Configure pam_lastlog. Edit /etc/pam.d/sshd or /etc/pam.d/common-session (if included from sshd) and make the following changes: - if pam_lastlog is not present, add it: "session required pam_lastlog.so showfailed" - if pam_lastlog has the "silent" option specified, remove it. - if pam_lastlog does not have the "showfailed" option specified, add it.
