So far as I know, Linux supports only NFS2, and against the SUN-NFS2- specifications, the writes are buffered. FreeBSD supports NFS3, this solves this problem in another way. I think it's possible to tell FreeBSD NFS2-Server to buffer the NFS-writes too... but didn't know where you can find it (I didn't prefer this) Bye Stefan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
