...ory/adv200005 Published: 03/10/2020 ? Workarounds The following workaround may be helpful in your situation. In all cases, Microsoft strongly recommends that you install the updates for this vulnerability as soon as they become available even if you plan to leave this workaround in place: Disable SMBv3 compression You can disable compression to block unauthenticated attackers from exploiting the vulnerability against an SMBv3 Server with the PowerShell command below. Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" DisableCompression -Type DWORD...

...n the other hand, NFS is a fully-featured filesystem that supports fancy features like locking and a full ACL system. SSHFS is a FUSE filesystem that will break a lot of software if you try to use it for anything more complex than 'ls' and 'cp'. For what it's worth, Samba with SMBv3 and the POSIX extension[1] is a lot more tolerant of bad connections, and presents itself as a real filesystem under linux. 1. https://wiki.samba.org/index.php/SMB3-Linux -- Jonathan Billings <billings at negate.org>

...64 machine. I am getting the NT_STATUS_INVALID_PARAMETER error string when running smb_raw_open_recv for a Windows 2012 R2 Preview remote host. I was unable to reproduce the error on other Windows platforms (works fine for Windows 2012 and other older versions). The remote host has SMBv1, SMBv2 and SMBv3 enabled. If I disable SMBv1 I can't even connect (getting error NT_STATUS_CONNECTION_RESET). If I enable just SMBv1 I get the NT_STATUS_INVALID_PARAMETER error, regardless of whether SMBv2 and SMBv3 are enabled or disabled. Any help is highly appreciated. Thank you, Mihai

...ns are enabled, the Unix file user, group, and permissions are stored as SMB ACL entries, and is translated from, to, and checked as Unix permissions by the Linux client itself, without server involvement. Since SMBv1's Unix extension is an obsolete "old, insecure, dialect" [1], while SMBv3's new POSIX extension is not finalized yet in Samba [2][3], I believe this feature provides a valuable option to achieve Unix compatibility if the Linux clients can be trusted (e.g. one user per share). To represent unmapped Unix user, group, and mode, three special SID ranges are used: S-1-5-...

Hi, I want to use the SMB3 POSIX extensions in the latest Samba (with SMB3.1.1, vers=3.1.1). By following the user manual, I have added the "posix" mount option when mounting, but it shows the following error messages. Error messages: [xxxxx] CIFS VFS: Server does not support mounting with posix SMB3.11 extensions. [xxxxx] CIFS VFS: cifs_mount failed w/return code = -95 Mount option:

FreeNAS / FreeBSD have native NFSv4 ACLs. They do however lack kernel oplock support so there are perhaps some caveats in that regard.

Hi, I have a customer who is able to access shares using the IP address of the Samba server (running 3.6.x - sorry, can't upgrade) but when they try to access the share using the short (netbios) name, they get "access denied" and are prompted for a username/password. Where would I look to figure out what's going wrong? Thanks, Rob

Whilst you have told us how you have setup your Windows machine, you have told us very little about the SMB client, just that it uses SMBv3. For all we know, they could be both Windows machines, though this is doubtful, or you wouldn't be asking here. Can you please tell us what OS you are running on the client. What version of Windows the server is running Please provide the output of 'testparm -s' run on the client. Ro...

Although we reached out to Hitachi support, we didn't specifically request for the smb.conf file from them. As a result, we're uncertain about the status of their Samba version, whether it's in standard or mangled form, and whether they're capable of providing us with the smb.conf file. I was wondering if there are any specific parameters or information that we should check from

Hi, after trying sshfs to mount a remote file system on a server with the result that sshfs will sooner or later get stuck and require a reboot of the client, I'm fed up with it and am looking for alternatives. So next I would like to use NFS over a VPN connection instead. To minimize the instances of the NFS mount getting stuck, it might be helpful to use autofs. What happens when the

Hi, folks, Just ran into a problem: someone with a new laptop, running Win 10, version 1709, tried to map their home directory (served from a CentOS 6.9 box, and it fails, with Windows complaining that it no longer supports SMBv1, and if you go to their site, you can install support for that manually.... The server running samba can *not* be updated to 7 - we have a lot of stuff based off
