Hello all,
Is it possible to dynamically amend user details in an SNMP4J agent?
I have an Agent, overriding BaseAgent, which currently defines a single
SNMP user:
protected void addUsmUser(USM usm) {
UsmUser user = new UsmUser
new OctetString(username),
AuthMD5.ID,
new OctetString(password),
null,
null);
usm.addUser(user.getSecurityName(), user);
}
I can use this user quite happily to get/set values in my MIB tree.
But, it is possible to dynamically change the user's password? I've
tried using the snmpusm command line tool (from the net-snmp library) as
follows:
snmpusm -v3 -lauthNoPriv -xDES -aMD5 -A<password> -u<username>
192.168.10.10:16001 -Ca passwd <password> <newpassword> <username>
But this fails with:
Error in packet.
Reason: commitFailed
Failed object:
SNMP-USER-BASED-SM-MIB::usmUserAuthKeyChange."...p....*"."<username>"
Could I reasonably have expected this to work?
Assuming that I can get this to work - does SNMP4J provide any direct
support for obtaining the user details from a file? (So that I can
remove the code which creates the user each time the agent starts).
Thanks in advance for any help!
Alistair.
