Build a home server - take two, part 2.

Update the system
ohlala# freebsd-update fetch
ohlala# freebsd-update install


Basic monitoring
We are going to use Smartmontools and we want to be informed by email when something happens with the harddisks. The default MTA installed is Sendmail. But it is far to big for our purpose, so we replace it with sSMTP:

Goto http://www.freebsd.org/ports/ and search for ssmtp. Here you get information about where sSMTP is situated in the /user/ports directory. Simply cd into that directory and start the installer.

ohlala# cd /usr/ports/mail/ssmtp/
ohlala# make install replace clean


I made a default installation. But install the extra patches. The "replace" command replaces sendmail as the default mailer with sSMTP. See also http://www.freebsd.org/doc/handbook/outgoing-only.html and http://www.freebsd.org/doc/handbook/mail-changingmta.html#MAIL-DISABLE-SENDMAIL. Continue with configuring sSMTP:

ohlala# mv /usr/local/etc/ssmtp/ssmtp.conf.sample /usr/local/etc/ssmtp/ssmtp.conf
ohlala# mv /usr/local/etc/ssmtp/revaliases.sample  /usr/local/etc/ssmtp/revaliases

ohlala# vi /usr/local/etc/ssmtp/ssmtp.conf
ohlala# vi /usr/local/etc/ssmtp/revaliases

Check drdata.blogg.se/2012/april/build-a-home-server-part-4.html for details.

Continue with installing Smartmontools:
Again search http://www.freebsd.org/ports/ for the location of Smartmontools in the /usr/ports directory and simply install by typing make install clean.

List your available harddisks. Here you can see the designations for the data disks:

ohlala# ls -l /dev/ada*

# The word DEVICESCAN will cause any remaining lines in this
# configuration file to be ignored: it tells smartd to scan for all
# ATA and SCSI devices.  DEVICESCAN may be followed by any of the
# Directives listed below, which will be applied to all devices that
# are found.  Most users should comment out DEVICESCAN and explicitly
# list the devices that they wish to monitor.
