GeoIP is a C library that enables the user to find the country that any IP address or hostname originates from. It uses a file based database that is accurate as of March 2002. This database simply contains IP blocks as keys, and countries as values. This database should be more complete and accurate than using reverse DNS lookups. This module can be used to automatically select the geographically closest mirror, to analyze your web server logs to determine the countries of your visitors, for credit card fraud detection, and for software export controls. This port includes a helper script, geoipupdate.sh, to help you keep the library up-to-date.

ifdepd implements dependencies between network interfaces in a reliable way. If any of the source interfaces fails, ifdepd sets all destination interfaces to state down. If all source interfaces are active, ifdepd sets all destination interfaces to state up. For example, it can be used with carp(4) to provide failover functionality on gateways/firewalls. ifdepd is a simple replacement for ifstated and was written because of problems with ifstated.
