I am trying to connect a PC to a VAXstation3100 using PC NFS. I have
succesfully managed this with an HP machine. I think all I require is
a copy of the DEC pcnfsd to run on my VAX. Where can I get one ??

I could be missing something fundamental, but here goes. As I understand it, PC-NFS is a package which allows a PC to access NFS services offered by any NFS host. You don't need to change anything at the host-end. The PC is just another client. So, as I see it, there is no such thing as a "PCNFSD" which will run on the DEC box. (I assume you're talking about a DEC box running Unix; I know nothing about VMS issues). -- _______________________________________________________________________________ Ajay Shah, (213)734-3930, ajayshah@usc.edu The more things change, the more they stay insane. _______________________________________________________________________________

PC-NFS actually goes through a secondary authorization process which requires a daemon on the host to accept a packet containing a userid and 'slightly' encrypted password and respond with a flag indicating if the user is authorized, as well as what uid and gid is assigned to the account. SUN distributes the source for this process freely, it is implemented using SUN's RPC/XDR libraries. I've recently run into this problem on my VAXstation 3100 running DEC's VMS/Ultrix Connection. I cannot compile suns daemon process, because the DEC UCX software provides an rpc library based on Apollo's implementation of the same procedures. If anyone has come across a way to map XDR onto NIDL I would be _very interested_!! I'm amazed that UCX implements NFS server and packages it with NCS rpc! Maybe there is a level of compatability there that is not immediately apparent. -Kent Cearley -University of Colorado

DEC had been involved with the NCS camp for a while; perhaps they decided not to bother porting the ONC RPC libraries, and just ported the NCS RPC libraries. Sun *does* freely distribute the source to the user-mode ONC RPC/XDR code for UNIX (available from assorted FTP sites, and also, I think, available from Sun for the cost of a tape); if you have the time, patience, and experience with UNIX and VMS needed, you may try porting it. (Note: the above is not equivalent to "Sun freely distributes the NFS source"; the RPC/XDR source does *NOT* include the NFS server or client code, and I don't think it includes the BSDish-kernel-level RPC implementation - you have to pay money for that.)

Well there's been a lot of discussion here about running PCNFSD (which you really do need to run PC-NFS) and more about getting the required rpc-services with it. We're running Apollo's which use the NCS system, but then I'm just an ignorant peasant. I took the sunrpc3.9 sources from uunet.net.uu (I think) compiled and installed them. (We did have the Apollo NFS system already, so I took care of not overwriting the real portmapper) After that I took pcnfsd from the same address, compiled it. And that's about it. No husle no nothing, just run a go. (sound like an add :) ) If you can't get hold of the source in the USA, try our site: ftp.eb.ele.tue.nl [131.155.2.25] the sources should be in: /pub/apollo/.....
