Find Failed Login Attempts in Logs by Ron | Aug 1, 2008 | Linux | 0 comments Looking for a log to show you failed login attempts to your Linux machine? Look in: /var/log/btmp You can access it by running: /usr/bin/lastb It’s similiar to the wtmp log of user login/logouts and the utmp log showing who is currently logged in.
