TCP: SMB2 uses TCP as its transport protocol.

SMB2 runs on top of TCP ports 139 and 445 which are the same ports used by the older SMB protocol. The following table lists the version number and the operating that brought them.

To separate it from the older SMB protocol it uses a slighty different signature 0xFE 'S' 'M' 'B' instead of the older 0xFF 'S' 'M' 'B' signature.

It adds larger types for various fields as well as a fixed size header. SMB2 was introduced with Microsoft Vista and is a redesign of the older SMB protocol. Windows 8 introduced several new features, so Microsoft has decided to bump the revision number up to SMB v3.Īs the packet signature is the same for SMB versions 2 and 3, Wireshark uses the display filter smb2 for both versions.

SMB2 is a new version of the old Windows filesharing protocol SMB and is used for filesharing on modern and future Windows hosts.
