This is handled by a system setting, which takes care of updating the SSH and Fail2Ban configuration.
This is handled by a system setting, which takes care of updating the SSH and Fail2Ban configuration. Warning! If you modify anything in the /etc/ssh/sshd_config file, even if only the port, yunohost will no longer make and changes to this file. For this reason, always use the yunohost admin tools to make changes to the systems configuration files!
```bash
sudo yunohost settings set security.ssh.port -v <new_ssh_port_number>
