Tor How-to

One method we strongly advise for surfing the web anonymously is Tor, a network of virtual tunnels allowing people to browse the Web without revealing their identity.

To surf the net anonymously using Tor, you have to install Tor Browser (available for all operating systems): a browser configured for anonymous browsing.

You can find detailed instructions here.

Consider however that Tor by itself is not all you need to maintain your anonymity. There are risks you need to be aware of and adjustments you need to make, all listed here.

Accessing A/I via Tor Hidden Service

Most of our services are available as a Tor Hidden Service, at the following address: wi7qkxyrdpu5cmvr.onion

Currently the available services include the main site (webmail, WebDAV access, etc.), email (SMTP for deliveries and POP/IMAP), Jabber and IRC, all of which are available at the above address.

Since .onion addresses are not particularly mnemonic, it is possible to retrieve the Hidden Service address with a DNS query:

$ dig  +dnssec +noauth +noquestion +nocmd +nostats TXT @
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 49449
;; flags: qr rd ra ad; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1

; EDNS: version: 0, flags: do; udp: 512
;; ANSWER SECTION:    9600    IN  TXT "wi7qkxyrdpu5cmvr.onion"    9600    IN  RRSIG   TXT 7 3 9600 20140110201148 20131211201148 24242 jshkdJJbHpxE0AzHcbQnr2mk75I/qawzLbObVX2A7lw79Sa5UEIjzHfl 75Vchn0095k9KTJqW2Y9yImxMTDuu3yXP1rmTzd9UXpEA7YFyPP5yOjU YUPS9BdzVOzYK9RsZSAOPom5fziDLzatcruI+/bPILbOOgR9vim/pZKr 0XI=

The thing to notice is the answer validated flag “ad” has been set. This example is using google public dns, however we recommend using a local validating resolver as explained here. Note: figuring out which .onion address to connect to is the subtle part of using an Hidden Service, we advise you to securely access this web page via SSL, verify the SSL certificate, and copy the .onion address to a local file or some other safe place.
