I have been looking for an implimentation of NFS for the AT&T 3B2 computers that run system V.[2,3]. I called Lachman Associates and they told me that they don't sell to individual end users. Does anyone know of such a product exists, and if so where I can get it and how much it is?

It's pretty straightforward, given the specifications. In fact, the server could work in user mode, allowing any with sufficient disk storage to act as an NFS server. The client would need hooks into the file system in order to recognise the remote-request vs. local calls situation. One way around that is something we're running locally called PDU (Portable distributed Unix). Since I'm not sure whether or not this stuff is proprietary, I can't discuss it here. However, as they claim inspiration from the Newcastle Connection, I'll discuss that instead :-) [I just started work here, and I've got to cover my rear end...] Essentially, one makes a new libc.a where the system calls related to files (open, read, write, etc.), are replaced by code containing the intercept logic. You can then recompile and relink your (user) code with this new library, giving it remote capabilities. RPC and XDR have been made publically available by Sun (Don't remember if they placed it in the Public Domain or not). One problem is that RPC runs on top of UDP. It would be nice if the SysV networking stuff had some sort of datagram service (Or even a decent virtual circuit). I estimate about 25 person-hours to write the server on top of RPC. I'm willing to contribute 10 person-hours of that total. Anyone game for the rest? Regards, Binayak Banerjee {allegra, ihnp4}!mtgzz!bba bba@mtgzz.ATT.COM
