NAME

       smbinfo  -  Userspace  helper  to  display SMB-specific file information for the Linux SMB
       client file system (CIFS)

SYNOPSIS

          smbinfo [-v] [-h] [-V] {command} {file system object}

DESCRIPTION

       This tool is part of the cifs-utils suite.

       smbinfo is a userspace helper program for the Linux SMB client file system (CIFS).  It  is
       intended to display SMB-specific file informations such as Security Descriptors and Quota.

       This  tool  works by making an CIFS_QUERY_INFO IOCTL call to the Linux SMB client which in
       turn issues a SMB Query Info request and returns the result. This differs from  getcifsacl
       which uses extended file attributes.

OPTIONS

       -v     Print version number and exit.

       -V     Verbose output.

       -h     Print help explaining the command line options.

COMMAND

       fileaccessinfo: Prints the FileAccessInformation class

       filealigninfo: Prints the FileAlignmentInformation class

       fileallinfo: Prints the FileAllInformation class

       filebasicinfo: Prints the FileBasicInformation class

       fileeainfo: Prints the FileEaInformation class

       filefsfullsizeinfo: Prints the FileFsFullSizeInformation class

       fileinternalinfo: Prints the FileInternalInformation class

       filemodeinfo: Prints the FileModeInformation class

       filepositioninfo: Prints the FilePositionInformation class

       filestandardinfo: Prints the FileStandardInformation class

       filestreaminfo: Prints the FileStreamInformation class

       fsctl-getobjid: Prints the ObjectID

       getcompression: Prints the compression setting for the file.

       setcompression -c <no|default|lznt1>: Sets the compression setting for the file.

       list-snapshots: Lists the previous versions of the volume that backs this file

       quota:  Print the quota for the volume in the form - SID Length - Change Time - Quota Used
       - Quota Threshold - Quota Limit - SID

       secdesc: Print the security descriptor in the form - Revision -  Control  -  Owner  SID  -
       Group SID - ACL - File types - File flags

       keys:  Dump  session  id,  encryption keys and decryption keys so that the SMB3 traffic of
       this mount can be decryped e.g. via wireshark (requires root).

NOTES

       Kernel support  for  smbinfo  utilities  requires  the  CIFS_QUERY_INFO  IOCTL  which  was
       initially  introduced  in  the  4.20 kernel and is only implemented for mount points using
       SMB2 or above (see mount.cifs(8) vers option).
