Hi,
I've been testing the v2c implementation of this current release
using SilverCreek. In order to test full R/W access from a remote
machine, I had my public group set to R/W also.
On one of SilverCreek's tests, entitled: "SET read-write objects",
it seems that NET-SNMP failed to handle SET instructions involving
erroneous data.
What happened is that "snmpd" crashed when SilverCreek tried to SET
(perhaps, invalid) values into the server. Here are test log details
of what SilverCreek is doing when the crash occurred. Included also
is the generated /var/log/snmpd.log.

sysDescr: Test Machine [192.168.63.119:SNMPv2c]
2.4.x The purpose of these tests is to verify that the agent
returns the correct error-status when the test intentionally
writes variables. The tests are run on each of the read-write
variables returned in 2.1.2.1.
2.4.1 This test issues SET using the current value of the variable.
The expected outcome is for the agent to return noError.
(Note: some objects with peculiar semantics, e.g. tcpConnState,
will return wrongValue instead of noError).
