with this topology snmv3 TRAP works without any issues, it's just v3
informs that are creating trouble.
Even v2 INFORM works.
VM1:
root@Ubuntu3323:~# cat /tmp/snmptrapd.conf
authCommunity log,net public
snmpTrapdAddr udp:162,udp6:162
forward default 2.2.2.2:162
createUser feroz SHA feroz123 DE
Anyone tried forwarding V3 informs with snmptrapd?
Can some one share the snmptrapd.conf file?

hi,
Is it possible for snmptrapd to buffer/queue the TRAP's and INFORM's and
perform retry in case of failure to forward them to the destination?
I see "serverRecvBuf", "serverSendBuf","retries" but they don't seem to
work, when used in snmptrapd.conf
I tried as follows, serverRecvBuf and serverSendBuf worked, but
timeout/retries didn't work.
[snmp] timeout 10
[snmp] retries 60
[snmp] serverRecvBuf 425984
[snmp] serverSendBuf 425984
Moreover, I see the value of Recv/Send Buf is getting doubled in "ss
-lumpna" output.

Do the patch mentioned for CVE-2019-20892 in the link below, will fix this
double free crash?
Is it safe to appy this patch?

Hi Bill,
I have only one sub-agent running on the same box.
Let me test by adding the proxy configuration in snmpd.conf that you shared.
i.e:
"proxy udp:127.0.0.1:9 .1.3"
Thanks a lot for your response.

My question is, is there a way to block an agent from responding to
queries ( by timeout), till time the sub-agent connects to the agent.

returns the data in 2sec, we still have another 4 seconds.
We should have got the response in the 3rd to 5th retry.
If I increase the timeout value in snmpwalk command with "-t 3", it works
fine.

Looks like the OID itself is not writable. Can you try with other OID's.

Hi,
On net-snmp 5.8, with the following configuration in snmpd.conf file, which
version of *SHA *(i.e SHA1/SHA-192/SHA-256/SHA-284/SHA-512) is used?
createUser feroz *SHA *feroz123 AES feroz123

IMO we need to revert this patch, as it would cause issues in production.
This is a partial fix.
