We hope this has been helpful, and if you wish us to expand on this, please leave your requests in the comments. If you want to see if your ban is working take a look at: fail2ban-client status sshd Our config is fairly strict by blocking it for 7 days but you can adjust this to your own requirements. This now should mean your proxmox host is more secure with the IP being blacklisted if the password is entered wrong 3 times. Once done we need to restart fail2ban systemctl restart fail2ban Next we need to create the file: /etc/fail2ban/filter.d/nf nano/etc/fail2ban/filter.d/nfįailregex = pvedaemon\[.*authentication failure rhost= user=.* msg=.* Within this we place our config for blocking Brute Force attacks on the two service ports. Once this is installed we need to add our config to: /etc/fail2ban/jail.local nano/etc/fail2ban/jail.local On proxmox fail2ban is really easy to install: apt-get install fail2ban As we have that GitLab server running in a LXC container on a ZFS based system (Proxmox VE). For example when using VMWare EXSi it will block the SSH port by default and when open add some strict rules on access.Īs such, for our proxmox servers we wanted to increase security on the two open ports: SSH port 80 & Web Portal port 8006 (The Proxmox Web Management Portal). Fail2ban jail to mitigate DoS attacks against Apache. Out of the box Proxmox does not have any Brute Force protection in the same way as some other virtualisation technologies do.
