Use 'last'. It will display logins, time of the logins, source of the ip address, and duration of the login. If you want to know what each user did/typed on your machine, you need to install process accounting as linux does not log that info.

Be aware that anyone with root priviliges can and probably will erase/modify the log files. You can set syslog up to send its logs to a remote server which only you have access to (and ideally only console access, no remote access allowed at all). Read the syslog.conf man pages for more details.

There is also BSD style process accounting, but it doesn't seem to be used much and must be specifically compiled into the kernel.
