sshd[31757]: Accepted password for user from x.x.x.x port 51435 ssh2
sshd[31757]: pam_unix(sshd:session): session opened for user user by (uid=0)
sshd[31757]: lastlog_filetype: Couldn't stat /var/log/lastlog: No such
file or directory
sshd[31757]: lastlog_openseek: /var/log/lastlog is not a file or directory!
