Administering a large installed base of MikroTik routers can be difficult. You can use The Dude, but this has not been updated in some time, and MikroTik have not made their long term intentions clear in relation to the continued development of the software.
We use Ansible internally to remotely configure machines, so it seemed a natural choice to update the firmware of the MikroTik routers we have installed.
Firstly, you need to generate an appropriate DSA SSH key. Refer to: MikroTik Wiki for full instructions.
From the source server, test the SSH connection works:
If you do not immediately connect, you may need to add the appropriate identity file to ~/.ssh/config
Then attempt re-connection.
You should see the MikroTik banner message and the [admin-ssh@remotesite] > command prompt. Just disconnect for now:
Once the connection is working OK, we can then add the relevant routers to /etc/ansible/hosts. In our setup, these are in the [mikrotik] group.
The actual playbook we use is very simple. It checks if package updates are available, and if so, updates the MikroTik. BE CAREFUL – it reboots the remote router when the task is complete.
