Configuring Fail2Ban for ProFTPd

Suppose Fail2Ban is already installed, if not, then see my article – Installing and Configuring Fail2ban.

In Fail2Ban by default, there are already filters for ProFTPd and it knows that the log file is located at /var/log/proftpd/proftpd.log, so it’s enough to create the file:

sudo nano /etc/fail2ban/jail.d/proftpd.local

And enter the data below, thereby activating the check of the log file /var/log/proftpd/proftpd.log:

enabled = true
bantime = 86400

Restart Fail2Ban to apply the changes:

sudo service fail2ban restart

You can check the status:

sudo fail2ban-client status proftpd
