I wish I am posting the message to the right place. I am just curious what's the most important reason to choose UDP instead of TCP. And when some error happens, will NFS do retransmission ? thanks. Ronghua

You need to familiarize yourself with the history of NFS. Who, when, and in what kind of environment did invent NFS. (Sun, late 1980es, machines with _very_ low power compared to todays standards, and very slow networks!) Doing NFS over TCP has been a lot more recent development. Yes, when errors (like UDP datagram loss -> response timeout) occur, NFS must do retrying / other error processing.

NFS also supports TCP, just config it to use TCP. - Arnaldo

IIRC only NFS client does. Or is both client and server RPC over TCP already working? ------------------------------------------------------------------------------- Jan 'Bulb' Hudec [off-list ref]
