These are the "hacker" tools, commonly used to demonstrate vulnerabilities
in NFSv3.  We are extending them to do the same in NFSv4.  The tools work
with auth_sys mounts but are completely defeated by auth_krb.  These, plus
pynfs with some test scripts, are intended to meet deliverable D1),
"identify tests for v3 security holes, show v4 does not have them."

mount:
This is the standard linux mount command, extended to allow mounting by file
handle.  This is used to bypass the export security built in to the mount
protocol (v3) or pseudo-fs traversal (v4).  See the Readme for build and
usage instructions.

filesnarf:
This is a file sniffing tool from the dsniff test suite.  It passively
sniffs rpc traffic and reconstructs file contents.  We have extended it to
display the contents in real time.
