Comment on Monitoring and restart server services (Apache, Mysql, Bind) with Monit to prevent server downtimes by admin.
One little note to make here:
/var/run/apache2.pid
The monit rc config as explainedf in step 3 is configured to monitor (alert and restart) BIND (Named) DNS resolver server
If wherever you configure monit you have no don’t use bind, comment inside my sample monitrc:
check process named with pidfile /var/run/bind/run/named.pid
start program = "/etc/init.d/bind9 start"
stop program = "/etc/init.d/bind9 stop"
if failed host 127.0.0.1 port 53 type tcp protocol dns then restart
if failed host 127.0.0.1 port 53 type udp protocol dns then restart
if 5 restarts within 5 cycles then timeout
##check process named with pidfile /var/run/bind/run/named.pid
## start program = "/etc/init.d/bind9 start"
## stop program = "/etc/init.d/bind9 stop"
## if failed host 127.0.0.1 port 53 type tcp protocol dns then restart
## if failed host 127.0.0.1 port 53 type udp protocol dns then
restart
## if 5 restarts within 5 cycles then timeout

Monitoring and restart server services (Apache, Mysql, Bind) with Monit to prevent server downtimes
If you have more than one server that you need to monitor, then you can use M/Monit– an extended version of Monit that provides a simple way to monitor multiple machines.

Also the monitrc config from my article is configured to check and report for “disk full” and low disk space on /dev/md0 which used to be a software mirror type RAID1. Therefore config in monitrc reads:
check device disk1 with path /dev/md0
On other non-RAIDed disks, usually the disk to monitor is /dev/sda1 or /dev/sdb1
Thus if you’re not using a hardware or software mirror probably this config section should be substituted with:
check device disk1 with path /dev/sda1, i.e.:
check device disk1 with path /dev/sda1

Also i’ve figured out later. This alerts as I configured in this article might be sometimes really annoying if you receive e-mails every few seconds. Hence it might be good idea to comment alerts in my monitrc sample conf:
To do so, remove or comment lines in Apache and MySQL monit config section:
## if cpu usage is greater than 80 percent for 3 cycles then alert
## if cpu is greater than 50% for 2 cycles then alert

Christ is Risen Eastern Orthodox Resurrection Paschal Greeting in Different Languages
Hi Stan,
I guess you cannot read the writtings on the icon as it is in cyrillic.
This is not Saint Mary and Saint Peter but Adam and Eve written in cyrillic on top of the icon.
Actually in orthodoxy it is a requirement for the depicted personalities, especially saints to have
written on the names of the saint and have the Halo. If you look closely at the picture you will notice
the two Adam and Eve are missing a Halo. The only person with a Halo in the icon is Saint John the Baptist.
Best Regards

–rwo, –report-warnings-only
This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
be used to force other items of information to be displayed.
–sk, –skip-keypress
When the –check command option is used, after certain sections of tests, the user will be prompted to press the return key
in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.

As rkhunter check, can be pretty annoying and ask you to press keypresses multiple times and spit you a lot of unnecessery data a very good useful option arguments are:

Warning: The SSH and rkhunter configuration options should be the same:
SSH configuration option 'PermitRootLogin': yes
Rkhunter configuration option 'ALLOW_SSH_ROOT_USER': no
