Yes, and that's why I said you can't use HiperSockets to connect LPARs in different zones: No firewall. Any time data transits to a different zone, it goes thru a firewall. It is the firewalls that create the zones. Note that "firewall" and "packet filter" are not the same. A host may have a resident IPS/IDS solution, but it isn't a firewall. Firewalls are stand-alone devices. Alan Altmark z/VM Development IBM Endicott

Thanks a bunch Rich for the information! I think the Firewall guys think if we use a Hipersocket than you do not need the Firewall rules.

With EXPORTONLY NO (the default), then anyone can mount anything. Consequently, the export list consists the items in the EXPORT list *and* those things that have been previously mounted. Specify EXPORTONLY YES. That said, I could be persuaded that when DUMPMOUNT NO is specified, the export lists consists only of those items in the EXPORT list, if any.

NFS mount point display
We recently had a network audit reveal the names of the mount points on our VM system (z/VM 5.4). The command they use is showmount -e ip.address It showed all the mount points I have defined to NFS on VM. Is there a way to prevent these mount points from being displayed when showmount is issued? Thanks Steve
