The Graylog Map Widget is the plugin providing geolocation capabilities to Graylog. The plugin is compatible with Graylog 2.0.0 and higher, and it is installed by default, although some configuration is still required on your side. This section explains how to configure the plugin in detail.
In case you need to reinstall the plugin for some reason, you can find it inside the Graylog tarball in our downloads page. Follow the instructions in Installing and loading plugins to install it.
Configure the database
In first place, you need to download a geolocation database. We currently support MaxMind City databases in the MaxMind DB format, as the GeoIP2 City Database or GeoLite2 City Database that MaxMind provides.
The next step is to store the geolocation database in all servers running Graylog. As an example, if you were using the Graylog OVA, you could save the database in the /var/opt/graylog/data folder, along with other data used by Graylog. Make sure you grant the right permissions so the user running Graylog can read the file. Continue reading “Add Geolocation to Graylog 2” »

This lesson describes how to create an installation USB drive for image files provided by Endian and to verify the integrity of the image file. The procedure applies to Windows users with XP, Vista, or Windows7 systems.
You need the following to complete this lesson:
Some USB sticks may not work with Endian devices. In particular, some Endian hardware device might fail to recognise USB Sticks with size bigger the 2Gb. so you should try with one USB stick with smaller size.
Note: ISO image files
Starting with release 5.0, Endian releases installation images as .iso file, rather than .img. However, the following procedure and suggested software can be used also with .iso files.
It is assumed that you have an Endian image file and its correspondent md5sum checksum on your computer. This lesson takes as example an image of an edge 3.0 and its correspondent md5sum file saved in C:\:
In order to create the Endian installation USB flash drive you need to download an application that allows to burn img and iso images to USB flash drives disks, like win32 Disk Imager. Continue reading “Endian Installation USB Flash Drive” »
