# Step 5: Setting up fail2ban

We are now going to setup fail2ban, basically something than bans IPs from accessing your server if they fail to authenticate multiple times.

#### Installing
Installation varies from distro to distro, [here you can check how](https://github.com/fail2ban/fail2ban/wiki/How-to-install-fail2ban-packages).

#### Configuration
We are going to setup fail2ban to check ssh connections. You can configure it for many many things, even custom ones.

You can add this to `/etc/fail2ban/jail.d/jail.local`:
```
[sshd]
enabled = true
```
Restart fail2ban with `sudo systemctl restart fail2ban`, and it should work! You can check that the jail is set up properly by running `sudo fail2ban-client status`.
