how to find who logged in SSH in the last nite?
How do I find out who login last 24 hours? Someone has access to my server via SSH. I have over 200 customers on plesk. None of them have SSH access.someone put ssh brute force files in /var/tmp/ and there is /var/tmp/.bash_history of what they typed in ssh. The owner & group of those files are "apache". I can't find who did it.
