Socket connections

[Rowan Chattaway]

Hi, I'm having a little trouble with Socket's!
public boolean isConnected(String ipAddress)
{
final int dayTimePort = 13;
final int pingPort = 7003;
final int telnetPort = 23;
BufferedReader in = null;
Socket socketComputer = null;
try
{
socketComputer = new Socket(ipAddress, dayTimePort);
//in = new BufferedReader(new InputStreamReader(socketComputer.getInputStream()));
//String timeStamp = in.readLine();
return true;
}
catch(UnknownHostException e)
{
return false;
}
catch(IOException e)
{
return false;
}
}
This is used to check whether any of our critical systems have gone down, the boolean returned is used to determine what image and set of actions to do/display on the intranet site I'm developing.
The above code works fine, however testing it by giving it a fake ipaddress, i.e. one that doesn't exists( to act as a 'down' system) - the socket connection takes ages to conclude that it can't make a connection. This causes trouble by causing the page to display very very slowly.
Can anyone think of a way of improving this?
Any help would be very much appreciated!
Rowan.
