DSTV Now on Amazon Fire TV Stick

Hopefully this tutorial will help others in South Africa get DSTV now running on a Fire TV Stick. The latest version of DSTV Now requires a newer version of Google Play Services to work.  Im not 100% sure whether this too requires the Google Playstore to operate, but Ive included links to a newer version of this as well. There are a number of ways of installing apk files on the fire sticks.  Ive found the simplest is by using the adb options built into the fire stick tv.  Another simple way is to get the downloader app installed on your device and install the packages one by one.  In order to get the system ready for adb following the tutorial supplied by amazon here .  Once ready download the adblink software from here    There are clients for windows mac and inux.

Update Openvas Feeds

To ensure openvas 9 is kept up to date and running the latest tests,  you need to sync the nvt, scap and cert data.  The best way to do this is to create a script that sync's the necessary data. Create a script under /usr/local/bin called update-openvas vi /usr/local/bin/update-openvas add the following contents to the file /usr/sbin/greenbone-nvt-sync /usr/sbin/greenbone-certdata-sync /usr/sbin/greenbone-scapdata-sync /usr/sbin/openvasmd --update --verbose --progress /etc/init.d/openvas-manager restart /etc/init.d/openvas-scanner restart save the file and make it executeable chmod a+x /usr/local/bin/update-openvas run the script to make sure it works and that there are no errors /usr/local/bin/update-openvas add the script to cron to run daily crontab -e add the following contents 1 1 * * * /usr/local/bin/update-openvas 1>/dev/null 2>/dev/null  the above cronjob will be run at 1 minute past 1 every day

Zabbix - adding apt update checks

Theres a number of articles on the internet on adding checks to package updates for Zabbix and Nagios.  I found the simplest way of doing this on Ubuntu is to use the update-notifier app-check application.   If you run /usr/lib/update-notifier/apt-check it will output the number of packages requiring updates as well as the number of security updates requiring updates. To apply this check to Zabbix add the following to a conf file within your zabbix_agentd.d directory. cd /etc/zabbix/zabbix_agentd.d vi apt_updates.conf  or something meaningfule  add the following content UnsafeUserParameters=1 Timeout=10 UserParameter=apt.available.updates,updates=$(/usr/lib/update-notifier/apt-check 2>&1);echo $updates | cut -d ";" -f 1 UserParameter=apt.security.updates,updates=$(/usr/lib/update-notifier/apt-check 2>&1);echo $updates | cut -d ";" -f 2 restart your zabbix agent The Timeout=10 is required as the script runs for a couple of seconds
