# pam\_lastlog2(8)

PAM module to display date of last login

## NAME

pam\_lastlog2 - PAM module to display date of last login

## SYNOPSIS

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

## 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

**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

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

## 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

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.
