I am looking for some script for FileChecksum monitoring , i have prepared the script but its not working as needed .
Strategy :
Code:
1) Copy ("passwd" "shadow" "/security/access.conf") to a new file location
2) Do , md5sum "/etc/passwd" "CopiedFile-Passwd" >tmp/HPOM_Checksum.log
3) Do , md5sum -c /tmp/HPOM_Checksum.log
if ("passwd" "shadow" "/security/access.conf") gets modified , the md5sum o/p string will be different
This can be checked from
4) md5sum -c /tmp/HPOM_Checksum.log
sample o/p
[root@oilvs011 tmp]# md5sum -c /tmp/HPOM_Checksum.log
/etc/passwd: FAILED
/var/opt/OV/log/hpom_passwd.md5: OK
5) If this gets modified , i again want to run the same loop.
Note : Whenever there is change in file the script has to copy the file again as in step 1
If you have any other better solution to work on this do let me know :
Code:
#!/bin/sh
CHECKSUM_PATH=/etc
AGENT_LOG=/var/opt/OV/log
declare -a arr=("passwd" "shadow" "/security/access.conf")
##now loop through the above array
for i in "${arr[@]}"
do
LIST_FILE=`ls -lrt "$AGENT_LOG" |grep "hpom_$i.md5" |wc -l`
echo $LIST_FILE
if [ $LIST_FILE -eq 0 ]; then
COPY=`cp "$CHECKSUM_PATH/$i" "$AGENT_LOG/hpom_$i.md5"`
fi
done
declare -a arr=("passwd" "shadow" "/security/access.conf")
##now loop through the above array
for j in "${arr[@]}"
do
CHECKSUM=`md5sum "$CHECKSUM_PATH/$j" "$AGENT_LOG/hpom_$j.md5" >/tmp/HPOM_Checksum.log`
CHECKSUM_STATUS=`md5sum -c /tmp/HPOM_Checksum.log |grep FAILED |wc -l`
echo $CHECKSUM_STATUS
if [ $CHECKSUM_STATUS -eq 1 ]; then
COPY=`cp "$CHECKSUM_PATH/$j" "$AGENT_LOG/hpom_$j.md5"`
echo `date +%b/%d/%Y-%H:%M:%S` Checksum Failed for $i >> /tmp/HPOM_Log_Checksum.log
fi
done
Thanks,

envconfig
envconfig(8) System Manager's Manual envconfig(8)NAME
envconfig - Configures the Environmental Monitoring daemon
SYNOPSIS
/usr/sbin/envconfig -c var=value
/usr/sbin/envconfig start | stop
/usr/sbin/envconfig -q
OPTIONS
Environmental Monitoring provides a means of detecting system threshold conditions, that if exceeded, could result in a loss of data or
damage to the system itself. To detect and notify users of critical conditions, the envmond daemon is used. This utility, envconfig, is
used to customize the envmond daemon. This section describes the envconfig options you can use to configure the daemon. Sets the vari-
ables that specify how the system environment is monitored. These variables are stored in the /etc/rc.config file and are read by the
envmond daemon at system start-up. If a variable is not set, the default value of that variable is assumed. Specifies the state of Envi-
ronmental Monitoring. If this variable is set to zero (0), the Environmental Monitoring package is not started during the system boot. If
this variable is set to 1, and Environmental Monitoring is supported by that platform, it is started during the system boot. The default
value is zero (0). Specifies the time (in minutes) that can elapse between the detection of a high temperature condition and the shutdown
of the system. The default value is 15 minutes. Specifies the threshold level that can be encountered before the envmond daemon broad-
casts a warning and suggested action. Specifies the frequency (in seconds) between queries of the system by the envmond daemon. The
default value is 60 seconds. Specifies the path of a user-defined script that you want to the envmond daemon to execute when a high
threshold level is encountered. The envmond daemon continues to check the environment after the script has executed and proceeds as needed
should the high threshold levels persist.
If you set this variable, the envmond daemon directs output from the script to /dev/console. Output is not displayed on standard
output or written to a file as this is not the behavior of the daemon. To display on standard output, explicitly specify the logger
command within the user defined script. Turns the envmond daemon on or off after system startup. Displays the values of
ENVMON_CONFIGURED, ENVMON_GRACE_PERIOD, ENVMON_HIGH_THRESH, ENVMON_MONITOR_PERIOD and ENVMON_USER_SCRIPT as specified in the
/etc/rc.config file. If a specified entry is not found, the environmental variable is not displayed.
DESCRIPTION
The envconfig utility is used to customize the envmond daemon. You must have root privileges to use this utility. Using this utility, you
can: Specify whether or not Environmental Monitoring is turned on or off at system startup. Specify how much time can elapse between the
envmond daemon encountering a critical condition and the daemon initiating an orderly shutdown of the system. Specify how frequently the
envmond daemon queries the system for information. Start and stop the envmond after Environmental Monitoring has been turned on at system
startup. Display the settings of the environment variables as specified in the /etc/rc.config file.
Note that the feature that you want to monitor must be supported on a given platform. For example, the AlphaServer 8400/GS140 supports
reporting of power supply and fan status, the current system temperature, and the maximum allowed system temperature.
EXAMPLES
The following procedure describes how you test for and start the environmental monitoring subsystem In multiuser mode, check the status of
the environmental monitoring subsystem as follows: # /sbin/sysconfig -q envmon envmon: env_current_temp = 35 env_high_temp_thresh = 40
env_fan_status = 0 env_ps_status = 0 env_supported = 1
If the value of env_supported is 0, configure the envmond daemon and reboot the system using either of the following methods: At the com-
mand prompt, enter the following command: # /usr/sbin/envconfig -c ENVMON_CONFIGURED=1 Use the rcmgr command as follows: # rcmgr set
ENVMON_CONFIGURED 1
This command will enable the envmond daemon and export the variable, creating the following two lines in the /etc/rc.configfile:
ENVMON_CONFIGURED="1" export ENVMON_CONFIGURED
You can use the /sbin/sysconfig command to view the system environment at any time. The envmond daemon will the print warning messages in
the event of a power supply failure, abnormality, or high temperatures. Error logs are logged in the /var/adm/binary.errlog.
In the following example, the system shuts down in 10 minutes if the temperature does not fall below the critical threshold.
/usr/sbin/envconfig -c ENVMON_GRACE_PERIOD=10
FILES
Databases that contains the values of the environment monitoring variables. Note that you must use the rcmgr comand to update the rc.con-
fig* files, particularly on clustered systems.
