Understanding min and max protocol levels in smb.conf client min protocol - This setting controls the minimum protocol version that the client will attempt to use I am running Samba 3.6 in SLES 11.4. I recently added in /etc/samba/smb.conf in the [global] section the following. min protocol = SMB2; max protocol = SMB2; this was done to allow communication with Windows10 clients that are starting to come online, and also continue to work with existing win7 pc's in my CentOS-7 box, /etc/samba/smb.conf contains: server min protocol = SMB3_11 client max protocol = SMB3_11 client min protocol = SMB3_11. Some non-current windows versions don't support that version, you may need to try different values til you find one that works. Whatever you do, you don't want to use version 1

How to configure Samba to use SMBv2 and disable SMBv1 on

After some experimentation, I determined that removing min protocol = SMB3 and max protocol = SMB3 caused protocol = SMB3 to disappear from the testparm output. Because I hate unnecessary redundancy in config files, I decided to replace the two other lines with simply protocol = SMB3, and see if some improved Feng Shui might fix it In Kodi, go to Settings > Services > SMB client (you will need to change the settings level to Advanced or higher to access the SMB client option). Set both Max/Min protocol version to SMB3. Reboot. On Raspbian there isn't that option, but on Ubuntu 16.04 there is and samba is a lower version (4.3.11) min protocol = SMB2 max protocol = SMB3 But the client should ideally just match it via (example): client min protocol = SMB2 client max protocol = SMB3 Because of that option (config files), I don't believe anything needs to be changed on php-smbclient, but I've introduced smbclient_client_protocols, see branch issue53: a25e600 I'd like to try SMB2 / SMB3 between pogoplug and windows 8.1 but so far I can't get it to work. Windows 8.1 reports connection as SMB1. Here is my smb.conf. Should I add security to enable SMB3? [global] client min protocol = SMB2 client max protocol = SMB3 log level = 0 log file = /tmp/ server min protocol = SMB2_10 server max protocol = SMB2_10 I end up with Minshall+French symlinks. If I set: server min protocol = SMB3_02 server max protocol = SMB3_02 I end up with Minshall+French symlinks. @anodos is this all expected? The code you posted above says things like fallback to the old Conrad/Steve symlinks, implying they are.

If you find that the above max and min protocol versions just don't work for you in the smb.conf file, try protocol = SMB2 or whatever version you find will work between you devices. It seems that the way the file gets parsed is a bit open-ended or has changed over the years Which is the reason that Microsoft and most Linux security sites recommend the Samba server/client min protocol be set to SMB2. There is debate if the max protocol also needs to be set for server since the manual states the default is SMB3. I experimented with client max protocol If we use Samba server on Linux to share network folders, we can specify the minimum supported version of SMB protocol in the smb.conf file like the following: [global] server min protocol = SMB2_10 client max protocol = SMB3 client min protocol = SMB2_10 encrypt passwords = true restrict anonymous = 2 On Windows 7/Windows Server 2008 R Append server min protocol and server max protocol in /etc/samba/smb.conf to force usage of a minimum and maximum protocol: /etc/samba/smb.conf [global] server min protocol = SMB2_02 ; server max protocol = SMB3. See server max protocol in smb.conf(5) for an overview of supported protocols It basically comes down to some additions in the .smb/smb.conf file. You need to add or change to following 3 settings under the global headline. [global] client min protocol = SMB2 client max protocol = SMB3 client N..

[SOLVED] Samba: min protocol = SMB2 causes protocol

Running a Samba server, I guess it is a good idea to require encryption and SMB3. So I tried setting these two options in /etc/samba/smb.conf (see documentation) in the [global] section: smb encrypt = mandatory min protocol = SMB3 I realize however, that smbclient defaults to the highest possible protocol (SMB3_11 by the looks of it), and I figure if I do this in smb.conf... client min protocol = SMB3 client max protocol = SMB3 server min protocol = SMB3 server max protocol = SMB3 then the protocol should be locked down pretty good The open-source SMB toolkit's developers say the Samba 4.11 build, currently in preview, will by default set SMB2_02 as the earliest supported version of the Windows file-sharing protocol. This means clients without support for SMB2 or SMB3 are no longer able to connect to smbd (by default), the 4.11 release notes read

If you use Samba server on Linux to share network folders, you can specify the minimum supported version of SMB protocol in the smb.conf file like this: [global] server min protocol = SMB2_10 client max protocol = SMB3 client min protocol = SMB2_10 encrypt passwords = true restrict anonymous = I've tried adding both min protocol = SMB2 and min protocol = SMB3 and neither one has any affect.

SMB Protocol Negotiation Failed Normally SMB takes care of choosing the appropriate protocol for each connection. However, if the offered protocols are out of. Setting min protocol to core was a troubleshooting step. You should test and set it to the an appropriate level (i.e. the highest level supported by your clients, up to SMB2). In other words, start with 'core' and then move up until stuff starts breaking. As the SMB protocol evolved, new speed and security features were introduced Default: client max protocol = SMB3 Example: client max protocol = LANMAN1 client min protocol (G) This setting controls the minimum protocol version that the client will attempt to use. Normally this option should not be set as the automatic negotiation phase in the SMB protocol takes care of choosing the appropriate protocol min protocol = LANMAN2 max protocol = SMB3 Saya masih tidak sepenuhnya yakin tentang urutan protokol di Samba, tapi saya cukup yakin itu LANMAN2 setelah SMB1 I had to reboot the system in order to get the server min protocol = SMB3 recognized.

As for whether that solved the problem of detected the NAS over-the-network on a machine without SMB1 support enabled, on my Windows 10 laptop, I removed SMB1 support, searched the network, and lo-and-behold, I was able to find the NAS, so I'll say there's a strong chance that making SMB3 the default protocol resolves that problem. I would. I tried to configure Samba /etc/samba/smb.conf through: [global] protocol = SMB1 min protocol = SMB1 max protocol = SMB1 client min protocol = SMB1 client max protocol = SMB1 but nothing works. Windows CE cannot connect to the shared folder. I tried with Windows 10 and surprisingly it worked, but probably because I ran SMB1 support on Windows 10 After the change, it reverted my settings back to the FreeNAS defaults, which seems to be a min of SMB1 and a max of SMB3. I fixed that with an aux param of min protocol = SMB2 I propose that the setting be upgraded for security reasons to include min protocol = SMB2 as a default. If someone has to support legacy clients, they can set min. tried modifying /etc/samba/smb.conf with: client min protocol = SMB2 client max protocol = SMB3; I entered the smbconfiguration without any Slashes or Backslashes (so in host I only have the hostname of the device and in share only the sharename). I can mount the share successfully from another Ubuntu client where cifsutils is.

To specify a version of the CIFS/SMB protocol for use by the EVS, use the following commands: smb-max-supported-version - sets or displays the maximum supported version for both the server and the NAS client. The default is SMB2. smb-min-supported-version - limits the minimum supported version for both the server and the NAS client. The default. SMB1 is the older deprecated version of the protocol but it has been extended to support POSIX features (See [1]). The equivalent extensions for the newer recommended version of the protocol (SMB3) have not been fully implemented yet which means SMB3 doesn't support some required POSIX file system objects (e.g. block devices, pipes, sockets) In this tutorial, we learned how to mount smb share on Linux. Samba supports using SMB1.0, SMB2.0 and SMB3 and defines server min protocol option in smb.conf file. On Linux clients, you can install cifs-utils that provides means for mounting SMB/CIFS shares.

The Common Internet File System (CIFS) Protocol is a dialect of SMB. client min protocol = SMB2 client max protocol = SMB3 server min protocol = SMB2 server max protocol = SMB3. If I check the version of smbd on the Ubuntu box, it reports version 4.11.6-Ubuntu I don't understand why, if Ubuntu 20.04 is running SMB V3 (or V2) why I cannot access the shared files from Windows, which is also running SMB V3 (or V2), but when SMB V1 is enabled on Windows, I can access those shares even though the min protocol is set to V2 min protocol = SMB2 ea support = yes vfs objects = catia fruit streams_xattr. These entries are required because the AAPL (Apple) extensions to the SMB protocol are negotiated at the first connection which may, or may not be for the TM Backup. I suggest you delete the max protocol = SMB3 - clients & server will negotiate highest common.

UPDATE: I searched Ignoring invalid value 'SMB1' for parameter 'min protocol' with google and I landed on a forum where there was a guy complaining that with the new version of Debian he couldn't make his old printers work.Someone suggested him to put this in the SMB options: max protocol = NT1. min protocol = CORE. ntlm auth = yes. Well, I did, I started my PS2 and all games were there SMB version 1 is the old version of this protocol. Since it is outdated, it is no longer secure which opens the system to ransomware and other vulnerabilities

server min protocol = SMB2_10 Start and test winbind. The first line output from the command is a blank line but the second contains the version number. The client stuff is to make smbclient (if you use that) skip SMB 1 in negotiations. protocol = SMB3. We use port 139, this may be the problem or the old samba version we have Step1: open /etc/smb.conf configuration file with vi or vim text editor, type: $ vim /etc/smb.conf.

But you can opt to keep smb.conf as it is where SMB1 is diabled and do [1b] or [1c] which will then access your servers with an smb dialect somewhere between SMB2. Note that the SMB2 and SMB3 keywords map to the highest supported sub-version of that protocol (currently SMB2_10 and SMB3_11). This means that setting the minimum protocol to SMB3 would actually exclude Windows 8.1 (which uses SMB3_02).
