Offhand I'm not sure of a way to get the server to tell you what version each client is using. You said the client in this case is BSDI which I have no familiarity with, but you used the word legacy which typically implies "old". If it's more than a few years old it's probably using v2. One indicator is if its mount_nfs(8) has options "-2" and "-3". Most of the OS's I've seen that have v3 support have these options so they can still talk to older servers. (Which is useful because I've run into at least one incompatibility between vendors' v3 implementations and have had to force v2 on those clients to get them to work.) In any case if you're trying to copy a 4.3 GB file via NFS and it dies at 2.0 GB, you can bet it's a v2 NFS mount and start looking for a different way to copy the file. Try: dd if=sourcefile | rsh BSDIhost dd of=targetfile -Mitch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
