You cannot directly filter on SMB2 while capturing but you can capture for TCP port 445 External links Show only the SMB2 based traffic : smb2 Capture Filter
That is: conditional ACEs (use filter "nt.ace.cond"), system resource attribute ACEs (use filter "nt.ace.sra") and scopred policy ID ACEs (use filter "nt.ace.type = 19").Ī complete list of SMB2 display filter fields can be found in the display filter reference Smb2_dac_ A capture containing SMB2/GetInfo and SMB2/SetInfo with examples of Dynamic Access Control specific ACEs. Smb2-peter.pcap Simulated traffic (containing file reads/writes) between a Samba 4.4.x client and server on Arch Linux (from June 2016). Smb-on-windows-10.pcapng Handshake between two workstations running Windows 10
Ifstest.out The log output from the ifstest.exe tool A capture of two Vista beta2 boxes running ifstest.exe (XXX add links to preference settings affecting how DCE/RPC is dissected). The SMB2 dissector is partially functional. XXX - Add example traffic here (as plain text or Wireshark screenshot). 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.
