HowTo install the mix server software for FreeBSD/Jail

This HowTo describes the installation of the mix server and related software for FreeBSD using Jails. We prefer the installation of related software from ports (not packages), because compilation does not take much time and ports are sometimes more up to date than packages. The software for mix servers for FreeBSD is distributed as source code.

Requirements

To compile the mix sources the libraries OpenSSL (at least v.0.9.7) and Xerces-C++ are required. Additionally a C++ compiler, automake and subversion are required, too. It may be useful to install subversion from ports, to disable BDB.

cd /usr/ports/security/openssl && make install clean
cd /usr/ports/textproc/xerces-c2-devel && make install clean
cd /usr/ports/devel/automake19 && make install clean
cd /usr/ports/devel/subversion && make install WITHOUT_BDB=YES && make clean

For premium mixes PostgreSQL database server, client and C-libraries for PostgreSQL clients are required, too.

cd /usr/ports/databases/postgresql84-client && make install clean
cd /usr/ports/databases/postgresql84-server && make install clean
cd /usr/ports/databases/postgresql-libpq++ && make install clean  

Compile the source code

Checkout the latest stable version from our subversion repository. We recommend the use of the directory /home/mix for sources.

mkdir /home/mix
cd /home/mix
svn checkout https://svn.jondos.de/svn/proxytest/proxytest/branches/stable

Afterwards compile and install the mix software:

cd /home/mix/stable
./configure --enable-new-channel-encryption --enable-new-flow-control
make
make install

Enable additional features

Depending on the features needed by your mix, you can enable some more features for your mix:

 ./configure --enable-new-channel-encryption --enable-new-flow-control --enable-payment .... ....


Mandatory feature for premium services:

  • --enable-payment Specifies to build with payment support.


Monitoring your mix:

  • --enable-server_monitoring Specifies to build with state tracking for server monitoring. You can specify a monitor port in the mix configuration (usually port 8080) and fetch a XML file from this IP:port time by time to check your mix. A plug-in for Nagios, which is using the monitoring port, will be found in the mix source tree misc/nagios.


Additional Logging features:

  • --enable-crime-detection Enable crime detection mode. Crime detection parameters can be specified in the mix configuration file. Do ONLY use it, if you are under constraint by authorities and law. For working properly, all mixes of a cascade have to enable this feature.
  • --enable-dataretentionlog Enable log messages according to data retention law.


Other features:

  • --enable-bandwidth-limitation Specifies to build with last mix bandwidth limitation. The limitation parameters can be specified in the mix configuration file. (only exit mixes)

Create a system user account

It is not a good solution to run the mix server with root privileges. Create a new system user account (recommended name: mix) and specify this user account in the mix configuration file. After startup, the mix server will switch to this UID.

Create a system user account with useradd:

adduser --quiet --system --disabled-password --shell=/bin/false --group mix

Create a log directory

The directory and file for log messages will be specified in the mix configuration file. You have to create the directory and set safe permissions:

mkdir /var/log/mix
chown mix:adm /var/log/mix
chmod 0750 /var/log/mix

No logrotate configuration is necessary. The mix server creates a new file, if the log file size exceeded the configured limit.

Start the mix server

You have to create a mix configuration, become root, raise the number of max. open descriptors to the value specified in the mix configuration file and you can start the mix.

For Csh (FreeBSD default) use:

limit descriptors 32768
mix -c /path/to/config.xml

If Bash is installed and preferred, use:

ulimit -HSn 32768
mix -c /path/to/config.xml

After startup the mix server will switch to the sytem UID specified in the mix configuration file.

Update the mix software

Like other software the mix is updated time by time. New features will be added, bugs will be fixed ... and so on. Join the operator mailing list to stay up-to-date about software updates. If an update is announced, run the following steps.

cd /home/mix/stable
make distclean
svn update
./configure  --enable-new-channel-encryption --enable-new-flow-control --enable-server_monitoring --enable-payment .... ....
make
make install

After successful update restart the mix.

HowTo install squid proxy (only exit mixes)

The squid proxy can be installed using the ports system. Do NOT install squid3, please use the latest stable version of squid v.2.7. Only for testing purposes lynx may be installed, too. Perl-Template-Toolkit is needed to process the config template file. Alternatively you con do this job by hand.

cd /usr/ports/www/lynx && make install clean
cd /ports/www/p5-Template-Toolkit && make install clean
cd /usr/ports/www/squid && make install clean
options for Squid are: SQUID_AUFS / SQUID_COSS / SQUID_LARGEFILE

Add a line to /etc/rc.conf

squid_enable="YES"

Make a backup of the original squid.conf.

cd /usr/local/etc/squid/
mv squid.conf squid.conf.orig

Replace the configuration file with an optimized configuration and add the block list squid-block.acl. You may find the squid configuration files provided by Jondos GmbH in the mix source code, subdirectory misc/FreeBSD/ of the mix source code. There are two squid.conf templates: one template for free services and one for premium services. Choose the suitable template and replace all occurrences of [% extIP %] by the external IP address of your server. You may use tpage from the Perl Template Toolkit for this job. In the example the template for free services is used and the external IP address is 123.123.123.123. Alternatively you may do this job by hand.

cd /home/mix/stable/misc/FreeBSD
tpage --define extIP=123.123.123.123 squid.conf.free.template > /usr/local/etc/squid/squid.conf
cp squid-block.acl /usr/local/etc/squid/

Afterward create the cache directories and wait, until the cache is created....

squid -z -d -3

... and start the squid proxy.

/usr/local/etc/rc.d/squid start

... and check if squid is working.

http_proxy=http://127.0.0.1:3128; lynx http://www.anonymous-proxy-servers.net

Update the JonDonym block list

Time by time the JonDonym block list will be updated. You will receive a notice by the mix operator mailing list.

cd /home/mix/stable
svn update
cp -f misc/FreeBSD/squid-block.acl /usr/local/etc/squid/squid-block.acl
/usr/local/etc/rc.d/squid restart

HowTo install Dante SOCKS proxy (only premium exit mixes)

The Dante SOCKS proxy can be installed from the ports tree.

cd /usr/ports/net/dante && make install clean

Add a line to /etc/rc.conf

sockd_enable=“YES“

Keep a copy of the original sockd.conf.

cd /usr/local/etc/
mv sockd.conf sockd.conf.orig

Install the configuration file sockd.conf provided by JonDos GmbH. It contains the JonDonym block list and blocks port 25. You will find the sample configuration file in the subdirectory misc/FreeBSD/ of the mix source code. Replace all occurrence of [% extIP %] by the extern IP address of your server. You may use tpage from the Perl Template Toolkit for this job. In the example the extern IP address is 123.123.123.123. Alternatively you may do this job by hand.

cd /home/mix/stable/misc/FreeBSD
tpage --define extIP=123.123.123.123 sockd.conf.template > /usr/local/etc/sockd.conf

And now start the Dante SOCKS proxy.

/usr/local/etc/rc.d/sockd start

Updating the JonDonym blocklist

If an update of the Jondonym blocklist is necessary the configuration sockd.conf must be renewed as well:

cd /home/mix/stable
svn update
cd misc/FreeBSD
tpage --define extIP=123.123.123.123 sockd.conf.template > /usr/local/etc/sockd.conf
/usr/local/etc/rc.d/sockd restart
