Is there any scriptable way to know why a connection failed from the source? For example when a failure occurs...to know whether the connection was blocked by the firewall or it made it through but the remote host was not listening.
I submitted some firewall rules today which will be implemented before all the destination hosts are live on the network. In the past I put a perl script on each source server and controlled them from a central location to initiate a connection to each of the destinations to check the connectivity. In this case that will not work.
