How to configure net-snmp to expose the agentx_send_ping() function

OS: Linux Net-SNMP version: 5.7.3 Build Env: OpenEmbedded yocto I am trying to build a sub agent that generates traps for events originating from another process. I do not want to start trying to generate traps until the snmpd agent is running. So I am trying to use agentx_send_ping() to detect w

which the trap thread could send a message to generate a trap, on the main loop processing. Hope this helps others, that might run into the same issue. Larry On Thu, Mar 15, 2018 at 4:42 PM Larry Hayes wrote: > OS: Linux > Net-snmp version: 5.7.3 > > I have written a sub age

Behavior of snmptrapd and snmpd when using certificates (TSM, DTLS)

Hello, I am using net-snmp v5.8 r0. I think I have successfully configured an snmpd server to generate V3 Traps/Informs using TSM with certificates and have an snmptrapd receive those V3 Traps/Informs. As I can see the Trap/Infom data dumped to the window snmptrapd is running. My issue is, when

Re: running a script with a dynamic parameter

Have you tried this in your snmpd.conf file: exec [MIBOID] NAME PROG ARGS OR sh [MIBOID] NAME PROG ARGS exec and sh extensions can only be configured via the snmpd.conf file. They cannot be set up via SNMP SET requests. If you look in the snmpd.conf man pages, you will find more detail

Re: Subagent not connecting back to Master Agent.

The select will update the time spec: tvp. So if it did timeout the values will be 0. You need to reset the values after each timeout. If the select is interrupted and does not time out, then the remaining time will be in the tvp. On Thu, May 21, 2020 at 2:10 PM Himanshu Sharma < himanshusharma1

When a token is put in a conf file that does not expect it, you have to prefix it with the tag of the file it is supported by. (Not sure I worded that correctly) But try: [snmp] clientaddr 10.10.163.10 On Tue, May 26, 2020 at 5:41 PM Ganesh Lakshmanan wrote: > > Hello All, > > I created a snm

I also create V3 users with the procedure you indicate. When you stop snmpd, it writes the persistence file. So you cannot edit that file while snmpd is running. The procedure that works for me: 1) Stop snmpd 2) Wait for PID of snmpd to go away, if you have a large number of V3 users, it lengthens

You will need to create the SNMP V3 user. See: https://net-snmp.sourceforge.io/wiki/index.php/TUT:SNMPv3_Options for a tutoria on configuration setup. You might also want to check your access control: https://net-snmp.sourceforge.io/wiki/index.php/Vacm On Tue, Aug 9, 2022 at 3:48 AM 김동휘 wrote:
