I'm not sure what you mean or are asking.
I'm not using nfs...but cygwin.

The file 'zero' is in the same dir as the file 'null'.
I usually read 'zero' and write to 'null, though
for 1-way testing, I read from file 'zero' on the remote
file system and write, locally to /dev/null.

For other direction write to 'null' and read from
/dev/zero locally.
