We're having a problem with resolving a name to an address with a Linux apps. We have an activity where we're moving images from one company network to another. We have been trying to ensure all references to domain names have been changed, but we're still getting an error and so we're thinking we've missed one (or more). Is there something that can trap attempts to resolve a name to an address we can turn on or check (either on our server or the network)? I'm not even sure if a sniffer might help, but we're looking for any ideas that people may have.
