To update the Wazuh manager IP address, edit the following file:
|
|
$wazuh_conf
|
|
|
|
And change the <address> tag to point to your Wazuh manager:
|
|
<address>$YOUR_WAZUH_MANAGER_IP</address>
|
|
|
|
Then, register the agent with your Wazuh manager:
|
|
/var/ossec/bin/agent-auth -m $YOUR_WAZUH_MANAGER_IP
|
|
|
|
Finally, restart the Wazuh agent:
|
|
systemctl restart wazuh-agent
|
|
|
|
