Recently I did an article about this very topic (“ Sharing Files & Folders Between Linux, Mac, and Windows“) which skimmed this topic, showing how simple it is to allow these different operating systems to see one another – with the help of Samba.
Samba linux windows#
If you restrict the Linux boxes to any of SMB1, 2, or 3 they all work fine with each other and with Windows 10.If you are either a power home user or you are in a business environment, you know the importance of machines being able to see one another. The underlying issue seems to be the Linux SAMBA negotiation around the version of SMB to use, which fails to agree a protocol. I added the following lines to /etc/samba/smb.conf in all Linux machines (servers and clients), and it all worked perfectly – all servers can now see shares on all clients, and vice-versa. Originally none of the devices could see remote shares on any other machine, with the Linux machines giving the error message “Ubuntu 20.04 failed to retrieve share list from server: Invalid argument”. While things have moved on since 2017 the problems around Linux SMB still exist in 2021, and this gave me the clues I needed to fix and secure my installation. 🥺 Was this helpful?

Please read our comment section below for detailed discussion. ConclusionĪnd there you have it, SMBv1 disabled on a Linux or Unix samba server to avoid security issues. However, on an older Linux and Unix distro you need to disable it manually to avoid security issues. NOTE: Please note that Samba version 4.11 removes SMB1 protocol version by default. Run the following command on Debian 8.x/Ubuntu 16.04 LTS Linux: Run the following command on CentOS 7/RHEL 7/Fedora Linux: Hence setting the following gives best option: By default SMB3 selects the SMB3_11 variant.

SMB3_11: Windows 10 technical preview SMB3 version (maybe final).SMB3_10: early Windows 10 technical preview SMB3 version.(By default SMB2 selects the SMB2_10 variant.) Used by Windows Vista and later versions of Windows. SMB2: Re-implementation of the SMB protocol.client max protocol – The value of the parameter (a string) is the highest protocol level that will be supported by the client.client min protocol – This setting controls the minimum protocol version that the client will attempt to use.Understanding min and max protocol levels in smb.conf The following seems to work with Windows 10/Linux clients too as noted by many in the comments section below:

However, you must disable SMBv1 on Samba server running on Linux or Unix-like system.įig.01: How to force SMB2 protocol in samba on Linux or Unix In short Linux/Unix users are not affected by this attack.
You must apply those patches ASAP on Windows operating systems.
Samba linux software#
Microsoft has released software updates for Windows XP and Windows Server 2003. To get back your files, you need to pay ransom payments in the cryptocurrency Bitcoin. If you are using older and unsupported operating systems such as Windows XP and Windows Server 2003, you will get infected. The attack spreads by phishing emails but also uses the EternalBlue exploit and DoublePulsar backdoor developed by the U.S. Introduction: WannaCrypt/WannaCry targets the Microsoft Windows operating system. Is it possible to disable SMBv1 on a Linux or UNIX-like operating system? I am a new Linux user and for security reasons and to avoid ransomware, I would like to disable the SMB1 protocol in samba configuration on a CentOS Linux version 7 server.
