string as index of a table
Hello, Could you please if it is advisable to use a string eg. name of item as a table index? The table is yet to be defined, need defined and added to a MIB file. The table will contain info of different items and our requirement is if we can get the info of a particular item by doing snmpget query passing the item name string as index. I have tested it, it is feasible, but while giving the OID in snmpget, we needed to give the item name string index by dot separated ascii values of each character in the name. eg. OID of the table .1.column no..5.65.66.67.68.69 where the item name is ABCDE. But from usage perspective it is not looking good that we need to manually calculate the ascii values of the characters in the item name and provide them in the snmpget query. Is there any other way of doing this so that we can directly give the item name and not the ascii values? Some thing like: OID of the table .1.column no..5.ABCD or OID of the table .1.column no..5.A.B.C.D thanks and regards S Sarath-- Comprehensive Server Monitoring with Site24x7.

Re: problem in SNMPSET on table with string data type columns
Hi Bill,
Could you please provide a sample outline or example of how to create, register
and use a serialize handler?Here do we need to use the function
netsnmp_register_instance for each of the column in the table to have
separate handler for each column to be called for each of them separately,
rather than a single handler function being called passing all the varbinds in
input SNMPGET/SET query?

But if we are giving columns in different order like “snmpset

Re: error showing SNMPWALK on the last table of a view
Hello, Thanks for the replies and inputs. The problem was that the table being of very large size, SNMPWALK was taking more time to finish. When we configured the view to contain only a single column of the table, and then doing SMNPWALK on that column of the table, we were getting the data from that particular column. Once that column is done, SNMP-get-next (internal to SNMPWALK) tries to get the next column data. But that column is not there in the view, so it continues to search for next valid data present in the view , till the end of the table. As the table is of very large size, it takes very long time to return and in the mean time SNMPWALK query gets timed out. Initially we tried with : snmpwalk -t 10 ... but we go same timeout problem. But when tried with snmpwalk -t 20 ... it worked . So there is no problem with our code, its the general behavior only. thanks and regards S Sarath On Wednesday, June 25, 2014 11:28 PM, Fulko Hew fulko@gmail.com wrote: Can't saw if this is yr problem but I have seen that it has linear?

Re: bug in trapsess directive?
Hi Paul, I too have observed this that trapsess directive, was requiring the engine-id for properly sending the traps. Otherwise, though we were able to generate and send the traps from our device, but they were not able to be detected at the receiving manager. Once we gave the engine-id of our device (trap generating device) in trapsess directive, the traps were successfully received at the manager. In case of SNMPv3 traps the engine-id the sending device (trap generating device) needs to be used in trapsess, which will be common for all the traps generated from our device.

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.

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. 2013/11/21 sarath azad saraths...@yahoo.co.in Hello, Could you please tell, in a program, what is the best method to show all the SNMPv3 users configured?

Re: not able to receive SNMPv3 traps for SHA, and priv users
Hello, I have got the solution to this problem. The problem was that for configuring SNMPv3 traps, i was adding below in the snmpd.conf file: trapsess -u username -l security level host IP It was working well for MD5, but for SHA auth and priv (both DES AES) it was sending a trap , but it was getting error which receiving at the manager saying that authentication (for SHA) or decryption (for MD5 + DES/AES) failure. If we are configuring the 'trapsess' with the engine-id then it is working well for all these auth (MD5,SHA) and priv (DES, AES), as below: trapsess -e engine-id -u username -l security level host IP thanks and regards S Sarath From: sarath azad saraths...@yahoo.co.in To: net-snmp-us...@lists.sourceforge.net net-snmp-us...@lists.sourceforge.net; net-snmp-coders@lists.sourceforge.net net-snmp-coders@lists.sourceforge.net Sent: Friday, September 27, 2013 10:41 AM Subject: not able to receive SNMPv3 traps for SHA, and priv users Hello, I am using net-snmp version 5.4.2.1.

Re: which is better way to create SNMPv3 users
Hi Anish, Thanks for the reply. My requirement is to create SNMPv3 users when ever needed, and not just at the Agent start up. Also if I am creating a user using SNMPUSM command, I am able to create, but they are not persistent across a Agent restart. Once i created a user using SNMPUSM I have tried to send signal -HUP to snmpd process to see if the new user is getting updated in the persistent snmpd.conf file, but it was not updating. Any idea how to make the users created by SNMPUSM copied to persistent snmpd.conf file, so that it will be persistent across the Agent restart. I am thinking about this option of using SNMPUSM as it doesnot require restart of the Agent process.

Re: which is better way to create SNMPv3 users
Hi Anish, I am able to create new users using SNMPUSM, but the newly created users are not persistent. That is, if the snmp agent is restarted the users created using SNMPUSM are not there. Also the persistent snmpd.conf file is not getting updated with the users created SNMPUSM, even after giving -HUP signal to snmp agent process (snmpd). Could you please suggest a way to have these users created with SNMPUSM be persistent?

When I am sending continuous flow if snmp traffic (packets/queries) the process SNMPd is getting unresponsive after some time and we are restarting it. But after some 30-35 restarts the AgentX is getting blocked in at the call : agent_check_and_process(Operation::AGENTX_BLOCK_TILL_SNMP_PACKET_ARRIVE); Inside which its getting blocked at the write system call writing to a pipe inside netsnmp_callback_send.

Also from debug log I have noticed that we have far more calls to write to the pipe that the reads from the pipe. So is it that the pipe is getting full as we are reading less than the write operation, and causing the last write to block? How to handle this situation? Please advise.
