Hi.Wes,
I used -d at snmpusm command but I got binary print out.
And I used snmpget and snmpwalk with new key, it does not connect with
the agent, but the old key does.
The agent running at 192.168.83.4 is written by Python SNMP, May be the
agent have problem.
The snmpsum result is as following:
#/usr/local/bin/snmpusm -v3 -d -l authPriv -u antenna-agent -a MD5 -A
antenna_authkey -x DES -X antenna_privkey -Ca 192.168.83.4 passwd
antenna_authkey antenna_authtest

I'm not sure without being able to play with the keyboard myself what
went wrong. It would probably be helpful to run it with '-d -l
authNoPriv' and then look at the output packets to determine if there
was an error that wasn't being caught and printed by the tool.
