I vaguely recall Isilon mentioning they had something they used for "hardening" their NFS server. I have no idea what that was (or even if it was them;-), but it would be interesting to have something. CITI at UMich have a Python test suite for NFSv4 and I (again, vaguely:-) recall it does try various kinds of bogus/garbage args. It might be one starting point. Could it qualify as a Google SOC project for next summer? (hint, hint...I haven't got the time to do it.) rick
