Examples of org.apache.commons.net.FingerClient

org.apache.commons.net.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; } 
```
