謝謝!我從HP網(wǎng)站上查到
File utmp contains a record of all users logged onto the system.
File btmp contains bad login entries for each invalid logon attempt.
File wtmp contains a record of all logins and logouts.
好像跟你的說法有區(qū)別啊!
再貼last和lastb命令:
The last command searches backwards through the file /var/adm/wtmp (which contains a record of all logins and logouts) for information about a user, a tty, or any group of users and ttys.
The lastb command searches backwards through the database file /var/adm/btmp to display bad login information. |
