Anonymous Instant Messaging

You can use internet applications with JonDo, if HTTP proxy settings are supported by your application. Please note: free services are limited in open ports. You can connect only to ports 80 and 443. These ports are used for web surfing (HTTP and HTTPS). For instant messaging like Jabber (XMPP) you have to use premium services.

You will need to enter the following in the HTTP proxy settings:

Host: localhost
Port: 4001

If you have to use a SOCKS proxy instead choose the same host and port values as above and make sure to use SOCKS version 5. If you have setup a different listen port than 4001 in JonDo you need to input it here instead of 4001 too. If your application supports both (HTTP and SOCKS proxy), please prefer using a HTTP proxy together with JonDonym.

Jabber Server (XMPP)

For anonymous instant messaging you have to create a new account first. Do not use your old, well known account with JonDonym and believe, you are anonymous. A list of useable Jabber servers you may find at jabberes.org or xmpp.org. Have a look at the privacy statement at the website of the selected server before you register your account. Some recommended Jabber servers with a high amount of users are:

jabber.org
secure-jabber.biz (no inbound registration, create your accout at the website)
jabber.ccc.org
jabber.dk (donations are welcome)
swissjabber.org (donations are welcome)
draugr.de (donations are welcome, SSL certificates signed by CAcert.org)

AnonJabber Project

AnonJabber is a project powered by the certified mix operator Delta-Protect Ltd. It offers distributed Jabber servers that can only be used with particular JonDonym premium cascades (see below).

server	SHA1 fingerprint of SSL certificate
anonjabber.net	2B:C6:69:EF:90:77:4F:45:47:33:3E:E1:31:C9:6C:30:A9:41:1A:B3
anonjabber.com	DD:35:E2:66:B6:B3:81:2E:6D:41:2B:41:98:5A:8D:AB:00:83:33:74
anonjabber.de	EF:9A:10:CC:AE:FB:26:31:1E:5C:F3:57:80:7A:2B:D1:2A:69:74:0B
anonjabber.eu	F0:4B:FA:C1:E1:41:21:55:BA:AD:1D:AA:9E:09:74:B6:02:75:35:4A
jabber-secure.net	79:EA:4C:AF:C4:53:19:4D:4D:C5:AD:C3:F1:27:3A:28:A5:FA:CC:3E

All of these servers offer SSL encryption, inbound registration and do not log any information about login and logout times. Because these servers are financed by earnings get from premium mixes, you can use them only with the following mix cascades:

Neptun-Wombats-Shamrock
Locke-Goose-Pluto
Fondue-Montesquieu-Uranus
Koala-SpeedPartner-Titan
Opossum-Berwald-Merkur

DNS Leaks

Warning: Many instant messaging clients break out the proxy for DNS request. An attacker can watch your internet traffic and feature out the Jabber server you were using. We have tested the following clients:

Miranda (Version 0.9.21) uses the proxy only for DNS request, if no DNS server was aviable. You can block DNS requests for jabber.dll with a personal firewall.
Psi (Version 0.14) leaks DNS requests, no patch aviable.
Pidgin (Version 2.7.11) leaks DNS request, a patch will be released in version 2.8.

Work around: You can set the IP address of the Jabber server in your account configuration. In this case no DNS requests are nessecary and no leaks will appear. You may use our DNS service webpage to get the IP address of the Jabber server.
