op5com/slim-poller_naemon-core-ssh repository overview

⁠Disclaimer

We do not recommend running this version of the Slim Poller. This image includes an SSH server which opens an additional, unnecessary attack vector. Furthermore this is a multi-process image, which is a docker anti pattern. Use https://hub.docker.com/repository/docker/op5com/slim-poller_naemon-core⁠ instead.

⁠Info

This image is a version of the Slim Poller (https://docs.itrsgroup.com/docs/op5-monitor/8.1.0/topics/install/scale-monitor-env.html#Add_a_new_Slim_Poller⁠) with an SSHd daemon inside. You would need to place a configuration file at: /opt/monitor/.ssh/config on the master server to specify the username ( monitor ) and port ( default: 2222 ) for the SSH connection.

Host poller
        HostName poller
        User monitor
        Port 2222

⁠Default password and SSH config

The default password for the monitor user is set to monitor it is highly recommended to change this! We also recommend disabling SSH password authentication after SSH keys have been synced.

sed -i '/^PasswordAuthentication/s/yes/no/' /opt/monitor/ssh/sshd_config
supervisorctl restart sshd

⁠Host keys

SSH hostkeys are located at: /opt/monitor/ssh/. They are generated at container startup if none are found. These keys must be persistent, so setting up a persistent volume for this path is recommended.
