To configure the snmpd daemon to listen on a specific IP address, you can use the agentAddress option in the snmpd configuration file (usually /etc/snmp/snmpd.conf).
The agentAddress option specifies the IP addresses or interfaces that the snmpd daemon should bind to and listen on.
To bind the snmpd daemon to a specific IP address, you can add the following line to the snmpd configuration file:
agentAddress udp:192.0.2.1:161
This will configure the snmpd daemon to listen on the IP address 192.0.2.1, using the UDP protocol and port 161.
You can also use the agentAddress option to bind the snmpd daemon to multiple IP addresses or interfaces.
For example, to bind the snmpd daemon to the IP addresses 192.0.2.1 and 192.0.2.2, you can use the following line:
agentAddress udp:192.0.2.1:161, udp:192.0.2.2:161
To bind the snmpd daemon to all available interfaces, you can use the any keyword, like this:
agentAddress udp:any:161
Keep in mind that the snmpd daemon must be restarted or reloaded for the changes to take effect. You can use the systemctl command to restart or reload the snmpd daemon, like this:
