I installed on Ubuntu 18.04 with according to this: https://www.ossec.net/downloads/#apt-automated-installation-on-ubuntu-and-debian
I installed both agent and server. Specifically: $ wget -q -O - https://updates.atomicorp.com/installers/atomic | sudo bash $ sudo apt update $ sudo apt install ossec-hids-server $ sudo apt install ossec-hids-agent $ sudo -u ossec ssh-keygen $ sudo vim /var/ossec/etc/client.keys 001 server1 any <some-passphrase-you-save-in-keepass> $ sudo chown root.ossec /var/ossec/etc/client.keys Then I edited ossec.conf as I wrote in my previous mail and started the server. $ sudo /var/ossec/bin/ossec-control start Starting OSSEC HIDS v3.6.0... Started ossec-execd... 2020/03/30 14:05:04 ossec-agentd: INFO: Using notify time: 600 and max time to reconnect: 1800 2020/03/30 14:05:04 going daemon Started ossec-agentd...
