OVERVIEW
========
Tellme - get all the lowdown details on an address
Tellme is used to discern what a computer is running,
 and also to help track down servers.
It combines together into one place traceroute tools,
 head requests, server examination, and whois lookups.

TellMe is used widely in default Plesk installs as a bundled
3rd party add on.

  render_Open("WHOIS");
 if ( $q_Host )
  passthru(EscapeShellCmd("whois " . $q_This));

3. information disclosure

TellMe discloses path information in error output, echoing
 back the full path to the script.
