If your router responds to `snmpwalk router.isp.net.uk ILMI`, you
probabally will want to do the following to disable it:
   conf t
   snmp-server community ILMI RO 99
   access-list 99 deny any log
(pick another spare access-list if 99 isn't available)

should be RW not RO

Anyone with a Smartnet contract have a response from Cisco yet?  I really
need to get my own Smartnet number.

Cisco was supposed to announce the data tomorrow as I understand it, the
leaks (as they often do) just made the word-of-mouth->closed lists->open
lists trek far quicker.

I'm a bit surprised, however, that it took this long. First rumblings
I heard were weeks ago, in response to it poking up in a "show snmp group".
