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

Thank you

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
