Creating a Mix configuration

You may create and change a Mix configuration with the config tool. This documents tells you the typical steps that are needed to create your configuration.

Find partners

  • you might ask JonDos or one of the other certification authorities if there are any partners willing to form a cascade with you
  • you could also just write an e-mail to one of the many other operators to make up a cascade with you
  • the mailing list might be helpful to get in touch other operators

General settings

  • First, go to the General panel
  • if you have a Premium Mix, choose "Enable payment"; if you are running a free Mix, let this box unchecked
  • choose the type for your Mix: a first Mix accepts user connections; a last Mix sends our user data to the internet
  • choose a name for your Mix; you might first imagine some kind of name scheme for all of your Mixes (etc. famous artists, TV series characters,...); please do not choose locations on earth as scheme; now choose a short name for your Mix after that scheme
  • if you have a first Mix, you should choose the name of the cascade where it runs now; typical cascade names are composed by the names of Mixes, e.g. Euklid-Rose-ExarKun for the Mixes Eukild, Rose and ExarKun
  • in general, you may leave the InfoService field on its default values
  • set the listener interfaces to the port(s) and hostnames where your mix should listen to; teh recommended ports are 6544 80, 443; first Mixes should listen on all of them

Advanced settings

  • first, go to the Advanced panel
  • choose "Log to Directory" and enter "/home/mix/Mixproxy" as directory (if you follow the usual setup instructions)
  • set "mix" as "user Name on Execution" so that your Mix may switch from the root user to the user "mix"; this might prevent hackers attacking your Mix server to become root
  • set 4096 as Max. nr. of File Descriptors
  • choose "Run as daemon"

If you are running a free Mix, you should also set the traffic shaping values described here.

Certificate creation

  • first, go to the Certificates Panel
  • if you already have an Operator certificate, import it; otherwise, enter your operator information and create an operator certificate
  • enter the information about your Mix here and create a Mix certificate
  • If your operator certificate is not signed yet, please send it to JonDos. You may use the function Tools->E-Mail certificate request... for that.
  • This tools command will put all your public certificates into the clip board; just paste them into an e-mail

Previous Mix

  • first, go to the Previous Mix Panel
  • ask your neighbour Mix operator or JonDos to send you his certificates
  • import these certificates, and check whether the signatures are OK
  • if they are not OK, you might have the wrong certificates; request them again

Next Mix / Proxy settings

  • first, go to the Next Mix / Proxy Panel
  • if you have a First or Middle mix, ask the next Mix operators and/or JonDos for the certificates first
  • the next Mix operator should also send you the connection information (hostname, port) of his Mix, so that you may enter this information
  • if you are running a last mix, you have to enter your proxy settings, instead of a next mix
  • depending on your installation, you might have set up a squid HTTP, proxy, for example, or an additional dante SOCKS proxy
  • for the squid proxy, just create a proxy with host=localhost and port=3128
  • for an additional dante SOCKS proxy, create a second entry with host=localhost and port=1080

Payment settings

First, go to the Payment panel.

If you use the default installation procedure, you just have to change two things:

  • set the database password to the password that you have chosen for aiuser in the installation process
  • let JonDos create you a price certificate that confirms the price for your Mix; JonDos does this if you have a respective contract and if you have sent your public Mix certificates to JonDos (see above, "Certificate creation")

Done! Now your configuration is complete.
