JonDo's features
The program JonDo allows your browser to visit
websites through an IP address within the JonDonym system and to encrypt your data traffic. This
means that neither the contacted server, nor any eavesdropper on your
connections, nor the operators of the JonDonym service themselves can realize
which webservice you use.
Basically all programs for which you can configure a HTTP proxy can used
together with JonDo.
Please note: free services can only contact destination ports
80 and 443, which are used for the HTTP and HTTPS protocol. You can use these
services only for web browsing and ftp downloads. All other web services
you can use only with premium services.
- For web browsing we recommend JonDoFox.
- Messengers, like Pidgin,
are recommended with the Jabber protocol and
the OTR plugin.
- WinSCP is a Windows program for the secure data transfer from
and to a server.
The usage of premium services with SOCKS proxies moreover allows for
an additional anonymization of the following applications:
- IRC Chat Clients (e.g. Chatzilla).
- Privacy friendly email clients like Mozilla Thunderbird.
- Other programs for which you can configure a SOCKS proxy.
It is possible, with the help of "proxifier" tools (e.g. proxychains), to use applications via JonDonym which are not capable of proxy support by themselves. E.g:
- Unobserved administration of servers via SSH
- Messenger application Kpoete (KDE)
What is JonDo?
- JonDo is an application that spoofs your own IP address for Internet access using certain
applications (e.g. by the web browser).
- JonDo multiply encrypts the data sent over JonDonym. Neither your access
provider nor JonDonym operators (except for the last one in each cascade) can see your plaintext data.
- JonDo is an Anti-Censorship-Application that allows
access to otherwise blocked Internet sites. Users may configure their JonDo
as a forwarding server in order to
allow others access to the JonDonym service.
- JonDo is open source and free. The program offers access to both free and
paid (premium) services.
- JonDo filters and anonymizes HTTP
headers - but only for unencrypted connections (not HTTPS). You should
additionally use JonDoFox in order to also
filter encrypted connections.
- JonDo is available on all major systems (Windows, Mac OS X, Linux).
- JonDo was and is developed by the JonDos GmbH in cooperation with German
universities (TU Dresden, Universität Regensburg)
and privacy organizations (Unabhängiges Landeszentrum
für Datenschutz Schleswig-Holstein).
What is JonDo not?
- JonDo does NOT make your PC's or router's IP
address invisible. Your IP address is assigned to you by your ISP, and
it is inalterable by third parties. You need the IP so that the JonDo
client may successfully connect to JonDonym services on the Internet. When
using JonDo, you are surfing with servers (mixes) on the Internet that all
have their own separate IP address. The websites accessed by you will only
see this respective outgoing address and not yours.
- JonDo does NOT regularly change the outgoing IP address, but retains the
same outgoing IP as long as it stays connected to the same mix cascade.
This could be minutes, hours or even days. The IPs of JonDonym mixes are
public anyways. Changing the outgoing IP would therefore not achieve
additional security.
- JonDo does NOT hide the MAC address of
your PC or router. The MAC address is used by your ISP to assign you your
IP address in the first place, and it is not visible on the Internet
besides that anyhow.
- JonDo is NOT a filesharing anonymization tool. You may run certain P2P
applications with JonDo, but you will not be able to upload data
yourself.
- JonDo can NOT anonymize emails. This would require special, additional
data filtering in the email client itself.
- JonDo does NOT integrate with your operating system, i.e. every
application has to be configured separately for
it.
- JonDo does NOT accelerate Internet access. When surfing with premium
services you probably won't notice any big loss in speed though.
- JonDo is NOT JonDonym. JonDonym summarizes all the accessible services in
JonDo in one term and describes the technology itself.
- JonDo is NOT JonDos. JonDos is the company that develops most of
JonDo.
- JonDo can NOT use random "anonymous" proxies (e.g. those on lists of open
proxies) to create an anonymous connection. This would be a totally unsafe method that does not
lead to anonymization.
- JonDo does NOT filter plugins, scripts or HTTPS websites. To secure your
browser as a whole you best use JonDoFox.
- JonDo is NO One-Click-Anonymization-Tool - something like that can and
will not really ever exist! Prudence is and remains maxim for Internet
security.
