Dear Mr Powers and Bugtraq, > My Motorola SB4100 handled the SNMP test suite well up until test-case 900, > upon which it locked up completely. > > I had to disconnect and reconnect the power cord to bring it back online. I > haven't tried the rest of the suite yet. Amazingly, my SB3100 stood up to the entire test suite of 10600 cases without a hitch, and apparently has not suffered any ill effects. Incidentally, it took me a while to find the test suite, interested parties can find it here: http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/index.html#download > To my cable company's credit, they recently restricted SNMP access across > the subnet my cable modem resides in.

My ISP, who shall remain nameless for now, appears to have left SNMP of all their customers' modems wide open. They are on RFC1918 private addresses, so not reachable from the Internet at large, but I'd bet that a few of our users are running a UDP echo service which could be used to send nasty packets to everyone else. > NT4's SNMP service crashes around test-case 2358.
