# ghostlist.cgi(1)

CGI program to view ghost clients

## NAME

ghostlist.cgi - CGI program to view ghost clients

## SYNOPSIS

**ghostlist.cgi**

## DESCRIPTION

**ghostlist.cgi** is invoked as a CGI script via the ghostlist.sh CGI wrapper.

It generates a listing of the Xymon clients that have reported data to the Xymon server, but are not listed in the *[hosts.cfg(5)](/hosts.cfg/5.md)* file. Data from these clients - called "ghosts" - are ignored,  since Xymon does not know which webpage to present the data on.

The listing includes the hostname that the client reports with,  the IP-address where the report came from, and how long ago the report arrived.

By far the most common reason for hosts showing up here is that the client uses a hostname without a DNS domain, but the hosts.cfg file uses the hostname with the DNS domain. Or vice versa. You can then use a **CLIENT** setting in the hosts.cfg file to match the two hostnames together.

## OPTIONS

- \--env=FILENAME

  Loads the environment defined in FILENAME before executing the CGI script.
