Hi,
I have been trying to set up a snmpV3 user configuration. So a question you
have no doubt been asked millions of times before.
I have added snmp master agent code to my embedded code, so I have not extended
the snmp agent, nor am I using agentx. I run init_agent, my MIB inits,
init_snmp, init_master_agent, snmp_store and then loop running
agent_check_and_process to process snmp requests. This works fine.
As our setup has a read-only file system apart from one directory, I have used
set_configuration_directory and set_persistent_directory to set up snmpd.conf
files.
I then added rwuser steve1 noauth and rwuser steve3 auth to my snmpd.conf file
that also had rocommunity and rwcommunity settings. I then added createUser
stevev1 and createUser stevev3 MD5 "my_password" DES to my persistent
snmpd.conf file.
When I run my agent I see the persistent createUser lines disappear and the
encrypted data appear as expected.
If I do a
snmpget –v 3 –u steve1 –l noAuthNoPriv –A my_password –a MD5 targetIP
Objectname
on the noauth user, I successfully get the response data.
If I do a
snmpget –v 3 –u steve3 –l noAuthNoPriv –A my_password –a MD5 targetIP
Objectname
on the auth user I get AuthorizationError (access denied to the object)
OR
snmpget –v 3 –u steve3 –l AuthNoPriv –A my_password –a MD5 targetIP Objectname
on the auth user I get Authentication failure (incorrect password, community
e.t.c)
If I do a
snmpget –v 3 –u steve –l noAuthNoPriv –A my_password –a MD5 targetIP Objectname
I get Unknown user name as expected.
So I am a little confused, my user names are obviously being
registered/remembered, but my password apparently is not.
Do you know why this might be happening from the limited info I have given
above?
In my standalone design, do I also need to run some init functions for user
data mib modules?
Regards,
Steve
