Dr Data - Davor Vusir tells you how to...

Software installation
apt-get install git build-essential dkms linux-headers-`uname -r` bridge-utils virt-manager acpid smartmontools drbd8-utils gdisk sysstat lvm2 xorg pm-utils ssmtp

Configure Smartmontools
Start by edit /etc/default/smartmontools. Just uncomment the line "#start_smartd=yes". Continue with editing /etc//smartd.conf. I want to be informed by e-mail, so first I configured ssmtp. My ISP requires only valid mailaccounts. Start by edit /etc/ssmtp/ssmtp.conf:
#
# Config file for sSMTP sendmail
#
# The person who gets all mail for userids < 1000
# Make this empty to disable rewriting.
root=[email protected]

# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
mailhub=mailout.YourISP.org

# Where will the mail seem to come from?
rewriteDomain=YourISP.com

# The full hostname
hostname=ohlala.vusir.local

# Are users allowed to set their own From: address?
# YES - Allow the user to specify their own From: address
# NO - Use the system generated From: address
FromLineOverride=YES

Edit /etc/ssmtp/revaliases:
# sSMTP aliases
#
# Format:       local_account:outgoing_address:mailhub
#
# Example: root:[email protected]:mailhub.your.domain[:port]
# where [:port] is an optional port number that defaults to 25.
root:[email protected]:mailout.YourISP.org

Test your setting:
echo test | mail -s "testing ssmtp setup" [email protected]

Start smartmontools:
/etc/init.d/smartmontools start

The first line in /etc/smartd.conf is just sending a testmail when smartmontools starts.


Still Saturday. Turning off the server and do other fun stuff!
