# fail2ban



## Checking if someone is in jail

You have multiple jails - the one I'm usually interested in is `sshd`:

```shell
sudo fail2ban-client status sshd
```

## Removing from jail

```nil
sudo fail2ban-client -i
```

then in interactive mode:

```nil
status sshd
set sshd unbanip XXX.XXX.XXX.XXX
```
