CIFS servers can return 32-bit error information to clients usingStatus.Statusif the incoming client SMB has bit 14 set in theFlags2field of the SMB header. The contents of response parameters are not guaranteed in the case of an error return, and must be ignored. For write-behind activity...
* Reserved but not implemented 8. 命令:目前SMB协议共包含75种命令,不同命令通过SMB_Header中1字节大小的Command字段来区别定义,其中:SMB_COM_TRANSACTION2命令用于打开或创建一个共享文件或文件夹,设置它们的扩展属性。SMB_COM_NT_TRANSACT命令用于打开或创建一个文件或文件夹,并应用扩展属性EA或安全描述符SD。 9...
1) SMB servers return a maximum SERVER buffer size (MaxTransmotBufferSize) in the SMB negotiation response (SMB_COM_NEGOTIATE server response). This size is not the size of the complete network packet; it is just the SMB portion of the packet starting from SMB header. - Smb: ...

SMB v3中支持数据压缩,如果SMB Header中的ProtocolId为0x424D53FC也就是0xFC, 'S', 'M', 'B'.那么就说明数据是压缩的,这时smb会调用压缩解压处理的函数。 首先SMB会调用srv2!Srv2ReceiveHandler函数接收smb数据包,并根据ProtocoIId设置对应的处理函数。
smb.conf是samba最重要的配置文件,该文件定义了samba服务器的共享服务以及共享属性选项。下面将对该文件的语法结构及其一些重要配置选项进行简单说明。 一、语法格式 配置文件smb.conf的语法格式为: <file> :== { <section> } EOF <section> :== <section header> { <parameter line> } ...
The SMB2 Packet Header (also called the SMB2 header) is the header of all SMB 2 Protocol requests and responses. There
