Hi,


I used Net-SNMP in my project, and I found that when I had added an snmpv3 user by snmpd.conf (createUser directive), I cannot change the auth/priv password of the user by updating snmpd.conf, even have a restarting the snmpd process.


And then I found this is caused by the usm lists. it seems a global usm lists is used to stored the password, and the list is not belong to snmpd. Even when I stop snmpd, or delete the v3 user, I can get the system usm record which is added by the createUser directive ( I use snmp-walk on 1.3.6.1.6.3.15.1.2.2.1 for checking this).


I know snmpusm tool can update the usm password, but that tool need another RW v3 user. I'm wondering if there's a convenient method to modify the password of an existed v3 user, or delete/cleanup the exited usm list ?


Thanks

Yong
