In the following example, all alert messages are displayed on the console. Critical messages are mailed to root. Informational and debug messages are added to the /var/log/pamlog file.
auth.alert /dev/console auth.crit 'root' auth.info;auth.debug /var/log/pamlog |
Each line in the log contains a time stamp, the name of the system that generated the message, and the message itself. The pamlog file is capable of logging a large amount of information.
