The minimum version for use of the Linux kernel SMB3 support is kernel version 3.12 (or backport of cifs.ko module version 2.02 or later) but kernel version 4.11 or later is recommended due to the addition of the SMB3 share encryption security feature. The default dialect was changed to SMB2.1 or later in the 4.14 Kernel.

While SMB 2.x was optimized for IW data access over 1 Gbps networking, SMB 3.0 was designed to provide application data access. Microsoft had to compete with 1 GbE and 10 GbE iSCSI as well as 4 ...

CIFS (Common Internet File System) and SMB (Server Message Block) are both Windows file-sharing protocols used in storage systems, such as network-attached systems (NAS). The key difference between CIFS and SMB is that CIFS is a dialect of SMB – a particular implementation of the SMB protocol. The CIFS protocol is now considered an outdated ...

Linux SMB 3.0 (SAMBA) doesn't follow the full spec. There is a company out there (Kooler may know) who OEM's a full SMB 3 stack, but its generally people like EMC using their code not QNAP etc. Some systems can't deal with the code signing requirements from a performance standpoint. (I know old HNAS's were pretty much ever going to …

SMB 3.0 is Microsoft's replacement for the "chatty" CIFS file access storage protocol that offers enterprise-class storage to Hyper-V deployments. With the release of Windows Server 2012 ...

The Server Message Block (SMB) Protocol is a network file sharing protocol, and as implemented in Microsoft Windows is known as Microsoft SMB Protocol. The set of message packets that defines a particular version of the protocol is called a dialect. The Common Internet File System (CIFS) Protocol is a dialect of SMB.

Port 445. Simply put, port 445 is used for file sharing over the network by windows. Microsoft made a change to run SMB over port 445 from Windows 2000. Port 445 is used by Microsoft directory services, known as Microsoft-DS. Port 445 is used by both TCP and UDP protocols for several Microsoft services. Microsoft active directory and domain ...

Is SMB 3.0 stable enough? the feature is highly sensitive and it is not worth taking the risk especially for businesses To understand what SMB 3.0 is, we need to understand that "Samba" is the Open Source/Free Software suite that makes Windows networking possible for our Linux-based NAS units.

YNQ™ Adds Server/Client SMBv3 Capabilities To WinCE. The SMB protocol was introduced to Win CE in version 6 back in 2006. Microsoft kept supporting the protocol including in Win7, but did not maintain the SMB library or introduce upgrades for Windows CE to incorporate later protocols – SMB2 and SMB3. The outdated versions of Windows …

SMB 3.02 is only negotiated when systems of these operating system versions are directly connected. SMB 3.02 is qualified with SMB3.02 signed and unsigned traffic over IPv4 and IPv6, and encrypted connections over IPv4 and IPv6. Authenticated connections between a server-side SteelHead and a domain controller are only supported over IPv4.

SMBLibrary is an open-source C# SMB 1.0/CIFS, SMB 2.0, SMB 2.1 and SMB 3.0 server and client implementation.

KSMBD is an opensource In-kernel CIFS/SMB3 server created by Namjae Jeon for Linux Kernel. It's an implementation of SMB/CIFS protocol in kernel space for sharing files and IPC services over network.

SMB 3 in Windows Server 2012 adds the capability to make data transfers secure by encrypting data in-flight, to protect against tampering and eavesdropping attacks. The biggest benefit of using SMB Encryption over more general solutions (such as IPSec) is that there are no deployment requirements or costs beyond changing the SMB Server …

This shows that DNS probably doesn't play any role in SMB 3 multipath. He tries to use the IP address of the RSS link but SMB 3 found and used the RDMA links. With Multichannel, SMB will create multiple TCP/IP connections for that single session (at least one per interface or more if they are RSS-capable).
