Just wondering if anyone has IPFilter / nfsd setup properly on their boxes with any beta versions of FBSD.

It is typically not useful to implement firewall rules between NFS servers and legitimate NFS clients.

The large number of RPC services using randomly assigned ports needed by NFS and the fact that machines which trust each other enough to permit filesharing and generally utilize a common set of directory services to keep the user/group mappings synced mean that the NFS server & clients should be considered in the same "trust domain" in most cases.
Right, ok. I suppose I was just being lazy/trying to blanket support all machines on my subnet without having to delve into individual hosts, but that makes perfect sense. rpcbind (and RPC in general) strictly uses ports under 1023--assuming that there are enough allocatable ports available for each RPC service in the port range 1-1023--if running as root, does it not?

Does the same rationale apply for Samba? That's part of the reason why I'm concerned with running a firewall.. I run smbd/nmbd on the server machine.

Either that, or I could switch to another firewall setup (albeit it'd be sort of a pain). Does ipfw / pf work better with RPC than IPFilter?

Also if you suggest 7-CURRENT, what's the CVS tag for that version?

The HEAD of the CVS tree (aka "."). Updating the 7-CURRENT won't have any affect upon firewall configuration for NFS, however.
Right. I was just going to see if there was any improvement in how things were implemented in 7-CURRENT, because maybe the issues that I'm encountering had been 'solved' in 7-CURRENT (although I would probably have more issues with core kernel items as they're under heavy development it appears given traffic on the current@ list).

Thanks Chuck!
