It is possible to reboot any device in any Netview map for which you
have a read-write community in the ovsnmp database if that device has a
read-write snmp variable that will trigger it.  It has nothing to do
with Nways. You can do the same through the mib browser. It's the (lack
of) security function in SNMPv1.

You can use Netview's security to limit access to the Nways applications
(and to xnmbrowser), but other than that, or changing the rights mask on
the executable, once the hub view is shown (or the mib browser is run),
whatever rights are enabled by the ovsnmp database are available.

Until you get IPsec and SNMPv3, this will continue to be the case. My
suspicion is that you'll begin to see these on hardware devices and
hardware management applications (whether or not they're in Netview) by
the end of the year.  (My opinion only, not an IBM announcement).

Tnen, the applications will have some additional controls.
