General Panel
This panel contains some general options.
General Settings
- Mix type
The mix type defines in which place in the cascade your mix will be located. A cascade
consists of at least a first and a last mix, but may contain additional middle mixes.
If you choose your mix to become a last mix, please be aware of the fact that you
are the first one to be contacted by law encforcement in case of misuse done by users
of the service. As a last mix you will also have to install a
cache proxy if you do not use
MixOnCD where such a proxy is already integrated.
- Mix configuration
You may choose between two configuration types: static and dynamic. In a static
configuration, you have to send your certificates and IP address to and receive the same
information from your neighbour mixes before you can start your mix. If you choose
dynamic, this information is automatically transfered by the Info Service network
to each mix in the cascade and you have very little communication effort. The disadvantage
of this concept is, that, except for a last mix, you also have very little influence which
cascade your mix is assigned to (only minimum length of cascade and position in the cascade).
Please note that this is an experimental feature that won't work in most cases!
- Allow dynamic fallback
This is only available in static configurations and allows for a temporary dynamic
configuration if one or more mixes in the statically defined cascade are not available
for some time.
Please note that this is an experimental feature that won't work in most cases!
- Mix name
Please give your mix a human-readable name.
- Cascade name
Dependend on the type of configuration, the first or the last mix has to define a
human-readable name of the whole cascade.
- Minimum cascade length
In case of a dynamic configuration, this option defines the minimum length of the cascade the mix may be assigned to.
Please note that this is an experimental feature that won't work in most cases!
Info Service
These fields contain the connection information that is needed to reach an InfoSerivce. The Info Service is not important to set up the cascade, but it tells the JAP users that this cascade exists and gives them additional information about it (length, number of users, mix organisations, mix locations). If no Info Service reachable, it is not possible to use a dynamic mix configuration as the needed information cannot be sent or received to/from the mixes.
- Host name
Either an IP address or a DNS name.
- Port
The port on which the Info Service is reachable.
Listener Interfaces
The listener interfaces are needed to tell the mix on which ports it should listen to connection requests from JAP users or a previous mix. For each listener interface you may specify the transport protocol, host name, port and visibility. You may specify as many listeners as you want.
- Transport protocol
In almost all cases, TCP + RAW should do the thing. If you really need to use the UNIX domain sockets, you should know what you are doing...
- Host name
If you have chosen to use MixOnCD, you won't need to insert anything here. Otherwise, you must enter the IP address of your mix.
- Port
The port on which your mix is listening. We suggest you to create listeners on the ports 80, 443 and 6544. Please note that in UNIX/Linux systems, you must start the mix as root user to bind it to ports lower that 1024.
- Visibility
If your mix is not connected directly to the internet but is behind a router in a local area network (LAN), the internal IP address of the LAN differs from the external IP address your mix is visible from the internet. In this case, you will have to specify two listener interfaces for each port you are listening to: one virtual interface, that contains the host name visible from the internet, and one hidden interface, that contains the internal host name. The virtual host name will be transfered to the JAP users by the Info Service.
If your mix is behind a NAT gateway, you may also need to define port forwarding for the mix listener ports on your router. Please consult the router manual for further details.
