geoipupdate
GEOIPUPDATE(1) General Commands Manual GEOIPUPDATE(1)NAME
geoipupdate - a program for updating the MaxMind GeoIP databases
SYNOPSIS
geoipupdate [-v] [-f licensefile]
DESCRIPTION
geoipupdate automatically updates the GeoIP database for GeoIP subscribers. It connects to the MaxMind GeoIP Update server and checks for
an updated database. If it finds an updated database, then it downloads it, uncompresses it, and installs it. If you are running a fire-
wall, it requires that the DNS and HTTP (80) ports be open.
For example
geoipupdate -v
Performs the update in verbose mode.
OPTIONS -v Verbose mode, prints out the steps that geoipupdate takes.
-d Specify a custom directory target to install the GeoIP datafile(s). By default geoipupdate installs to /usr/share/GeoIP
-f Specifies the configuration file that contains the license key. Defaults to /etc/GeoIP.conf
USAGE
Typically you'll want to write a weekly crontab that will run geoipupdate. Below is a sample crontab that runs geoipupdate on each Wednes-
day at noon:
# top of crontab
MAILTO=your@email.com
0 12 * * 3 BIN_DIR/geoipupdate
# end of crontab
To use with a proxy server, set the http_proxy environment variable. E.g.
export http_proxy="http://proxy-hostname:port"
RETURN CODES
geoipupdate returns 0 on success, 1 on error.
FILES
/etc/GeoIP.conf
Configuration file for GeoIP, should contain license key.
