trochu som googlil o tom /etc/shadow subor a nasiel som toto: The ``/etc/shadow'' file contains password and account expiration information for users, and looks like this: smithj:Ep6mckrOLChF.:10063:0:99999:7::: As with the passwd file, each field in the shadow file is also separated with ":" colon characters, and are as follows: * Username, up to 8 characters. Case-sensitive, usually all lowercase. A direct match to the username in the /etc/passwd file. * Password, 13 character encrypted. A blank entry (eg. ::) indicates a password is not required to log in (usually a bad idea), and a ``*'' entry (eg. :*:) indicates the account has been disabled. * The number of days (since January 1, 1970) since the password was last changed. * The number of days before password may be changed (0 indicates it may be changed at any time) * The number of days after which password must be changed (99999 indicates user can keep his or her password unchanged for many, many years) * The number of days to warn user of an expiring password (7 for a full week) * The number of days after password expires that account is disabled * The number of days since January 1, 1970 that an account has been disabled * A reserved field for possible future use co keby som z total commandera rucne upravil /etc/shadow tak aby root nevyzadoval heslo (alebo keby som dal rootovi to iste heslo ake mam ja)?
