# [SYNOPSIS](#SYNOPSIS)

**pam\_lastlog2.so** \[debug] \[silent] \[silent\_if=<services>] \[database=<file>]

# [DESCRIPTION](#DESCRIPTION)

**pam\_lastlog2** is a PAM module to display a line of information about the last login of the user. The module uses the */var/lib/lastlog/lastlog2.db* database file to store all information.

Compared to pam\_lastlog this PAM module is Y2038 safe and uses sqlite3 to store the information.

# [OPTIONS](#OPTIONS)

**debug**

Print debug information.

**silent**

Avoid all messages except errors and don’t inform the user about any previous login, only update the /var/lib/lastlog/lastlog2.db database.

**silent\_if=<services>**

The argument **services** is a comma separated list of PAM services. If a service is listed here, the last login message will not be shown.

**database=<file>**

Use **file** instead of /var/lib/lastlog/lastlog2.db.

# [MODULE TYPES PROVIDED](#MODULE_TYPES_PROVIDED)

The **session** module type is provided for displaying the information about the last login and updating the lastlog file.

# [RETURN VALUES](#RETURN_VALUES)

**PAM\_SUCCESS**

Everything was successful.

**PAM\_SERVICE\_ERR**

Internal service module error. This includes error reading from or writing to the database.

**PAM\_USER\_UNKNOWN**

User not known.

**PAM\_IGNORE**

Returned by service types which do nothing.

# [EXAMPLES](#EXAMPLES)

Add the following line to e.g. /etc/pam.d/login to display the last login time of a user:

session optional pam\_lastlog2.so silent\_if=gdm,gdm-password

It is up to the administrator to decide if the user can login (optional/required) when **pam\_lastlog2** has returned an error.
