bart_manifest

- system audit manifest file

Description

The bart(1M) command generates a manifest that describes the contents of a managed host. A manifest consists of a header and entries. Each entry represents a single file. Entries are sorted in ascending order by file name. Any nonstandard file names, such as those that contain embedded newline or tab characters, have the special characters quoted prior to being sorted. See Quoting Syntax.

Lines that begin with ! supply metadata about the manifest. The manifest version line indicates the manifest specification version. The date line shows the date on which the manifest was created, in date(1) form.

Some lines are ignored by the manifest comparison tool. Ignored lines include blank lines, lines that consist only of white space, and comments that begin with #.

In addition to metadata lines, the header contains the format comment block. This comment block lists the attributes reported for each file type.

To see the format of a manifest file, see EXAMPLES.

Manifest File Entries

Each manifest file entry is a single line of one of the following forms, depending on the file type:

fname D size mode acl dirmtime uid gid 
fname P size mode acl mtime uid gid
fname S size mode acl mtime uid gid
fname F size mode acl mtime uid gid contents
fname L size mode acl lnmtime uid gid dest
fname B size mode acl mtime uid gid devnode
fname C size mode acl mtime uid gid devnode

The fields of the manifest file entries are described as follows:

fname

Name of the file. To prevent parsing problems that are caused by special characters embedded in file names, file names are encoded as described in Quoting Syntax.

type

Type of file.

Possible values for type are as follows:

B

Block device node

C

Character device node

D

Directory

F

File

L

Symbolic link

P

Pipe

S

Socket

size

File size in bytes.

mode

Octal number that represents the permissions of the file.

acl

ACL attributes for the file. For a file with ACL attributes, this field contains the output from acltotext().

uid

Numerical user ID of the owner of this entry.

gid

Numerical group ID of the owner of this entry.

dirmtime

Modification time in seconds since 00:00:00 UTC, January 1, 1970 for directories.

lnmtime

Creation time for links.

mtime

Modification time in seconds since 00:00:00 UTC, January 1, 1970 for files.

contents

Checksum value of the file. This attribute is only specified for regular files. If you turn off context checking or if checksums cannot be computed, the value of this field is -.

dest

Destination of a symbolic link.

devnode

Value of the device node. This attribute is for character device files and block device files only.

Quoting Syntax

The rules file supports a quoting syntax for representing nonstandard file names.

When generating a manifest for file names that embeded TAB, SPACE, or NEWLINE characters, the special characters are encoded in their octal forms.

Examples

Example 1 Sample Manifest File

The following is a sample system manifest file. The file entries are sorted by the encoded versions of the file names to correctly handle special characters.
