That's also one way to see if there are existing servers > where this is big problem. By the way, I took a quick look at SETCLIENTID results from the 4.0 implementations I saw here. Verifiers and clientid's are mostly fairly sparse (lots of zeroes). In more detail: - linux knfsd as we know was affected (now fixed) - ganesha also uses unix time of boot + counters, so I suspect it's also affected - Netapp's clientids and confirm verifiers are very sparse (all but 3 bytes zero in the case I saw), but I can't tell exactly what the scheme is. - Bill Baker tells me Solaris factors in some kind of node id. So it should be OK as long as the client only mounts servers in whatever space the node id's are allocated from. This was added as part of the migration implementation, so older servers probably had the same problem. --b.
