MMGEOIP module
Admin Guide
Section titled “Admin Guide”Overview
Section titled “Overview”This module is a lightweight wrapper for the MaxMind GeoIP API. It adds IP address-to-location lookup capability to OpenSIPS scripts.
Lookups are executed against the freely-available GeoLite City database; and the non-free GeoIP City database is drop-in compatible. All lookup fields provided by the API are accessible by the script. Visit the MaxMind website for more information on the location databases.
Dependencies
Section titled “Dependencies”OpenSIPS Modules
Section titled “OpenSIPS Modules”The following modules must be loaded before this module:
- No dependencies on other OpenSIPS modules.
External Libraries or Applications
Section titled “External Libraries or Applications”The following libraries or applications must be installed before running OpenSIPS with this module loaded:
- libGeoIP.
Exported Parameters
Section titled “Exported Parameters”mmgeoip_city_db_path (string)
Section titled “mmgeoip_city_db_path (string)”Path to either a GeoLite or GeoIP City database file.
Mandatory parameter.
...modparam("mmgeoip", "mmgeoip_city_db_path", "/usr/share/GeoIP/GeoLiteCity.dat")...cache_type (string)
Section titled “cache_type (string)”Databse memory caching options. The following options are available:
- STANDARD - Read database from file system; least memory used;
- MMAP_CACHE - Load database into mmap allocated memory; WARNING: this option will cause a segmentation fault if database file is changed at runtime!
- MEM_CACHE_CHECK - Load database into memory; this mode checks for database updates; if database was modified, the file will be reloaded after 60 seconds; it will be slower than MMAP_CACHE but it will allow reloads;
Default value for this parameter is MMAP_CACHE.
...modparam("mmgeoip", "cache_type","MEM_CACHE_CHECK")...Exported Functions
Section titled “Exported Functions”mmg_lookup([fields,]src,dst)
Section titled “mmg_lookup([fields,]src,dst)”Looks up specified fields associated with IP address
specified by the src. The resulting data are
loaded in reverse order into
the dst AVP.
src can be a pseudo-variable or AVP;
and dst must be an AVP.
fields defaults to “lon:lat,” and is a
colon-delimited list of these elements:
latLatitudelonLongitudecontContinentccCountry CoderegRegioncityCitypcPostal CodedmaDMA CodeacArea CodeTZTime Zone
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, ONREPLY_ROUTE, BRANCH_ROUTE,ERROR_ROUTE, and LOCAL_ROUTE.
...if(mmg_lookup("lon:lat","$si","$avp(lat_lon)")) { xlog("L_INFO","Source IP latitude:$(avp(lat_lon)[0])\n"); xlog("L_INFO","Source IP longitude:$(avp(lat_lon)[1])\n");};...Known Issues
Section titled “Known Issues”It is not currently possible to load an updated location database without first stalling the server.
