# 
# -- empty lines and lines starting with '#', ';' or '//' are ignored
# -- boolean options can be Yes/No or True/False or 1/0 
# -- you can PGP clearsign this file -- samhain will check (if compiled
#    with support) or otherwise ignore the signature
# -- CHECK mail address

# To each log facility, you can assign a threshold severity. Only

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

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

##
## Severity for verification failures.
##
# SeverityReadOnly=crit
# SeverityLogFiles=crit
# SeverityGrowingLogs=crit
# SeverityIgnoreNone=crit
# SeverityAttributes=crit
# SeverityUser0=crit
# SeverityUser1=crit

## Dirs  : directory access problems
# SeverityDirs=crit

## Names : suspect (non-printable) characters in a pathname
# SeverityNames=crit

[Log]
##
## Switch on/OFF log facilities and set their threshold severity
##
## Values: debug, info, notice, warn, mark, err, crit, alert, none.
## 'mark' is used for timestamps.
##
##
## Use 'none' to SWITCH OFF a log facility
## 
## By default, everything equal to and above the threshold is logged.
## The specifiers '*', '!', and '=' are interpreted as  
## 'all', 'all but', and 'only', respectively (like syslogd(8) does, 
## at least on Linux). Examples:
## MailSeverity=*
## MailSeverity=!warn
## MailSeverity==crit

## E-mail

# MailSeverity=none

## Console
##
# PrintSeverity=info
