SSH failed login attemps are rate limited by default on Xbian?

[postcd]

When i install Xbian, and enable SSH (to accept logins from other LAN computers), is the Xbian protected from unrestricted SSH brute-force or what are SSH failed login restrictions in place?

Is suggested to install fail2ban or something else?

When trying to install fail2ban, i have got:

Code:
