Protocol Versions

According to the Samba Official Wiki the Linux cifs kernel client has been included in the kernel since kernel version 2.5.42.

SMB3 is the now the default dialect (SMB3.02/SMB3/SMB2.1 dialects are requested by default).

CIFS protocol (and other old dialects) can be selected (by specifying “vers=1.0” or “vers=2.02” in the mount options.

vers=3.11	SMB3_11	Latest, more secure version. SMB3.11 can also be requested (vers=3.1.1). By default SMB3 selects the SMB3_11 variant.
vers=3.10	SMB3_10	Early Windows 10 technical preview.
vers=3.02	SMB3_02	Windows 8.1
vers=3.0	SMB3	Windows 8, Windows Server 2012. Mostly the same as SMB2_24
vers=2.24	SMB2_24	Windows 8 beta SMB2 version.
vers=2.22	SMB2_22	Early Windows 8 SMB2 version.
vers=2.1	SMB2_10	Windows 7, Windows Server 2008 R2. The default is SMB2 is selected.
vers=2.0	SMB2_02	Vista SP1, Windows Server 2008
vers=1.0	SMB1	NT1 i.e. Windows 95, NT 4.0

Specify with “vers=” and consider that the Linux kernel does not fully support all of the features in these new SMB versions. The newest, most secure dialect, SMB3.11 can also be requested (vers=3.1.1).

Add the following lines to /etc/samba/smb.conf

TODO: Some of these may not work — so try different combinations. PETER=FIX this

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

Configuration to enable SMBv2

Find the [global] section and append the following line:

. [global] . min protocol = SMB2 .

WannaCry can spread via SMBv2 as well:

The following gives best options:

client min protocol = SMB2 client max protocol = SMB3

server min protocol = SMB2_10 client max protocol = SMB3 client min protocol = SMB2_10

Errors

smbclient -U=username -N –command=”dir Directory/*” //192.168.0.1/Directory

protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

How to tell the version of Samba running

Samba is a free re-implementation of the SMB/CIFS networking protocol which creates a compatible way of sharing files with Windows computers on Linux and BSD computers. This post looks at how to tell which version of samba is running on the server from the command line.

Use the smbstatus command from the command line to show the version, as well as some other useful information:

The first line output from the command is a blank line but the second contains the version number. For example, the second line output from the command on a CentOS 5 machine might look like this:

Samba version 3.0.25b-1.el5_1.4

The smbstatus command also shows who’s currently accessing shares, what shares are available and what files are locked.

Some full example output from the smbstatus command is as follows (I’ve changed the real folder/share names to exampleN):

Samba version 3.0.25b-1.el5_1.4 PID Username Group Machine ------------------------------------------------------------------- 31784 chris chris laptop (192.168.1.177) 2389 chris chris desktop (192.168.1.10) Service pid machine Connected at ------------------------------------------------------- example1 2389 desktop Tue Feb 10 09:30:57 2009 example2 2389 desktop Tue Feb 10 09:30:57 2009 example3 2389 desktop Tue Feb 10 09:30:57 2009 example2 31784 laptop Tue Feb 10 06:41:58 2009 Locked files: Pid Uid DenyMode Access R/W Oplock SharePath Name Time -------------------------------------------------------------------------------------------------- 2389 1000 DENY_NONE 0x100001 RDONLY NONE /var/www example/www/images Tue Feb 10 09:38:30 2009 2389 1000 DENY_NONE 0x100001 RDONLY NONE /var/www example/www/images/gui Tue Feb 10 09:38:31 2009

DESCRIPTION¶

smbstatus is a very simple program to list the current Samba connections.

OPTIONS¶

The higher this value, the more detail will be logged to the log files about the activities of the server. At level 0, only critical errors and serious warnings will be logged. Level 1 is a reasonable level for day-to-day running — it generates a small amount of information about operations carried out.

Levels above 1 will generate considerable amounts of log data, and should only be used when investigating a problem. Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic.
