[opensuse] Log messages

Hi, I want to know if there are log messages for session started and session ending like events in my open suse system. I need to know who was the last user in log in into the system and what time it was when he did it, but I don't know what to search for specifically in my log files. I would appreciate any help you can give me. Thanks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
