One is the client, one is the server :-) No, really. Both 3.18.1, 64it, same userland/compiler/etc. and even same CFLAGS for both kernel and userland. I built tcpdump on both (from packages) and ran them back to back literally 10 seconds apart. What "encoding" are we talking about here? The NFS RPC encoding? (everything I know & remember about NFS is 15+ years old..) thanks, Holger
