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.
