7# -- empty lines and lines starting with '#', ';' or '//' are ignored
8# -- boolean options can be Yes/No or True/False or 1/0
9# -- you can PGP clearsign this file -- samhain will check (if compiled
10#    with support) or otherwise ignore the signature
11# -- CHECK mail address
12#
13# To each log facility, you can assign a threshold severity. Only
14# reports with at least the threshold severity will be logged

19# SETUP for file system checking:
20#
21# (i)   There are several policies, each has its own section. Put files
22#       into the section for the appropriate policy (see below).
23# (ii)  Section [EventSeverity]:
24#       To each policy, you can assign a severity (further below).
25# (iii) Section [Log]:
26#       To each log facility, you can assign a threshold severity. Only
27#       reports with at least the threshold severity will be logged
28#       to the respective facility (even further below).

34# Files are defined with: file = /absolute/path
35#
36# Directories are defined with:                  dir = /absolute/path
37# or with an optional recursion depth (N <= 99): dir = N/absolute/path
38#
39# Directory inodes are checked. If you only want to check files
40# in a directory, but not the directory inode itself, use (e.g.):
41#
42# [ReadOnly]
43# dir = /some/directory
44# [IgnoreAll]
45# file = /some/directory
46#
47# You can use shell-style globbing patterns, like: file = /path/foo*
