EtherEye is a simple network host checker. You give it some IP addresses or domain names and it'll ping them and give you the results as standards compliant HTML or RSS.

It uses the `ping' command on your system to check if a host is up or not.

You need an operating system with a `ping' command and an installed and configured web server with PHP support. You'll also need to ensure you have support for expat within PHP (if you can't have this, you'll need to use a version of EtherEye prior to 1.5) and PHP safe mode disabled (or the location of 'ping' added to safe_mode_exec_dir in php.ini). EtherEye can run on Linux, UNIX, MacOS X, Windows and many more.

Either all your machines are actually down, or you've not set one or more of the ping command line options correctly. See the installation guide for instructions.

This appears to be caused by a bug in the Windows version of PHP 4.3.9. A work-around was added to EtherEye version 1.1 which should fix it.

This is caused by a bug in EtherEye 1.5. EtherEye 1.5.1 was released to fix it.

Unfortunately nobody has contributed a language file for your language yet. Please see the README for instructions on how to translate EtherEye.

EtherMap was renamed to EtherEye when 1.0 was released as there are lots of projects called EtherMap. Now we have a unique name which is easier to find on Google.

EtherEye is meant to be simple. If you want a more advanced monitoring application, take a look at Nagios.

That depends on the language you're coding in. Basically you need to parse the EtherEye RSS feed, which shouldn't be too difficult.
If you do integrate EtherEye's results into your website, it would be nice if you'd add a link to this site, but you don't have to if you don't want to.

See these instructions.
