Content lock
Providers of (e.g.) journalistic content have a legitimate right
– and of course the necessity – to make
money with their offers. Many providers offer users to pay for the content directly, individually or per
subscription
– or just to accept that the called up site contains advertisement.
Some providers reserve the right to lock the cost-free service if the user uses an ad-blocker. This lock
is also called “content lock”.
eBlocker’s aim is not to destroy the business plan of Internet providers. However, we do block ads
from advertising networks for these kind of sites, because nowadays the ad banners are used for
profiling. We do not help to avoid the named content lock. Instead we recommend to honor high-
quality content on a fair basis, so independent quality journalism is permanently preserved for all of
us.
Cookies
Cookies typically contain data about visited websites, that the web browser of this websites saves on
your computer and uses the next time you visit the same website again. Cookies however are not
fundamentally bad. They can increase the user comfort e.g. if you do not have to sign up again after
already having visited the website. Cookies can also be used to recognize the same individual on
different websites, so personality profiles can be generated comprehensively.
These tracking cookies are blocked from your eBlocker, so that they cannot even get into your
computer.
DHCP server and DHCP lease
The Dynamic Host Configuration Protocol (DHCP) enables the automatic integration of network
devices into all networks. A central server
– in such case the router - assigns the network
configuration to all devices. The lifetime of this assignment is called lease time. The administrator can
choose the existence of the lifetime at the router settings. The lease time can be indicated in seconds,
days or even weeks. If the DHCP server is changed during operation, all computers/devices must be
disconnected from the network once, so every device can be notified by the new DHCP server and
thus receives a DHCP lease.
Digital certificate
A digital certificate uses cryptographic methods, to verify the details to a communication partner
obligatory. For example, if a certain website is actually run by the named company. Digital certificates
are usually issued by trustworthy certification authorities that verified the details and take
responsibility for the correctness.
DNS Server
The DNS server (Domain Name System) is some sort of telephone book for the Internet. It translates
the server names from URLs and from email addresses to numerically IP addresses. The webserver
is identified and spoken to through the IP address.
LAN cable
The LAN cable (Local Area Network) or also called Ethernet cable, is a network cable that is required
for connecting the computer and other devices to your local net. Ethernet cables are often yellow
colored. The supplied Ethernet cable of eBlocker is obviously orange colored!
Malicious software

Trojans. Malicious software can get into your computer by visiting infected websites or by opening
