Thanks, I don't know ! Whatever 6.1-RELEASE comes standard with.
After your mail I did cd /usr/ports ; echo */*nfs*
net-mgmt/nfsen net/nfsshell net/pcnfsd net/unfs3
/usr/ports/net/unfs3 offers a non ernel V3 server
but I'd still need a v3 client I suppose ?
Are 6.2-pre or current using V3 NFS then ?
Hints which way to jump / where to RTFM please :-)
