NAME

geoip.conf - config file for the PAM module pam_geoip

DESCRIPTION

The configuration file (by default /etc/security/geoip.conf) contains lines of four items: domain, service, action and location. For a description of these, see below.
When the service specific configuration file ( /etc/security/geoip.SERVICE.conf) is used, the service column must not be present. If this file is present, the default file is not used, even if present on the command line as "system_file=/file/name".
If you need to match on city names containing non ascii(7) characters (like "DE, Köln" or "SE, Växjö"), you can set the character set to use in the module's arguments: "iso-8859-1" or "UTF-8" (the default).
Any (sub-)item except for action or the distance matching can use a single asterisk ("*") to match any value.
domain
A user name, group name (prefixed by "@") or "*" for any user / group
service
A list of services (or "*") separated by "," (NO spaces allowed)
action
"allow", "deny" or "ignore". This is what will be returned to PAM if the location matches:
allow
PAM_ALLOW
deny
PAM_PERM_DENIED
ignore
PAM_IGNORE
location
GeoIP location, separated by ";". This can be:
a country code (uppercased, two characters), "*" or "UNKNOWN"
a country code like above and "," and a city name (or "*"). When using a GeoIP country database, this part must be "*", i.e. the full entry looks like "DE, *".
a distance from a given point, e.g.
 
 50.0 { 51.513888, 7.465277 }
    
 
This is not available when using a GeoIP country database.
The location part can use spaces, but note: city names must be given as in the GeoIP database, i.e. "Mountain View", NOT "Moutain  View" or "MountainView".
The distance is measured in kilometers. In the above example we match a circle of 100 km diameter around Dortmund, Germany (51° 30′ 50″ north, 7° 27′ 50″ east (51.513888888889, 7.465277777777876)). Coordinates west and south are given as negative values. Values must be given in decimal.

EXAMPLE

 #
 # /etc/security/geoip.conf - config for pam_geoip.so
 #
 
 #<domain>   <service>  <action>  <location>
 @wheel      sshd       allow     DE,* ; SE , Nybro 
 @wheel      sshd       allow     SE, Emmaboda; SE,Växjö
 someuser    sshd       allow     50.0 { 51.513888, 7.465277 }
 someuser    sshd       allow     DE,Köln
 otheruser   sshd       allow     SE,Umeå; DK, København
 *           *          ignore    UNKNOWN
 *           *          deny      *
 ## END
or the same as /etc/security/geoip.sshd.conf:
 #<domain>     <action>  <location>
 @wheel        allow     DE,* ; SE , Nybro 
 @wheel        allow     SE, Emmaboda; SE,Växjö
 someuser      allow     50.0 { 51.513888, 7.465277 }
 someuser      allow     DE,Köln
 otheruser     allow     SE,Umeå; DK, København
 *             ignore    UNKNOWN
 *             deny      *
