org.apache.commons.net.finger.FingerClient
public class FingerClient
The FingerClient class implements the client side of the Internet Finger Protocol defined in RFC 1288. To finger a host you create a FingerClient instance, connect to the host, query the host, and finally disconnect from the host. If the finger service you want to query is on a non-standard port, connect to the host at that port. Here's a sample use:
    FingerClient finger;
    finger = new FingerClient();
    try {
      finger.connect("foo.bar.com");
      System.out.println(finger.query("foobar", false));
      finger.disconnect();
    } catch(IOException e) {
      System.err.println("Error I/O exception: " + e.getMessage());
      return;
    }

             throws IOException
 query(longOutput, "") .
 
longOutput - Set to true if long output is requested, false if not.
IOException - If an I/O error occurs while reading the socket.
