[Isms] TBD secshell

["David B Harrington" <dbharrington at comcast.net>]

Hi,

The EOP need to be updated to deal with two ports.

There is a potential issue I have not yet researched; the transport
model establishes the 
connection. But the transport model does not know the operation type.
So how will it know which port to use? Of course, we have the port in
the transport address, so it can just work from that basis, but I am
not sure it knows what it needs to know to do that. In one case it
needs to act as an ssh client; in the other it needs to act as a
server - and that means the transport model needs to know which type
of operation. This violates the RFC3411 architecture established by
the SNMPv3 WG, and it has serious ramifications on other potential
models for various subsystems; it is not in scope to modify how those
other subsystems work.
