This is NeXT-Software-Distribution in view mode; [Up]
Date: Sun 02-Oct-1989 16:03:17 From: Unknown Subject: NeXT Software Distribution In an article in NeXTWeek (inside MacWeek 9/19/89), it was mentioned that NeXT users may be able to buy a software over the phone: > A demonstration version of the program (FrameMaker 2.0) > with the save feature disabled will be included > on Version 1.0 of the system software disk > from NeXT. Users can call Businessland or > Computer Craft to buy the program and get > documentation and a password to enable saving... My questions are: 1. If there is a password to enable saving, how will FrameMaker keep NeXT users from telling other users the password? 2. How does the new software distribution system proposed by Steve Jobs work? Will all the programs and data be encrypted so that a software key is necessary to decrypt them? If this is the case, how does NeXT plan on stopping people from giving other users the software key? Any information on these two questions would be greatly appreciated. Mark Lee, mlee@awamore.cs.cornell.edu >From: silbar@candygram.lanl.gov (Dick Silbar)

The hostid is unique to each system. It could also be based on the ethernet address, which would again be unique to each system. Hostid based encryption schemes are commonly used throughout the workstation software market. Frame uses a hostid based password in its floating license server for Suns to assure that the license server is run on the correct machine. Of course, nothing can stop the determined hacker who likes making binary patches to code - but then I guess the marketing folks figure that the increased sales brought on from such schemes (one of the big reasons I picked frame for our suns was its demo) more than make up for the loses from a determined few. >Mark Lee, >mlee@awamore.cs.cornell.edu

If the hostid is not hardcoded into the machine, I guess it would be ok. What really sucks is something like what Mentor Graphics does which is setup authorization codes that are dependent on the hard- wired nodeID of the Apollo workstation. When that workstation breaks down, your software is unusable on any other node! forgive me if my naivete is showing. ____________________________________________________________________ Have a day. :^| Murat N.

If there is a password to enable saving, how will FrameMaker keep NeXT users from telling other users the password?> The password is a (non-trivial) function of the machine's ethernet address, which is supposedly unique for every machine in the universe. Therefore, one must have a password for each machine such a program is to run on.

When that workstation >breaks down, your software is unusable on any other node! > Well, it is hard coded - on the Suns (I may be wrong, someone correct me if I am), the value is in ROM...I would imagine that its the same for the NeXT. On their Sun Floating License server, Frame allows you to define a backup server so that if the primary server ever goes down, you can start up the license process on the back up. When the license server starts, it first tries to find out if other license servers are running - if one with the same serial number is, it won't start...thus, both the primary and backup cannot be active at the same time. Alas, no "hot" backup, but at least some sort of safety net. Another problem with hostid based copy protection is that when you swap the CPU board, your hostid can change. On Suns this is avoided by replacing the ROM from the dead board in the replacement - that way, even though its essentailly a different system, the hostid remains the same. I don't think, however, this saves you when you upgrade to a new system or do something else which makes the old ROMS unusable. All this generate one very important question to ask when dealing with vendors (like Frame) who use hostid/ethernet based copy protection: "what does it take to transfer the license." This is important becuase you don't want to get stuck with software that becomes obsolete when your hardware does. Of course, the whole floating license server concept is designed to prevent problems like the one you have with Mentor Graphics. You purchase licenses which are not keyed to a particular machine - the license server doles them out on a first come first served basis and makes sure that no more than x copies of the product are in use at one time. Only the license server software is keyed to a particular machine (which hopefully is a more reliable one). I really (hint hint hint Frame) wish Frame had implemented this for their NeXT product - especially since many NeXTs are going to be incorporated in academic and corporate networks...the fact that they didn't implement it indicates a certain level of PC think - that is, treating the NeXT as a PC rather than the networked workstation that it is.

Like disaster striking while swapping ROM's (hey, Murphy, knew you'd drop by today :-). Of course, you can get a replacement ROM, but that takes *time* (I know, 'cause I've tried it) >All this generate one very important question to ask when dealing with vendors >(like Frame) who use hostid/ethernet based copy protection: "what does it >take to transfer the license." This is important becuase you don't want to >get stuck with software that becomes obsolete when your hardware does. And the problem then is: how to design a copy protection scheme that allows transfers, e.g. allows passwords to be called back? /Lars
