I guess the first question is what sort of proof would be satisfactory. If we can cite parts of the code, would that help? Or does this person need something with a more solid, mathematic basis? (I have to admit that the word "proof" is tripping me up here.) > First, if one does FTP or scp to transfer files between the zones, > how can I prove it doesn't hit the NIC or wire?

I would check for calls to put(9F) and putnext(9F) from within the IP module (which includes TCP). > Second, the same proof (not sure why he thinks this but...) for a > filesystem lofs mounted in both zones (from the global zone) and can > just copy files back and forth between the zones without hitting the > NIC/wire. "huh?" Perhaps the right question in response is: "what problem are you seeing, and what are you trying to do?" It's quite unclear to me what would prompt a question about lofs that looks like the above. -- James Carlson, KISS Network <[EMAIL PROTECTED]> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ zones-discuss mailing list [email protected]
