Yup. >Unfortunately, this message doesn't have any details on what will change (if >anything) in the NWSTG stream. In general? The change is that the NIDS products will stop being encrypted and will start being compressed using zlib. I will be adding zlib uncompression to my NIDS server at the end of November. I should then be ready to go. >I am assuming that they will turn of encryption on 1/1/2001, Yes. >but as usual, details are scarce with the NWS.
