You should be able to come up with a command that tests the port you need for the backup. If you run over ssh, you could do something that will execute quickly like 'ssh r...@target_ip id' or if it is smb, an 'nmblookup -A target_IP' might work. -- Les Mikesell lesmikes...@gmail.com ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
