Re: How to clean USM config

[Rajmohan Banavi]

If you want to delete the existing v3 user list, then you can
delete/move/rename the persistent snmpd.conf file (typically in
/var/net-snmp/ folder) which contains the hashed list of the users.

How to clean USM config

[徐 勇]

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
