# Fail2ban setup
Fail2ban can be used to ban IPs that try to bruteforce the login page.
Log level must be set at least to `warn`.
Add this filter in `etc/fail2ban/filter.d/opengist.conf` :
```ini
[Definition]
failregex = Invalid .* authentication attempt from <HOST>
ignoreregex =
```
Add this jail in `etc/fail2ban/jail.d/opengist.conf` :
```ini
[opengist]
enabled = true
filter = opengist
logpath = /home/*/.opengist/log/opengist.log
maxretry = 10
findtime = 3600
bantime = 600
banaction = iptables-allports
port = anyport
```
Then run
```shell
service fail2ban restart
```
