AdBlocking on Sailfish OS via /etc/hosts
There are some apps in Openrepos which do not seem to work anymore for SFOS 4.x. But you don't really need an app, all you need is a systemd timer & service and a simplistic shell script.
> cd /etc/systemd/system > nano hosts.timer hosts.service > systemctl daemon-reload > systemctl enable hosts.timer
[Unit] Description=Update /etc/hosts [Timer] WakeSystem=false OnCalendar=Sat *-*-* 16:00:00 RandomizedDelaySec=1h AccuracySec=1h Persistent=true [Install] WantedBy=timers.target
So once a week on Saturday at roughly 16:00. Adjust to your liking.
man systemd.timer for further options.
[Unit] Description=Update /etc/hosts [Service] # Un/comment as required: #ExecStart=/home/defaultuser/.local/bin/hosts ExecStart=/home/nemo/.local/bin/hosts
#!/bin/bash # see https://github.com/StevenBlack/hosts/ for alternatives url="https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/fakenews-gambling-porn-social/hosts" cd /etc || exit 1 curl --retry 20 --retry-all-errors --retry-connrefused --retry-delay 5 "$url" | grep '^0\.0\.0\.0' > hosts.new || exit 1 sed -i '/0\.0\.0\.0 0\.0\.0\.0/d' hosts.new cat hosts.editable hosts.new > hosts.tmp && mv hosts.tmp hosts && rm hosts.new
The script removes some useless fluff and then combines this data with hosts.editable into the new hosts file.
/etc/hosts is only overwritten when all this succeeds.
Make sure that
- ~/.local/bin/hosts is marked executable:
chmod +x ~/.local/bin/hosts
- The file /etc/hosts.editable exists and contains the default contents of /etc/hosts (before any manipulation). Here it is:
127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6
It seems that a full reboot is required for the new hosts file to take effect for the sailfish-browser.
Android App Support-up-
It also works for Android Apps, explained here:
> mv /system/etc/hosts /system/etc/hosts.old > echo 'lxc.mount.entry = /etc/hosts system/etc/hosts none bind,create=file 0 0' >> /var/lib/lxc/aliendalvik/extra_config
