Debian JavaPackage does not currently support JDK 9, but we can use the useful script/packages made by WebUpd8 team.

Create the repository file:

1

3
# /etc/apt/sources.list.d/webupd8team-java.list
deb     http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main

add its key and install the JDK package auto installer:

1

3
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt update
apt install oracle-java9-installer

Dnsmasq is very useful to cache DNS requests and speedup home connections:

1
apt-get install dnsmasq

put in /etc/dnsmasq.d/local.conf:

1
2
3
4
no-poll
cache-size=300
server=84.200.69.80
server=84.200.70.40

put in /etc/dnsmasq.d/ the attached ads.conf file built on both MVPS hosts list and pgl.yoyo.org list (you can update this list with the attached update-dnsmasq-adsblock.rb script).

Restart the service:

1
systemctl restart dnsmasq

Auto flush cache every week, put in root crontab:

1
2
#  m   h   dom   mon   dow   command
   0   4     1     *     *   pkill -HUP dnsmasq > /dev/null 2> /dev/null

And put in /etc/resolv.conf:

1
nameserver 127.0.0.1
