When I login in my server using ssh, it shows me a message with the number of failed logins since the last sucessfull login. Currently I have this:
Last failed login: Wed Jan 28 17:54:17 EST 2015 from 18.104.22.168 on ssh:notty There were 1125 failed login attempts since the last successful login.
My question is: is this normal?
Also currently I'm using an ssh key for login. Is there anything more I can do to protect my server?
