Re: Show SNMPv3 users
Hi Giuseppe, Thanks for the inputs. thanks and regards S Sarath On Friday, November 22, 2013 4:37 PM, giuseppe de vito giusepp...@gmail.com wrote: Hi, you can do SNMPWALK on localhost. For example, if you want to use snmpwalk application from a linux shell you can use the command snmpwalk -v3 -u your admin user -l authPriv -A your auth pass -a your auth protocol (MD5 | SHA) -X your priv pass -x your priv alg (i.e. DES) localhost 1.3.6.1.6.3.15.1.2.2.1.3 Option (-l authPriv) must be used if you have configured your admin user to use authentication + encryption. If you have to do so from your software you can use the SNMPv3 API of your programming language (for example for PHP we have the snmpv3_walk function). I think that reading the MIB is more portable than reading the snmpd.conf file that can change filesystem location if you change your distribution or operating system. Reading the MIB let you have the flexibility to change the host where your users are stored: if tomorrow your application will run on a host that is different from the host where snmpd is running then you have to change only an IP address. I hope this will help in your application design. 2013/11/21 sarath azad saraths...@yahoo.co.in 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 On Thursday, November 21, 2013 3:08 PM, giuseppe de vito giusepp...@gmail.com wrote: Hello, SNMPv3 users are stored in the usmUserTable (OID=.1.3.6.1.6.3.15.1.2.2).

Is it a good, to write a function to read the snmpd.conf file to show all the configured SNMPv3 users? Or is there any other API to get the list of SNMPv3 users configured?

Re: Show SNMPv3 users
I second this request. I am trying to configure V3 users and its a real pain. Perhaps this type of function would be nice.
