Waiting for a server to shutdown using waitFor

[Krishna Mohan Attravanam <ak...@yahoo.co.in>]

Hi all,

I am using the following tasks within a target that
check to see if the servers are shutdown or not?

<waitfor maxwait="120" maxwaitunit="second"
timeoutproperty="servers.still.running"
checkevery="10">
 <and>
    <not><socket server="${server1.host}"
port="${server1.port}"/></not>
    <not><socket server="${server2.host}"
port="${server2.port}"/></not>
    <not><socket server="${server3.host}"
port="${server3.port}"/></not>
  </and>
</waitfor>

My question is: Is there a deterministic way of
finding out if the server has shutdown completely?
What if the timeout value is not sufficient ? Any
thoughts ?

Thanks
K
