Hi Rob,

All true as told IMHO - but I have 2 slight issues with
one of the statements you made here, the last one.

With all due respect, SNMP is not something we
inherited 'from the time when the entire Internet was
a trustable network'. SNMPv1 had weak control mechanisms
*built into it* because its power 'to do evil' was
foreseen by the IETF working group....

The other issue is that the Internet was never the
type of network you described IMNSHO....it has always
been 'untrustworthy'.

Not picking on you, just feeling cagey today I guess. :-)
