Mixmaster (Whonix)¶
Although we highly recommend following the instructions on Mixmaster to compile the large-key version of Mixmaster, you can use the one that comes installed with Whonix, which is a bit outdated.
You should know that compiling Mixmaster (i.e., following
Mixmaster) would make the whole installation at ~/Mix
.
However, the one that comes with Whonix (installed from Debian)
uses different locations. There are only two important ones you
should know: the user files are at ~/.Mix
and the binary at
/usr/bin/mixmaster
. nymphemeral automatically searches for
Mixmaster files at those locations and you do not need to configure
anything (as explained on [mixmaster]).
Getting New Remailer Stats¶
Before you can use Mixmaster, you need to update the stats. We are going to use the pinger from the `Jeremy Bentham Remailer`_, but the process should be similar to other pingers you wish to use.
An easy way to do this securely is with curl. First, create a
file called update.sh
in your ~/Mix
directory, with the
following contents:
#!/bin/bash
rm pubring.asc pubring.mix mlist.txt rlist.txt
curl http://lnwxejysejqjlm3l.onion/stats/mlist.txt -o mlist.txt
curl http://lnwxejysejqjlm3l.onion/stats/rlist.txt -o rlist.txt
curl http://lnwxejysejqjlm3l.onion/stats/pubring.mix -o pubring.mix
curl http://lnwxejysejqjlm3l.onion/stats/pgp-all.asc -o pubring.asc
Change the script to executable mode:
chmod +x update.sh
As there is no need to use a certificate for an onion service, you can securely update your remailer stats by simply:
./update.sh
You should update the remailer stats at least once a day when using Mixmaster.
Config File¶
Mixmaster just needs to be configured through the ~/.Mix/mix.cfg
file. A very simple config file could be written as follows:
CHAIN *,*,*,*,*
SMTPRELAY localhost
Chain (Optional)¶
The CHAIN
is the path that your messages will take before being
delivered. In the configuration above, the messages are going to pass
by five mixes, and finally get to the actual target. You can use any
sequence and number of mixes in the chain, passing their names or
simply *
(which means that it could be any mix), separated by
commas.
Note
Adding more mixes to the chain will probably increase the latency to deliver your messages. That is actually not a bad thing, but you should decide how long you are willing to wait to exchange messages.
SMTP Server¶
If you followed Connections (Whonix), you remember that we will
use 127.0.0.1:25
to reach an SMTP server. Using the option
SMTPRELAY
will tell Mixmaster to use that specific connection.
Note
nymphemeral should be ready to tunnel via Tor messages sent using Mixmaster!
You can go to News Server.
