Execute a finger query on a server
string $server - The name of the server or the IP-adress
string $query - The finger object to look up
string - the data from the finger request.
The returned PEAR_Error object in case of an error is unspecific, so you can ignore the error code and/or message. The reason for a failure could be a failed connection to the server or the server did not run a finger service.
You will not get a PEAR_Error, if the query fails due to a not existing finger object. This can be only done by checking the data returned by query().
This function can be called statically.
$server = "localhost" ; // or IP adress to use
$query = "ralph" ; // Username to look up
$data = Net_Finger::query( $server, $query) ;
echo $data ;
