(Ad)sorber blocks ads by 'absorbing' and dumbing them into void.
Technically speaking, it adds ad-domains to the hosts file /etc/hosts
with a redirection to a non-existent ip 0.0.0.0
.
- Block advertisements system-wide, not only in the browser.
- Prevents annoying anti-adblockers from triggering.
- Update your blocked ad-domain list from external hosts-servers (like https://adaway.org/hosts.txt).
- Automatically update the hosts file per cronjob or systemd service.
- Save the last applied hosts-file as a backup if the current hosts-file contains broken ad-servers
- White- and blacklist.
Also it saves data, speeds up loading time and prevents some tracking of your browsing habits. For extensive privacy, I recommend using the script along browser add-ons like NoScript (for Firefox 56 and below), Privacy Badger and HTTPS Everywhere.
Currently we are using the following hosts lists:
- adaway.org
- yoyo.org
- & more to come.
To add your own hosts sources, just add them to the sources.list
file.
Usage: adsorber <operation> [<options>]
(Ad)sorber blocks ads by 'absorbing' and dumbing them into void.
(with the help of the hosts file)
Operations:
install - setup necessary things needed for Adsorber
e.g., create backup file of hosts file,
create scheduler which updates the host file once a week
However this should've been done automatically.
update - update hosts file with newest ad servers
restore - restore hosts file to its original state
(it does not remove the schedule, this should be used temporary)
revert - reverts the hosts file to the lastest applied host file.
remove - completely remove changes made by Adsorber
e.g., remove scheduler (if set)
restore hosts file to its original state
version - show version of this shell script
help - show this help
Options: (optional)
-s, --systemd - use Systemd ...
-c, --cron - use Cronjob as scheduler (use with 'install')
-ns, --no-scheduler - skip scheduler creation (use with 'install')
-y, --yes, --assume-yes - answer all prompts with 'yes'
-f, --force - force the update if no /etc/hosts backup
has been created (dangerous)
-h, --help - show specific help of specified operations
Documentation: https://github.com/stablestud/adsorber
If you encounter any issues please report them to the Github repository.
Note: to get further information about a operation run adsorber <operation> --help
You should run this command first.
The command will:
- backup your
/etc/hosts
file to/etc/hosts.original
(if not other specified inadsorber.conf
) - install a scheduler which updates your hosts file with ad-server domains once a week. (either systemd, cronjob or none)
- install the newest ad-server domains in your hosts file.
Possible options are:
-s, --systemd
-c, --cronjob
-ns, --no-scheduler
-y, --yes, --assume-yes
-h, --help
To keep the hosts file up-to-date.
The command will:
- copy the current
/etc/hosts
to/etc/hosts.previous
, if not disabled inadsorber.conf
- download ad-server lists from servers listed in
sources.list
- filter those and apply them to the systems hosts file
/etc/hosts
Possible options are:
-f, --force
-h, --help
To revert to the last applied hosts-file by Adsorber.
The command will:
- copy
/etc/hosts.previous
to/etc/hosts
, overwriting the newest/etc/hosts
.
This is useful if the new hosts file contains less ad-domains, because a server was unreachable and you don't want to loose the ad-servers supplied from this server.
Possible option:
-h, --help
To restore the hosts file temporary, without removing the backup.
The command will:
- copy
/etc/hosts.original
to/etc/hosts
, overwriting the modified/etc/hosts
by Adsorber.
Important: If you have a scheduler installed, it'll re-apply ad-server domains to your hosts file when triggered.
For this reason this command is used to temporary disable Adsorber, e.g. when it's blocking some sites you need access for a short period of time.
To re-apply run adsorber update
Possible option:
-h, --help
To completely remove changes made by Adsorber.
The command will:
- remove all schedulers (systemd, cronjob)
- restore the hosts file to it's original state
- remove all leftovers (previous hosts-file, etc)
Possible options are:
-y, --yes, --assume-yes
-h, --help
Used with install
.
It installs the systemd.timer scheduler, skipping the scheduler prompt.
Files are placed into /etc/systemd/system
by default.
Used with install
.
It installs the cron scheduler, skipping the scheduler prompt.
File is placed into /etc/cron.weekly/
by default.
Used with install
It will skip the installation of a scheduler. You'll need to update Adsorber manually.
Answers all prompts with yes
e.g.,
Do you really want to install Adsorber?
Do you really want to remove Adsorber?
It'll not answer prompts which may harm your system. But--force
will do it.
This will force the script to continue (dangerous) the update e.g.,
- Continue if no backup has been created, overwriting the existing hosts file.
If specified in conjunction with an operation, it'll show extended help about the operation.
To add or remove sources edit the soures.list
file which is created after the installation of Adsorber.
For a general configuration of Adsorber e.g., the path of the crontab installation, edit adsorber.conf
To add domains to the whilelist
or blacklist
edit the relevant files at the default config location.
The configuration's default location is at /usr/local/etc/adsorber/
if installed to system.
If not the config files should be placed at the scripts root directory.
Take a look here: TODO.md
You're free to implement things listed/not listed in TODO.md
to Adsorber. Any additions are appreciated. :)
