Re: How to send snmpget request from the same source port

Hello Dave,

I have checked the behavior of snmpget with "-Dall" option:

Here's the result of the snmpget
----------------------------------------------------------------------
# snmpget --version
NET-SNMP version: 5.7.1
...
("clientAddr  :4455" in my snmp.conf)
...
# snmpget -Dall -c public -v2c localhost:4000 ...
...

----------------------------------------------------------------------

I think configuration path for snmp is OK.
However, the port is not specified.

Do you think I should modify the source code of NET-SNMP?

Best regards,
