Anonymous Instant Messaging

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

Host: localhost
Port: 4001
Type: HTTP (prefered) or SOCKS v5

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:

server	ports	file transfer proxy	BOSH/HTTP URL	commentd
jabber.ccc.org	5222, 80 5223, 443			by Chaos Computer Club SSL certificates signed by CAcert.org
jabber.dk	5222, 5223			donations are welcome
swissjabber.org	5222, 80, 5223, 443	proxy.swissjabber.com		donations are welcome SSL certificates signed by CAcert.org
draugr.de	5222, 80 5223, 443	proxy.draugr.de	https://www.draugr.de/http-bind/	donations are welcome SSL certificates signed by CAcert.org
secure-jabber.biz	5222			no inbound registration, create your accout at the website

If you were using JonDonym, XMPP file transfer is only possible by using file transfer proxies.
If your instant messaging client and the server were support BOSH/HTTP, you can use free mix cascades too. But may be you will get timeout errors time by time.

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.
Psi (Version 0.14) leaks DNS requests, no patch aviable.
Pidgin (Version 2.7.11) leaks DNS request, a patch was 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.
