Subject: [Ethereal-users] Newbie ? Looking for NonInteractive sniffer forautomated task

 

I am new to the sniffer world, but would like to create a application which can monitor the network traffic and capture the contents of information sent to a specific printer.  Our company has a "blackbox server" (I have no access to server) which sends detail to a barcode printer.  I would like to use ethereal (or other) to look for the particular ip and save the contents to a file.  I can determine the EndofFile detail to determine when to stop collecting packets.  But I am not sure if there is a command line version which I can configure the parameters (input/output) for my specific application.  Ideally, I would like an agent or process started which continously runs and creates output file when printer info arrives.  I can use Win2000 or unix environment.  Can someone help me determine if Ethereal would meet me needs or provide an alternate suggestion?  Thanks.
