I assume that this is because NFS does not > maintain an active session table (It uses RPC calls, AFAIK). The "showmount" command can show you which remote hosts are currently mounting, via NFS, which of your exported directories. I don't know, however, whether this qualifies as a "active" session table. It doesn't tell you how recently a file was fetched through each connection, and some of the connections might even be broken but the system doesn't know about that yet.
From rpc.mountd(8), it talks about /var/lib/nfs/rmtab which I suppose has
some relation to showmount, they put it nicely - "it's mostly ornamental" since clients may crash without updating this output or even keep using an open file handle after unmounting the filesystem, that's why I didn't mention this option in my reply. (I love the word "ornamental", reminds me of what catholic priests and Christmas trees have in common). --Amos
