Protecting the web interface with fail2ban

aptitude install fail2ban

Create, if does not exist, the file jail.local (settings in this file takes precedence over identical settings of jail.conf. Use jail.conf as a template, copying and enabling into jail.local what you are interested in. Note that jail.conf could be overwritten by fail2ban package updates, jail.local will not)

Add the following string to the end of this file /etc/fail2ban/jail.local :

[proxmox3]
enabled = true
port = https,http,8006
filter = proxmox3
logpath = /var/log/daemon.log
maxretry = 3
bantime = 3600 # 1 hour

Create the file /etc/fail2ban/filter.d/proxmox3.conf :

[Definition]
failregex = pvedaemon\[.*authentication failure; rhost=<HOST> user=.* msg=.*
ignoreregex =

You can test your configuration with the command :

fail2ban-regex /var/log/daemon.log /etc/fail2ban/filter.d/proxmox3.conf

Restart fail2ban:

/etc/init.d/fail2ban restart
