ITrig

Auch Linux Systeme sollten regelmäßig mit Updates versorgt werden. Wer nicht jedes System einzeln prüfen möchte, um zu sehen ob Aktualisierungen vorhanden sind, der ist mit "apticron" sicherlich gut bedient. Das Shellscript versendet Meldungen über Paket Updates automatische per E-Mail. Gerade bei der Verwaltung von mehreren Systemen kann eine automatische Info Gold wert sein.

Apticron unter Ubuntu - Debian einrichten

Installieren

apt-get install apticron

Konfigurieren

sudo nano /etc/apticron/apticron.conf

# apticron.conf
#
# set EMAIL to a space separated list of addresses which will be notified of
# impending updates
#
EMAIL="update@itrig.de"
#
# Set DIFF_ONLY to "1" to only output the difference of the current run
# compared to the last run (ie. only new upgrades since the last run). If there
# are no differences, no output/email will be generated. By default, apticron
# will output everything that needs to be upgraded.
#
DIFF_ONLY="1"

#
# Set LISTCHANGES_PROFILE if you would like apticron to invoke apt-listchanges
# with the --profile option. You should add a corresponding profile to
# /etc/apt/listchanges.conf
#
# LISTCHANGES_PROFILE="apticron"

#
# Set SYSTEM if you would like apticron to use something other than the output
# of "hostname -f" for the system name in the mails it generates
#
SYSTEM="server@itrig.de"
