PAM_FILTER(8) Linux-PAM Manual PAM_FILTER(8)NAME
pam_filter - PAM filter module
SYNOPSIS
pam_filter.so [debug] [new_term] [non_term] run1|run2 filter [...]
DESCRIPTION
This module is intended to be a platform for providing access to all of the input/output that passes between the user and the application.
It is only suitable for tty-based and (stdin/stdout) applications.
To function this module requires filters to be installed on the system. The single filter provided with the module simply transposes upper
and lower case letters in the input and output streams. (This can be very annoying and is not kind to termcap based editors).
Each component of the module has the potential to invoke the desired filter. The filter is always execv(2) with the privilege of the
calling application and not that of the user. For this reason it cannot usually be killed by the user without closing their session.
OPTIONS
debug
Print debug information.
new_term
The default action of the filter is to set the PAM_TTY item to indicate the terminal that the user is using to connect to the
application. This argument indicates that the filter should set PAM_TTY to the filtered pseudo-terminal.
non_term
don't try to set the PAM_TTY item.
runX
In order that the module can invoke a filter it should know when to invoke it. This argument is required to tell the filter when to do
this.
Permitted values for X are 1 and 2. These indicate the precise time that the filter is to be run. To understand this concept it will be
useful to have read the pam(3) manual page. Basically, for each management group there are up to two ways of calling the module's
functions. In the case of the authentication and session components there are actually two separate functions. For the case of
authentication, these functions are pam_authenticate(3) and pam_setcred(3), here run1 means run the filter from the pam_authenticate
function and run2 means run the filter from pam_setcred. In the case of the session modules, run1 implies that the filter is invoked at
the pam_open_session(3) stage, and run2 for pam_close_session(3).
For the case of the account component. Either run1 or run2 may be used.
For the case of the password component, run1 is used to indicate that the filter is run on the first occasion of pam_chauthtok(3) (the
PAM_PRELIM_CHECK phase) and run2 is used to indicate that the filter is run on the second occasion (the PAM_UPDATE_AUTHTOK phase).
filter
The full pathname of the filter to be run and any command line arguments that the filter might expect.
MODULE TYPES PROVIDED
All module types (auth, account, password and session) are provided.
RETURN VALUES
PAM_SUCCESS
The new filter was set successfully.
PAM_ABORT
Critical error, immediate abort.
EXAMPLES
Add the following line to /etc/pam.d/login to see how to configure login to transpose upper and lower case letters once the user has logged
in:
session required pam_filter.so run1 /lib/security/pam_filter/upperLOWER
