SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free.
Statusmap Icons
The base install of Nagios doesn't have any fancy icons for use on the statusmap so we'll add some to make a nicer display.
NagiosExchange has a nice collection of image packs. If you want, you can create your own, but we're going to use a pre-made set of generic icons for routers, servers, etc. Whatever the case, download your icons to /usr/local/nagios/share/images/logos. For the statusmap, you must have icons in the GD2 format.
To enable the icons, we'll create an extended host info file to contain the extra details our hosts will need at /usr/local/nagios/etc/hostextinfo.cfg.
At this point, we aren't going to bother with map coordinates, notes or any Extended Host Information options other than statusmap_image. So the basic definition will be:
define hostextinfo{
host_name <host alias>
icon_image <icon image filename>
vrml_image <icon image filename>
statusmap_image <statusmap image>.gd2
