That would probably work. You should try CVSup though - its a much more efficient use of bandwidth and its really easy to use.

Maybe a > problem on the server (2.1.7) side ? Hmm. I just fixed a bug like that in 3.0 but that bug was definately not present in 2.1.x. I am not supporting the NFS in 2.1.x at all really, so I don't know what it could be. The NFS in 2.2 and 3.0 is really much better than 2.1. It supports the newer version 3 protocol which has much better write performance (2-3 Mb/sec on my unloaded 100baseTX test network). I am also actively supporting this version and will try to fix any bugs which I can reproduce. > > I also used the dumbtimer option with no success.

You might consider subscribing to the cvs-sys@freebsd.org mailing list so that you can see when fixes are committed to the tree. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
