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:

Starting Authentication failure monitor: fail2ban2023-11-15 12:47:11,251 fail2ban                [8360]: ERROR   Failed during configuration: Have not found any log file for sshd jail
failed!

No, they are not. you can also make life unnecessarily difficult for yourself
Only allow ssh by key instead of password is completely sufficient

No idea why the fail2ban doesn't start, maybe it's because the sshd is started by inetd by default

As long as the Raspberry Pi on which XBian is running is not directly accessible from the internet, it is completely nonsense to install something like fail2ban

Xbian does not have fail2ban pre-installed or configured by default for SSH rate limiting. To enhance SSH security and mitigate brute-force attacks, you can manually install and configure fail2ban by adjusting the SSH log file path in the fail2ban configuration file. Wordle Unlimited
