Cisco 1924s for sure have "public" as rw string and "private" for ro,
and I'm about 80% sure the 2924 does too.

Many Cisco routers have an snmp "feature" with security ramifications
which Damir Rajnovic has agreed to post to Bugtraq (as of Jan. 1), but I
guess Cisco's lawyers have to hash it out for a few more weeks before
he'll be allowed to. If he doesn't, I will - jc
