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) 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
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.
