Re: Show SNMPv3 users

Hi Giuseppe,

Thanks for the reply.
For getting the user details from a remote system, we may do SNMPWALK on this OID. 

But if on the same device where snmp agent is running (where we are doing the SNMPv3 configuration), if we want to get the user details, do we need to do snmpwalk on localhost for this OID or is there any other method also.

Currently I am doing the SNMPv3 configuration using snmpd.conf file and so thinking to implement the "show user details" functions by reading the snmpd.conf file. But is it the correct method which will work in all cases, or is there any other better methods.

thanks and regards
S Sarath

Hello,
SNMPv3 users are stored in the usmUserTable (OID=.1.3.6.1.6.3.15.1.2.2).
This table has the following entries

usmUserTable
  +----usmUserEntry(1)
            +-----usmUserEngineID(1)
            +-----usmUserName (2)
            +-----usmUserSecurityName (3)
            +----- ..... (see http://www.net-snmp.org/wiki/index.php/TUT:SNMPv3_Options for details

You are looking for the usmUserSecurityName and, for a complete list of such items, you can walk the usmUserTable over
the same field; for example you can execute

snmpwalk .1.3.6.1.6.3.15.1.2.2.1.3

to obtain all configured users in the usmUserTable.

I hope this will help.
