pam_geoip - GeoIP account management module for (Linux-)PAM
account required pam_geoip.so [system_file=file] [geoip_db=file] [charset=name] [action=name] [debug] [geoip6_db=file] [use_v6=1] [v6_first=1]
The pam_geoip module provides a check if the remote logged in user is logged in from a given location. This is similar to pam_access(8), but uses a GeoIP City or GeoIP Country database instead of host name / IP matching. The matching is done on given country and city names or on distance from a given location. With a country database only matches of the countries are possible. This PAM module provides the account hook only. If an IP is not found in the GeoIP database, the location to match against is set to "UNKNOWN, *", no distance matching is possible for these, of course. NOTE: pam just receives a hostname. When trying to find an IP for this name the modules tries IPv4 first, then IPv6. This can be changed with the "v6_first=1" switch. IPv6 support is only available with geoip v1.4.8 or greater, and is has to be enabled by using the "use_v6=1" switch. If a file named /etc/security/geoip.SERVICE.conf (with SERVICE being the name of the PAM service) can be opened, this is used instead of the default /etc/security/geoip.conf. The first matching entry in the geoip.conf(5) file wins, i.e. the action given in this line will be returned to PAM: allow PAM_SUCCESS deny PAM_PERM_DENIED ignore PAM_IGNORE
These options may be given in the PAM config file as parameters: system_file=/path/to/geoip.conf The configuration file for pam_geoip. Default is /etc/security/geoip.conf. For the format of this file, see geoip.conf(5). NOTE: when a file /etc/security/geoip.SERVICE.conf file is present, this switch is ignored (with "SERVICE" being the name of the PAM service, e.g. "sshd"). geoip_db=/path/to/GeoIPCity.dat The GeoIP database to use. Default: /usr/local/share/GeoIP/GeoIPCity.dat. This must be a "GeoIP City Edition" or a "GeoIP Country Edition" file, see <http://www.maxmind.com/en/city>, <http://www.maxmind.com/en/city> and <http://dev.maxmind.com/geoip/geolite> for more information. geoip6_db=/path/to/GeoIPCityv6.dat The GeoIP database to use. Default: /usr/local/share/GeoIP/GeoIPCityv6.dat. This must be a "GeoIP City Edition IPv6" or a "GeoIP Country Edition IPv6" file, see above for more information. use_v6=1 Use IPv6 DB. v6_first=1 Try resolving as IPv6 before trying as IPv4 hostname. charset=CHARSET The charset of the config file, defaults to "UTF-8". Other possible value is "iso-8859-1" (case insensitive). action=ACTION Sets the default action if no location matches. Default is "deny". Other possible values are "allow" or "ignore". For the meanigns of these, see above. debug Adds some debugging output to syslog.
