Remarks

The GetAttributes event fires when an SFTP client sends an SSH_FXP_STAT, SSH_FXP_LSTAT or SSH_FXP_FSTAT request. Path is the file path. Flags specifies the set of file attributes the client is interested in.

File/Directory Attributes are specified using the following values:

FileType: The type of file. Can be one of the following values:

• SSH_FILEXFER_TYPE_REGULAR (1)
• SSH_FILEXFER_TYPE_DIRECTORY (2)
• SSH_FILEXFER_TYPE_SYMLINK (3)
• SSH_FILEXFER_TYPE_SPECIAL (4)
• SSH_FILEXFER_TYPE_UNKNOWN (5)
• SSH_FILEXFER_TYPE_SOCKET (6)
• SSH_FILEXFER_TYPE_CHAR_DEVICE (7)
• SSH_FILEXFER_TYPE_BLOCK_DEVICE (8)
• SSH_FILEXFER_TYPE_FIFO (9)

FileSize: The file size, in bytes.

FileOwner: The file owner. If the ProtocolVersion configuration option is "3" (default), this field should be a numeric Unix-like user identifier. V4-V6 of the SFTP Protocol allow an arbitrary string.

FileGroup: The file owner group. If the ProtocolVersion configuration option is "3" (default), this field should be a numeric Unix-like group identifier. V4-V6 of the SFTP Protocol allow an arbitrary string.

FilePermissions: The POSIX-style file permissions.

FileATime: The file last-access time, in milliseconds since Jan 1, 1970 in UTC.

FileCreateTime: The file creation time, in milliseconds since Jan 1, 1970 in UTC.

FileMTime: The file last-modified time, in milliseconds since Jan 1, 1970 in UTC.

FileAttrBits: The file attributes, as a combination of the following values:

• SSH_FILEXFER_ATTR_FLAGS_READONLY (0x00000001)
• SSH_FILEXFER_ATTR_FLAGS_SYSTEM (0x00000002)
• SSH_FILEXFER_ATTR_FLAGS_HIDDEN (0x00000004)
• SSH_FILEXFER_ATTR_FLAGS_CASE_INSENSITIVE (0x00000008)
• SSH_FILEXFER_ATTR_FLAGS_ARCHIVE (0x00000010)
• SSH_FILEXFER_ATTR_FLAGS_ENCRYPTED (0x00000020)
• SSH_FILEXFER_ATTR_FLAGS_COMPRESSED (0x00000040)
• SSH_FILEXFER_ATTR_FLAGS_SPARSE (0x00000080)
• SSH_FILEXFER_ATTR_FLAGS_APPEND_ONLY (0x00000100)
• SSH_FILEXFER_ATTR_FLAGS_IMMUTABLE (0x00000200)
• SSH_FILEXFER_ATTR_FLAGS_SYNC (0x00000400)
• SSH_FILEXFER_ATTR_FLAGS_TRANSLATION_ERR (0x00000800)

FileAttrBitsValid: A mask specifying which bits in FileAttrBits are supported by the server.

OtherAttributes: A semi-colon (';') delimited list of Name=Value pairs of other attributes supported by SFTP. These include:

• MIMEType (String)
• AllocationSize (64-bit int)
• ATimeNS (int): ATime nanoseconds
• CreateTimeNS (int): CreateTime nanoseconds
• MTimeNS (int): MTime nanoseconds
• TextHint (8-bit int)
• LinkCount (int)
• UntranslatedName (String)

FileMimeType: The MIME type of the file.

Valid status codes are:

• SSH_FX_OK 0
• SSH_FX_EOF 1
• SSH_FX_NO_SUCH_FILE 2
• SSH_FX_PERMISSION_DENIED 3
• SSH_FX_FAILURE 4
• SSH_FX_BAD_MESSAGE 5
• SSH_FX_NO_CONNECTION 6
