Description

These options control various behavior of Zorp.

Options

config.options.dscp_prio_mapping

Priority mapping for transferring Differentiated Services Code Point (DSCP, also known as Type of Service or ToS). The low (0), normal (1), high (2), and urgent (3) priorities can be assigned to the DSCP classes. The assigned priority determines the priority of the Zorp thread that handles the connection. The mapping is actually a hash table consisting of the DSCP class ID, a colon (:), the priority of the class (0-3), and a comma (,) except for the last row. For example:

config.options.dscp_mapping =  { 1: 3,
                                 2: 2,
                                 3: 2,
                                 4: 0 }
config.options.language

The default language used to display user-visible messages, e.g., HTTP error pages. Default value: en (English). Other supported languages: de (German); hu (Hungarian).

config.options.timeout_server_connect

The timeout (in milliseconds) used when establishing server-side connections. Default value: 30000 (30 sec)

Cache options

Zorp caches certain data (e.g., to which zone a particular IP address belongs to) to decrease the time required to process a connection. The following parameters determine the size of these caches (the number of decisions stored in the cache). Adjusting these parameters is required only in environments having very complex zone structure and a large number of services. The following log message indicates that a cache is full: Cache over shift-threshold, shifting

config.zone_cache_shift_threshold

Stores IP addresses and the zone they belong to. Default value: 1000

config.inbound_service_cache_threshold

Stores service-zone pairs, and if the service is permitted to enter the zone. Default value: 1000

config.outbound_service_cache_threshold

Stores service-zone pairs, and if the service is permitted to leave the zone. Default value: 1000
