RE: General security usage question

Thanks Dave - that would make our configuration much easier. I had only
tested the "rocommunity" with a community string, didn't realize that
you could add a source [hey, Wendy, read all of the doc next time! ;-) ]

I've changed the IP table in my MIB since I sent it to the list, based
on the feedback about IP and MIB-II information (thanks again for that!)
- we're now returning some physical information (including MAC address,
only for a consistent way to identify the NIC), along with our
definition of 'operational status' and 'link status'. I've removed all
of the IP address information.

Hope your chamber music "marathon" went well!

But that's exactly what "rocommunity" does.
It's just that all the processing is handled under the hood - you don't
see
the details unless you actually look at the VACM tables.

So what you really need to support are the two formats:

rocommunity <string>
and
rocommunity <string> <source>

That would give you the two styles of access control that you've
mentioned, without having to worry about the complexity of the
full com2sec/group/view/access mechanism.

PS: No - I haven't forgotten about the MIB review I promised.
It's just been a busy couple of weeks!
