I see that the built-in NFS support registers mountd in portmap only with tcp and not udp. While this makes sense for a TCP-only NFS implementation, it does cause problems for some clients: Ubuntu 10.04 and 7.04 mount just fine. Ubuntu 8.04 gives "requested NFS version or transport protocol is not supported", unless you specify "-o mountproto=tcp" as a mount option, in which case it works just fine. Solaris 2.6 & 7 both give "RPC: Program not registered". Solaris apparently doesn't support the mountproto=tcp option, so there doesn't seem to be any way for Solaris clients to mount. There may be other clients that assume mountd will be contactable via udp, even though they (otherwise) happily support TCP NFS... Thanks, Brent
