Processes, user programs, and kernels report noteworthy events to files/var/log/messages through Syslog (3. In addition, many UNIX programs create logs. Servers that provide network services such as HTTP and FTP also maintain detailed logs.Common log files are as follows:Access-log: records the transmission of HTTP/WEB data.Acct/pacct: record user commands.Aculog: records MODEM activities.Btmp: the record of failure.Lastlog: records the last successful logon events and the last unsuccessful log

Each time a user logs on, the file is a binary file and needs to be viewed using the Lastlog command, which displays the login name, port number, and last logon time based on the UID. If a user has never logged in, it is displayed as "**never logged in**". This command can only be performed with root privileges. Simply enter the
