[comp.protocols.tcp-ip] PC-NFS NET PCNET command

robert@pvab.UUCP (Robert Claeson) (10/19/87)

I just entered the command "NET" on a PC with PC-NFS. It showed me the
'usage' list. Among the options there was a "PCNET [ON | OFF]". I couldn't
find any reference to this in the manual. Anyone who knows what this
does? I have PC-NFS 1.0.

	My PC-NFS V2.0 manual says that 'net pcnet [ on | off ]' allows
PN-NFS to run simultaneously with the IBM PC Network Program. Which IBM
PC Network Program is anybodys guess - I'm somewhat ignorent on what IBM
offers...

It's actually a small performance issue. We tried installing PC-NFS in
a PC and then running the IBM PC Network Program (talking to a Sytek
card) on top of it. The PC Network program thinks that the PC-NFS
drives are local PC disks, which allows it to publish them to other
nodes on the PC Network and gateway through to the NFS world. It turned out
that the PC Network program did certain directory searching operations
in a rather unusual way that caused us to flush our own directory search
cache rather faster than usual, slowing down directory searches on the PC 
Network clients. We added some code to our own directory search logic to
cater for this; since it was sub-optimal for other applications we added
the NET PCNET ON|OFF feature to toggle its use.

The IBM product is actually named "The IBM PC Network Program". The part # of
the PC Network Technical Ref. Manual is 6322916. I do not have the part # for
the actual product, but you can obtain it from your local IBM rep.
